METHOD FOR CHANGING OIL IN FINAL DRIVE CASE
• Immediately after the engine is stopped, its parts and oil are still very hot and may cause burn in-
jury. Accordingly, wait until they have cooled down before starting the work.
• If there is remaining pressure inside the case, the oil or plug may jump out. Loosen the plug slowly
to release the pressure.
• Do not stand in front of the plug when you loosen the plug.
