Battery protection system

The machine is equipped with a battery protection
system. This system automatically cuts off power to the
motor to extend battery life.
The machine will automatically stop during operation if
the machine and/or battery are placed under one of the
following conditions:
Overloaded:
The machine is operated in a manner that causes it to
draw an abnormally high current.
In this situation, turn the machine off and stop the appli-
cation that caused the machine to become overloaded.
Then turn the machine on to restart.
If the machine does not start, the battery is overheated.
In this situation, let the battery cool before turning the
machine on again.
Low battery voltage:
The remaining battery capacity is too low and the
machine will not operate. If you turn the machine on,
the motor runs again but stops soon. In this situation,
remove and recharge the battery.
