Reversing switch action

NOTE: Depending on the conditions of use and the
ambient temperature, the indication may differ slightly
from the actual capacity.
CAUTION: Always check the direction of
rotation before operation.
Tool / battery protection system
CAUTION: Use the reversing switch only after
the tool comes to a complete stop. Changing the
direction of rotation before the tool stops may dam-
age the tool.
CAUTION: When not operating the tool,
always set the reversing switch lever to the neu-
tral position.
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 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.
This tool has a reversing switch to change the direction
of rotation. Depress the reversing switch lever from the
A side for clockwise rotation or from the B side for coun-
terclockwise rotation.
When the reversing switch lever is in the neutral posi-
tion, the switch trigger cannot be pulled.
Speed change
Overheat protection
► Fig.6: 1. Speed change lever
When the tool is overheated, the tool stops automati-
cally and the lamp blinks. In this situation, let the tool/
battery cool before turning the tool on again.
Overdischarge protection
CAUTION: Always set the speed change lever
fully to the correct position. If you operate the
tool with the speed change lever positioned halfway
between the "1" side and "2" side, the tool may be
damaged.
When the battery capacity is not enough, the tool stops
automatically. In this case, remove the battery from the
tool and charge the battery.
CAUTION: Do not use the speed change lever
while the tool is running. The tool may be damaged.
