k k
WARNING
• Never contact the positive (+) terminal and negative (-)
terminal when connecting the cables.
• Always wear protective eyeglasses and rubber gloves
when starting the engine by using the jumper cable.
• Do not bring the normal machine into contact with he
failed machine.
Spark may occur near the battery which generates the
hydrogen gas, and it may explode.
• Connect the correct jumper cables correctly.
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.
(However, do not connect to the work equipment since
the current does not flow well through it.)
• Do not bring the clips in contact with other clips or
with the machine when disconnecting the jumper ca-
ble.
NOTICE
• 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.
• Firmly connect the cables and clips.
• Check that the lock lever is in LOCK position.
• Control levers must be 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.
