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. 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.

Speed adjusting dial
► Fig.5: 1. Speed adjusting dial
The rotating speed can be changed by turning the
speed adjusting dial to a given number setting from 1 to
5. Higher speed is obtained when the dial is turned in
the direction of number 5. And lower speed is obtained
when it is turned in the direction of number 1.
Refer to the table for the relationship between the num-
ber settings on the dial and the approximate rotating
speed.
