Engine Oil
Maintain the engine oil at the proper level to ensure a properly func-
tioning engine, and change the oil and oil filter every 100 hours or
every six months, whichever comes first. Dirt and metal particles col-
lect in the oil, and oil loses its lubricative quality if used too long.
Suggested break-in oil change is at 25 hours, or one month,
whichever comes first. Severe use operation requires more frequent
service. Severe use includes continuous duty in dusty or wet condi-
tions, and cold weather operation. NOTE: Severe use/cold weather
operation is when all operating is at below 10°F and/or when operat-
ing between 10°F and 30°F if most trips are slow speed and less
than five miles. Always change the oil filter when changing oil.
Oil Check
The engine oil can be checked and/or refilled by folding the bottom
seat cushion up and forward exposing the engine.
1. Position the vehicle on a level surface.
2. Start the engine and let it idle for 20 - 30 seconds.
3. Stop the engine and fold the seat forward.
4. Remove the dipstick and wipe it clean with a clean cloth.
5. Replace the dipstick completely into the engine.
6. Remove the dipstick and check to see that the oil level is
between the full and add marks. Add oil if necessary. Do not over-
fill.
NOTE: A rising oil level between checks in cool weather driving can indi-
cate moisture collecting in the crankcase. If the oil level is above the full
mark, change the oil.
