BE READY FOR PROBLEMS
• Inspect and maintain the machine thoroughly to
prevent problems before they arise.
• If you detect a problem with the machine, stop
operating it immediately, make sure conditions
are safe, and report to the manager.
• Appoint personnel in advance to take
responsibility for measures to prevent
secondary accidents.
• Never operate the machine if fuel or hydraulic
oil is leaking from it. Report the issue to the
manager, and ensure that any leaks have been
completely repaired before using the machine.
This machine uses diesel fuel. Be especially
careful to check for fuel leaks.
• Before leaving the machine, lower the hoisted
load to the ground, turn off the engine, and
remove the starter key.
TEMPORARY STORAGE WHEN A PROBLEM
IS FOUND
If the machine is temporarily stored awaiting
maintenance after a problem has been found, the
following measures should be taken to notify all
personnel that the machine is out of use due to a
failure:
• Place a warning tag on the control levers and
other applicable parts. Clearly indicate the
details of the problem, the name and contact
information of the storage manager, and the
length of time in storage.
• Make sure the machine cannot be moved (e.g.,
by placing chocks in the crawler tracks).

WEAR PROTECTIVE EQUIPMENT AND
SUITABLE WORK CLOTHING
• Always wear a helmet, safety shoes, and safety
belt.
