WARNING
• 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.

tom of the plug hole, the oil level is appropriate.
If the oil level is low, check it again according to the follow-
ing procedure.
