Two workers for maintenance when engine is running 0.
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.
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.
Never drop or insert tools or other objects into the fan or fan
belt. Parts may break or be sent flying.
Set safety lock lever (1) to the LOCK position to prevent the
work equipment from moving. Then pull parking brake lever
(2) to the position to prevent the machine from moving.
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.
