•
Never connect the positive (+) and negative (-) termi-
nals when connecting the cables.
•
Wear the protective eyeglasses and rubber gloves al-
ways when starting the engine by using the jumper ca-
ble.
•
Do not bring the normal machine into contact with the
failed machine.
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 disconnecting the jumper cable, take care not to
bring the clips in contact with each other or with the
machine.
NOTICE
•
The starting system for this machine uses 24 V. Accordingly, the normal machine must be equipped
with a 24 V power supply.
•
Use the jumper cables and clips that corresponds 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 machines are in LOCK po-
sition.
•
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 (3-113)".
REMARK
If the battery disconnect switch is turned to OFF position, the radio tuning information etc. may be lost. In this
case, set it again by referring to "HANDLING RADIO (3-236)".
PROCEDURE FOR CONNECTING 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.
