SAFETY PRECAUTIONS General

2-2

*

Read this Operator’s Handbook and learn the operating characteristics and limitations of the machine. Know what operating clearances the machine requires.

*

Read the CIMA Safety Manual and follow the recommended safety precautions.

*

Know clearances of all side and overhead obstructions such as wires, bridges, etc., for operating safely.

*

Always know all traffic rules, signs, flags and hand signals used on the job and know who has the responsibility for signalling.

*

Be aware of operating hazards that weather changes can create on the job.

Know proper procedures to follow when a severe rain or electrical storm strikes.

*

Never attempt to operate or work on a machine when not feeling physically fit.

*

Know what safety equipment is required and use it. Such equipment may be: Hard hat, safety glasses, reflector type vests, respirators and ear plugs.

*

Never wear loose clothing, rings, watches etc., that might catch levers and controls and cause loss of control.

*

Keep hands and controls free from water, grease and mud to assure nonslip control.

*

Handle fuels and lubricants carefully and clean up spills to avoid fire and slipping hazards.

*

Clean any mud, grease or oil from controls, handrails, ladders and decks.

Lash necessary tools securely and remove all loose items before operating machine.

*

Never carry passengers on the machine.

WARNING The protection offered by the roll over and falling object protective structure may be impaired if it has been subjected to any modification or damage.

Twin Hitch Safety Precautions *

Do not operate machine with the bail down, except when coupled to another machine, as this results in a dozing action, bending the bail and causing unnecessary damage to hitch assembly and machine.

*

Never park or leave the machine with the bail in the raised position. Bail can be dropped by accidental control lever movement, or loss of cylinder air pressure, and could be dangerous to any personnel in the area of the bail. If the machine is being parked for an extended period of time, or being serviced with the air supply (engine) shut off, the bail, if left in the raised position, will eventually drop to the lowered position of its own weight. Always lower the bail when dismounting the machine for any reason.

Note: Holes are provided in the side plates of the push plate assembly for propping the bail in the raised position with a pin, for servicing procedures.

*

Twin hitch scrapers are designed to operate in pairs of the same size and type. Twin hitch operations with unequal size scrapers, three or more scrapers in train or push tractor assistance could seriously impair the service life of the machines.

2-3

*

Never turn the machine when hitched to another machine. The machines must remain in a straight line while hooked together as turning of either machine will damage the bail of the rear machine.

*

Keep bowl as low as possible, but high enough to clear objects in the haul road, as this increases ground clearance of hitch push plate and bail assembly on the front of the machine.

*

Scraper team should alternate pushing and pulling functions during loading cycles to equalize wear of the attachments on both machines.

Preventing Fire Hazards General Fire Precautions * Make sure machine has a fire extinguisher and that it is accessible and fully charged. (Not furnished with machine).

2-4

*

Never use an open flame as a light anywhere on, or around, the machine.

*

Clean all dirt, oil, grease and other fluids from systems and components to minimize fire hazards and aid in spotting loose or leaking lines, fittings etc..

*

Check the engine compartment for rubbish, oily rags or other debris that could cause fires before starting the engine.

*

Don’t let greasy, oily rags or similar hazards accumulate in the cab.

*

If the machine has been operated with an under inflated tyre. Make sure that the tyre has cooled sufficiently before parking and leaving the machine unattended.

Flammable Fluid Precautions * Do not use diesel fuel or other flammable fluids for cleaning purposes. Use approved, nonflammable solvents. *

Make sure all fluid system caps, drain cocks, valves, fittings, lines etc., are secure and leak free.

*

Never use an open flame (match, lighter etc.) when checking fuel, lubricant, coolant and battery fluid levels or when checking for fluid leaks. Use a flashlight or other safe lighting only.

*

Shut off engine and use extra caution if engine is hot when refuelling. Ground the hose spout to prevent sparks when spout is touched to fuel tank filler tube.

*

Never smoke while checking or adding fuel or other fluids or handling fluid containers and lines.

*

Use care and do not stand downwind when adding fuel or other flammable fluids to tanks and reservoirs to avoid fluids being blown or splashed onto clothing.

*

Close fuel tank shut-off valves, if used, before servicing fuel system.

*

When preparing machines or components for storage, seal and tape all openings and close containers tightly to seal in all volatile inhibitor fluids and compounds used.

*

Follow manufacturer’s recommendations when handling and using enginestarting fluids and disposing of spent containers. Do not puncture or burn empty containers. These fluids are explosive and highly flammable.

2-5

Electrical Hazard Precautions * Never smoke or allow open flames or sparks near batteries. *

Leave battery box open when charging batteries in machine for adequate ventilation of explosive gas (hydrogen) produced.

*

Always disconnect batteries before repairing electrical system to avoid danger of fire-causing sparks. Disconnect battery ground cable first and reconnect last.

*

Always disconnect battery equalizer, batteries, ECU electrical connections and alternator leads before carrying out any welding on the machine.

Disconnect ground cables first and reconnect last.

*

Never check battery charge by placing metal objects across battery posts to avoid sparks at battery posts.

*

Use jumper cables only as recommended. Improper use can result in battery explosion or unexpected machine motion.

*

Never operate engine starter for more than 30 seconds and allow two minutes between cranking periods for cooling. An overheated starter could cause a fire.

*

If electric coolant or lubricant heaters are used, be sure to follow heater manufacturer’s recommendations for use to avoid electrical and/or fire hazards.

*

Always shut off the engine when leaving the machine unattended. Apply the parking brake, place the shift lever in the 'Neutral' position, lower the bowl to the ground, place the battery master switch in the 'Off' position and block all road wheels.

*

Match speed to road conditions.

*

Yield the right of way when required. Always give loaded machines the rightof-way when your machine is empty. On narrow or hilly roads, loaded machines should stay next to the high wall. Obey the rules of the road.

*

Always be sure the bowl is in a travel position high enough to clear any obstacles in its path. If in doubt as to clearance, stop the machine and check clearance.

*

Brake firmly in one application. Frequent and repeated light applications may exhaust air from reservoir faster than it can be replaced by the compressor.

Never operate the machine if a warning light or gauge indicates low air pressure.

*

Stay in gear when driving downhill. Do not coast with transmission in neutral.

Select the proper gear and maintain safe speed with the service brakes or/ and retarder. Always maintain safe speeds for haul road operating conditions for maximum control. Reduce speed before turning.

*

Always operate straight up or down slopes whenever possible, side hill operation can cause sideslip and possible roll-over. If the machine starts slipping sideways, turn down-hill immediately.

*

Stay as close to the side of the road as possible. Pass other equipment only when the road is clear and enough room and reserve power are available.

*

Use accessory lights and devices at night or in poor visibility. Carry a flare kit.

Do not overdrive your headlights.

*

Always deflate tyre before attempting to remove any embedded objects or removing the tyre and rim assembly from the machine.

*

Always use a self-attaching chuck with a long airline and stand to one side while the tyre is inflating.

*

Always relieve pressure before servicing any pressurized system.

*

Always attach a 'DO NOT OPERATE' or similar warning sign to ignition switch or a control before cleaning, lubricating or servicing the machine.

2-11

Wheels and Tyres If tyres on a machine were inflated at the factory with dry nitrogen gas, the tyre walls will be marked 'N' and the following factory installed decal will be found mounted on the fenders.

NOTICE TYRES ON THIS MACHINE ARE FACTORY INFLATED WITH DRY NITROGEN. IT IS RECOMMENDED THAT DRY NITROGEN BE USED EXCLUSIVELY FOR ALL TYRE PRESSURE ADJUSTMENTS AS WELL AS INFLATION OF REPLACEMENT TYRES. Nitrogen gas improves tyre pressure retention, increases tyre life by reducing carcass oxidation from within, minimizes rim rust, and has no known detrimental effect on the tyre. It also reduces the potential of a tyre explosion because it is an inert gas and will not support combustion inside the tyre. The same tyre inflation pressure used for air inflation should be used for nitrogen inflation. Refer to Section 160-0050, 'NITROGEN INFLATION OF TYRES' of machine Service Manual for recommended procedures for inflating and pressure adjusting tyres with dry nitrogen gas. Only proper nitrogen charging equipment operated by personnel trained in its use should be used.

2-12

WARNING Never mix components of one manufacturer’s rims with those of another. Using the rim base of one manufacturer with the lock ring of another or vice versa is dangerous. The lock ring of one may not fully engage with the lock ring groove of the other. Always consult the rim manufacturers for proper matching, assembly and safety instructions.

Also, use and servicing of damaged, worn out or improperly assembled rim assemblies is a very dangerous practice. Failure to comply with the above warnings could result in an explosion from tyre pressure causing serious property damage and serious personnel injury or death.

Whenever a machine’s tyre(s) is (are) exposed to excessive heat such as a machine fire or extremely hot brakes, the hazard of a subsequent violent tyre explosion must be recognized. All nearby persons must avoid approaching the machine so as not to be physically endangered in the event of an explosion of the tyre and rim parts. The machine should be moved to a remote area, but only when this can be done with complete safety of the operator operating or towing the machine. All other persons should stay clear of the machine. The fire or overheated brakes, wheel etc., should be extinguished or cooled from a safe distance. Do not attempt to extinguish the fire or cool the machine by use of hand-held fire extinguishers. If it is absolutely necessary to approach a machine with a suspect tyre, approach only from the front or the back. Stay at least 15 m (50 ft) from the tread area.

Keep observers out of the area and at least 460 m (1 500 ft) from the tyre sidewall. Refer to the accompanying sketch. The tyre(s) should be allowed at least eight (8) hours cooling time after the machine is shut down or the fire extinguished before approaching closer.

MACHINE CONTROLS Braking

Service Brake Pedal

The dual safety brake system installed on this machine is applied using the service brake pedal or park/emergency brake control lever, or automatically should the air pressure drop below 5.2 bar (75 lbf/in²) to slow or stop the machine. For effective braking, the air system pressure gauge should read around the centre of the green zone 7.2 - 8.6 bar (105 - 125 lbf/in²). If the gauge indicates a pressure drop for extended periods or the Low Air Pressure warning light illuminates, the machine should be shut down until the fault is corrected.

Service Brake This is a floor mounted pedal operated by the left foot. Depress the pedal as required by speed, load and road conditions to slow or stop the machine. Release the pedal as the machine slows until, when stopped, the pedal is depressed just enough to hold it stationary. Do not 'FAN' the pedal, as this needlessly wastes the air supply in the reservoirs.

1294

WARNING Never release the park/ emergency brake or move the machine until the needle is at least approaching the centre of the green zone.

Park/Emergency Brake This is a modulated brake control valve, located on the right hand dash panel. When the lever is moved towards the 'PARK' position, there is a gradual increase in brake application until the lever is fully back in the 'PARK' position and the brakes are fully applied. The brake lights are automatically applied. To release the brakes, move the lever forward to the 'RELEASE' position.

Note: Moving the lever to the 'PARK' position will apply the brakes to stop the machine, but this should be done only in emergencies; never for normal braking. For normal braking the service brake pedal should be used.

WARNING Always apply the park/emergency brake before leaving the operator's seat.

3-15

Engine Electronic Foot Pedals There are two electronic foot pedals mounted on the cab floor. The electronic foot pedals provide an electrical signal to the engine's fuel control system in proportion to the degree of pedal actuation. The right hand pedal operates the tractor engine and the left hand pedal operates the scraper engine. The right hand (tractor) accelerator pedal can be operated individually when only the tractor engine is running, however, when both engines are running, it is recommended that both pedals are depressed at the same time to provide equal power to both engines. This action is obtained by depressing the left hand accelerator pedal which, by means of a linking bar, also depresses the right hand pedal.

Note: The electronic controlled engine will override the electronic foot pedal position until the engine is warmed up to the correct operating temperature. The engine MUST be started with the foot 'OFF' the electronic foot pedal.

HEUI Electronic Management System This machine is equipped with the HEUI electronic management system which continually monitors the engine and warns the operator when a problem develops.

The system also takes action to prevent damage to the engine and, provides the serviceman with diagnostic capabilities so that problems can be corrected quickly and easily.

WARNING When turning, depress only the tractor accelerator pedal. If both pedals are depressed, the scraper engine will continue to power forward in the original direction, forcing the tractor unit to tilt over.

WARNING Before any welding is done on a machine equipped with the HEUI electronic management system, disconnect the following in this order: Battery earth cable, battery supply cable, alternator earth cables, alternator supply cables, front & rear transmission ECU connectors (located behind access door below cab door) and front & rear engine ECU connectors (located on LH side of engine). Turn off battery master switch before disconnecting any components.

After welding connect all of the above in the reverse order.

HEUI Electronic Management System - Description 1. Electronic Control Module (ECM) - Receives electronic inputs from the driver as well as from sensors that provide information electronically, such as oil pressure and temperature and intake manifold pressure. This information is used to control both the quantity of fuel injected and injection timing.

2. Programmable Read Only Memory (PROM) - Located in the ECM and encoded with the operating software. Additional information is programmed into the EEPROM. This information controls the horsepower rating, torque curve, maximum engine speed and engine protection devices. The ECM processes this information and sends electronic signals to the Electronic Fuel System Injectors where the precise amount of fuel is injected into the engine.

3. Electronic Fuel System Injectors - The injector is a lightweight, compact unit that injects diesel fuel directly into the combustion chamber. The amount of fuel injected and the beginning of injection timing is determined by the ECM. The ECM sends a command pulse which activates the injector solenoid.

The injector performs four functions: a - Creates the high fuel pressure required for efficient injection. b - Meters and injects the exact amount of fuel required to handle the load. c - Atomizes the fuel for mixing with the air in the combustion chamber. d - Permits continuous fuel flow for component cooling.

Electronic fuel system injectors are self compensating and virtually eliminate engine tune-ups.

Note: Never apply 12 or 24 volts directly to terminals on the injector or engine sensors as they will burn out. Before removing injectors, the fuel passages must be blown out to prevent fuel flow from entering the cylinder head.

3-18

HEUI Electronic Management System - Operation When either 'Stop' engine light on the dash panel illuminates, the computer has detected a major malfunction in the respective engine that requires immediate attention. It is the operators responsibility to shut down the engine to avoid serious damage.

The machine is equipped with an engine protection system, which records fault codes when an out-of-range conditions is found. The stop engine and check engine lights illuminate when the engine protection system is initiated. If a fault occurs within the tractor engine, resulting in a loss of power and speed, then the scraper engine will rampdown in accordance, as a safety feature, allowing the operator to maintain full control of the vehicle. The operator MUST shut down the engine, at the first safe opportunity, to avoid serious damage.

The engine should not be restarted after it has been shut down after activation of the engine protection derate system unless the problem has been diagnosed and corrected.

Conditions that will cause the Stop Engine light to come on are; Low coolant level, High coolant temperature, Low oil pressure and High oil temperature.

Whenever the Check Engine light or Stop Engine light comes on, the Electronic Management System computer will determine where the problem is and will store this information in its memory. If the malfunction is intermittent, the lights will come on and go off as the computer senses the changing engine condition.

The operator can check for fault codes by turning the ignition key switch to the 'OFF' position, pressing the diagnostic request switch 'ON' and holding it down, turning the ignition key switch to position '1' and then releasing the diagnostic request switch. Do NOT start the engine.

To retrieve any active or inactive (historic) codes recorded, press the diagnostic request switch. The fault codes flash in the following sequence: the red Stop light flashes once, then there is a pause where both lights are off. Then the numbers of the recorded fault code flash in amber (Check light). There is a pause between each number. When the number is done, the red light flashes

3-19

again. e.g. red flashes once - pause - amber flashes twice - pause - amber flashes three times - pause - amber flashes five times - pause - red flashes once, indicates fault code 235. If the red light flashes once again, this indicates that there are more active codes recorded. If code 111 is flashed, no faults have been detected. All of the active codes will be displayed first. Once all the active codes have been displayed, the red Stop light will flash twice, indicating the start of the inactive code transmission. These are displayed in the same manner as the active codes. On completion of the inactive code transmission, the red Stop light will flash three times.

Refer to 'Electronic Fuel System Diagnostic Codes' tables for fault code descriptions.

A special diagnostic data reader (DDR) is available that can be plugged into the engine computer memory to extract information related to the cause of the problem. Once the malfunction has been corrected, the Electronic Management System will return the engine to normal operation. The fault code recorded in the ECM memory will remain until it is erased by a technician.

Clearing Fault Codes 1. Depress and the hold the diagnostic request switch.

2. Turn on ignition power (key-on and engine-off).

3. Depress the accelerator pedal 3 times within 10 seconds.

4. The ECM clears all active/inactive fault codes (no affect on Service Indicator).

Reset of Service Indicator 1. Turn ignition key to ON position.

2. Push the diagnostic request switch twice, and then a third time, only now hold the button 3 seconds and release. This entire sequence must be done within 10 seconds.

3-20

The service indicator light triggers at 95% of the normal oil change interval, based on fuel consumption. This is the default value set at the engine factory.

This can be reset with the MPSI reader with the Navistar card. With the reader, it can be programmed on hours or fuel.

Steering Full hydraulic type steering is provided by two single stage, double acting steering cylinders.

To steer the front wheels, rotate the steering wheel in the desired direction to the required radius of turn. The front wheels will turn only as the steering wheel is turned and at a rate of turning directly proportional to steering wheel speed. The front wheels will stop and hold position when the steering wheel is stopped. To return the front wheels to the straight ahead position or to the opposite direction, turn the steering wheel in the opposite direction.

Allow sufficient room when turning, to avoid scuffing the tyres against kerbs or other obstacles. Turn wide enough to avoid other vehicles parked near intersections. If possible, avoid any debris on the road to prevent unnecessary abuse of the tyres.

WARNINGS Improper steering control unit repair or hose connections can cause sudden and forceful steering wheel movement when engine is started.

Keep hands off steering wheel and ensure area around the scraper is clear when starting the engine.

When turning, depress only the tractor accelerator pedal. If both pedals are depressed, the scraper engine will continue to power forward in the original direction, forcing the tractor unit to tilt over.

Steering Wheel Rotation

Transmission This machine is fitted with a Funk DF158 Powershift transmission equipped with the Funk DF158 Electronic Control Unit (ECU), to operate the transmission.

Upshifting and downshifting are the main functions of the ECU. Another function of the ECU is the capability to communicate with a panel mounted gear/ diagnostic display unit.

WARNING Before any welding is done on the machine, disconnect battery cables from terminal posts (ground cables first) and electrical connections at the ECU to avoid damage to electrical components. Turn off the battery master switch before disconnecting any components.

General Theory of Operation The transmissions performance is determined by the various inputs to the ECU. Based upon these inputs the ECU commands the transmission so that maximum performance can be achieved under the present operating conditions. All functions of the ECU are under software control.

Switching the vehicle's ignition to the 'On' position supplies power to the ECU and related system components from the batteries, through the transient voltage protection (TVP) module. At this point the ECU begins to monitor all inputs and outputs. If a known conflict in inputs or a fault condition is detected, the ECU will command the transmission to stay in Neutral regardless of the shift lever position. A flashing error code will be displayed on the gear/diagnostic display unit, and will remain displayed until the error has been corrected and the shift lever cycled back through the Neutral position.

If no error conditions are detected, the ECU will calculate a speed ratio between the engine speed (derived from the engine speed MPU signal) and the transmission output speed (derived from the transmission output speed MPU).

3-33

Based upon this speed ratio and the combination of inputs from the shift lever and any other applicable inputs, the ECU will select the proper transmission gear and command the transmission to shift to this gear. The gear/diagnostic display unit will show the actual gear selected.

The transmission uses electrohydraulic valves to control the operation of the transmission. The solenoids controlling the transmission clutches (solenoids A through D and 1 through 4) are driven by a pulse width modulated (PWM) signal that produces proportional pressure/flow changes. This is achieved by pulsing the solenoid at a constant frequency and varying the 'on time' of each cycle. The ratio of 'on time' to cycle time is called duty cycle. These transmission solenoids are driven with a maximum duty cycle considerably less than this and ramped up to full on. The initial duty cycle is dependant upon several factors and is not a preset value. The process of modulating these clutches greatly enhances shift quality.

3-34

System Components Description and Operation 1. Electronic Control Unit (ECU) - There are two electronic control units located beneath the cab. The ECU is the brain of the system. It is responsible for the logic, computation, and decision making processes and the control of the transmission based on these calculations. How the ECU performs is determined by software programmed into the ECU's memory. The ECUs application is specific, therefore ECUs from different vehicles are not interchangeable.

2. Transient Voltage Protection (TVP) Module - The TVP module is responsible for supplying electrical power to the system and protecting the systems electrical components. It provides 40 volt limiting during an electrical load dump malfunction and protection from reverse battery connection. Protection is provided only while the ignition is switched on, thus energizing an internal relay which provides an electrical connection between vehicle power and the protection device inside the module.

3. Engine Speed Magnetic Pickup (MPU) - The engine speed MPU is located in the input housing of the transmission. The MPU provides a signal to the ECU which represents engine speed. This signal is of a sinusoidal nature, varying in amplitude and frequency relative to engine speed. The ECU conditions this signal and converts it into pulses. It then measures the width of these pulses in microseconds, and based on a preprogrammed value in the ECU which represents the number of pulses per revolution of the engine, calculates the engine speed.

4. Transmission Output Speed MPU - The transmission output speed MPU is located in the rear housing of the transmission and provides a signal to the ECU which represents transmission output speed. This signal is of a sinusoidal nature, varying in amplitude and frequency relative to output speed. The ECU conditions this signal and converts it into pulses. It then measures the width of these pulses in microseconds, and based on a preprogrammed value in the ECU which represents the number of pulses per revolution of the transmission output, calculates output speed.

3-35

5. Gear Shift Lever - The transmission provides seven forward ranges, one reverse gear and a neutral position. The lever is detented in the Forward, Neutral and Reverse positions with a positive lock only in the Neutral position. To move out of the Neutral position, the operator must pull up on the collar.

F N R

The gear shift lever is spring loaded to the centre position. 'Bumping' the shift lever to the upshift or downshift direction sends a corresponding signal to the ECU.

WARNING Do not allow the vehicle to coast in Neutral. This practice can result in severe transmission damage.

When Reverse is selected an audible alarm sounds. This feature warns personnel to the immediate rear of the machine that the operator has shifted the transmission to Reverse.

WARNING Always select Neutral and apply the parking brake before leaving the operator’s seat.

6. Wiring Harness - The wiring harness consists of the various wires needed to provide electrical connections between the components of the system. All connectors in the system are sealed to protect the connections from the environment and to prevent corrosion of the contacts, which would eventually result in a failure.

3-36

1297

7. Gear/Diagnostic Display Unit - A dash mounted gear/diagnostic display unit provides the operator with information about the system. Under normal operating conditions the display shows the actual forward or reverse transmission gear and the state of the disconnect.

When an error has occurred, the display will flash an error code indicating that a problem has been detected in the system. This error code will continue to flash until the shift lever has been placed in Neutral. Once the ECU has detected a legal Neutral condition, the error will clear and 'NEU' will be displayed. Once the shift lever is moved out of Neutral the error will once more begin to flash. This condition will continue until the error has been corrected and the shift lever cycled through Neutral again. If the error is related to the Neutral signal making it impossible for the ECU to see a legal Neutral signal, the error will continue to flash even in the Neutral position until it is resolved.

8. Diagnostic Test Points - The diagnostic test points for the tractor and scraper transmissions are located at the front of the fuse box, under the dash panel.

GENERAL TRANSMISSION OPERATION Watch for wide deviations from normal readings on the transmission oil temperature gauge during machine operation. If the transmission oil temperature gauge shows oil temperature consistently rising above the green zone under normal operating conditions; check for external causes. If none are evident shift to Neutral (N) and operate the engine at 1 200 - 1 500 rev/min. If the transmission oil temperature does not decrease into the green zone within 2 or 3 minutes, the cause of the overheating should be corrected before the machine is operated further. Watch the oil temperature gauge when operating on upgrades, also. If the oil temperature goes into the yellow zone, select the range which will limit upshifts to the highest range in which the transmission will operate closest to the normal temperature range (green zone). If upshifting must be consistently limited to ranges lower than normal for the loads and the grades encountered to prevent overheating the transmission oil, the causes should be determined and corrected.

3-37

Power-Locking Differential (Optional) The power-locking differential allows the operator to increase traction on slippery surfaces where normal differential action between drive wheels is not desirable.

Note: Continued wheel spinning without the Power Locking Differential applied will result in rapid wear of pinion bushings and tyres.

If one wheel spins on a slippery spot with the other wheel on firm footing, decelerate the engine until the spinning wheel stops then depress the power-locking differential pedal. This provides a locking action between the axles, wheels and differentials.

876

Precautions Note: The following precautions should be observed when using the power-locking differential. Failure to adhere to these practices amounts to abuse of the equipment.

1. The power-locking differential may only be used in first gear.

2. Always apply the power-locking differential before engaging in a potential wheel spinning situation (except in a turn).

3. Never apply the power-locking differential while in a turn or when steering is required.

4. Never apply the power-locking differential with one wheel spinning rapidly on a slippery spot. Decelerate the engine until the spinning wheel stops before locking the differential.

5. Never apply the power-locking differential at speeds in excess of maximum speed attainable in first gear and engine at wide open throttle.

For maximum utilisation of the power-locking differential, it is suggested that it be applied when entering the cut and left on until leaving the cut, wherever possible.

Apply power-locking action only as required for added traction to prevent bogging down in soft footing either before starting to move, or when momentum has been lost.

Hydraulic System Controls

1299

Hydraulic System Controls

Located to the right hand side of the operator's seat are three hydraulic control levers. The front lever operates the bowl, centre lever the apron and the rear lever the ejector. Operation of these controls are as follows: 1. Bowl - Pull the control lever to raise the bowl and push to lower. The control lever will return to the 'Neutral' (centralised) position when released. The bowl can also be lowered by pressing bowl drop switch (4), but this should only be used in an emergency, when the bowl cannot be lowered using the bowl control lever.

2. Apron - Pull the control lever to raise the apron and push to lower. The control lever will return to the 'Neutral' (centralised) position when released.

3. Ejector - Pull the control lever to raise the ejector and push to return. A detent will hold the control lever in the return position until travel is complete.

Controlling the bowl, apron and ejector with these levers is simple and easy as the operator is merely moving the valve spools to which they are connected, to direct hydraulic oil to the appropriate cylinders. For maximum cylinder operating efficiency, the engine should be operated at maximum rated speed, and control levers moved to their extreme positions.

Note: Do not use two levers at one time. To do so will cause the component whose control plunger precedes the other in the line to operate, while the other receives no hydraulic pressure. e.g. When unloading, pulling the apron and ejector levers at the same time will allow the ejector to raise while the apron remains down.

3-39

Twin-Hitch Control (Optional) The twin-hitch attachment is optional and permits the operators of two scrapers to assist each other in loading. A bail is attached to the front end of the tractor and a bail to the rear bumper of the scraper. The bail at the front end is raised and lowered by an air operated cylinder controlled by a valve in the operators compartment.

To connect the two scrapers for loading, position the rear tractor twin hitch push plate against the rear bumper of the scraper ahead, with its bail in the 'Raised' position. Be sure that the scrapers are aligned end-to-end in a straight line. Move the bail control lever on the rear scraper to the 'Lower' position and lower the bail over the front scraper bumper hook.

To disconnect the scrapers, move the rear scraper bail control lever to the 'Raise' position. The bail operating cylinders will lift the bail clear of the front scraper hook as soon as any forward pulling force exerted on the bail by the front scraper hook is released.

WARNING Never park or leave a scraper with the bail in the raised position. The bail can be dropped by accidental lever movement or loss of air pressure, which could be dangerous to personnel in the area.

Engine Operation Do not place engine under FULL LOAD at FULL SPEED IMMEDIATELY after starting. ALWAYS allow the engine to fully circulate lubricant and warm up gradually before operating at full speed and full load.

Operate engine at top rated speed when maximum power is needed for the load.

Operation of the engine below top rated speed can occur during gear shifting due to the difference of ratios between transmission gears, but engine operation MUST NOT be sustained more than 30 seconds at full throttle below top rated speed.

Under normal operating conditions, both engines should be accelerated equally to apply equal power to both the tractor and scraper wheels by depressing both engine accelerators at the same time. In a sharp turn however, use only front engine power, because the scraper wheels tend to push the tractor sideways.

NEVER idle the engine more than 5 minutes at a time; shut it off.

If any gauge operates outwith its normal operating range or a warning light illuminates, shut engine down immediately and report to service or maintenance personnel.

WARNING Never start the engine indoors unless proper exhaust ventilation is provided to remove deadly exhaust gases. Once the engine is running, move the machine outdoors as soon as possible. Exhaust gases are hazardous and can cause unconsciousness and death.

Operating the engine beyond high idle speed can cause severe engine damage. The engine speed must not exceed 2 400 rev/min under any circumstances. When descending a steep grade, use a combination of transmission gears, retarder and service brakes to control the vehicle and engine speed.

WARNING Starting fluid is poisonous and flammable. Breathing vapours or repeated contact with skin can cause personal injury. Use only in well ventilated areas. Use with care to avoid fires. Do not smoke when changing cylinders. Do not store cylinders in the operators compartment, living areas, in direct sunlight or at temperatures above 490 C (1020 F). Discard cylinders properly. Do not puncture or burn cylinders. Keep cylinders out of the reach of unauthorized personnel.

Starting the Engine with Jumper Cables WARNING Hazardous hydrogen gas and sulphuric acid. Check for required voltage and polarity connections to discharged batteries. Excessive booster voltage and/or incorrect jumper cable connections, open flame, lighted cigar, or other ignition source can cause battery explosion/fire.

Keep all sources of ignition away from batteries. Do not lean over batteries, and wear eye protection at all times to prevent personal injury.

Do not jump start a vehicle by using arc welding equipment. Currents and voltages are dangerously high and cannot be sufficiently reduced to make the method safe.

Note: Be sure machines are not touching each other. Use cables that are equal to cable size on the machine, for example (1/0) or (2/0).

If jumper cables are used to start an engine, be sure to follow this procedure: Connect one end of a jumper cable, usually coloured red, to the discharged battery 'POSITIVE' (+) post. Connect the other end of the same cable to the 'POSITIVE' (+) post on the booster or charged battery.

Connect one end of the second cable, usually coloured black, to the 'NEGATIVE' (-) post of the booster battery. Connect the other end of the 'NEGATIVE' (-) cable to machine frame for grounding so that if a spark occurs, it is away from battery fumes (explosive hydrogen).

Check for cause of failure on the dead battery.

2. Hydraulic Tank - Hot Oil Level - With the scraper on a level surface, operate the bowl, apron and ejector controls several times to warm the hydraulic oil and fill all hydraulic lines and cylinders. With the bowl on the ground, apron down and ejector returned, shut off the engine and allow thirty seconds for ride cylinders to retract and steering accumulator to discharge oil back to the tank. Check the oil level in the hydraulic tank sight gauge. If oil level is below the 'Cold' level, loosen the filler cap slowly to release any pressure developed in the tank. Remove filler cap and add oil until oil level is between the 'Cold' and 'Hot' marks.

BRAKE FUNCTION CHECKS In addition to the above checks, the following brake function checks can be carried out to determine if both the service and park/emergency brake systems are functional before operating the machine.

4-14

WARNING Make sure the area around the machine is clear of personnel and obstructions before carrying out these checks.

WARNING If the machine moves during these checks, stop the machine, apply the parking brake and do not operate until the fault is corrected.

Note: The following checks are NOT intended to measure maximum brake holding ability. If NEW brake pads are fitted, they MUST be burnished as per the manufacturers recommendations before carrying out the checks.

Service Brake Holding Ability Check With the bowl in the 'Fully Raised' position, depress service brake pedal and select 1st gear on the transmission shift selector. Move the park/emergency control lever to the 'Release' position. Depress front engine accelerator control and accelerate engine to 1 350 rev/min. The machine should not move.

Decelerate the engine, shift transmission to 'Neutral' and apply the park/ emergency brake before releasing the service brake.

Park/Emergency Brake Holding Ability Check With the bowl in the 'Fully Raised' position, move the park/emergency control lever to the 'Park' position and select 1st gear on the transmission shift selector.

Depress front engine accelerator control and accelerate engine to 1 350 rev/min.

The machine should not move. Decelerate the engine, shift transmission to 'Neutral' and move the park/emergency control lever to the 'Park' position.

Note: Brake holding effort required to hold a machine static at a specific engine speed, can vary from machine to machine due to differences in engine performance, powertrain efficiency, etc., as well as differences in brake holding ability.

Note: As an indication of system deterioration, engine speed at which point the machine moved, with the service or park/emergency brakes applied, can be compared against engine speed your machine was able to hold to on a previous check.

Driving and Stopping Before driving off observe all instruments and warning lights. All instruments should operate in their normal range and all warning lights should be out.

Make sure the area around the machine is clear of personnel and obstructions before driving off.

In the first few minutes of travel, check carefully for the required steering, braking, engine and transmission power response for maximum operating safety.

Note: If the scraper is to be parked for an extended period, it is good practice to place planks or timbers under the bowl edges to keep the edges off the ground.

4. Open the drain cocks on all air tanks and leave open so that all condensation will drain completely.

This is especially important in cold weather operation.

5. If below freezing temperatures are expected, make sure the cooling system has sufficient antifreeze to prevent the coolant freezing. If antifreeze cannot be added to the cooling system, drain the cooling system completely.

6. Check all tyres, hoses, wiring, tubing and fittings for cuts, ply separation, abrasion, fraying, or other damage or deterioration. Inspect for structural damage to the cab, body and chassis. Attach warning signs to the steering wheel or to a control to alert others if lubricant has been drained, batteries removed etc..

7. Clean dirt, mud or other matter from steering, bowl, apron and ejector cylinders, particularly from the piston rods. Take care not to damage polished surfaces.

8. Lubricate grease points at the intervals and points specified and with grease specified in Section 8, Lubrication and Servicing, in this handbook.

Note: The above grease points must be lubricated at the proper intervals without fail.

5 - Working The Scraper 5-1

WORKING THE SCRAPER Standard Functions 1. Before entering the cut, raise the apron. Upon entering the cut, lower the scraper bowl until the blades reach the desired depth of cut.

2. When the bowl is filled, lower the apron. Raise the bowl sufficiently to clear the dirt that has accumulated in front of the bowl.

3. Raise the scraper bowl to the desired travelling height and proceed to the fill.

4. At the fill, lower the scraper bowl to the desired depth of fill. Raise the apron no higher than is necessary to clear the load being dumped then use the ejector to finish dumping the load.

Lower the apron, return ejector and raise the scraper bowl to the travel height.

5-2

Loading Self Loading 1. When self loading, apply the power locking differential (if fitted).

2. Raise the apron 300 - 600 mm (1 - 2 ft) above the scraper blades.

3. Lower the scraper bowl until the cut depth is reached.

4. During loading, adjust the apron opening to prevent dirt from piling up in front of the scraper bowl. The opening should be large enough to allow the material to enter the bowl, but not so large as to allow the material to enter and then fall out. The apron opening varies for each type of material being loaded.

1268

5. After the scraper is fully loaded, raise the scraper bowl until the blades are 25 - 50 mm (1 - 2 in) above the ground. Continue to travel out of the cut with the scraper bowl at this height until the dirt that has accumulated in front of the scraper is dispersed.

6. Disengage the power-locking differential (if fitted).

Note: If trouble is encountered in fully closing the apron, the operator will find that moving the apron lever to the lower position shortly before the bowl is completely loaded will allow the dirt flowing into the bowl to push against the apron and close it immediately when the bowl is raised.

1270

Self-Loading Hints When opening a pit, the operator should take the first few cuts to shave the pit, making it as flat as possible so a good working surface is available. At this time also, the cuts should be made to afford good drainage in the right direction.

Subsequent scraper loads can then be obtained in the fastest manner without having to worry about the contour of the pit and drainage problems.

As the operator proceeds through the cut, he will find that inequalities in the surface, over which the machine is moving, and soil conditions make it necessary for the operator to raise and lower the scraper blades to maintain the same depth of cut. The good operator will learn to raise or lower the blade just enough to allow these variations and to maintain a uniform speed.

A common mistake is 'Overcontrol'; that is lifting the blade too high, which allows the machine to move forward at an excessive speed, or dropping the blade too low, which stops the machine completely. Overcontrol may be avoided by using snappy , quickly repeated movements of the scraper bowl control lever. This brings the blade to the proper level necessary without overcontrol and causing the surface being cut to become rough or scalloped.

5-4

Push-Loading BACKTRACK LOADING

When push-loading hard, rocky or frozen material, apply only enough power to front scraper tractor to operate the hydraulic system.

CHAIN LOADING

724

Push-loading a scraper with a crawler tractor is recommended for loading most materials, because of the extra traction of a crawler tractor.

SHUTTLE LOADING

Backtrack loading is usually used where the cut is fairly short and it is impractical to load both ways. Chain loading is usually used where the cut is fairly long, making it possible to pick up two or more scraper loads without backtracking.

Shuttle loading is usually used for short cuts where it is practical to load both ways. In many cases a combination of any two of the above can be used to great advantage for increasing production.

Push-Loading Hints 1. Eliminate lost time by keeping pusher tractor at a minimum. To do this, the scraper should pull alongside the pusher tractor when it is loading another machine so the scraper will be readily available when it is its turn to load.

725

2. Use fast loading methods. A good example of this is step loading in wide cuts.

To step load, a cut is taken on both sides of a scraper wide strip leaving a step in the middle where a third machine can be loaded quickly.

3. Use proper blade combinations for the type of cut and soil.

4. Always load and unload DOWNHILL where possible. This greatly reduces the amount of tractive power required.

5. Eliminate all unnecessary turns. When working a job with a cut on each side of the fill, the figure 8 loading and hauling cycle can be used to great advantage.

This cycle eliminates one turn per load.

726

6. When working on a job with a series of cuts and fills, the 'S' layout can be used to great advantage in eliminating turns. In using either method, remember to always cut on the DOWNHILL travel.

5-5

Hauling After the machine is fully loaded and has reached the haul road, the operator should raise the bowl to the travel height and proceed to the fill or dumping area in the highest gear range practicable. The bowl travel height should be no higher than necessary to clear any obstacles that might be on the haul road. A low bowl height permits the operator better control of the machine by keeping its centre of gravity low and prevents the loss of time necessary to lower the bowl as the machine approaches the fill area. The best bowl travel height, if possible, is the height at which the bowl must be when the load is spread.

716

When travelling over a slippery haul road, keep the blades as close to the road as possible. Doing this allows the operator to drop the bowl and help stop the machine in case of an emergency. Shift to first gear and engage the power locking differential (if fitted) as required to maintain good traction enroute, unless steering is required. Do not engage at speed in excess of speed attainable in first gear and engine at wide open throttle. While travelling over the haul road, avoid holes and large obstacles which may damage the machine's tyres. When making a sharp turn, do not cut the corner too close but allow for the scraper length so as not to pull the scraper wheels off the road.

876

5-6

Watch Bowl Height

Spreading 1. On approaching the fill area, the operator should lower or raise the scraper bowl to the depth of fill desired. The speed of the machine must also be adjusted to this depth - a relatively high speed for a thin spread, or a slower speed for a deep spread.

717

Adjust Speed and Bowl Height

1

To start spreading, raise the apron by pulling the apron control lever to allow the dirt to fall out of the bowl. The size of the apron opening depends on two factors; the depth of the spread and the type of material being spread. A thin layer of free-flowing material, such as sand, will require only a small apron opening and high machine speed, while a larger opening and slower machine speed will be necessary for a thin spread of gummy material, such as wet clay.

2. After the apron opening has been adjusted, the ejector must be activated to finish unloading the scraper bowl when the dirt flow through the apron opening lessens. To permit an even spread, activate the ejector immediately when the dirt flow lessens.

728

Apron and Ejector Actions

5. Lower the apron and place the control lever in 'Neutral'.

Spreading Hints 1. Keep the machine moving while unloading. Stopping during the unloading operation on a soft fill will cost production time by needless shifting and possible bogging down of the machine. Apply the power locking differential as needed on the fill.

2. Always make an even spread so the next trip will not be rough.

5-8

3. If possible when travelling out of a fill, pass back over the area you have just filled in order to compact it with the large tyres.

RETURNING TO THE CUT While returning to the cut, it is good practice to occasionally grade the haul road with the scraper blade. By watching the road, the operator can vary the cutting action of the blades to cut off small rises and carry the dirt to depressions while travelling.

When returning to the cut and not grading the haul road, carry the scraper bowl high enough to avoid any haul road obstacles, yet low enough for good handling.

Carrying the bowl low will allow quick slowing of the machine by lowering the cutting edge to the ground if necessary. Allow plenty of room for the scraper wheels to avoid obstacles when making tight turns, and maintain a safe speed for the condition of the haul road.

WORKING SPECIAL MATERIALS Sand

730

Sand Buildup Ahead of Bowl

Sand, being a free-flowing material, has a tendency to float ahead of the scraper blade when being loaded. To load the scraper completely and to avoid being bogged down by the sand, it is necessary to 'Pump Load'. To do this, enter the cut in the usual manner with the apron open approximately 1 m (3 ft) and the scraper blade lowered into the ground. Continue through the cut until the bowl is approximately half-full or the machine starts to stall.

When this happens, lower the apron into the sand that has piled up in front of the scraper blade and raise the bowl 50 - 75 mm (2 - 3 in). Continue through the cut alternately dropping and raising the bowl 75 - 100 mm (3 - 4 in) at a time. Do not completely close the apron or drop the bowl deep enough to stall the machine.

This 'Pump Loading' will ordinarily allow the scraper to obtain a full load.

731

Lower Apron and Raise Bowl

When spreading sand, always spread it as thin as possible and keep the machine moving in the fill. A thin spread will allow better compaction and will make travelling over the fill easier. In many cases, reduced tyre pressures will greatly aid the loading and spreading operations in loose sand.

5-9

Coal Coal stockpiling with a scraper accomplishes two things; it compacts the coal with the tyres, and it affords a fast and efficient method of handling coal when it must be moved around the stockpile.

Loose coal is loaded from the stockpile with a smooth cut, to avoid drainage problems. Care should be taken not to drop the bowl too deep as this will stall the machine. Spread a load of coal in thin equal layers of approximately 150 mm (6 in) thick. After spreading, travel back over the freshly spread coal if possible, to allow the tyres to compact the coal. This is important as it eliminates air holes, lessening the chances of spontaneous combustion.

732

Spreading Coal

733

Back Up to Release Stones

734

Bowl High/Apron Open Wide

Gravel To obtain a complete load when loading gravel, it may be necessary to 'Pump Load' it in the same manner as previously described for sand. Some difficulty may be experienced in closing the apron due to large stones being caught between it and the scraper blade. To overcome this, back up slightly with the blade still in the ground while closing the apron. This will ordinarily force the stones out and allow the apron to close completely.

To prolong tyre life, avoid spinning the wheels and hitting sharp rocks. The tyres should be kept at the proper inflation pressure as recommended by your local tyre dealer for the particular machine and tyres involved.

Wet and Sticky Material The greatest difficulty with handling these particular materials is during the unloading process. This may be overcome by using a few precautions.

When unloading, do not attempt to spread the material too thin and always keep the bowl high enough to allow the material to flow back under the scraper.

5-10

Attempting to spread the material too thin and/or keeping the bowl too low will cause the material to pack against the scraper blade and inside the bowl, making it impossible to eject the load.

If the material is so sticky that it will not flow out of the bowl, bring the ejector forward, and alternately power-down and raise the apron, slicing off sections of the material.

Loading Large Objects 735

Power Down Apron

Proper manoeuvring of the machine will enable the scraper to pick up large objects that the tractor can not pass over.

Approach the object with the apron and scraper bowl raised to their full heights.

Bring the tractor past the object until the drive wheels are slightly beyond it.

Pivot the tractor sharply towards the object. This will enable the tractor to bypass the object and bring the scraper blade into position to load it.

736

Approaching the Object

When the tractor reaches its sharpest angle of turn, bring the scraper blade close to the object. Lower the scraper blade and load in the usual manner. To completely close the apron after the object has been loaded, a little dirt may have to be picked up to push it back into the scraper bowl.

To unload the object, it may be necessary to extend and return the ejector a few times to move it around so it will fall out. If necessary, more dirt can be loaded to position the object for unloading. After the object has been unloaded, turn the machine sharply so that the scraper may go around it.

737

Pivoting the Tractor

5-11

BLADE ARRANGEMENTS The scraper cutting edges (blades) and scraper blade base are designed so that one type of edge can be used for various edge arrangements. In addition, the edges are reversible which prolongs the useful life of the edges. The use of the proper edge arrangement for certain types of cut or soil conditions can save a great deal of money in edge replacement and labour. Scraper edges should never be allowed to wear to the point where the blade base is doing the cutting.

The 100 mm (4 in) drop centre arrangement is recommended for hard, rock-free soils when a maximum drop centre and centre heaped loads is required. To renew this arrangement after one edge is worn, reverse all edges and interchange the outer pair of edges with the inner pair.

The straight edge arrangement is recommended whenever a level cut or a level fill is required. To renew this arrangement after one edge is worn, reverse all edges and interchange the outer pair of edges with the inner pair.

100 mm (4 in)

738

DIRECTION OF CUT

739

The maximum overhang arrangement is recommended for fast, easy loading in rock-free soils and for maximum edge wear life. When working in rocky soils, the minimum overhang edge arrangement is recommended. For beginning scraper cuts on side slopes or to crown a scraper cut, the one side cutting edge is recommended. These three edge arrangements cannot be renewed by reversing the edge when one edge is worn, however, the edges can be used with the 100 mm (4 in) drop centre and straight edge arrangements.

TWIN HITCH LOADING (Optional Attachment) TRACTOR

SCRAPER

Twin Hitch loading uses two scrapers hooked together, end to end, to assist each other in the loading operation.

Two scrapers enter the cut aligned bumper to bumper. The front scraper begins its cut in first gear and the drag created by the cutting action of the blade slows the scraper allowing the rear scraper to catch up. The rear scraper, with bail raised, contacts the front scraper's rear bumper. Cushions mounted behind the push plate on the rear scraper absorb the shock of impact and make the contact smoother.

741

TRACTOR

SCRAPER

Note: When using the Twin Hitch, use scrapers of the same size and equipped with the same size of tyres. Using scrapers of different sizes can cause excessive stresses within each machine which can result in reduced life.

As the rear scraper begins to push the front scraper, the rear scraper operator shifts the bail control lever to the 'Lower' position. This lowers the bail over the rear bumper hook of the front scraper and positions it for the remaining operation.

742

TRACTOR

SCRAPER

The rear scraper continues pushing the front scraper until it is filled. At this point, usually on a signal from the operator of the rear scraper, the bowl of the first scraper is raised. The rear scraper should continue pushing until the front scraper's bowl is raised and it can accelerate and pull away from the rear scraper. The hook of the front scraper then catches in the bail of the rear scraper. When the operator of the rear scraper feels the front scraper pulling, the rear scraper bowl is lowered and the cut is continued.

While the front scraper is pulling, the operator of the rear scraper shifts the bail control lever to the 'Raise' position, but the two scrapers will remain together as long as the front scraper continues pulling.

743

Note: When scrapers are hooked together they must remain in a straight line,

5-13

as turning of either scraper will damage the bail of the rear scraper. If for any reason the front scraper should become turned at an angle to the rear scraper while pulling, the operator of the front scraper should decrease pulling power and correct the angle.

TRACTOR

When the rear scraper is full, the operator raises the bowl slightly off cut, shifts to second gear range and accelerates, overtaking the front scraper. As the rear scraper accelerates and overtakes the front scraper, the pulling force of the front scraper on the bail of the rear scraper is released, allowing the bail to raise.

When the operator of the front scraper feels the bump of the rear scraper, the operator knows that the rear scraper is full and it all right to shift to a higher gear range and pull away. As the machines proceed to the dump area, the rear scraper should steer away from the front scraper before beginning to turn to avoid damaging the front scraper.

744

Note: When hauling, lower the bowl as much as possible to raise the nose of the tractor and increase ground clearance of the hitch.

Scraper teams with Twin Hitches should alternate pushing and pulling operations as much as possible to equalize wear of attachments on both machines. It is also recommended that the front portion of the Twin Hitch attachments be removed from the scrapers when operations will not involve the use of Twin Hitch, thus reducing the chance of accidental damage to the attachments.

WARNING Never park or leave a scraper with the bail in the raised position. The bail can be dropped by accidental movement or loss of air pressure, which could be dangerous to personnel in the area.

5-14

745

SCRAPER

TYPES OF CUTS Cutting Through Hills To cut out the centre of a hill, the first cut should be taken at stakes 'A'. Work across the hill taking cuts until stakes 'B' are reached. The next cut should be taken one scraper width from the first cut, forming a step. Take cuts across the hill until one scraper width from Stakes 'B' is reached.

746

Cutting Through Hills

This will form a step at stakes 'B' side of the hill. All cuts should be made with the centre of the cut higher than both ends of the cut. Repeat this procedure until the required depth is reached. The steps can be smoothed out with a grader if the slope is gentle, or a crawler if the slope is steep.

STAKE

Cutting Banks When cutting down a bank, the first cut should be made at the stakes and then cuts should be made as shown by the numbered sequence shown in the illustration. This method will keep the scraper level, or leaning toward the bank, and prevent the possibility of the scraper slipping down the bank. A grader or crawler can then smooth out the bank slope after the cuts have been made.

747

Cutting Banks

Stripping Topsoil The cuts should proceed across the cutting area, using the step method of loading. To step load, a cut is taken on both sides of a scraper wide strip leaving a step in the middle where a third cut can be quickly loaded.

748

Stripping Topsoil

5-15

Starting A Ditch To start a ditch, take several cuts along the ditch grade stakes until the cut is deep enough to allow the scraper cutting edge to approximate the slope required. Place one set of wheels in the cut, the other on the bank and cut the ditch at the required angle. To finish the ditch, use a scraper equipped with a straight cutting edge arrangement.

749

Starting Ditch

750

Starting Fill

751

Building Fill

TYPES OF FILLS To start a fill, spread the first loads a few feet away from the fill and grade stakes. This practice compensates for the dirt being pushed out by the scraper and tractor wheels as the fill deepens. If the first loads are spread in line with the stakes, the machine's wheels will push the dirt beyond these stakes resulting in unnecessary bulldozing work to clean up the fill.

When building a fill, the outside edges or shoulders should be kept higher than the centre. This allows the scraper to spread close to the edge without danger of sliding over it. The fill slope can be built at the proper angle, reducing the bulldozer work required to back-finish it.

5-16

Spread equal layers at the fill site, keeping the centre lower than the sides.

When the shoulders reach grade level, it is very easy to finish the fill by filling the centre. At the end of the work day or when the fill is to be left for a time, always fill in the centre for better drainage.

752

Spread Equal Layers

Where the fill must meet specific compactation requirements, the load must be spread in thin, equal thicknesses, or 'Lifts'. To accomplish this, set the bowl to give the desired lift before entering the fill. As the load is spread, the scraper wheels pull up on the freshly spread material and raise the height of the bowl from the ground. To compensate for this, lower the bowl to maintain the same lift. If the bowl is not lowered, the spread will be much thicker at the end than it was at the beginning.

753

Allow for Lift

FINISHING AND GRADING The scraper can be used to finish level ground and moderate slopes, by using a straight edge blade arrangement. If it is necessary to carry dirt from one spot to another, load in the usual manner; however, for grading work, carry the apron high and ejector forward to produce the same effect as a bulldozer/grader blade.

754

Grading Arrangement

When finishing a slope, DO NOT attempt to load as the dirt will fall to the lower side of the bowl, resulting in this side cutting deeper than the high side. Always keep tyres at the same inflation pressure. A low tyre pressure on one side will cause the blade to cut deeper on that side.

5-17

5-18

6 - Roading 6-1

ROADING WARNING These machines are equipped with cylinders containing compressed nitrogen gas. Transportation of these machines by any method may require a special permit from the appropriate authority of the country involved. Consult your Dealer for details.

General 'Roading' (operating a scraper over public highways) requires special care and attention. Scrapers, because of their large size, are slower and less manoeuvrable than most other machines encountered on the road. Yet, while on the road, they must be operated for extended periods of time at, or near, maximum speeds.

Before 'Roading' a scraper for an extended distance between jobs, or between widely scattered sections of a job, the machine must be properly equipped and in good condition. It is also recommended to carry a 'Warning Triangle'.

The operator must use extra care while on the public highways and remain constantly alert, especially for overhead cables and low bridges.

Necessary permits must be obtained from the proper authorities before the machine is 'Roaded' on public highways.

Preparation Prior to Roading Lubrication Thoroughly lubricate and service all components and systems as described under 'LUBRICATION AND SERVICING' in this handbook and/or Service Manuals for this machine.

6-2

Inspection Perform all pre-starting and post-starting checks described in this Handbook.

Pay particular attention to the function of all instruments and lights, and make any repairs necessary.

Note: Improper tyre inflation during over-the-road operation can cause rapid tyre deterioration by overheating. Tyre pressures increase with heat. Always check pressures while tyre is cold. Consult your tyre dealer for proper pressures and tyre speed limits for roading.

Check the inflation pressures of all tyres, while cold, with an accurate tyre pressure gauge. Inflate tyres if necessary, while cold, to the recommended pressure for 'Roading'. Inspect all tyres thoroughly and carefully for stones or other debris embedded in the treads or carcasses. Inspect for cuts, bruises, burned beads abnormal wear and damaged wheels rims. Replace any damaged or excessively worn tyres.

Check all hoses, drain cocks, fuel level check cocks, and other potential sources of air or fluid leaks. Make sure that all leaks are repaired and that all drain cocks are sufficiently tightened to avoid subsequent loosening. Make sure that all warning flags, oversize load signs etc. are in place and secure.

Clean all glass and adjust the seat for proper operation of all controls.

Check the lights, horn, windscreen wipers, heater, defroster, headlight dip control, and all controls for proper operation.

Make sure the scraper bowl is empty and in a fully raised position and the ejector fully retracted. Make sure the apron is lowered completely.

Remove the planetary flange covers from the scraper wheels, pull out the axle shafts and reinstall the gaskets and planetary flange covers to keep dust and dirt out of the planetary gears and gear oil in.

Make sure all hydraulic control levers are in the 'Hold' position.

6-3

In Case of Trouble If trouble develops enroute, move machine off the road at the first safe parking place, and shut off the engine. Carefully note as many of the symptoms of the trouble as possible, such as rough engine operation with loss of power and overheating, or loss of speed and transmission clutch pressure with normal engine operation etc..

If the area in which the trouble occurs requires that the machine be left unattended while the trouble is reported by phone, disconnect a battery cable and apply security locks, if so equipped, before leaving the parked machine.

Make sure bowl is completely lowered, if it has not been blocked up in the travel position, and the parking brake is applied.

Report the following data as soon as possible: 1. Exact location.

2. Destination.

3. The nature of the trouble (with as many details as possible) and the time and conditions under which it happened.

4. The telephone number at which the machine operator can be reached.

Note: Do not attempt to restart or operate the machine unless instructed to do so. An engine, pump, transmission or other component that develops a minor defect can be completely destroyed in just a few extra minutes of unnecessary operation.

6-4

7 - Moving Disabled Scraper 7-1

MOVING DISABLED SCRAPER Any unusual powertrain noises noted while operating the scraper should be reported to those responsible for maintenance. Should the powertrain, air, hydraulic or electrical systems fail, the machine should be stopped and shut down immediately until suitable repairs can be made. If the failure is in the powertrain and the scraper must be moved to a service area or workshop to make required repairs, remove the planetary flange covers from the tractor and scraper wheels and pull out the axle shafts. This will prevent any possible additional damage which may be caused by the drive wheels turning the powertrain as the machine is towed. Replace the covers on the drive wheels to retain lubricant and prevent entry of dirt.

If possible, start the engine to provide the required air and hydraulic pressure for steering and braking. Never allow riders on a machine being towed without sufficient hydraulic pressure for safe steering and braking.

If the nature of the trouble prevents engine operation, repairs must be made on the site of the breakdown, or special arrangements made for towing the machine safely to the repair area without braking and steering power.

WARNING Uncontrolled machine movement hazard. There is no mechanical connection between the machine wheels and the engine when the parking brake is released. Before releasing the parking brake, make sure the machine wheels are secured with chock blocks to prevent or restrict unexpected machine movement. When moving the machine with insufficient air and hydraulic pressure, for safe braking and steering, use extreme caution to ensure personnel and property safety.

If the safety or parking brake has been applied and the engine cannot be started, the air tanks must be recharged by an external source to release the brakes before the scraper can be moved.

WARNING When using a chain or cable, be sure it is strong enough for the expected load and properly secured.

When pulling, take up the slack slowly to avoid jerking. A chain or cable which fails under load can cause serious injury. Stand clear. Do not pull through a kinked chain or cable. Do not pull or tow unless the operator's compartment is guarded against, or out of reach of, a whipping chain or cable. Attach only to the towing hook. Failure to follow these instructions could cause serious injury or death.

Always attach a 'DO NOT OPERATE' or similar warning sign to ignition switch or a control before cleaning, lubricating or servicing the machine.

8-2

LUBRICATION AND SERVICING Lubrication is an essential part of preventive maintenance. It is important that the instructions regarding types of lubricants and the frequency of their application be followed to prolong the useful life of the machine. Periodic lubrication of moving parts reduces to a minimum the possibility of mechanical failures.

Thoroughly clean all fittings, caps, plugs etc., to prevent dirt from entering the system while servicing.

Lubricants must be at operating temperature when draining.

Do not operate any system unless oil level is within the operating range as indicated on oil level dip stick, sight gauge or level plug.

Small circles on the following illustrations represent points at which lubrication or servicing must take place, at the intervals indicated on the left-hand side of the lubrication chart.

The numbered circles on the illustrations contain reference numbers which correspond to the 'Ref. Points' column of the chart.

All change and service periods are recommendations based on average operating conditions. Lubricants showing evidence of excessive heat, oxidation or dirt should be changed more frequently to prevent these conditions. Lubricant change and service periods must be established on the basis of individual job conditions.
