OPERATION TROUBLESHOOTING

STARTING ENGINE WITH BOOSTER CABLES
When starting the engine with a booster cable, do as follows:
CONNECTING AND DISCONNECTING BOOSTER CABLES
WARNING
● When connecting the cables, never contact the positive
(+) 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 from
generating near the battery which could ignite the hydro-
gen 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 upper structure 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 a machine that
has been started. To avoid hydrogen explosion, do not
allow the cable ends to contact each other or the
machine.
NOTICE
● The starting system for this machine uses 24 Volts. For
the normal machine, use a 24V battery.
● The size of the booster cable and clip should be suitable
for the battery size.
● The battery 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 lever is raised in the LOCK
position and parking brake applied.
● Check that each lever is in the NEUTRAL position.
