I

SAFETY RULES NEVER COAST the machine down grades and slopes with the transmission in neutral or neutralized.

In case of closed type cabs, always keep an opening with the outside, to ensure a constant air circulation.

Choose and shift into the most appropriate gear to keep the speed required, thus preventing any loss of control.

Operators must thoroughly know the performances of the machine they are operating. When working on slopes or near sudden level drops of the terrain, avoid areas where ground is loose or soft since rolling-over or loss of control of machine could result.

Do not operate machinery in a condition of extreme fatigue or illness. Be especially careful towards the end of working shift.

Where noise exposure exceeds 90 dBA for 8 hours, wear approved ear protection.

Do not operate machine with brakes out of adjustment.

When counterweights are provided, do not work machine if they have been removed.

Operate the machine at speeds slow enough to ensure complete control at all times.

Overtaking maneuver must be performed only when absolutely necessary and unavoidable. Beware of possible uneven terrains, poor visibility conditions, the presence of other machinery or persons out of sight.

Travel slowly over rough terrain, on slopes or near dropoffs, in congested areas or on ice or slippery surfaces.

When backing, always look to where the machine is to be moved. Be alert to the position of exposed personnel. DO NOT OPERATE if exposed personnel enter the immediate work area. STOP THE MACHINE.

Operate the machine at a speed adequate to the working conditions in the site and slow enough to ensure complete control at all times.

Never use the machine as a work platform or scaffolding, nor other inappropriate operations (i.e. pushing railway cars, trucks or other machines).

Maintain a safe distance from other machines. Provide sufficient clearance for ground and visibility conditions.

Yield right-of-way to loaded machines.

Be alert of people in the operating area of the machine.

Maintain clear vision of areas of travel or work. Keep cab windows clean and repaired.

When operating a machine, know in advance what clearances will be encountered, overhead doors, cables, pipes, bearing load limitations of ground, bridges, floors or ramps.

When pulling or towing through a cable or chain, do not start suddenly at full throttle; take-up slack carefully.

When roading, find-out what conditions are likely to be encountered, clearances, traffic congestion, type of road surfacing, etc. Beware of fog, smoke or dust elements that obscure visibility.

Inspect carefully for flaws or troubles before using.

Avoid kinking chains or cables. Do not pull through a kinked chain or cable to the high stresses and possibility of failure of the kinked area. Always wear heavy gloves when handling chains or cables.

When crossing gullies or ditches, move at an angle with reduced speed after ensuring ground conditions will permit a safe traverse.

Be sure chains and cables are anchored and the anchor points are strong enough to handle the expected load.

Keep exposed personnel clear of anchor points and cables or chains.

Explore the working area to identify potential risks such as: slopes, overhangs, pits, demolition rubble, fires, ravines, ditches, soft terrain, heavy traffic, crowded parking areas, closed ambients. In such conditions, proceed with extreme care.

DO NOT PULL UNLESS OPERATOR'S COMPARTMENT OF MACHINES INVOLVED ARE PROPERLY GUARDED AGAINST POTENTIAL CABLE OR CHAIN BACKLASH.

Whenever possible, avoid going over obstacles such as rough terrain, rocks, logs highly irregular ground, steps, ditches, railroad tracks. When obstructions must be crossed, do so with extreme care at an angle, if possible.

Reduce speed, shift-down. Ease up to the break over point, pass the balance point slowly on the obstruction and ease down on the other side.

Be alert to soft ground conditions close to newly constructed walls. The fill material and weight of the machine may cause the wall to collapse under the machine.

In darkness, check area of operation carefully before moving in with machine. Use all lights provided. Do not move into area of restricted visibility.

In steep down-hill operation, do not allow engine to overspeed. Select proper gear before starting down grade.

If engine has a tendency to stall for any reason under load or idle, report this for adjustment to proper maintenance authority immediately. Do not continue to operate machine, until condition has been corrected.

Avoid side hill travel, whenever possible. Drive up and down the slope. Should the machine slipping sideways, turn it immediately downhill.

The grade of slope you should attempt will be limited by factors such as condition of the ground, load being handled, type of machine, speed of machine and visibility.

On machines supplied with suction radiator fans, be sure to periodically check engine exhaust parts for leaks, as exhaust fumes are dangerous to the operator.

II

SAFETY RULES If parking in traffic lanes cannot be avoided, provide appropriate flags, barriers, flares and signals as required.

Also provide advance warning signals in the traffic lane of approaching traffic.

There is no substitute for good judgement when working on slopes.

Avoid operating equipment too close to an overhang or high wall, either above or below the machine. Be on the look-out for caving edges, falling objects and slides. Beware of concealment by brush and undergrowth of these danger.

Keep head, body, limbs, feet, fingers or hands away from bucket, blade or ripper when in raised position.

Always disconnect the master switch before any intervention (i.e. cleaning, repairing, maintaining, refuelling etc.). Do the same when parking for prolonged periods of time to avoid accidental or unauthorised starting.

When pushing-over trees, the machine must be equipped with proper overhead guarding. Never allow a machine to climb up on the root structure particularly while the tree is being felled. Use extreme care when pushing over any tree with dead branches.

Never lower attachments or tools other than seated in operator's seat. Sound horn. Make sure area near the attachment is clear. Lower the attachment slowly. DO NOT USE FLOAT POSITION of hydraulic system.

When pushing trees with dead limbs, proceed with extreme care. Avoid brush piles, logs or rocks.

NEVER DRIVE OVER THEM or other surface irregularities that brake traction with the ground, especially when on slopes or near drop-offs.

Place master switch in OFF, securely block the machine and lock it every time you leave it unattended. Return keys to authorised security. Heed all shut-down operations of the Operation and Maintenance Instruction Manual are followed.

Be alert to avoid changes in traction conditions that could cause loss of control. DO NOT DRIVE on ice or frozen ground conditions when working the machine on steep slopes or near drop-offs.

Working in virgin and rough terrains is characterised by the presence of all the perils and risks listed above. In these conditions, it is emphasised the danger represented by large tree limbs (possibly falling on the machine), large roots (acting as a leverage under the machine when uprooted causing roll-over of the unit) etc...

TRANSMISSION Hydraulic torque converter with max. stall torque ratio 2.33 : 1.

"Powershift" transmission providing three forward and three reverse speeds, with ELECTRONIC sliding control. Moving the joy-stick to neutral the transmission is disengaged.

AUTO KICK DOWN function button and AUTO SHIFT function button.

Safety lock lever preventing, in "lock" position, the operation of the pilot gearshift, automatically engaging the service brakes.

Torque converter/transmission oil cooling by water type heat-exchanger recirculated from the engine radiator.

Transmission oil filtered by two total flow filters; one metal mesh and magnetic rod on suction line, the other cartridge type with by-pass valve on delivery line.

Reduction units Central bevel gear type reduction in the centre of rear transmission housing.

Double reduction modular type final drives.

Reduction ratio: 1 : 10.8 POWER STEERING DIFFERENTIAL The differential steering provides the steering without ever stopping the track chain, by transmitting the power with continuity to both track chains during the steering phase, also during tight steering maneuver.

With the two track chains constantly working, it is possible to push larger loads, also at maximum speed.

The steering occurs by increasing the speed of one track chain and slowing down the other one the same amount; the speed difference makes the machine steering. The steering system operates as a differential and it is composed of: a pump, a hydraulic motor and the relevant controls operated by just the movement Joy-stick.

BRAKES Oil-bath disc brakes A single pedal in the cab actuates a single central brake blocking the motion of the bevel gear and operates both as service brake and as parking brake.

A manual system allows the disengagement of the brake in the event there is no hydraulic pressure to tow the machine in case of failure.

Parking brake: automatically engaged, by the transmission safety lever ON or with engine inoperative.

EQUIPMENT HYDRAULIC SYSTEM The equipment hydraulic system is a combined circuit with the steering system and Load-sensing circuit, to manage with maximum efficiency, the hydraulic power required by the two circuits using the same hydraulic oil, being divided by the different operating pressures.

The system operates with a logic priority to the steering when power is required at the same time, by the equipment as well.

The equipment system is mainly composed of: - A variable displacement piston pump and a hydraulic oil control valve shared by the steering system.

- An oil tank located at the rear end of the machine, with two visual level gauges (MIN-MAX).

- Oil filtration by two full-flow filters. one a metal mesh on the suction line of the pump; a filter equipped with safety "by-pass" in case of clogging, on the oil return to the tank.

The monoblock control valve has four spools, with the PAT blade version has 5 spools.

Single lever pilot control valve for the first 3 spools of the control vale for the following functions: - Blade raising/lowering and floating - Blade tilting - Blade angle (only for version with PAT blade) - Two double stroke hydraulic cylinders control the blade raising, with stroke-end valves and quick-drop valves 8for the Bulldozer version) installed on the upper bottom.

Upon request, a 3rd function supplementary lever to control the ripper. Safety lever on the equipment and transmission controls in neutral position, located at the right side of the operator, with the purpose of preventing an accidental actuation. The version equipped with PAT blade offers a further possibility of angling rightward or leftward the blade using two buttons located at the tip of the blade control pilot valve.

OPERATING INSTRUCTIONS GENERAL INFORMATION Before placing the machine in motion, be certain it has been properly prepared for use and has been properly serviced since the last operating period. Refer to the chapter "PRELIMINARY INSTRUCTIONS AND BREAK-IN PERIOD" for detailed information.

If repairs have been made during the last period of inactivity of the machine, ensure that all bolts and nuts of the components involved are properly tightened and that all necessary adjustments are made.

PRIOR TO STARTING (DAILY) By reacting promptly as soon as troubles develop it is possible to reduce maintenance costs and machine downtime. Thus, it is recommended that, every day, prior to starting or at the end of the day, a walk-around inspection is done, performing the following operations: - remove dirt, mud, oil and snow from the machine; - check if there are oil leakages.

DANGER In case it is difficult to identify the cause of leakage due to the presence of dirt, clean the component to be inspected.

Start the engine to identify coolant or oil leakages.

Oil leakages under pressure are dangerous since hydraulic oil could penetrate the skin.

Do not try to locate leakages from the hydraulic system using bare hands. Use a piece of cardboard.

- Check for damaged hoses and pipes in the hydraulic system.

- Check the engine oil level and the presence of contaminants in the oil.

- Check fuel level in the tank.

- Drain water from the sedimentation filter.

- Check the coolant level and the presence of dirt on the radiator fins.

- Check the engine air cleaner restrictor indicator.

- Check the operation of instruments and indicator lights on the dashboard, lights, horn.

- Check the hydraulic oil level.

- Check the torque converter/transmission oil level.

- Check the operation of the throttle pedal, the color of exhaust fumes and the exhaust noise.

- Check the ROPS cab, safety belt for damages and the loosening of securing fixtures.

- Prior to operating the machine, warm-up the various components, without considering the season.

Long storage of the machine If the unit is going to be inoperative for a long time, comply with the following rules: - Clean the machine completely and lubricate all components equipped with grease fittings.

- Drain the water from the cooling system. If the system is filled with an antifreeze mixture, this operation is not necessary.

- To avoid rusting, it is necessary to refill completely the fuel reservoir.

- Remove the injectors and inject, through the injector holes, some engine oil (the operation should be performed using a syringe, after moving each piston to B.D.C.).

- After injecting the oil, crank the engine a few turns using the starter motor, so as to spread a protective film of oil on the sleeve walls. Then reinstall the injectors.

- If possible, store the batteries in a place where there is no danger of freezing. Recharge them monthly.

Cold climate precautions When ambient temperatures are near 0 °C (32 °F) make sure that the cooling system is filled with an antifreeze mixture, to prevent the danger of freezing, otherwise, replace the water in the system with such a mixture.

Flush the cooling system before adding the antifreeze mixture. Use appropriate specific products for this operation, following the instructions on the container.

WARNING Remove the radiator cap only after the engine has sufficiently cooled-off. With engine inoperative, turn the cap slowly so that residual pressure is released before removing it completely.

The use of CASE coolant is recommended. Please find in the table below the percentages of the mixture related to ambient temperatures:

WARNING To recharge the batteries, a slow charge is preferable.

Should booster batteries be used, remember to connect both ends of the booster cables in the proper manner (+) with (+) and (-) with (-). Avoid short-circuits of the terminals.

Place the machine in a protected place or cover it with a tarpaulin.

To ensure an adequate protection of the transmission components, at least once a month, the machine should be moved for short distances, so that a film of oil is renewed on the parts.

MACHINE OPERATION WARNING Never attempt to operate the machine or its equipment from any position other than seated in the operator's seat. In all circumstance, keep head, body, limbs, feet, hands and fingers within the operator's compartment to minimise the possibility of exposure to external dangers.

Keep all equipment low or in a position ensuring maximum visibility and the control of the machine.

Never use the equipment as a platform to lift personnel nor to carry riders on the machine.

When pulling or towing through a cable, do not start suddenly at full throttle; take-up slack carefully.

Use only designated anchoring points when pulling or towing. Take extreme care when hooking.

Make sure that pins and locks are properly secured before pulling.

Keep exposed personnel clear of the equipment (or supplementary attachments) when raised, to avoid possible injuries.

NEVER COAST the machine down grades and slopes with the transmission in neutral or neutralized.

Explore the working area to identify potential risks such as: slopes, overhangs, pits, demolition rubble, fires, ravines, ditches, soft terrain, heavy traffic, crowded parking areas, closed ambients. In such conditions, proceed with extreme care.

Working on slopes is dangerous.

Pay special attentions when working near overhangs.

Always designate a flagman when visibility of the working place, by the operator, is limited. The flagman must be capable of communicating directly with the operator and the latter must obey the signals.

Be aware of falling walls, falling objects and landslides. Always remember that these dangers could be concealed by brushes, undergrowth etc.

When working in ditches or near high embankments, make sure that the walls are adequately supported, so as to prevent landslides.

Before working in the vicinity of gas lines or other utility lines always contact the nearest utility office before beginning work.

You and the utility representative must jointly determine what specific precautions must be taken to insure safety.

Work in proximity of overhead or underground power lines involves serious body injuries and death hazards, thus special precautions must be taken according to national and local safety regulations.

For the purposes of this Manual you are considered to be working in the proximity of power lines when the attachment or the load raised by machine, in any position, can reach to within the minimum distances specified by local and national safety regulations.

Slow down working speeds. Reaction times could be too slow and distances could be erroneously evaluated.

PRACTICAL OPERATION TIPS It is good practice, when the operator first gets on the machine, to familiarize with its controls.

The operator must perform all the operations the equipment is capable of doing, to develop sufficient "feeling" with the controls and their reaction.

Remember that, when the control levers are in neutral position, the equipment is solid with the machine: this means that it will follow along any movement of the machine.

Dozing When working on grades, it is best to move downhill for better traction. Gradually lower the blade at the beginning of each pass and accelerate the engine fully. The dozing depth should be such as to allow a load within a short distance (5-6 m /15-18 ft); the full load should, then, just be pushed to the unloading area.

When the ground is hard, getting a full load in a short distance becomes difficult. Under these conditions, instead of pushing a half empty blade towards the unloading area, it is better to return to the starting point and doze more. The load of the second pass is added to the first one and will result in more effective dozing, especially when the unloading distance is considerable.

Working is often made more difficult when large rocks are present and are caught under the blade and pushed forward or lifting the front of the machine, making uneven cuts. This humped effect can be avoided by backing-up with the blade at a lower depth capable of dislodging the rock. If necessary, operate with the moldboard corner tilted.

When dozing in hard terrain and the blade is unable to cut the material, it is advisable to increase the moldboard's draft.

Under these conditions the angle is good for the initial cutting, but during continued dozing the moldboard will pick-up more resistance as the load will push the blade upward. Also, a high pitch reduces the rolling of the material on the blade, increasing the resistance. In hard and rough dozing, the operation might be easier if the blade is tilted; if the work to done is over a considerable area, first use the ripper to break-up the soil.

Road and ditch cutting When cutting steep slopes (for roads or ditches) dozing should begin by cutting the depth of the ditch and tilting the blade to cut the sides with the desired angle.

Care must be taken in monitoring that the profile of the slope is regular, as any correction would be most difficult or, in some cases, even impossible.

Fording depth The fording depth is an important factor to be considered when the dozer works in marshland conditions.

Never enter into water deeper enough to reach the engine fan blades. As a general rule, the MAX allowed depth is about 500 mm (20 in).

Follow these rules: - check the depth of the water prior to fording water; - implement the same precautions, before entering a marshland.

Note – Avoid operating the dozer in seawater. Salty water causes the development of rust, reducing the life of the machine.

After working in marshland, wash the machine and apply some protective coating.

Pushing loads When pushing materials have the tendency to spill out the sides of the blade. This problem can be reduced by working repeatedly, when possible, following the same path on successive trips so that the spills forming windrows on both sides prevent a further loss of material from the blade. When pushing loads on a level terrain, keep the blade just touching the ground or at a depth deep enough to skim the surface. However, if the terrain is uneven it is appropriate to cut a little deeper to compensate the dirt which falls out the sides or in the hollows.

Steering The 1650K solves steering difficulties, especially during the material-pushing phase, since it provides constant power to both track chains, under all conditions, making the machine steering in a natural manner.

Thus traction and ease of operation result, as well as a more uniform ground surface (not damaged by the blocking of the track chains), limiting the loss of material previously accumulated, during the steering.

Spreading When spreading materials, hold the blade slightly above the ground, so that it can slide under the cutting edge, creating an even layer.

If the layer to be spread is of a considerable height, let the blade rest at a height just above the desired layer, since the compactation occurring later will lower the layer, especially when loose materials are involved.

Grading After the ground has been dozed, the surface might be rough due to small windrows, ground lifted by the tracks or small piles left around turning points. These terrain irregularities must be smoothed over by operating the dozer in reverse and leaving the blade floating.

Under these conditions, the blade operates as a harrow, topping off high spots and filling voids, without altering the level.

Grading is often made difficult, and sometimes impossible, because of boulders or other debris, which have to be removed first.

Moving large rocks and boulders It could become necessary to move boulders with the dozer, during all kinds of works. There are several procedures. In fact a fully loaded blade may be used or the boulder can be pushed directly by the blade by the forward or reverse action of the machine.

The choice of procedures used depends upon several factors: the dimensions and shape of the boulder, space available, type of work being performed. With tractor in forward and fully loaded blade the boulder can be moved by glancing it off the load; in this manner the rock will roll-off to the nearest side of the machine.

Repeating this type of maneuver will eventually edge the boulder from the working area.

The same result can be obtained by maneuvring in reverse. In such a case, turn the machine so that the side of the blade contacts the boulder, while the blade pushes the rock backward and sideways.

Piling To pile materials, two well accepted methods are recommended: Form a pile of material on the first pass, then, with successive passes, accumulate material in front of the established pile.

After forming an initial pile on the first pass push material on successive passes to the top of the established pile and make it fall over the opposite side.

Sometimes, instead of piling it, the material is pushed to fill a ditch. In this case, since the filling material tends to let the machine sink it is appropriate to build a small step before reaching the edge of the ditch, raising slightly the blade.

This step improves safety since, proceeding with subsequent passes, the front of the tracks shall allow, in steps, to protrude over the original edge.

PILING

A

B

Pile levelling If the pile is not too bulky or hard, it can be levelled by dozing the blade into it, than it can be spread or re-piled somewhere else.

If the pile is too large or too hard to be spread with a single pass, or it must be spread in different directions, the first pass may be made grading one side to ground level, repeating the cuts, as required from different angles, on the remaining pile. If the dozing leaves high walls which could fall on the machine, turn the blade from time to time toward the wall and with it raised, push the mound down.

If the dozer is unable to cut a pile because of its steep sides, a ramp can be built by pushing into one side with the blade raised and then backblading with a down pressure.

The levelling of a pile can also be made by dozing a centre slot and continually cut away the top. This method is always recommended when the pile is excessively high and it is the only possible when there no access to the side of the pile.

The centre slot with must be quite greater than the width of the blade, thus allowing a protective border to be built preventing the dozer from getting trapped, once the digging reaches a certain depth or boulders and earth or the walls collapse on the machine.

Also, a narrow cut does not allow the machine to properly manoeuvre and dispose of rocks or roots encountered while dozing.

Going over obstacles Any obstacle (logs, roots, ridges etc.) must be removed, if possible, or avoided. If this is impossible, crossing must be done very slowly and at an angle so that one track will reach the top and starts to descend on the other side, while the track is still climbing. This method of operation slows down the dropping and decreases the shock against the ground, which could cause damages to the machine and the operator.

If the obstacle is made of soft material it is good practice to sharply turn the machine while crossing, so that the track edges will help cut the material down.

When the dozer is operating in heavy work, the tracks often spin, forming small pile of earth near their rear end. Under these circumstances, when reversing direction, it is good practice to move sideways as much as required, to avoid the tracks hitting these windrows.

A ditch may be crossed without danger only if its width is not greater than 1/3 the track length and if the track movement will not collapse the banks. To prevent the latter from occurring, move the machine over wooden planks, even if not very strong.

Hill work Dozing on side slopes requires special care. Even when the dozer appears to have sufficient margin of safety, the sudden running over an unseen obstacle by the upper track or the lower track moving into a hollow, the machine could tip over.

Chances of this occurring are lessened when the machine is dozing as it is moving along using the load as an additional stabiliser. Also, the machine is stabilised by the low windrow.

Dozing on frozen slopes is hazardous as the grousers act as skates causing the machine to slide uncontrolled downhill. There is a danger of tipping over rocky slopes as well, especially shale with beds parallel to the surface and on soft fills where the lower track sinks deeper than the upper one.

If the machine starts to slowly roll over, sometimes it is possible to prevent the trouble by quickly turning downhill, lowering the blade at the same time.

Slopes too steep to be safely worked sideways, sometimes, may, be dozed by operating the machine along it diagonally.

On the other hand, the machine overcomes safely steep slopes downhill. Steering is apt to be tricky on steep slopes, whether up or down, because when one steering clutch is released, the track on that side slips and turns faster and the machine pulls to this side under gravity and might place itself transversally of the grade with the consequent danger of tipping over.

Digging and pushing should be done downhill to obtain a better pushing effort. This is particularly advantageous when the ground is very tough, even if the soil must be pushed up the hill. When digging is limited to a given area on the slope and material must then be pushed downhill, it is a good technique to drop to or three loads at the end of the cut, then pushing most of the pile down in a single pass.

252

Notching a shelf on side slopes, travelling across the slope, steering and unloading downhill.

Grading on side slopes If a slope must be notched (i.g. road cuts in hillsides) it will be necessary to first build a shelf. Set the blade in tilt position opposite to the slope so the dirt moved will slide downhill and help in building up the shelf. If the slope is too steep to work effectively with tilted blade, proceed in one of the following ways: Push the material downhill to form a shelf as in (A), so the dozer can start level cuttings, as in (B).

Dig a strip transversally to the slope, then proceed with a series of parallel cuts, always operating the higher track in the previous strip.

In each case the best possible advantage should be taken with the soil configuration. When natural aids are not available, the machine can be moved onto boards or other lifts to start the cut at the desired slope.

Clearing In land clearing of brush and small trees, clearing can be accomplished in one pass, with the blade cutting slightly below the ground. This will allow the blade to shear the roots. It may be necessary to back up occasionally to clear the roots from the cutting edge.

Roots under the edge cause the blade to ride up and waste machine power.

When uprooting a tree, first place the blade fully raised against the trunk, then engage first gear forward and push with the engine fully accelerated. If the tree resists, shift the transmission to neutral then into first forward again; repeat a few times. If the tree does not fall quickly, make a few passes to cut some of the outlaying root structure. To improve the pushing, buildup an earth ramp opposite the direction the tree is to be felled, so that the blade can touch the tree in a higher position. Remember, when the tree begins to fall, to back-up rapidly, so that the uplifting roots will not catch under and tilt over the machine.

Operating tips Before beginning to doze, the moldboard should have proper tilt and pitch for the work to be done. While dozing, always use a speed adequate to obtain best results from the machine.

To get smooth cuts, (meaning regular surfaces) the operator should watch the ground pattern closely and when the machine noses down or up, he must react swiftly with the control lever to raise or lower the blade, as required.

Note – Keep the cutting edges in good conditions.

RIPPER The ripper is supplied as an optional.

To raise or lower the ripper, move the control lever backward or forward, respectively. To stop the ripper in the desired position, release the control lever which will return to hold position in neutral.

The ripper is equipped with shanks/teeth removable from the relevant frame, as required. Thus it is possible to work with all the teeth or, in particularly heavy conditions, with the central one only.

Engage FIRST gear for all ripping operations. Use more shanks rather than increasing travel speed.

To obtain the best results, the following considerations should be kept in mind:

Breakage The soil can be broken in fine or coarse pieces, as required. It depends on work depth, number and shape of the shanks and pass spacing.

Breakage must be established on the basis of the subsequent use of the ripped material. As an example, if the material must be spread and back bladed, a finer breakage is required than when it must be dozed away.

Work depth It is good practice to work to maximum depth permitted by the available power and traction of the machine, taking into account the breakage desired.

Note that: - With strongly cohesive materials, such as clay, tuff, marl, gypsum, sandstone, calcite and other compact soils, the greater the depth the coarser the breakage; - With stratified materials, such as limestone, schist, gneiss, travertine etc., the greater the depth the finer the breakage.

Number and shape of teeth The number of teeth depends on the power required of the machine in relation to the desired breakage.

Generally, the greater the number of teeth, the finer is the breakage. Exceptions are stratified materials where large slabs are lifted when working with more than one tooth.

As regard tooth shape, the partially curved type can be considered a universal standard. Curved teeth facilitate the lifting and to some extent, also the turning over of the material.

Carefully read personal and machine SAFETY PRECAUTIONS (at the beginning of this manual)

1650K

59

Spacing between passes It must be such as to complete the breakage of the previous pass, always in relation to the desired fineness. Generally, spacing must be less than work depth.

In plastic soils, e.g. gypsum (in which the implement makes just a cut) or in hard soil (in which the working depth must be reduced) criss-cross passes may be required.

Speed and direction It is good practice not to exceed 1.5 - 2 kmph (1 to 1.2 mph) to prevent harmful shocks to the implement and excessive wear. When working on soft material, it is preferable to increase the depth rather than the speed. In the case of stratified materials, work crosswise and against the vein; on the contrary, if the material is landslipping. work in the direction of the landslide.

1850-2M0098

Notice – Do not reverse or steer while the teeth are into the ground. Torsional forces could breake the teeth.

Material heaping Generally it is convenient to heap material crosswise to the ripping direction in order to keep the transport distance to a minimum and to smooth out any irregularity.

WARNING To make sharp turns, raise the ripper teeth off the ground, to prevent damages. Only wide turns or small directional corrections are permissible when the ripper is sunk-in.

With surfaces with deep depressions, first make passes to level the ground, prior to ripping, to avoid breaking the shanks.

WARNING When not in use, always carry the ripper in full raise position during operation and lowered to the ground when parked.

MAINTENANCE

MAINTENANCE SAFETY WARNINGS Do not allow unauthorised personnel to perform any maintenance operation. Study carefully this Manual before starting, operating, maintaining, fuelling or servicing the machine.

Never perform lubrication, repair or adjusting operations with engine running, except as specifically called for in this Manual, to avoid being caught by moving parts or being crushed by the machine.

Follow the instructions of chapters "Stopping the machine" and "Stopping the engine" in the Operation and Maintenance Instruction Manual, before lubricating or performing any other intervention.

Always lower the equipment to the ground and release pressure from all systems prior to proceeding with any maintenance or repair work.

The equipment and attachments can be lowered by moving the control lever with engine running or inoperative.

Every time components of the machine must be removed, be sure the jacking point used on the machine is appropriate for the load to be applied.

Be sure the support of the jack at the machine and under jack is appropriate and stable. Transfer load to appropriate blocking as a safety measure, before proceeding with service or maintenance work.

Never work over or under a machine or its components being supported only by jacks or other lifting devices, in accordance with current national and/or local regulations.

Never work under or near the equipment of a machine or its components not adequately supported and blocked.

Always place the safety levers in lock position.

Always place the starter switch in lock position prior to perform cleaning, repair or any other intervention on the machine and after parking it, to prevent personal injuries.

Never use gasoline, solvent or other flammable fluid to clean parts. Use exclusively qualified, nonflammable, non-toxic commercial solvents.

DO NOT USE HANDS to search for suspected pressure leaks. Fluid escaping under pressure nd can have sufficient force to penetrate the skin.

When servicing or maintenance require access to areas that cannot be reached from the ground, use a ladder or step platform that meet local and national regulations, to reach the service point. If such ladder or platform are not available, use the machine hand holds and steps as provided. Perform all service or maintenance carefully.

Use only grounded auxiliary equipment to power heaters, battery charges, pumps or similar equipment, to reduce the risk of electrocution.

Warn all personnel which could be performing repairs or in the vicinity of the machine prior to starting the engine.

Keep hands, limbs and face away from loosen connections of pipes when performing efficiency or leakage tests of injectors or systems. Also, wear proptective glasses with side shields.

NEVER ALIGN HOLES WITH FINGERS OR HANDS; always use appropriate aligning tools.

Do not use an open flame as a light source to look for leaks or for inspection anywhere on the machine, due to the presence of flammable fluids.

MAINTENANCE OPERATIONS The service intervals indicated herein refer to normal operating conditions; during the initial break-in period and under particularly severe conditions, other intervals may be needed.

Use this list to co-ordinate maintenance scheduled at the same intervals.

Before proceeding with any service operation, lower the equipment to the ground and shut-off the engine.

It is advisable to change oil immediately after stopping the machine as warm oil will drain out more easily, along with any suspended deposit or scale.

Before and after lubrication operations, accurately clean all fittings, covers, plugs to prevent dirt from entering the system.

Lubrication is an essential part of preventive maintenance, controlling to a great extent, the useful life of the unit. Different components require different lubricants, and some components in the unit require more frequent lubrication than others. It is important that the instructions regarding types of lubricant, and the frequency of their application, be followed. periodic lubrication of moving parts reduces to a minimum, the probability of mechanical failures.

Note – Do not tamper with the fuel injection equipment setting, otherwise CASE will void all warranties.

WALK AROUND INSPECTION (to be performed daily) By quickly responding to initial troubles, required maintenance and downtime will be reduced. It is recommended to check the machine each day, before beginning work or to make a walk around inspection at the completion of each day to check: A. Side final drive oil leakages B. Ineffective or broken instruments C. Engine oil/coolant leakages

D. Hydraulic system leaks and damaged hoses E. Caked dirt on radiator grill F. Blade wear or damage H. Track rollers and idler wheel oil leakages I. Track tensioner grease leakages L. Caked dirt and mud on track frames M. Loosen track shoe fasteners
