Leave the engine running at idle for 15 minutes or more
and check the level when the indication of the torque con-
verter oil temperature gauge is at the middle point of the
lowest scale.
• When shipped from plant, etc.
When the indication of the torque converter oil temperature
gauge becomes to the middle point between the lowest
and the second lowest scales due to temperature increase
in the stall condition, run the engine at idle for approxi-
mately 5 minutes and check the oil level.

WARNING
• When checking the oil level, apply the parking brake and fix the front and rear frames using the
frame lock bar.
• Immediately after the engine is stopped, parts and oil are still very hot. Wait for the temperature to
go down, and then start the work.
If ooze of oil is recognized on the axle case, perform the checks.
Place the machine on a level ground before starting the check.
(If the machine is inclined in the right or left, the oil level cannot be checked correctly.)
