Machine / battery protection system
The machine is equipped with a machine/battery

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 or battery is operated in a manner
that causes it to draw an abnormally high current, the
machine automatically stops and the main power lamp
of the machine blinks in green. 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 or battery is overheated, the
machine stops automatically. When the machine is
overheated, the main power lamp of the machine
lights up in red. When the battery is overheated, the
main power lamp of the machine blinks in red. Let
the machine and battery cool down before turning the
machine on again.
Overdischarge protection
When the battery capacity is not enough, the machine
stops automatically and the main power lamp of the
machine blinks in red. In this case, remove the battery
from the machine and charge the battery or change the
battery to fully charged one.
