Operation
Check oil level in engine oil pan, add oil
WARNING
Engine parts and oil are at high temperature immediately after
the engine is stopped, and may cause serious burns. Wait for
the temperature to go down before starting the operation.
1. Stop the engine and wait for the temperature at all parts to
go down.
2. Open the inspection cover of the right side at the rear of the
machine.
3. Take out the dipstick (G) and wipe off the oil with cloth.
4. Completely insert dipstick (G) fully in the oil filler pipe (F),
then take it out again.
5. The oil level should be between the H and L marks on dip-
stick (G).
If the oil level is below the L mark, add oil through oil filler
(F).
The dipstick has level markings on both sides. One side
gives the levels for measuring when the engine is stopped
(ENGINE STOPPED) and the other side gives the levels for
when the engine is idling (ENGINE IDLING).
When measuring the oil level, measure with the engine
stopped and use the side of the dipstick marked "ENGINE
STOPPED".
6. If the oil is above the H line, open drain valve (P), drain the
excess engine oil, then check the oil level again.
7. If the oil level is correct, tighten oil filler cap (F) securely and
close the inspection window.
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.
REMARK
Checking the oil level with the engine idling may be allowed, if
the following precautions are thoroughly satisfied:
Check that the engine water temperature gauge shows
green range.
Use the side of the dipstick marked "ENGINE IDLING".
Remove the oil filler cap.
