165.1 STARTING ENGINE WITH BOOSTER CABLE
When starting the engine with a booster cable, do as follows:
Precautions when connecting and disconnecting booster cable
A
WARNING
When connecting the cables, never contact the positive @
and negative 0 terminals.
When starting the engine with a booster cable, always wear
safety glasses.
Be careful not to let the normal machine and problem ma-
chine contact each other. This prevents sparks from generat-
ing near the battery which could ignite the hydrogen gas
given off by the battery. If hydrogen gas explodes, it could
cause serious injury.
Make sure that there is no mistake in the booster cable
connections. The final connection is to the revolving frame,
but sparks will be generated when this is done, so connect
to a place as far as possible from the battery. (However, avoid
connecting the cable to the work equipment, as conduction
is poor.)
Use care when removing the cables from the machine that
has been started. Do not allow the cable ends to contact each
other or the machine, to avoid hydrogen explosion.
NOTICE
l The size of the booster cable and clip should be suitable for the
battery size.
l The battery of the normal machine must be the same capacity
as that of the engine to be started.
l Check the cables and clips for damage or corrosion.
