OPERATION
START ENGINE WITH JUMPER CABLES
k k
• When connecting the cables, never contact the posi-
tive (+) and negative (-) terminals.
• Always wear protective eyeglasses and rubber gloves
when starting the engine by using the jumper cable.
• Be careful not to let the normal machine and failed ma-
chine contact each other.
The sparks caused near the battery could ignite the
hydrogen gas generated from the battery, so be care-
ful not to let it happen.
• Make sure that there is no mistake in the jumper cable
connections. 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 possi-
ble. (However, do not connect to the work equipment
since the current does not flow well through it.)
• When removing the jumper cable, exercise good care
so that the jumper cable clips may not contact each
other, or they contact the chassis.
NOTICE
• The starting system for this machine uses 24 V. Accordingly, the normal machine must be equipped
with a 24 V battery.
• The sizes of the jumper cables and clips should be suitable for the battery size.
• The battery of the normal machine must be the same capacity as that of the failed machine.
• Check the cables and clips for damage or corrosion.
• Make sure that the cables and clips are firmly connected.
• Check that the lock levers and parking brake levers (if equipped) of both machine are in LOCK posi-
tion.
• Check that each lever is in NEUTRAL position.
• To prevent damage of the electric devices of the failed machine, turn the starting switch of the failed
machine to OFF position, and then turn the battery disconnect switch key to OFF position before
connecting the jumper cables. For the operating method of the battery disconnect switch, see "BAT-
TERY DISCONNECT SWITCH (3-121)".
REMARK
If the battery disconnect switch is turned to OFF position, the radio tuning information etc. may be lost. In this
case, set the information again. For details of the caution lamps, see "HANDLE RADIO (3-210)".
Connect jumper cable
Turn the starting switch and battery disconnect switch of the failed machine, and the starting switch of the nor-
mal machine to OFF position.
