PRECAUTIONS FOR OPERATION SAFETY
2-26
STARTING WITH BOOSTER CABLE
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.
q When starting with a booster cable, carry out the starting
operation with two workers (one worker sitting in the opera-
tor's seat and the other working with the battery).
q When starting from another machine, do not allow the two
machines to touch.
q When connecting the booster cables, turn the starting
switch OFF for both the normal machine and problem
machine. There is a hazard that the machine will move
when the power is connected.
q Be sure to connect the positive (+) cable first when install-
ing the booster cables. Disconnect the negative (-) cable
(ground side) first when removing them.
q 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.
q Always wear safety goggles and rubber gloves when start-
ing the engine with booster cables.
q 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.
q For details of the starting procedure when using booster
cables, see “STARTING ENGINE WITH BOOSTER
CABLE (3-122)“ in the OPERATION section.
