FUNCTIONAL
DESCRIPTION
CAUTION:
Always be sure that the machine
is switched off and the portable power pack is
disconnected from the machine before adjusting
or checking function on the machine.
Machine / battery protection system
The machine is equipped with a machine/battery
protection system. This system automatically cuts off
power to the motor to extend machine and battery life.
The machine will automatically stop during operation if
the machine or battery is placed under one of the fol-
lowing conditions:
Overload protection
When the machine or battery is operated in a manner
that causes it to draw an abnormally high current, the
machine automatically stops and the speed indicator
blinks in green. In this situation, turn the machine off
and stop the application that caused the machine to
become overloaded. Then turn the machine on to
restart.
Overheat protection
When the machine or battery is overheated, the
machine stops automatically. When the machine is
overheated, the speed indicator lights up in red. When
the battery is overheated, the speed indicator blinks
in red. Let the machine and battery cool down before
turning the machine on again.
Overdischarge protection
When the battery capacity is not enough, the machine
stops automatically and the speed indicator blinks in
red. In this case, remove the battery from the machine
and charge the battery or change the battery to fully
charged one.
Protections against other causes
Protection system is also designed for other causes that
could damage the machine and allows the machine to
stop automatically. Take all the following steps to clear
the causes, when the machine has been brought to a
temporary halt or stop in operation.
1. Turn the machine off, and then turn it on again to
restart.
2. Charge the battery(ies) or replace it/them with
recharged battery(ies).
3. Let the machine and battery(ies) cool down.
If no improvement can be found by restoring protection
system, then contact your local Makita Service Center.
NOTICE:
If the machine stops due to a cause
not described above, refer to the section for
troubleshooting.
