PRECAUTIONS FOR OPERATION

STARTING WITH BOOSTER CABLES

If any mistake is made in the method of connecting the booster
cables, it may cause the battery to explode, so always do as
follows.
Always wear safety goggles and rubber gloves when starting
the engine with booster cable.
When connecting a normal machine to a problem machine with
booster cables, always use a normal machine with the same
battery voltage as the problem machine.
When starting with a booster cable, carry out the starting
operation with 2 workers (1 worker sitting in the operator's seat
and the other working with the battery).
When starting from another machine, do not allow the two
machines to touch.
When connecting the booster cables, turn the starting switch to
OFF position for both the normal machine and problem
machine. There is a hazard that the machine will move when the
power is connected.
Be sure to connect the positive (+) cable first when installing the
booster cables. Disconnect the negative (-) cable (ground side)
first when removing them.
When removing the booster cables, be careful not to let the booster cable clips touch each other or to let the clips
touch the machine.
For details of the starting procedure when using booster cables, see "Starting Engine with Booster Cables (PAGE
3-199)" in the OPERATION section.

OPERATION

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.
Always wear the seat belt. There is danger that you may be
thrown out of the operator's seat and suffer serious injury when
the brakes are applied suddenly.
Check that the movement of the machine matches the display
on the control pattern card. If it does not match, replace it
immediately with the correct control pattern card.
Check the operating condition of the machine, work equipment,
arm, boom, travel, and swing system.
Check for any problem in the sound of the machine, vibration,
heat, smell, or gauges; check also that there is no leakage of oil
or fuel.
If any problem is found, carry out repairs immediately.
