METHOD FOR CHECKING OIL LEVEL IN FINAL DRIVE CASE, ADDING OIL

• Immediately after the engine is stopped, its parts and oil are still very hot and may cause burn in-
jury. Wait for the temperature to go down, and then start 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.
Prepare a handle for the work.
