Overload Protection; Overheat Protection; Overdischarge Protection - Makita DCU180 Instruction Manual

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 cartridge is under one of the follow-
ing conditions. A short beep sound is emitted before the
machine stops automatically. The battery indicators and
LED indicators blink while the beep sound is emitted.

Overload protection

When the machine is operated in a manner that causes
it to draw an abnormally high current, the machine auto-
matically stops without any indication. In this situation,
turn the machine off and remove the cause of overload,
and then turn the machine on to restart.

Overheat protection

When the machine is overheated, the machine stops
automatically. Let the machine cool down before turning
the machine on again. The overheat protection is likely
to work under high temperature environment.

Overdischarge protection

When the battery capacity becomes low, the machine
stops automatically. If the machine does not operate
even when the switches are operated, remove the
battery cartridge and charge it.
