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 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
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
1
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.
Protections against other causes
NOTICE:
The main power lamp blinks in green and red
alternately when the abnormality occurs in the machine.
In this case, refer to the section for troubleshooting.
Protection system is also designed for other causes that could
damage the machine and allows the machine to stop automati-
cally. Take all the following steps to clear the causes, when the
machine has been brought to a temporary halt or stop in operation.
