Change axle oil
WARNING
z When changing the oil, apply the parking brake and secure
the front and rear frames with the safety bar.
z After the engine is stopped, the parts and oil are at high tem-
perature, and may cause burns. Wait for the temperature to
go down before starting the operation.

When the plug is removed, oil may spurt out, so turn it slowly
to release the internal pressure, then remove it carefully.

remove oil filler plug (2) and drain the oil through the hose.
