Starting With Booster Cables - Komatsu D155A-6 Operation & Maintenance Manual

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 two workers (one 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
the 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 procedure when starting the machine using a
booster cable, see "STARTING ENGINE WITH BOOSTER
CABLE (PAGE 3-180)".
