PRECAUTIONS FOR OPERATION
SAFETY
2-24
OPERATION 2
CHECKS BEFORE OPERATION
If the checks before starting are not carried out properly, the machine will be unable to display its full performance,
and there is also danger that it may lead to serious personal injury or death.
When carrying out the checks, move the machine to a wide area where there are no obstructions, and pay careful
attention to the surrounding area. Do not allow anyone near the machine.
q
Always wear the seatbelt. There is danger that you may be
thrown out of the operator's seat and suffer serious injury
when the brakes are applied suddenly.
q
Check that the movement of the machine matches the dis-
play on the control pattern card. If it does not match,
replace it immediately with the correct control pattern card.
q
Check the operating condition of the machine, work equip-
ment, arm, boom, travel, and swing system.
q
Check for any problem in the sound of the machine, vibra-
tion, heat, smell, or gauges; check also that there is no
leakage of oil or fuel.
q
If any problem is found, carry out repairs immediately.
PRECAUTIONS WHEN TRAVELING IN FORWARD OR REVERSE AND SWINGING
q
When traveling, drive with sprocket (1) at the rear of the
machine. If sprocket (1) is at the front, the operation of the
travel levers will be the opposite of the actual direction of
travel, so there is a hazard that the machine may travel in
an unexpected direction, leading to serious injury or death.
q
Always lock all the door and windows of the operator's
compartment in position (open or closed).
On jobsites where there is a hazard of flying objects or of
objects entering the operator's compartment, check that all
the door and windows are securely closed.
q
Do not allow anyone apart from the operator to ride on the
machine.
