OPERATION
STARTING ENGINE WITH BOOSTER CABLES
When starting the engine with a booster cable, do as follows:
CONNECTING AND DISCONNECTING BOOSTER CABLES
When connecting the cables, never contact the posi-
tive (+) and negative (-) terminals.
When starting the engine with a booster cable, always
wear safety glasses.
Be careful not to let the normal machine and problem
machine contact each other. This prevents sparks
fromgenerating 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 con-
nect 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. To avoid hydrogen explosion,
do not allow the cable ends to contact each other or
the machine.
NOTICE
The size of the booster cable and clip should be suitable for the battry size.
The battry of the normal machine must be the same capacity as that of the engine to be started.
Check the cables and clips for damage or corrosion.
Make sure that the cables and clips are firmly connected.
Check that the safety lock levers and parking brake levers of both machine are in the LOCK position.
Check that each lever is in the NEUTRAL position.
