8.4.4 STARTING ENGINE WITH BOOSTER CABLE
When starting the engine with a booster cable, do as follows.
[1] PRECAUTIONS FOR CONNECTING AND DISCONNECTING BOOSTER CABLE
• When connecting the cables, never contact the positive
(+) and negative (-) terminals.
• When starting the engine with a booster cable, always
wear safety glasses and rubber gloves.
• Be careful not to let the normal machine and problem
machine contact each other. This prevents sparks from
generating near the battery which could ignite the
hydrogen gas given off by the battery. If hydrogen gas
explodes, it could cause serious injury.
• Be careful not to make a mistake when connecting a
booster cable.
In the last connection (to the upper structure frame), a spark will be caused, connect the cable
to a spot as far away from the battery as possible. (Avoid the crane, however, because it is not
a good conductor)
• When removing the booster cable, exercise good care so that the booster cable clips may not
contact each other, or they contact the chassis.
• The size of the booster cable and clip should be suitable for the battery size.
• The battery of the normal machine must be the same capacity as that of the engine to be
started. The starting system for this machine uses 24 V. For the normal machine, also use a 24
V battery.
• Check the cables and clips for damage or corrosion.
• Make sure that the cables and clips are firmly connected.
• Check that the lock levers of both machines are in the LOCK position.
• Check that each lever is in the NEUTRAL position.
[2] BOOSTER CABLE CONNECTION
Connect the booster cable as follows, in the order of the numbers marked in the diagram.
1. Keep the starter switch of the normal machine and
problem machine in the OFF position.
2. Connect the clip of booster cable (A) to the positive (+)
terminal of battery on the problem machine.
3. Connect the clip at the other end of booster cable (A) to
the positive (+) terminal of battery on the normal
machine.
4. Connect the clip of booster cable (B) to the negative (-)
terminal of battery on the normal machine.
5. Connect the other clip of booster cable (B) to the upper
structure frame of the problem machine.
