d. Replace all parts that have damage or wear.

 Never operate the machine under the influence of alcohol, drugs or while otherwise impaired.  Never permit anyone other than the machine operator to ride on the machine.  A person or pet within the operating area of a machine can be struck or crushed by the machine or its equipment. DO NOT allow anyone to enter the work area.  Any person who operates the machine or performs machine maintenance or repairs must be familiar with the guidelines given in this Operator’s Manual.

e. Replace belts that have cuts that can make the belt weak. f. Check that bolts on the seat bracket or mounting are tight. g. If the belt is attached to the seat, make sure the seat or seat brackets are mounted securely. h. Keep seat belts clean and dry. i. Clean belts with soap solution and warm water only. j. Do not use bleach or dye on the belts because this can make the belts weak.

 Keep clear of moving parts. Loose clothing, jewelry, watches, long hair and other loose or hanging items can become entangled in moving parts.  Always use personal protective equipment (PPE), such as work clothing, safety boots, hard hat and hearing protection.  Make sure all guards and shields are in good condition and properly installed before operating the machine. Never operate the machine with the shields or guards removed.  Make sure all components are in good condition and tighten all connections before starting the engine or pressurizing the system.  Dirty or slippery steps, ladders, handholds, walkways and platforms can cause falls. Make sure these surfaces remain clean and clear of debris.  Operate machine controls only when seated in the operator seat.  Before starting the machine, be sure that the drive controls are in their neutral position.  DO NOT attempt to remove material from any part of the machine while it is being operated or components are in motion.  Never smoke or handle open flames when checking or pumping fuels, refilling oils, lubricating the machine or inspecting or pressurizing the accumulator.  Seat belt inspection and maintenance: a. Keep seat belts in good condition. b. Keep the belts away from sharp edges and items that could cause damage. c. Periodically check belts, buckles, retractors, tethers, slack take-up system and mounting bolts for damage.

SECTION 00 – MAINTENANCE – CHAPTER 2 2.1.4. General operating safety Before starting work, the operator must do the following:  Be familiar with the work site environment, i.e. with the slopes, utility line system, as well as with necessary types of work site protections.  Indicate each machine start-up with an acoustic or light signal and allow a few moments for personnel to leave the work area before turning on the machine engine.  Confirm brake and steering functionality before operating the machine.  Always make sure the work area is clear of tools, parts, other persons and pets before you start operating the machine.  Always keep windows, mirrors, all lighting and the Slow Moving Vehicle (SMV) emblem clean to provide the best possible visibility while operating the machine.  Never operate the machine in enclosed spaces as harmful exhaust gases may build up.  DO NOT operate the machine during an electrical storm.

-

-

If lightning should strike during operation, remain in the cab. Do not leave the cab or operator’s platform. Do not make contact with the ground or objects outside the machine.

If you are on the ground during an electrical storm, stay away from machinery and equipment. Seek shelter in a permanent, protected structure.

 DO NOT operate the machine when within hazardous reach of other machines or transportation means aside from those that operate in mutual concert with the machine.  DO NOT operate the machine at places impossible to see from the operator platform and where hazard to people or property could occur unless work safety has been secured through some other way, such as via signaling by duly instructed personnel.  DO NOT operate the machine under reduced visibility or at night, unless the machine’s work area and the work site are illuminated sufficiently.  Pay attention to overhead power lines and hanging obstacles. High voltage lines may require significant clearance for safety. If the machine comes into contact with high voltage, observe the following principles: -

do not attempt to leave the operator platform while in the hazardous zone

-

warn others to keep off and not touch the machine

-

try to drive the machine out of the hazardous zone

 When parking the machine on a road, always take into consideration the effect the weight of the machine will have on the road.  Exposure to loud noises could cause hearing damage. Always wear hearing protection when operating noisy equipment or when working in a noisy environment.

 Before leaving the machine: a. Park the machine on a firm, level surface. b. Put the drive controls in their neutral position. c. Turn off the engine and remove the key.  Start the engine from the operator seat only.  DO NOT roll and compact at slopes of such angles where there is a risk of soil breaking off (dropping) under the machine or a risk of loss of grip followed by uncontrolled slip.  Depending on the bearing capacity of the subsoil, DO NOT roll and compact at such a distance from the edge of the slope or trench that there is a risk of landslide or the shoulder breaking off (dropping) together with the machine.  DO NOT roll and compact with vibration at such a distance from walls, cuts or slopes that would cause them to slip (slide) and cover the machine.  DO NOT compact with vibration at such a distance from buildings or facilities and equipment that there is a risk of them being damaged due to vibration transfer impact.

Performance classification under AMERICAN PETROLEUM INSTITUTE (API)

The ambient temperature and type of operations at the site of machine use are decisive in determining the SOCIETY OF AUTOMOTIVE ENGINEERS (SAE) viscosity class.

Recommended oils:

15W-40

Viscosity classification

SAE 10W30: Winter SAE 5W30: Arctic API CI-4 oil is recommended Year-round: SAE 15W-40, refer to the viscosity diagram.

•

Exceeding the low temperature limit will not cause engine damage, but may cause some starting difficulties.

•

It is convenient to use universal multi-range oils to avoid the need to change oil due to ambient temperature.

•

It is possible to use a synthetic engine oil if the performance and viscosity classifications of the oil correspond to the recommended mineral oils.

•

The oil change intervals used must be the same as those for mineral oils.

•

To make starting at temperatures below 0°C (32°F) easier, the engine manufacturer recommends SAE 10W-30 oil.

5W-30

SAE 15W40: All seasons

10W-30

Case Akcela No. 1, 15W-40 Engine Oil:

400150

NOTICE Do not exceed the upper temperature limit for a prolonged period of time as this will reduce the capabilities of the oil.

When using oil API CG-4/SH, the oil change interval must be reduced by half, i.e. 125 hours.

DV207 / DV207HF

SECTION 00 – MAINTENANCE – CHAPTER 6 6.2.2. Fuel

WARNING Never mix diesel with gasoline or alcohol.

These mixtures may cause an explosion!

Failure to comply could result in death or serious injury.

Use fuel that complies with the ASTM (American Society for Testing and Materials) D975 standard: Grade no. 2 fuel

•

Fuel viscosity must be over 1.3 cST at 40°C (104°F) to ensure proper liquidity characteristics and proper lubrication of fuel system components.

NOTICE Check with your fuel supplier for the correct cold weather fuel.

General specification - biodiesel fuel Fatty Acid Methyl Ester (FAME) biodiesel, referred to as biodiesel fuel in the following section, is a family of fuels derived from vegetable oils treated with methyl esters.

NOTICE Biodiesel fuel blends are approved for your engine only if they comply with EN14214 specification standards or ASTM D6751.

NOTICE It is imperative that you check with your CASE dealer to find out which blend is approved for your engine. Be aware that use of biodiesel fuel that does not comply with the standards mentioned above could lead to severe damage to the engine and fuel system of your machine. The use of fuels that are not approved may void CASE warranty coverage.

Biodiesel fuel usage conditions

NOTICE The biodiesel fuel must comply with the fuel specification indicated above.

Biodiesel fuel must be purchased from a trusted supplier that understands the product and maintains good fuel quality. Biodiesel fuel must be preblended by the supplier. Mixing biodiesel fuels on-site could result in an incorrect mixture that could lead to problems with both the engine and the fuel system.

6-4

Engine performance is affected by the use of biodiesel fuel. There may be up to 12% reduction in power or torque depending on the blend used.

NOTICE DO NOT modify the engine and/or injection pump settings to recover the reduced performance.

The reduced power must be accepted if using any biodiesel fuel blend.

Some modification may be required to allow your engine to run on biodiesel fuel. Consult your dealer for complete information on these modifications.

Biodiesel fuel has a higher cloud point than diesel fuel.

NOTICE The use of high biodiesel fuel blends are not recommended in cold weather conditions.

With biodiesel fuels, it may be necessary to change the engine oil, engine oil filter and fuel filter elements more frequently than with diesel fuels. Biodiesel fuel can remove rust and particles from the inside of onsite fuel storage tanks that would normally adhere to the sides of the tank. Like particle deposits that commonly occur with diesel fuel, these particles can become trapped by the machine fuel filters, causing blockage and shortening filter life. This is more likely to happen in cold weather. Consult your CASE dealer for information on cold weather operation and proper maintenance intervals when using any biodiesel fuel blend.

When handling biodiesel fuel, be careful not to introduce water into the fuel supply. Biodiesel fuel attracts moisture from the atmosphere.

Keep fuel tanks as full as possible to limit the amount of air and water vapor. It may be necessary to drain the fuel filter water trap more frequently.

Potential oxidation and stability could be a problem with the fuel stored in the machine.

NOTICE Machines must not be stored for more than 3 months with biodiesel fuel blends in the fuel system.

If longer storage periods are necessary, the engine must run on pure diesel fuel for a minimum of 20 hours to flush the biodiesel fuel out of the fuel system prior to storage.

DV207 / DV207HF

SERVICE MANUAL 6.2.4. Hydraulic oil

NOTICE Biodiesel fuel must not be stored in on-site storage tanks for more than three months.

Any spillage of biodiesel fuel must be cleaned up immediately before it can cause damage to the environment and the paint finish of the machine.

Before using biodiesel fuel blends, consult your dealer to receive full information about the blend approved for your machine and any detailed conditions of its usage.

2158

Use only the following quality hydraulic oil of the correct performance class for the machine’s hydraulic system: Case Akcela Hy-Tran Ultra Synthetic hydraulic oil It is possible to fill the hydraulic system with synthetic oil for which any leakage will be completely biodegraded via microorganisms found in water and soil.

NOTICE Be aware that not fulfilling the requirements and conditions of biodiesel fuel usage will void your machine’s CASE warranty coverage.

NOTICE Always consult with the oil manufacturer or dealer before switching from mineral oil to synthetic oil or mixing oils of different brands!

6.2.5. Lube grease

6.2.3. Coolant

0787

2152

WARNING Hazardous nitroamines will form when a nitride-based antifreeze is mixed with an amine-based agent. Failure to comply could result in death or serious injury.

Use antifreeze in all seasons to protect the cooling system from corrosion and all risk of freezing.

For areas where ambient temperature is over -36°C (-32.8°F), use a blend of 50% ethylene-glycol based antifreeze.

For areas where the temperature is below -36°C (-32.8°F), it is advisable to use a blend of 40% water and 60% antifreeze.

NOTICE Do NOT use coolant with an antifreeze concentration greater than 50% (point of congelation is -36°C [-34°F], boiling point is 110°C [228°F]) unless absolutely required.

NEVER use an antifreeze concentration over 68%!

We do NOT recommend the blending of antifreeze agents. Blending various types of coolant may cause loss of anticorrosion properties.

Always check the antifreeze concentration of the coolant with a refractometer before the winter season starts.

DV207 / DV207HF

Use plastic lubricant with lithium content to lubricate the machine: CASE Akcela Extreme pressure grease moly

6.2.6. Washer fluid 2260

Use water (up to 0°C [32°F]) and motor vehicle glass washer fluid when filling the washer fluid reservoir.

NOTICE Fill with a winter-rated motor vehicle glass washer fluid when temperatures are below 0°C (32°F).

6.2.7. Gear oil 2186

Use high-quality fluid corresponding to Case Akcela 135H EP Gear Lube 80W-90 to lubricate the transmissions, pumps and drum reducers.

Use extreme pressure type fluid API-GL5 category SAE 80W-90 EP for outdoor temperature range -10°C-35°C (14°F-95°F).

SECTION 35 – HYDRAULIC SYSTEM – CHAPTER 11 11.4. Adjusting vibration frequency To adjust vibration, check and, if necessary, adjust max. engine rpm. (refer to “8. Removing the engine”).

Check frequency values with the roller at standstill and placed on a test bench, or on tires laid down or on a soft surface at max engine speed (adjusted to 2100/2200). Position the gauge probe on the drum mantle and turn vibration ON at the measured drum only.

401D275

NOTICE The maximum total vibrator run time with no drum rotation (to lubricate bearings) is 2 minutes!!!

Or position the gauge probe on the damper plate.

When measuring this way, you can scan vibrator frequency while driving the machine.

401D276 Use Allen screws to adjust vibrator frequency (1) (low amplitude) and (2) (high amplitude) with the locking nut loosened.

Loosening (turning counterclockwise) increases frequency and vice versa. Start the engine and check the set value again with the engine running.

SECTION 55 – ELECTRICAL SYSTEM – CHAPTER 17 17.2. Storage battery

Maintenance during operation

The maintenance-free storage battery is located in the rear frame of the machine.

A properly functioning charging system will keep the storage battery almost fully charged. The regulated voltage level moves within 13 - 14 V limits.

Charging

Recharge the battery with current from 0.1 of its total capacity up until the fully charged indicator comes on.

Measure the no-load voltage of the battery with a digital multimeter.

Data for checking the charge 100% charge means no-load voltage is over 12.6 V 70% charge means voltage is 12.40-12.54 V 50% charge means voltage is 12.24-12.40 V Deep discharge is below 12.18 V It is normal to charge a new storage battery via software-controlled charger according to IU, IUIA characteristics.

Indication of charge 100% charged storage battery (measured at current flow required) -

Voltage will reach its max. level. During charging, voltage will not change for the period of 2 hours.

The best conditions for battery operation and storage are frequent discharging and recharging along with 100% condition. Maintain the batteries at

Keep storage batteries clean and well secured. Make sure the fixing device does not deform the storage battery block. Battery terminals must be properly tightened.

Aerosol of electrolyte forms sulfates on the surface of terminals’ metal parts. Clean up these sulfates. Protect cleaned metal parts with a thin layer of preservation vaseline or oil.

NOTICE Handle the storage batteries and electrolyte with adequate care. Wear gloves and safety glasses (face shield).

If skin comes into contact with electrolyte, flush immediately with water; use soap or baking soda to neutralize. When charging, oxygen and hydrogen are released from the electrolyte on the electrodes, forming and explosive mixture. It is therefore strictly forbidden to perform hot work in the vicinity of the storage battery. Even a spark generated when disconnecting or loosening a terminal with the charging circuit energized could cause an explosion.

When removing, disconnect the negative (–) pole cable first and then the positive (+) one.

NEVER disconnect the storage battery with the engine running.

When operating and handling storage batteries, always follow the safety procedures, recommendations and warning provided by the battery manufacturer.

SERVICE MANUAL 17.3. Alternator

Informative inspection of alternator on the machine

The alternator is used as an electric power supply.

This inspection is of an informative nature. Only an inspection with measurable load using an test bench can be considered binding.

There is a semiconductor voltage controller to maintain input voltage within a certain range at variable rpm, variable load and at variable ambient temperature.

Regulated voltage will alternate on B+ terminal.

Cooling is provided via a cooling air fan, where direction of rotation has been identified.

The alternator must always operate with the storage battery connected – positive battery pole connected to the B+ terminal. NEVER disconnect the battery during operation.

Avoid any short circuits within the alternator circuit.

Disconnect alternator cables from the electrical system when performing any wiring repairs. When repairing wiring or performing welding, ALWAYS disconnect the alternator cables from the electrical system. When starting with an external auxiliary power supply, NEVER disconnect the power supply before the battery is connected. Do NOT start running the alternator with no load, i.e. with the cable disconnected from the B+ terminal and the D+ terminal connected.

Preconditions for proper operation are as follows: -

Undamaged wiring

-

Proper electrical connections on alternator, controller, storage battery terminals

-

Sufficient drive belt pull – permissible radial force acting on alternator shaft from belt pull along pulley axis is max 800 N.

Any failed alternator or controller may cause not only storage battery under-recharging but overcharging as well.

During normal workshop inspection of the entire power supply system (when no malfunction is expected), it is sufficient to check control voltage or how the indicator lamp reacts to increased rpm. With a voltmeter connected to the B+ terminal, the regulated voltage must move in the mean speed zone within 13 - 14 V range.

If the bulb of the recharging indicator lamp burns out, replace it immediately. No power will be supplied to the alternator if the recharging indicator lamp is defective. When washing the engine compartment, prevent water and dirt from penetrating into the alternator via the vents.

NOTE:During welding work on the machine you must disconnect alternator – wires from B+ and D+ terminals – and electrical units or instruments with semiconductor elements. Disconnect the storage battery before repairing other electric equipment.

SECTION 55 – ELECTRICAL SYSTEM – CHAPTER 17 TROUBLESHOOTING THE ALTERNATOR - CONTROLLER Inspecting the alternator-controller set using a test bench.

Remove the controller subassembly from the alternator complete with carbon brush holder and replace (reinstall) the subassembly with a controller that is known to be good.

Check regulated voltage on a test bench.

Inspecting an alternator with no controller – test bench.  Remove the controller subsystem together with brush holder and secure a modified brush holder to the alternator. On the modified brush holder, there is one brush cable connected to frame. On the second cable of the brush, there is a wire soldered incl. a socket for connector that will be connected to D+ terminal and continue for approx. 20 cm length to enable short-term energizing from B+ terminal.  Attach the alternator and connect it to a test bench with voltmeter, ammeter, load resistor, revolution counter and battery. Refer to the figure.  Get the alternator moving at about 1500 rpm.  Energize the alternator – attach the end of the free wire connected to the brushes and D+ terminal to the B+ terminal for 2-3 sec. If unable to energize, the alternator is defective.  Check alternator properties.

If no alternator defect is found, troubleshooting of the controller is required.

Poor contact between the alternator frame and vehicle frame or an improper storage battery ground connection could also be the cause of a fault.

Voltage controller An integrated voltage controller is involved. The alternator excitation circuit is connected between the DF and D+ terminals of the controller. The controller itself is connected to a brush holder and 2 bolts are used to attach the entire subassembly to the alternator. Its interconnection is made through three soldered circuits (B-, DF, D+) and a cable (rope) terminated with socket 6,3 to be slipped onto the alternator’s D+ connector. The controller cannot be repaired.

SERVICE MANUAL 17.4. Starter Motor

Checking idling – on the machine

Operation and Maintenance  For the starter motor to operate properly, it is essential to have an appropriate and fully charged storage battery.  The starter motor is designed for short-term operation.  Stop the start attempt once the engine starts – the starter motor pinion and bearing could otherwise be damaged.  Make sure feeder cables have cable heads perfectly tightened, with no broken insulation.  The starter motor frame forms part of the electric circuit. Keep contact surfaces on the engine metal clean and protect against corrosion.  If the starter motor does not work, search for a disrupted cable between the storage batteries and starter motor, between the engine frame and starter motor or between the engine frame and batteries.  Check the flywheel rim gear and pinion gear for wear and tear. When inspecting, lubricate with lube grease.  During engine repair or once every 2 years, repair starter motor of the machine. Check the commutator, brushes, brush springs and switch contact surfaces.

Make sure brushes are seated with 3/4 of their surface on the commutator and are able to slide lightly. Make sure contact surfaces of the switch contacts are not burnt out and bear on each other with their full surface.

Test the starter motor in such a position where the pinion is not engaged with the gear rim even when shifted out. When starter motor circuit is turned ON, the pinion must shift out and start spinning. An unloaded starter motor may operate for max. ten seconds. Refer to the section “Informative inspection of starter motor” for a detail description of such inspection.

Starter motor troubleshooting Connect terminal “30” of the starter motor to a properly charged battery, connect an ammeter with long effective range of wiring measurement to the circuit.

Start (supply current to terminal “50”). The strength of current while running on no-load must not exceed 120 A (peak upon instantaneous deflection is not taken into account). The starter motor must run quietly. The pinion must smoothly shift out and return to its home position. With the pinion out, the pinion should not spin right on the front of the cap ring. Slowing down (after-run) of the starter motor after the sensor is disconnected from the power supply may last only eight minutes. Check the pressure and condition of carbon springs. Carbons must be seated on the collector with at least 2/3 of the surface and must be able to move within the chambers. The armature must have perceptible axial clearance of max 1.3 mm (0.05 in). When pinion turns a bit in the direction of starter motor rotation, the starter motor overrunning clutch must slip slightly for a moment. If there is sufficient experience, the inspection with running on no-load is sufficient for workshop evaluation. However, we recommend testing on a test bench.
