CHECK OIL LEVEL IN ENGINE OIL PAN, ADD OIL
The parts and oil are at high temperature after the engine is stopped, and may cause serious burns. Wait
for the temperature to go down before starting the operation.
1. Open the engine side cover on the left side of the chas-
sis.
2. Remove dipstick (G) and wipe the oil off with a cloth.
3. Insert dipstick (G) fully in the oil filler pipe, then take it out
again.
4. The oil level should be between the H and L marks on
dipstick (G).
If the oil level is below the L mark, add engine oil through
oil filler (F).
5. If the oil is above the H mark, drain the excess engine oil
from drain plug (P), 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.
