Precautions when connecting and disconnecting booster
cable
When connecting the cables, never contact the positive
G
(+) and negative (-) terminals.
When starting the engine with a booster cable, always
G
wear safety glasses.
Be careful not to let the normal machine and problem
G
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
G
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 equip-
ment, as conduction is poor.)
Use care when removing the cables from the machine
G
that has been started. Do not allow the cable ends to con-
tact each other or the machine, to avoid hydrogen explo-
sion.
NOTICE
The size of the booster cable and clip should be suitable
G
for the battery size.
The battery of the normal machine must be the same
G
capacity as that of the engine to be started.
Check the cables and clips for damage or corrosion.
G
Make sure that the cables and clips are firmly connected.

marked in the diagram.

nal of the problem machine.
3. Connect the other clip of booster cable (A) to the positive (+)
terminal of the normal machine.
4. Connect one clip of booster cable (B) to the negative (-) termi-
nal of the normal machine.
