SAFETY
TWO WORKERS FOR MAINTENANCE WHEN ENGINE IS RUNNING
To prevent accident, do not perform maintenance with the engine running. When it is necessary to perform the
maintenance with the engine running, always observe the following.
• 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.
• Rotating parts such as the fan, fan belt are dangerous that
they may easily catch a body part or an object someone
wears. Be careful not to come close to the rotating part.
• Never drop or insert tools or other objects into the fan, fan
belt, or other rotating parts. They may contact the rotating
parts and break, and be scattered. It is dangerous.
• If the automatic active regeneration of KDPF starts during
maintenance work, surroundings of KDPF become high
temperature.
When performing the maintenance work, stop the regener-
ation of KDPF.
• Set work equipment lock lever (1) and parking brake lever
(2) to LOCK positions (L) to prevent the work equipment
from moving.
• Do not touch the control levers. When it is necessary to
operate the control levers, always give a signal to your fel-
low workers to evacuate them to a safe place.
PRECAUTIONS WHEN INSTALLING, REMOVING, OR STORING ATTACHMENTS
• Appoint a leader before starting removal or installation operations for attachments.
• Place attachments that have been removed from the ma-
chine in a stable condition so that they do not fall. And take
steps to prevent unauthorized persons from entering the
storage area.
PRECAUTIONS FOR WORKING AT HIGH PLACES
When working at high places, use a step ladder or other stand to ensure that the work can be performed safely.
There is a danger falling from high place that can lead to serious personal injury or death.
