Battery Protection System - Makita DFL651F Instruction Manual

Battery protection system

The tool is equipped with a battery protection system.
This system automatically cuts off power to the motor to
extend battery life.
The tool will automatically stop during operation if the
tool and/or battery are placed under one of the following
conditions:
• Overloaded:
The tool is operated in a manner that causes
it to draw an abnormally high current.
In this situation, turn the tool off and stop the
application that caused the tool to become
overloaded. Then turn the tool on to restart.
If the tool does not start, the battery is over-
heated. In this situation, let the battery cool
before turning the tool on again.
• Low battery voltage:
The remaining battery capacity is too low
and the tool will not operate. In this situation,
remove and recharge the battery.
NOTE: The overheat protection works only with a
battery cartridge with a star marking.
