Safety
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 fol-
lows.
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).
When starting from another machine, do not allow the two
machines to touch.
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.
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.
Always wear safety goggles and rubber gloves when starting
the engine with booster cables.
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.
For details of the starting procedure when using booster
cables, see "Starting engine with booster cable (3-181)".
