OPERATION
CHECK OIL LEVEL IN ENGINE OIL PAN, ADD OIL
Immediately after the engine is stopped, its parts and oil are still very hot, and may cause burn injury. Accordingly, wait until they
have cooled down before starting the work.
1. Open the engine side cover on the right side of the machine.
2. Remove dipstick (G), and wipe the oil off with a cloth.
3. Fully insert dipstick (G) into dipstick pipe, then remove it.
4. The oil level should be between H and L marks on ENGINE
STOPPED side of dipstick (G).
If the oil level is below L mark, add oil through oil filler port (F).
5. If the oil is above H mark, remove drain plug (1), loosen drain
valve (2) to drain the excess oil, then check the oil level again.
6. If the oil level is correct, tighten the oil filler cap securely and
close the engine side cover.
REMARK
When checking the oil level after the engine has been operated, wait for at least 15 minutes after stopping the
engine before checking.
If the machine is at an angle make it horizontal before checking.
When adding oil, remove the dipstick form the holder to release the air inside the crankcase.
The dipstick is marked with the levels for "ENGINE STOPPED" on one side and "ENGINE IDLE" on the other
side.
It is also possible to check the oil level with the engine idle, but be sure to remember the following points.
· Check oil when the engine coolant temperature gauge is within the green range.
· Read the dipstick on its reverse side marked with "ENGINE IDLE".
