Overload Protection; Overheat Protection; Overdischarge Protection - Makita DWR180 Instruction Manual

Tool / battery protection system
The tool is equipped with a tool/battery protection sys-
tem. This system automatically cuts off the power 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

This protection works when the tool is operated in a
manner that causes it to draw an abnormally high cur-
rent. In this situation, turn the tool off and stop the appli-
cation that caused the tool to become overloaded. Then
turn the tool on to restart.

Overheat protection

When the tool is overheated, the tool stops automat-
ically and the lamp starts blinking. In this situation,
let the tool and battery cool before turning the tool on
again.

Overdischarge protection

This protection works when the remaining battery
capacity gets low. In this situation, remove the battery
from the tool and charge the battery.
