OPERATION

Starting Engine with Booster Cables 3
When starting the engine with a booster cable, do as follows:
Connecting and Disconnecting Booster Cables
WARNING
q
When connecting the cables, never contact the posi-
tive (+) and negative (-) terminals.
q
When starting the engine with a booster cable, always
wear safety glasses.
q
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.
q
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 possi-
ble. (Avoid the work equipment, however, because it is
not a good conductor)
q
When removing the booster cable, exercise good care
so that the booster cable clips may not contact each
other, or they contact the chassis.
NOTICE
q
The starting system for this machine uses 24V. For the normal machine, also use a 24V battery.
q
The size of the booster cable and clip should be suitable for the battry size.
q
The battery of the normal machine must be the same capacity as that of the engine to be started.
