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
Always wear safety goggles and rubber gloves when start-
ing 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 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 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.

for at least 3 minutes after turning the starting switch OFF,
then turn the battery isolator switch OFF before connecting
or removing the booster cable.

ing the booster cables. Disconnect the negative (-) cable
(ground side) first when removing them.

booster cable clips touch each other or to let the clips touch
the machine.
