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 is placed under one of the fol-
lowing conditions.

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 indicator lamp
lights up in red. 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.

Overheat protection

When the machine is overheated, the machine stops
automatically and the indicator lamp lights up in red.
Let the machine cool down before turning the machine
on again.

Overdischarge protection

When the battery capacity becomes low, the machine
stops automatically and the indicator lamp lights up in
red. If the machine does not operate even when the
switches are operated, remove the battery from the
machine and charge the battery.
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
