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. When the final cable is connected to the
engine block of the failed machine, sparks are generat-
ed. Accordingly, connect it to a point as far from the
battery as possible.
•
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 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 work equipment lock levers and parking brake levers of both machines are in LOCK
position.
•
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 OFF, check that the system operating lamp is not lit, and then turn the battery disconnect
switch key to OFF position before connecting the jumper cable. For the operating method of the
battery disconnect switch, see "BATTERY DISCONNECT SWITCH (3-101)".
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.
1.
Connect the clip of jumper cable (A) to the positive (+) ter-
minal of battery (C) on the failed machine.
2.
Connect the clip at the other end of jumper cable (A) to the
positive (+) terminal of battery (D) on the normal machine.
3.
Connect the clip of jumper cable (B) to the negative (-) ter-
minal of battery (D) on the normal machine.
4.
Turn the battery disconnect switch (S) of the failed ma-
chine to ON position.
