WARNING
Immediately after the engine is stopped, its parts and oil are still very hot and may cause burn injury.
Wait for the temperature to go down, and then start the work.
Perform this operation when ooze of oil on the transmission case is recognized or when oil in the coolant is rec-
ognized.
1.
Stop the engine.
REMARK
You cannot measure the exact oil level until 12 hours elapses after the engine is stopped because the oil
remains in various parts.
2.
Set the frame lock bar to LOCK position (L).
3.
Remove the cap of oil filler port (F).
4.
Check the oil level with sight gauge (G).
The oil level is correct if it is within range (A) at upper part
of sight gauge (G).
