under high pressure.
In this condition, if the cap is removed, or the oil or water are drained, or the filters
are replaced, it may result in burns or other injury. Wait for the temperature to go
down, then carry out the inspection and maintenance in accordance with the
procedures given in this manual.

ROTATING FAN AND BELT

Keep away from rotating parts and be careful not to let anything get caught in them.

If your body or tools touch the fan blades or fan belt, they may be cut off or sent flying,
so never touch any rotating parts.

•
Always put oil drained from your machine in containers. Never drain oil directly on
the ground.
