OPERATION
STARTING ENGINE
Always check that the safety lock lever is set to the LOCK position, regardless of whether the machine is
working normally or has failed. Check also that all the control levers are at the HOLD or neutral position.
1. Make sure the clips are firmly connected to the battery terminals.
2. Start the engine of the normal machine and keep it to run 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.

the reverse of the order in which they were connected.
1. Remove one clip of booster cable (B) from the engine
block of the problem machine.
2. Remove the other clip of booster cable (B) from the nega-
tive (-) terminal of the normal machine.
3. Remove one clip of booster cable (A) from the positive
(+) terminal of the normal machine.
