Keep the starting switch of the normal machine and problem
machine at the OFF position.
Connect the booster cable as follows, in the order of the numbers
marked in the diagram.
1. Make sure that the starting switches of the normal machine
and problem machine are both at the OFF position.
2. Connect one clip of booster cable (A) to the positive (+) termi-
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.

STARTING THE ENGINE
Always check that the safety lock lever is raised in the
●
LOCK position, regardless of whether the machine is
working normally or has failed. Also check that all the
control levers are at the HOLD or neutral position.
In certain conditions it may be possible for the safety
●
lock lever to contact the left hand arm rest on the opera-
tor seat.
to avoid this, always ensure that the left hand arm rest is
stowed in the fully up position before operating the
safety lock lever.
1. Make sure the clips are firmly connected to the battery termi-
nals.
2. Start the engine of the normal machine and keep it to running
at high idling speed.
3. Turn the starting switch of the problem machine to the START
position and start the engine. If the engine doesn't start at
first, try again after 2 minutes or so.
BOOSTER CABLE DISCONNECTION
After the engine has started, disconnect the booster cables in the
reverse order in which they were connected.
1. Remove one clip of booster cable (B) from the upper structure
of the problem machine.
2. Remove the other clip of booster cable (B) from the negative
(-) terminal of the normal machine.
3. Remove one clip of booster cable (A) from the positive (+) ter-
minal of the normal machine.
