STARTING ENGINE WITH BOOSTER CABLES 2
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
operator's seat and the other working with the battery).
q
When starting from another machine, do not allow the two
machines to touch.
q
Before connecting the additional cables, make sure that
both the starter key and the battery main switch are turned
to OFF.
q
Be sure to connect the positive cable (+) first and then the
negative or earth cable (–) when connecting the booster
cables. Disconnect first the negative or earth (–) cable and
then the positive cable (+) after the start.
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 glasses and rubber gloves when
starting 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 with booster cables (3-195)".
