Machine / battery protection system
The machine is equipped with the 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 following conditions.
- Overload protection : When the machine is operated in a manner that causes it to draw an abnormally high current,
the machine automatically stops without any indication. In this situation, turn the machine off and stop the applica-
tion that caused the machine to become overloaded. Then turn the machine on to restart.
- Overdischarge protection : When the battery capacity becomes low, the machine stops automatically. If the
machine does not operate even when the switches are operated, remove the battery cartridge from the machine
and charge it.
