Overload Protection; Overheat Protection; Overdischarge Protection - Makita DFT024F Instruction Manual

NOTE: Depending on the conditions of use and the ambient tem-
perature, the indication may differ slightly from the actual capacity.
NOTE: The first (far left) indicator lamp will blink when
the battery protection system works.
Tool / battery protection system
The tool is equipped with a tool/battery protection system. This
system automatically cuts off power to the motor to extend tool and
battery life. The tool will automatically stop during operation if the
tool or battery is placed under one of the following conditions:

Overload protection

When the tool/battery is operated in a manner that causes it to
draw an abnormally high current, the tool stops automatically. 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.

Overheat protection

When the tool/battery is overheated, the tool stops automatically. In
this situation, let the tool/battery cool before turning the tool on again.

Overdischarge protection

When the battery capacity is not enough, the tool stops automatically.
In this case, remove the battery from the tool and charge the battery.
