COOLING SYSTEM

Maintaining cooling system efficiency is important.

Engine temperatures must be brought up to and maintained within the satisfactory range for efficient operation. However, the engine must be kept from overheating in order to prevent damage to the valves, pistons, and bearings.




Clean the engine cooling fins after every 25 hours of operation.

2. Open the filter cover to gain access to the engine.

3. Remove the air filter cover wing nut.

AIR INTAKE SYSTEM

The importance of maintaining an air filter in proper condition cannot be overemphasized. Dirt induced through improperly installed, improperly serviced, or inadequate air filter elements wears out more engines than long hours of operation.

Even a small amount of dirt will wear out a set of piston rings in just a few hours. Operating with a clogged air filter element also causes the fuel mixture to be richer, which can lead to formation of harmful sludge deposits in the engine. Always cover the air intake when the air cleaner is removed for servicing. Do not neglect servicing the air cleaner. Use only correct parts for replacement. Keep all other air intake components such as hoses, clamps, etc., secure and in good condition to prevent entrance of unfiltered air.

FUEL SYSTEM -- GASOLINE

FUEL FILTER

The fuel filter traps fuel impurities. It is located below the air filter. Replace the filter when diminished fuel flow indicates a dirty filter.

CARBURETOR

The carburetor needs no regular maintenance. It is set so there is no idle speed----only the normal operating speed. The initial setting of the idle and main fuel needle valves is made by turning them all the way in. Turn the idle fuel adjusting needle counterclockwise to a minimum of one and one-quarter turns to a maximum of one and one-half turns. Turn the main fuel adjusting needle out counterclockwise to a minimum of one and three-quarters turns to a maximum of two turns open. Final adjustment is made with the engine running and warm.

1186 MM267 (6--94)

MAINTENANCE

The carburetor should be adjusted with the fuel tank approximately one-half full and with the engine running at approximately 800 RPM. Turn the main fuel adjusting needle valve out until the engine begins to lose speed (rich). Note the position of the needle. Then turn the needle in.

The engine speed may increase, then it will decrease as the needle is turned in (lean). Note the position of the needle. Set the needle half way between the rich and lean positions.

FUEL SYSTEM -- LPG

LPG FUEL SYSTEM

The vapor withdrawal LPG fuel system is made up of four components which are: the LPG fuel tank, fuel filter lock, the regulator, and the carburetor.

LPG fuel flows from the LPG tank, under its own pressure, to the fuel filter lock. The fuel filter lock filters unwanted tank scale and deposits out of the

LPG fuel. The fuel filter lock also stops the flow of

LPG fuel when the engine is not operating. The

LPG module controls the fuel filter lock. When the charging system produces sufficient energy, it permits an electrical current to open the fuel filter lock which allows LPG fuel to flow on to the regulator.

The regulator reduces the pressure of the LPG fuel to the level required by the carburetor. From the regulator, the LPG fuel is sent to the carburetor where it is finally metered into the combustion chamber air flow.

Never operate an LPG powered machine if the

LPG fuel system is leaking, or if any component in the fuel system is malfunctioning. Operating the machine under either of these conditions may cause a fire or explosion.

Check for frosting. If frosting occurs on or near any LPG component, there is a possibility of an

LPG fuel leak or a malfunctioning component. To locate the leak, apply a soapy water solution to the suspected area. Watch for bubbles forming in a suspected area indicating an LPG fuel leak.

Repair or replace the part. Use Loctite brand

Stainless Steel PST thread sealant when reassembling. This epoxy-type sealant is not affected by aging or high humidity. Be sure to follow application directions and apply proper torque when reconnecting fittings. Never bypass safety components except to test. If the safety components are defective, replace them before operating the machine.

Check routings of all LPG hoses. Keep them away from sharp edges, exhaust manifolds, or other hot surfaces. Check for signs of abrasion or deterioration. Replace hoses found to be worn or damaged.

FUEL TANKS

The LPG fuel tanks should be inspected for sharp dents, gouges, leaks, and broken protecting rings whenever the tanks are refilled. All tank valves must be inspected for leaks using a soap solution.

Valves must also be checked for dirt, paint, or other debris in the valve openings. The following specific checks must also be made:

Filler Valve -- Check for proper functioning and the presence of the handwheel. Valve must be closed except during filling.

Vapor and Liquid Service Valves -- Check for proper functioning and presence of the handwheel. The valve must be closed except when in service.

Tank Service Valve Coupling -- Check for proper functioning, thread condition, and damaged or missing washers or o-rings.

Safety Relief Valve -- Check for damage. Check for the presence of the relief valve elbow and the proper direction of the elbow. If the rain cap is missing, check for foreign matter and replace the rain cap. Do not tamper with the relief valve setting.

Magnetic Liquid Level Gauge -- Check operation against the maximum filling point as determined by weight.

An LPG fuel tank with any of the stated defects must be removed from service and be repaired or destroyed accordingly.

If an LPG fuel tank is damaged or leaking, it should be removed to a designated safe area, and the proper personnel should be notified. Do not attempt to make repairs to the tank, regardless of condition. Repairs or disposal must only be made by qualified personnel.

3-10 1186 MM267 (6--94)

The care an LPG fuel tank receives has a direct bearing on how long that tank can be used safely.

LPG fuel tanks must not be dropped or dragged across any surface. To move LPG fuel tanks, use a hand truck or roll the tank on its foot ring while it is being held in a position slightly off vertical.

Whether the storage is inside or outside, fuel tanks should not be stored in the vicinity of combustible materials or high temperature sources such as ovens and furnaces, since the heat may raise the pressure of the fuel to a point where the safety relief valves would function. Tank care to insure that the tanks are stored in such a way that if the safety relief valves do function, they will relieve vapor, rather than liquid.

Valves on empty tanks must be closed during storage and transportation.

Similar precautions should be taken in storing machines fitted with LPG fuel tanks. The machines may be stored or serviced inside buildings, provided there are no leaks in the fuel system and the tanks are not overfilled. While machines are being repaired inside a building, the shut-off valve on the tank must be closed, except when the engine must be operated.

Changing the tanks is a chance for the machine operator to carefully observe the tank, fittings, and the fuel lines and fittings. If abnormal wear is detected, the operator should notify the appropriate personnel for appropriate action.

TO CHANGE AN LPG FUEL TANK

1. Park the machine in a designated safe area.

FOR SAFETY: When Servicing Machine, Keep

Flames And Sparks Away From Fuel System

Service Area. Keep Area Well Ventilated.

2. Close the tank service valve.

3. Operate the engine until it stops from lack of fuel.




MAINTENANCE

4. Put on gloves and remove the quick-disconnect tank coupling.

5. Inspect the LPG fuel lines for wear or damage.

6. Remove the empty LPG fuel tank from the machine.

7. Check the tank for damage or wear.

8. Store the tank in a designated safe area.

9. Select a filled LPG fuel tank and inspect it for damage or leaks.

NOTE: Make sure the LPG fuel tank matches the fuel system (vapor tank with vapor system).

10. Carefully place the LPG tank in the machine so that the tank centering pin enters the aligning hole in the tank collar.

NOTE: If the pin cannot be engaged, make sure you have the correct LPG fuel tank and then adjust the pin locator in or out.

11. Fasten the tank hold-down clamp to lock the tank in position.

12. Connect the LPG fuel line to the tank service coupling. Make sure the service coupling is clean and free of damage. Also make sure it matches the machine service coupling.

13. Open the tank service valve slowly and check for leaks. If an LPG leak is found, close the service valve immediately and notify the appropriate personnel.

14. If no leaks are found, the engine is ready to start.

1186 MM267 (6--94) 3-11

MAINTENANCE

FUEL FILTER LOCK

The fuel filter lock filters the LPG fuel. The fuel filter lock also stops the flow of LPG fuel to the engine when the engine is not operating.

Replace the fuel filter lock filter pack with the filter pack replacement kit if diminished gas flow indicates the filter is clogged. A drain plug is provided for purging the filter bowl on the older style fuel filter lock. Clean out the bowl when replacing the filter pack.

REGULATOR

The regulator regulates the flow of LPG fuel to the carburetor. If any malfunction is noted, completely disassemble the regulator. Clean all of the parts in alcohol. Inspect all of the parts and replace where needed. Carefully reassemble the regulator with the seal repair kit. Check for proper operation.

CARBURETOR

The carburetor meters fuel to the engine. If any malfunction is noted, completely disassemble the carburetor. Clean all of the parts in alcohol.

ELECTRICAL SYSTEM

BATTERY

The battery provides the engine with starting power. It requires regular maintenance to operate at its best.

If when checking battery specific gravity, one or more battery cells tests lower than the other battery cells, (0.050 or more) the cell is damaged, shorted, or is about to fail.

The battery is a 12 V, 40 A/h at a 20-hour rate. It is located in the engine compartment. When removing battery cables, remove the negative (--) cable before the positive (+) cable.

Do not allow the battery to remain in discharged condition for any length of time. Do not operate machine if batteries are in poor condition or have a charge level below 25%, specific gravity below

1.155.

Clean the top surface and the terminals of the battery periodically. Use a strong solution of baking soda and water. Brush the solution sparingly over the battery top, terminals, and cable clamps. Do not allow any baking soda solution to enter the battery. Use a wire brush to clean the terminal posts and the cable connectors. After cleaning, apply a coating of clear petroleum jelly to the terminals and the cable connectors. Keep the top of the battery clean and dry.

NOTE: Do not take readings immediately after adding water----if the water and acid are not thoroughly mixed, the readings may not be accurate. Check the hydrometer readings against this chart:

1. Park on level surface. Stop the engine and set the machine parking brake.




2. Remove the engine access cover, right side bumper and cover.

3. Observe the position of the clutch plate bolt with no pressure on the clutch handle. It should be approximately in the center of the slot.

4. Pull the clutch handle to tighten the forward propelling belt. The clutch handle should be

0.25 to 0.50 in (7 to 13 mm) from the stationary handle. Observe the position of the clutch plate bolt. It should not touch the end of the slot. If the handle and bolt are in the proper position, skip to step 8; if not, continue with step 5 to readjust forward belt tension.

5. Loosen the forward idler sheave bolt and slide the idler sheave down to tighten the belt (this also increases distance between clutch handle and stationary handle); slide the sheave up to loosen the belt (this also reduces distance between clutch handle and stationary handle).

6. Tighten the idler sheave bolt.

7. Recheck handle and bolt positions. Repeat as necessary to adjust belt tension.

NOTE: After adjusting the forward belt, it may contact the belt guide when engaged causing a whining noise. To stop the noise, bend the guide up out of the belt’s way.

8. Press the clutch reverse handle to tighten the reverse propelling belt. Observe the position of the clutch plate bolt. It should not touch the end of the slot. If the bolt is in the proper position, skip to step 12; if not, continue with step 9 to readjust reverse belt tension.

NOTE: If the reverse belt is too tight, it will require excessive clutch handle pressure to propel machine in the forward direction. It may also cause the machine to creep backward when the handle is released.

MAINTENANCE

9. Loosen the reverse idler sheave bolt and slide the idler sheave to the rear to tighten the belt; slide the sheave forward to loosen the belt.

NOTE: The belts should be loose enough so that when the machine is pushed forward while in neutral, the large sheave on the differential will turn, but the belts remain stationary. This will make the machine easier to push and will reduce current draw.

10.. Tighten the idler sheave bolt.

11. Pull the clutch handle to recheck the position of the clutch plate bolt. Repeat as necessary to adjust belt tension.

12.. Check steering effort. After repairing or replacing drive system parts, effort may increase due to poor alignment. To correct, do the following:

A. Loosen the bearing flanges as well as the split coupling bolts.

B. Snug one split coupling bolt.

C. Align the propelling belts. Check for clearance between the differential and the locking collar.

NOTE: Minimum clearance between differential and sheave is 0.010 in (0.3 mm).

D. While holding belt alignment, pull the shaft away from the differential.

E. Tighten the left bearing flanges. Check for hard rotation of shaft.

F. Tighten the left bearing collars.

G. Pull the short differential shaft away from differential to spread the differential gears.

H. Tighten the right side bearing flange.

Rap on bearing before tightening.

I. Tighten the right bearing collar.

J. Check for free spinning of differential.

6. Close the filter assembly and check the clearance between the filter cover and the hopper. This can be done by placing a 1 in

(25 mm) wide strip of paper between the filter cover and the hopper. When correctly adjusted, the paper will be difficult to pull out. The seal pressure should not be so great that the hopper will not float. Push the hopper down to check -- it should be able to go down and return to its original position.

DUST FILTER

The dust filter filters the air which is drawn up from the main brush compartment by the vacuum fan. It is located inside the dust filter compartment. Shake the excess dust from the filter daily and before emptying hopper. Inspect and clean or replace the dust filter after every 100 hours of operation.

To clean the dust filter use one of the following methods:

D

TAPPING -- Tap the filter gently on a flat surface with the dirty side down. Do not damage the edges of the filter element or the filter will not seat properly in the filter frame.

D AIR -- Blow compressed air, 35 psi (240 kPa) maximum, through the dust filter opposite the direction of the arrows. This may be done with the filter in the machine.

Always wear eye protection when using compressed air.

D

WATER -- Soak the dust filter in a water and mild detergent solution. Rinse the dust filter until it is clean. The maximum water pressure allowable is 40 psi (275 kPa). Air dry the wet dust filter; do not use compressed air.

NOTE: Be sure the dust filter is dry before reinstalling it in the machine.

Machines equipped with the fine particle filter option should vacuum the extra filter clean whenever the standard filter is serviced.
