Starting Engine With Booster Cables - Komatsu PC130-7 Operation & Maintenance Manual

OPERATION

Starting Engine with Booster Cables

When starting the engine with a booster cable, do as follows:
Connecting and Disconnecting Booster Cables
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, so connect
the cable to a spot as far away from the battery as pos-
sible. (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.
q Check the cables and clips for damage or corrosion.
q Make sure that the cables and clips are firmly connected.
q Check that the safety lock levers and parking brake levers of both machine are in the LOCK position.
q Check that each lever is in the NEUTRAL position.
