BEFORE OPERATING MACHINE
If checks are not carried out properly after starting the engine, it may result in a delay in discovering
abnormalities in the machine, and this may lead to personal injury or damage to the machine.
Carry out the checks in an open area where there are no obstructions. Do not let anyone near the machine
when carrying out the checks.
•
Check the operating condition of the equipment, and the actuation of the bucket, boom, and
travel systems.
•
Check the machine for any abnormal noise, vibration, heat, smell, or abnormality with the
gauges. Check also for leakage of air, oil, and fuel.
•
If any abnormality is found, repair the problem immediately. If the machine is used without
repairing the problems, it may lead to unexpected injury or failure.
•
Clear all personnel from directly around machine and from the area.
•
Clear all obstacles from the machine's path. Beware of hazards.
•
Be sure that all windows are clean. Secure the doors and the windows in the open position or in
the shut position.
•
Adjust the rear view mirrors for best visibility close to the machine. Make sure that the horn, the
travel alarm (if equipped), and all other warning devices are working properly.
•
Fasten the seat belt securely.
•
Warm up the engine and hydraulic oil before operating machine.
•
Before moving the machine, check the position of undercarriage. The normal travel position is
with idler wheels to the front under the cab and the drive sprockets to the rear. When the
undercarriage is in the reversed position, the travel controls must be operated in opposite
directions.
