SAFETY
STARTING ENGINE 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.
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)".
