OPERATION
CHECK OIL LEVEL IN ENGINE OIL PAN, 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 hood cover and check the oil level with the
dipstick (G).
2. Take out the dipstick (G) and wipe off the oil with cloth.
3. Fully insert dipstick (G) into filler pipe (F), then remove it.
4. The oil level should be between the H and L marks on the
ENGINE STOPPED side of dipstick (G).
If the oil is below the L mark, add oil through oil filler (F).
5. If the oil level is above the H mark, open the underguard of the
engine, remove drain plug (1), and loosen drain valve (2) to
drain the excessive oil, and then check the oil level again.
6. If the oil level is correct, tighten the handle of the oil filler cap
securely.
REMARK
When checking the oil level after the engine has been operated, wait for at least 15 minutes after stopping the
engine.
If the machine is at an angle, make it horizontal before checking.
The dipstick has the oil level marked on both sides: ENGINE STOPPED for measuring when the engine is
stopped, and ENGINE IDLING for measuring when the engine is idle.
When checking the oil level, stop the engine and check with the ENGINE STOPPED side of the dipstick.
It is also possible to check when the engine is idle, but the following procedure must be used.
• Check that the engine water temperature is in the white range.
• Use the ENGINE IDLING side of the dipstick.
• Remove the oil filler cap.
