Check transmission oil level, add oil
WARNING
The parts and oil are at high temperature immediately after the
engine is stopped, and may cause burns. Wait for the tempera-
ture to go down before starting the work.
Carry out this procedure if there is any sign of oil on the trans-
mission case, or if there is oil mixed with the cooling water.
1. Start the engine and run it at low idling for at least 5 minutes.
2. Open the cap of oil filler port (F), remove dipstick (G), and
wipe the oil off with a cloth.
3. Insert dipstick (G) fully in the oil filler pipe (F), then take it out
again.
4. 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).
5. If the oil is above the H mark, remove cover (1) under the
machine, drain the excess oil from drain plug (P), then check
the oil level again.
6. If the oil level is correct, insert dipstick (G) in the dipstick
guide, then tighten the cap.
