2 GENERAL SAFETY
NEVER attempt to start the machine without sitting in the seat with the seat belt fastened. ALWAYS wear your seat belt when operating the POSI-TRACK. ALWAYS drive with the loader in the lowest possible position. Traveling with the loader raised causes the center of gravity (CG) to be raised, which increases the possibility of roll over in any direction. USE EXTREME CAUTION and common sense when traveling on inclines. Avoid sudden stops, excessive speed, and avoid obstacles. Sudden shifts in CG could cause roll over. NEVER use the POSI-TRACK to transport per-sonnel. Never let anyone ride on the vehicle or in the bucket. ALWAYS shut the engine off when adding fuel, oil, or water to the engine. Always shut the engine off when cleaning the radiator and oil cooler or when doing any maintenance or adjustments. NEVER get out of the vehicle when an attach-ment is running.
POSI-TRACK 4810
PAGE 10 ASV, INC.
NEVER get in or out of the operator’s seat with the loader in the raised position, unless the loader lock out pins are engaged. Lower the loader all the way down before getting out of the vehicle. Always step over the attachment when getting in or out of the vehicle – NEVER UNDER IT. THE SIDE SCREENS MUST be installed when the loader is attached to the vehicle. Fail-ure to install side screens could result in serious injury or death to the operator. ALWAYS use caution when carrying a load. Sudden stops can cause roll over. ALWAYS make sure all levers are in neutral before starting the engine. BECOME FAMILIAR with all controls and WARNING decals before operating the vehi-cle. NEVER allow an unqualified person to operate the POSI-TRACK. Anyone operating the vehi-cle must read and understand the operator’s manual. NEVER operate the POSI-TRACK on any fro-zen body of water. Ice can be very dangerous and unpredictable.

OPERATING INSTRUCTIONS Enter the vehicle when the loader is all the way down. Never enter the vehicle by going under a raised loader. (Fig. 7)
Adjust the seat forward or back so both feet reach the footrest and both hands reach the con-trols. Check to make sure all auxiliary levers are in
the neutral position and that the throttle is in the idle position. Fasten seat belt, and adjust so it fits snugly around your waist.
GENERAL OPERATION
!WARNING! Entering or exiting the vehicle under a raised loader could cause serious injury or death. Never put yourself underneath a raised, unse-cured, loader. (Fig. 8)
NOTE It is recommended that your elbows reach the arm rests on the seat. This will allow for steadier control over rough terrain and will also lessen fatigue.
!WARNING! Failure to wear the seat belt could lead to seri-ous injury or death.

Start the vehicle and allow engine to warm up for two minutes before increasing throttle to de-sired RPM. First time operators will want to learn at a lower RPM (2,000 or less) until they feel comfortable with the controls. It is also rec-ommended that the first time operator concen-trate on learning the drive controls before mov-ing on to the loader or other attachment controls. Place one hand over both drive control levers. Push both levers forward in unison to move for-
ward, and pull both levers back in unison to move in reverse. The further the levers are moved, the faster the vehicle travels in either di-rection. To turn to the right, push the left lever farther than the right lever (this makes the left track turn faster than the right track). To turn to the left, push the right lever further than the left lever. To turn the vehicle in its own axis (counter-rotate) push one lever forward and pull the other in reverse.
NOTE The engine will not start if the drive controls or the aux. hydraulic levers are not in neutral. Loader valve will not function unless the op-erator is seated.
NOTE For best performance, always put power to both tracks when making a turn. When both tracks are turning, the vehicle will turn easier, which also results in less damage to the ground.

HYDROSTATIC DRIVE POWER & SPEED CONTROL The POSI-TRACK transmits the power from the engine to the tracks using a hydrostatic transmission. The hydrostatic transmission sends oil under pressure to two individual hy-draulic motors, one for each track. The hydro-static transmission consists of two individual hydrostatic pumps. One pump for each motor. Track speed is increased by sending more oil to the hydraulic motors, and power is increased by sending less oil to the hydraulic motors. With a mechanical transmission the operator must shift down to increase power. With hydrostatic drive the operator can simply pull back on the drive controls, reducing speed and increasing power at the same time. HYDRAULIC RELIEF PRESSURE There are three main forces involved in trans-mitting power from the engine to the ground: ENGINE POWER, HYDRAULIC RELIEF PRESSURE, & TRACTION. Engine power and traction can be easily understood, however relief pressure must be explained in greater de-tail. All hydrostatic pumps have a “relief valve”. A relief valve makes the oil by-pass the hydraulic motor to prevent the pump from pro-ducing too much pressure. Every pump has it’s pressure limitations. The lower the pressure, the longer the pump, as well as other drive com-ponents, will last. The relief valves protect the vehicle from a damaging situation. For exam-ple: The relief valves minimize track damage and track derailment.
The hydrostatic pumps of the POSI-TRACK 4810 have relief valve settings of 4,000 lbs. psi. This means each drive pump can produce a maximum of 4,000 pounds per square inch of pressure. The harder the pumps are worked, the more pressure they will produced until they reach their relief valve setting. For example: It takes a certain amount of force to push a large rock across hard ground. If it takes 6,000 psi of oil pressure to push this rock straight forward, each drive pump produces 3,000 psi for a total of 6,000 psi. Under good traction the vehicle will push this rock straight forward since the pumps have not reached their individual 4,000 psi relief valve setting. If the opera-tor tries to turn the vehicle while pushing the same rock, the load on the inside track will be less, and it’s pressure will decrease. The load on the outside track will be in-creased, thus increasing it’s pressure. If the outside track is getting good traction, the 4,000 psi relief valve setting can be reached, making the track stop until the load is reduced. The oil for both tracks could be made to go over the relief valves if the same rock was pushed up hill since it would take much greater force.

LOADER VALVE CONTROL (Fig. 11 and Fig. 12) To raise the loader, pull back on the joystick at a controlled rate. To lower the loader, push forward on the joy-stick at a controlled rate. To put the loader in “float” position, push the lever all the way forward with a quick motion. To curl the attachment, such as a bucket, move the joystick to the left at a controlled rate. To tilt the attachment forward, move the joy-stick to the right at a controlled rate.

LOADER LOCK OUT PINS The roll cage comes equipped with two retract-able pins that slide outward to secure the loader in the “up” position. It is critical to use these pins when there is service to be done on the ve-hicle, when the loader is up, hooking up a frame mount attachment, or when someone has to get in or out of the vehicle when the loader is up.
ENGAGING THE LOCK OUT PINS (Fig. 13) 1. Raise the loader past the top of the roll cage and turn off the engine. 2. Loosen the two knobs and pull down on the spring loaded rings. 3. Slide the pins outward until they stop, make sure the spring loaded rings snap back into place. 4. Turn the key to the “on” position, to unlock the loader valve (DO NOT START ENGINE). Lower the loader onto the pins.

OPERATING CAPACITIES
The operating capacity refers to how much addi-tional weight can be put into the 4810’s bucket while attached to the loader arms. This operating capacity is measured at the mid point of the low profile bucket. The operating capacity is 2,950 lbs. when the low profile bucket is quick attached to the loader assembly, and is at the farthest point from the vehicle (half way up). The heavier the attachment, such as a 4-in-1 bucket, the less the operating capacity will be. Moving the load farther from the vehicle, such as a tree spade, will significantly reduce the operating capacity.
THE MOST SIGNIFICANT FACTOR IN OPERATING CAPACITY IS THE DISTANCE BETWEEN THE FRONT PIVOT POINT OF THE VEHICLE AND THE CENTER OF GRAVITY OF THE MATERIAL BEING CARRIED.

MOVING DIRT WITH THE BUCKET Certain techniques can be used to become more efficient in moving dirt with the bucket. The following are simple guidelines for those who do not have much experience moving dirt. The POSI-TRACK’S loader is designed to push against the frame while leveling or digging dirt. Lower the loader all the way down until it stops against the loader-stop. Tilt the bucket forward until the bucket engages the ground. This is the proper position for dig-ging with the POSI-TRACK. (Fig. 14) In uneven terrain, it may be necessary to dig with the loader raised off the loader-stop, how-ever, digging in this manner should be kept to a minimum to reduce damage to the loader arms. Always move dirt with the bucket level with the ground. Never tilt the bucket all the way for-ward and use as a dozer blade. (Fig. 15) This puts tremendous stress on the bucket, the quick-attach, and the bucket cylinders. Damage to any of the previously mentioned can occur if the bucket is used in this manner. Never back drag with the bucket in this manner (Fig. 16). The bucket cylinders are fully ex-tended and can be exposed to great forces if the bucket catches on something solid. Using the bucket in this manner can cause the cylinders to bend.

SIDE HILLING Although the POSI-TRACK works well on side hills, extreme caution must always be used. Never exceed a 3 to 1 slope. This means 3 feet of run to every 1 foot of rise. (Fig. 17) When turning to go up hill while side hilling, the following technique should always be used: 1. Stop the vehicle and back the vehicle down the hill until the front of the vehicle is pointed in the direction you want to go. Then drive for-ward. (Fig. 18,19,20) 2. This turning technique will reduce the chance of track derailment and will also put less stress on the track system.

CAUTION While operating on a side hill, the more weight there is on the vehicle, the greater the chance of track derailment. Gravity is trying to pull the vehicle downhill, while the tracks are keep-ing the vehicle on the hill. The less weight that is on the vehicle, the less chance there will be for track derailment

GENERAL MAINTENANCE
BREAK-IN PROCEDURES Although all systems on the POSI-TRACK are tested at the factory to ensure proper op-eration, there are a few items that require a break-in period. Certain components need re-adjustment and others require special care within the first 100 hours of operation. PROPER BREAK-IN PROCEDURES ARE CRITICAL TO THE LONG TERM RELI-ABILITY OF THE POSI-TRACK. Extra care during this period will pay-off down the road. TRACKS Proper track tension plays an important part in the over-all performance of the Posi-Track. A track run too loose can cause premature track failure and cause the track to derail. Although track tension is set properly at the factory, the tracks will need an adjustment after break-in. Once the KevlarTM and other special materials in the track are pulled straight, minimal ad-justment will be required. The break-in pe-riod of a track can range from just a few hours to over 10 hours, depending on the track and how the vehicle is operated. The tracks on the POSI-TRACK 4810 are easy to tighten. It takes only a few minutes and will be well worth the time (See page 30 for track tensioning procedure.) After the ini-tial track break-in, the tracks may not need to be tightened for several hundred hours, how-ever, the tracks should be inspected daily and tightened as necessary.
CAUTION Failure to perform the proper break-in procedures will cause premature compo-nent failure.

PLANETARY DRIVES Each track’s final drive consists of a hydraulic drive motor, a planetary gearbox and an inter-nal drive sprocket. The planetary gearbox re-quires a break-in period for the lug nuts and for the planetary oil. The 9 lug nuts, which attach the sprocket to the planetary gearbox, are torqued to 115 ft.-lbs. at the factory, and should be re-torqued to 115 ft.-lbs. after 10 hours of operation. (Fig. 22) The planetary gearbox requires an oil change at 50 hours. The break-in time allows the gears in the planetary to properly mesh. This is a crucial oil change since the oil will have a high metal content. After this initial oil change, the planetary oil should be changed every 1,000 hours or annually. (Refer to page 31 for proper planetary oil changing proce-dure.)
Fig. 22
CAUTION Failure to change the planetary oil at the 50 hour break-in interval, will drastically shorten the life of the planetary gear box. Failure to follow this procedure will also void the warranty of the plane-tary gear box.

ENGINE OIL & FILTER CHANGE The normal oil change interval is every 500 ser-vice hours or six months. Engines, which are operated under severe conditions, may need the oil changed to be changed every 250 service hours or three months. Severe conditions in-clude the following: high temperatures, continu-ous high loads, and dusty conditions. 1. Run engine approximately 5 minutes to warm up oil. Shut off engine. 2. Remove oil drain plug beneath the engine compartment and allow to drain. After the oil has been allowed to drain, clean the oil drain plug and reinstall. 3. Remove oil filter element and dispose of properly or consult your dealer for analysis. 4. Clean the sealing surface of the filter mount-ing base. Ensure that all of the old oil filter gas-ket is removed. Apply clean engine oil to the new oil filter gasket. 5. Install the new oil filter. Tighten the oil filter until the oil filter gasket contacts the base. Tighten the oil filter by hand according to the instructions that are shown on the filter. DO NOT over tighten the oil filter. 6.

HYDRAULIC OIL & FILTER CHANGE One of the most critical systems on the POSI-TRACK is the hydrostatic system. The hydraulic oil should be changed every 500 hours and the hydraulic filters should be changed every 250 hours. These precision components require ex-tremely clean oil in order to have a long service life. Changing the hydraulic oil and filters at the proper intervals can prevent expensive repairs later down the road. Before beginning the procedure extreme care should be taken to ensure the vehicle is in a clean working environment. Precautions should be taken to prevent any debris from entering the hy-drostatic system. 1. Remove hydraulic oil drain plug (A) from bot-tom of reservoir. Drain into suitable container. 2. The three hydraulic filters are housed inside the loader tower service compartment on the side of the vehicle. (Fig. 32) 3. The filters are disposable spin on type filters. These filters can be removed by hand or by using a filter wrench. Always dispose of filters prop-erly. 4. Fill with new approved hydraulic fluid. The fill cap is located in the loader tower (Fig. 33). The level gauge is located on the floor of the cab.

PRIMING THE FUEL SYSTEM If the engine has run out of fuel, or the fuel sys-tem has been opened for service, it will be nec-essary to bleed the fuel system. 1. Loosen the bolt at the top of the fuel filter in order to vent (A). 2. Pump primer lever (B) until fuel flowing out the vent is continuous and free of air bubbles. Tighten the bolt at the top of the fuel filter.
3. Loosen the nut for the fuel inlet line at the fuel injection pump (C) in order to vent. 4. Turn the start switch to the RUN position (do not actually attempt to start the engine). Operate the priming lever for the fuel lift pump until the flow of fuel from the vent is continuous and free of air bubbles. Tighten the nut for the fuel inlet
line.
GENERAL MAINTENANCE
NOTE It is not possible to operate the priming lever if the cam of the fuel lift pump is at the maxi-mum lift position of the cam. If this occurs, rotate the crankshaft one revolution.
NOTE If engine still won’t start, it may be necessary to bleed air from fuel system at the injection nozzles. Refer to the Caterpillar Operation and Maintenance manual for this procedure.

PLANETARY OIL CHANGE After the initial 50-hour break-in change, the planetary oil should be changed every 1,000 hours or annually, which ever comes first. Before starting the procedure, the planetary case must be cleaned thoroughly. It is crucial that no dirt falls into the case when removing the plugs. In the drawer under the seat of the POSI-TRACK 4810, there is a kit which will make changing the planetary oil easier. This kit in-cludes a fitting and a hose. The kit is located in the drawer under the seat. There are two plugs, which are 180° from each other. One is for draining the oil, the other is for filling the oil. It doesn’t matter which plug is used for which part of the job.
1. Rotate the sprocket until one of the plugs is lined up with the u-shaped notch at the top of the bearing plate. This will also line up the other plug with the hole in the bottom of the bearing plate. (Fig. 44) 2. Attach the hose to the fitting and be prepared to insert the fitting into the drain hole. Remove the drain plug through the bottom hole and quickly insert the fitting with the hose. (Fig. 45)
NOTE Drive the POSI-TRACK for 10 to 15 minutes Before changing the planetary oil. This will warm up the oil and allow it to drain more thor-oughly.

3. Remove the top plug to vent the case and al-low the oil to drain. (Fig. 46) 4. Remove the fitting with the hose from the bottom plug and reinsert the plug. 5. Insert the fitting and hose into the top hole. Use a 32 oz. Bottle of 80W-90 gear lube or simi-lar container, which can be filled with gear lube. Attach the other end of the hose to the bottle. Squeezing the bottle slightly will help push the oil into the case. (Fig. 47)

TRACK REMOVAL In some cases removing the track is necessary to work on some undercarriage components. Using a floor jack or a forklift, jack the POSI-TRACK off the ground (Fig. 55) until there is approximately 4 inches between the bottom of the track and the floor. Jack stands specially de-signed for the POSI-TRACK can be purchased through your POSI-TRACK dealer (PN # 454-876) For occasional track tensioning, the screw jack that comes with the machine is fine, however, a remote hydraulic jack is best for track removal and installation. A remote hydraulic jack with all the necessary extensions can be purchased from your POSI-TRACK dealer. 1. On the inside and the outside of the under-carriage, there are two long slots. Loosen the bolts (A) that are in these slots (DO NOT RE-MOVE). (Fig. 56) 2. Place the jack between the sliding planetary mount and the undercarriage frame (Fig. 57). Jack the planetary mount back just enough so the track adjustment bolts can be removed. Af-ter the bolts have been removed, release the jack and remove it from the undercarriage. 3. On the inside of the undercarriage there is a steel tab (B) welded to the sliding planetary mount. This tab will allow the planetary mount to be jacked forward. (Fig. 58)

4. Insert the jack between the rear axle mount and the steel tab (Fig. 58). Jack the planetary mount forward until the jack is full stroke. Re-move the jack and add an extension to the ram of the jack. Continue jacking the planetary mount forward until it comes in contact with the undercarriage frame. 5. There are 4 bolts, which mount the carrier wheels to the undercarriage frame. The 2 bolts closest to the drive sprocket (C) need to be loos-ened enough so the assembly can hinge on them. (DO NOT REMOVE ). 6. Remove the other 2 bolts and hinge the as-sembly back until it hits the undercarriage frame. (Fig. 59) 7. Position yourself behind the drive sprocket and grab the bottom inside portion of the track. Pull the track down, getting the drive lugs to clear the 10" idler wheels and then pull the track to the outside. Do not attempt to get the whole track off yet, just get one row of drive lugs past the outside 10" idler wheel. 8. Pull the track up and off the drive sprocket. The track can now be pulled off the 10" idler wheels. Continue pulling the track off the top of the undercarriage and slide it out from be-neath the undercarriage. Pull the track forward and out to remove the track from the 14" idler wheels. The track is now off. (Fig. 61)

TRACK INSTALLATION 1. Place the track parallel to the undercarriage so the end of the track is even with the end of the undercarriage. 2. Pull the track up and onto the 14" idler wheels. Slide as much track as possible under the undercarriage. Pull the track up and on to the hinged carrier wheels. (Fig. 62) 3. Pull the track up and onto the drive sprocket. Get one row of drive lugs into the drive sprocket. Move one row of drive lugs past the 10" idler wheels. (Fig. 63) 4. Pull the rest of the track up and onto the drive sprocket, and then under the 10" idler wheels. 5. Hinge the carrier wheels back in place, and retighten all bolts. The track is now on. It only needs to be tightened. 6. To tighten the track, the jack can either be placed on the inside of the undercarriage be-tween the two steel tabs or on the outside be-tween the carrier wheel assembly and the sliding planetary mount (Shown Fig. 64). If the plane-tary mount starts to bind, place the jack on the other side. 7. Once the planetary mount is back far enough, place the jack between the sliding planetary mount and the rear axle mount.

CHECKING CHARGE PRESSURE The charge pressure refers to the oil that is sup-plied to the main drive pumps, this oil allows the pumps to shift. If the charge pressure is low, the drive pumps may not shift at all when the levers are stroked or they may shift sluggishly, resulting in erratic track behavior. 1. Open the filter access panel on the side of the vehicle. Locate the test port in the upper right hand corner (A). 2. Remove the cap and screw on a pressure gauge. 3. Start the engine and let idle. At an idle, the charge pressure should be between 280 to 320 psi when the oil is warm.
