Starting engine with booster cable
When starting the engine with a booster cable, do as follows:
Precautions when connecting and disconnecting booster
cable
WARNING
z When connecting the cables, never contact the positive (+)
and negative (-) terminals.
z When starting the engine with a booster cable, always wear
safety glasses and rubber gloves.
z Be careful not to let the normal machine and problem
machine contact each other. This prevents sparks from gen-
erating near the battery which could ignite the hydrogen gas
given off by the battery.
z Make sure that there is no mistake in the booster cable con-
nections. The final connection is to the engine block of the
problem machine, but sparks will be generated when this is
done, so connect to a place as far as possible from the bat-
tery.
z
When disconnecting the booster cable, take care not to bring
the clips in contact with each other or with the machine body.
NOTE
z The size of the booster cable and clip should be suitable for
the battery size.
z The battery of the normal machine must be the same capac-
ity as that of the engine to be started.
z Check the cables and clips for damage or corrosion.
z Make sure that the cables and clips are firmly connected.
z Check that the work equipment lock levers and parking
brake levers of both machines are in the LOCK position.
z Check that each lever is in the NEUTRAL position.
