“FULL” mark on the dipstick. Add the oil slowly and
check the level often during this process. Do not
overfill.

Changing the Oil Filter
Replace the oil filter every 100 operating hours or yearly,
whichever occurs first.
1. Drain the oil from the engine; refer to Changing and
Draining the Oil, page 22.
2. Remove the existing oil filter (Fig. 20). Apply a light
coat of clean oil to the new filter gasket.
3. Screw the filter on until gasket contacts mounting plate,
then tighten filter an additional 1/2 to 3/4 turn further.
Do not overtighten.
4. Fill the crankcase with the proper type of new oil; refer
to Servicing the Engine Oil, page 22.
5. Start and run the engine to check for leaks.
6. Stop the engine and recheck the oil level. Add oil if
necessary.
Cleaning the Engine Cooling
Areas
Clean the rotating screen, cooling fins, and external
surfaces of the engine every 100 hours of operation or more
often under extremely dusty and dirty conditions.
Important Operating the engine with a blocked
rotating screen, dirty or plugged cooling fins or cooling
shrouds removed, will cause engine damage due to
overheating.
Important Never clean the engine with pressurized
water because water could contaminate the fuel system.
Servicing the Air Cleaner
Check the air cleaner body for damage which could
possibly cause an air leak. Replace a damaged air cleaner
body.
Ensure that the cover is sealing around the air cleaner body.
Air Cleaner Filter: Inspect after every 100 operating hours;
replace after every 200 hours or sooner if dirty or damaged.
Note: Service the air cleaner more frequently (every few
hours) if operating conditions are extremely dusty or sandy.
Removing the Filter Element
1. Park the machine on a level surface, set the parking
brake, turn the ignition off, and remove the key.
2. Raise the bed and secure it with the prop rod.
3. Release the latches securing the air cleaner cover to the
air cleaner body. Separate the cover from the body.
Clean the inside of the air cleaner cover (Fig. 21).
4. Gently slide the filter out of the air cleaner body to
reduce the amount of dust dislodged (Fig. 21). Avoid
knocking the filter against the air cleaner body.
5. Inspect the filter and discard it if it is damaged.
