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
following 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.
Switching the battery cartridge

Up to two battery cartridges can be installed in the
battery box, although the machine uses one battery
cartridge for operation. Before operating the machine,
select the battery cartridge used for operation by press-
ing the number on the battery selection switch.

the battery box, be sure to select the battery box in
which the battery cartridge is installed.
