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 main power
lamp 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 is overheated, the machine stops
automatically and the main power lamp lights up in red.
In this case, let the machine and battery cool before
turning the machine on again.
NOTE: The main power lamp blinks in red when the
battery is overheated.

Overdischarge protection

When the battery capacity is not enough, the machine
stops automatically and the main power lamp 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.
