SAFETY

TWO WORKERS FOR MAINTENANCE WHEN ENGINE IS RUNNING

To prevent personal injury, do not perform maintenance with the engine running. If maintenance must be performed
with the engine running, perform the operation with at least 2 workers and observe the following.
1 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 performing 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, fan belt,
or other rotating parts. There is danger that they may contact
the rotating parts and break or be sent flying.
Set work equipment lock lever (1) and parking brake lever (2) to
LOCK position (L) to prevent the work equipment 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.

INSTALLING, REMOVING, OR STORING ATTACHMENTS

Appoint a leader before starting removal or installation
operations for attachments.
Place attachments that have been removed from the machine in
a stable condition so that they do not fall. And take steps to
prevent unauthorized persons from entering the storage area.
