OPERATION
CHECK ENGINE OIL PAN LEVEL, ADD OIL
Parts and oil are at high temperature immediately after the engine is stopped and may cause serious burns. Wait for the oil
temperature to go down before performing this operation.
1. Open the engine side cover on the right side of the rear portion of the machine.
2. Remove dipstick (G), and wipe the oil off with a cloth.
3. Fully insert dipstick (G) into filler pipe, then remove it.
4. The oil level should be between the marks on dipstick (G).
If the oil level is below the mark, add engine oil through oil filler
(F).
5. If the oil is above the H mark, open drain plug (P) at the rear
right of the machine, drain the excess oil into a container, and
check the oil level again.
6. If the oil level is correct, tighten the oil filler cap securely and
close the engine side cover.

Wait for at least 15 minutes, after stopping the engine, before
checking the oil level.
