Two Workers for Maintenance when Engine is Running

To prevent injury, do not carry out maintenance with the engine
running. If maintenance must be carried out with the engine
running, carry out the operation with at least two workers and do as
follows.
One worker must always sit in the operator's seat and be ready
to stop the engine at any time. All workers must maintain
contact with the other workers.
Set safety lock lever (1) to the LOCK position.
When carrying out operations near the fan, fan belt, or other
rotating parts, there is a hazard of being caught in the parts, so
be careful not to come close.
Do not touch any control levers. If any control lever must be
operated, give a signal to the other workers to warn them to
move to a safe place.
Never drop or insert tools or other objects into the fan or fan belt.
Parts may break or be sent flying.
