NOTE: The indicator lamp for remaining battery
capacity is just for a reference. The actual battery
capacity may differ depending on the usage condi-
tions or ambient temperature.
NOTE: While the machine is in operation, the indicator
lamp does not light up even if you press the check button.
NOTE: The lamp automatically goes off after a few seconds.
Machine/battery protection system
The machine is equipped with a machine/battery protec-
tion 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 following conditions:
Overload protection
When the 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.
NOTE: The main power lamp also blinks in green
and the machine automatically stops if the machine
is operated for a long time continuously. In this case,
release the switch trigger and return the control lever
fully, and then pull the switch trigger again to restart
the machine.
Overheat protection
When the machine or battery 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.

If the machine stops due to a cause
not described above, refer to the section for
