Overload Protection; Overheat Protection - Makita HR005G Betriebsanleitung

NOTE: Depending on the conditions of use and the
ambient temperature, 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 sys-
tem. This system automatically cuts off power to the
motor to extend tool and battery life. The tool will auto-
matically stop during operation if the tool or battery is
placed under one of the following conditions:

Overload protection

When the tool or battery is operated in a manner that
causes it to draw an abnormally high current, the tool
automatically stops without any indication. In this sit-
uation, 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 or battery is overheated, the tool stops
automatically and the lamp blinks. In this case, let the
tool and 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.

NOTE: Soft no-load rotation function
When the speed adjusting dial is set to "3" or higher,
the tool automatically reduces the speed at no-load to
reduce the vibration under no-load.
Once operation starts with a bit against concrete,
blows per minute increase and reach the numbers as
