6.1.1 Charge Battery
Be sure to read the operation manual of the battery charger to
know if it is applicable, before using it.
Disconnect the cable between battery and the unit, and
charge the battery with a 12V battery charger. Do not charge
two batteries at the same time.
Be sure not to connect (+) and (–) terminals backwards.
6.1.2 How to Use Booster Cable
If a booster cable has to be used or when cables are connected at battery replacement, be careful not to
connect (+) and (–) terminals backwards. Such a wrong-connection will cause spark and damage each
component.
<Procedure for using a booster cable>
① Stop the engine.
② Connect one end of the (+) cable to the (+) terminal
of the machine battery.
③ Connect the other end of the (+) cable to the (+)
terminal of the external battery.
④ Connect one end of the (–) cable to the (–) terminal
of the external battery.
⑤ Connect the other end of the (–) cable to the engine
block of the machine.
⑥ Start up the engine.
⑦ Disconnect the booster cable by following the
procedure back in the reverse order.
