MAINTENANCE
11
(1) Change engine oil every 25 hours when used under heavy load or in high ambient
temperatures.
(2) Clean more often under dusty conditions or when airborne debris is present. Replace air
cleaner parts, if very dirty.
(3) These items should be serviced by your servicing dealer unless you have the proper tools
and are mechanically proficient. Refer to manual for service procedures.
Failure to follow this maintenance schedule could result in nonwarrantable failures.
CAUTION:
Used oil is a hazardous waste product. Dispose of used oil properly. Do not
discard with household waste. We suggest you take used oil in a sealed container to your local
recycling center or service station for reclamation.
CHANGE ENGINE OIL
Drain the used oil while the engine is warm. Warm oil drains quickly and completely.
1. Place a suitable container below the engine to catch the used oil, and then remove the filler
cap/dipstick, the drain bolt and sealing washer.
2. Allow the used oil to drain completely, and then reinstall the drain bolt and sealing washer,
and tighten it securely.
3. With the engine in a level position, fill to the upper limit mark on the dipstick with the
recommended oil.
4. Reinstall the oil filler cap/dipstick securely.
Running the engine with a low oil level can cause engine damage.
