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 bat-
tery cartridge is under one of the following conditions.
A short beep sound or long beep sound is emitted
before the machine stops automatically. The battery
indicators and lamps on the control panel blink while the
beep sound is emitted.
NOTE: To cancel the beep sound, release the switch
trigger and pull the brake lever.

Overload protection

When the machine/battery is operated in a manner
1
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 such as reducing the loaded
objects. 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.

Overdischarge protection

When the battery capacity is not enough, the main power
lamp and the corresponding battery indicator blink in red.
In this case, switch the battery cartridges, or change the
battery cartridges to fully charged ones, or remove the
battery cartridges from the machine and charge them.
NOTE: The main power lamp blinks in red when the
battery is overheated.
