Overload Protection; Overheat Protection - Makita DTD172 Manual De Instrucciones

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 battery is operated in a manner that causes it
to draw an abnormally high current, the tool stops auto-
matically. 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 and the lamp blinks. 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.
