METHOD FOR CHANGING THE FRONT AXLE OIL

Immediately after the engine is stopped, its parts and oil are still very hot and may cause burn injury.
Wait until they have cooled down before starting the work.
This operation must be carried out with the machine positioned on level ground and at operating temperature,
so that the oil becomes fluid and can be easily drained, which facilitates the elimination of any suspended solid
particles.
