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 automatically stop during operation if the
tool or battery are placed under one of the following
conditions. In some conditions, the indicator lights up.

Overload protection

When the tool is operated in a manner that causes it to
draw an abnormally high current, the tool automatically
stops without any indications. 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 for tool
When the tool is overheated, the tool stops automati-
cally and the battery indicator shows following state. In
this situation, let the tool cool before turning the tool on
again.

Reversing switch action
CAUTION:
• Always check the direction of rotation before
operation.
• Use the reversing switch only after the tool
comes to a complete stop. Changing the direc-
tion of rotation before the tool stops may dam-
age the tool.
► Fig.7: 1. Reversing switch lever
This tool has a reversing switch to change the direc-
tion of rotation. Move the reversing switch lever
to the position (A side) for clockwise rotation or
the position (B side) for counterclockwise rotation.
When the reversing switch lever is in the neutral posi-
tion, the switch trigger cannot be pulled.
CAUTION:
When not operating the tool, always
set the reversing switch lever to the neutral position.

Depth adjustment

► Fig.8: 1. Locator
The depth can be adjusted by turning the locator. Turn
it in "B" direction for less depth and in "A" direction for
more depth. One full turn of the locator equals 2 mm
change in depth.
► Fig.9: 1. Locator
Adjust the locator so that the distance between the tip
of the locator and the screw head is approximately 3
mm as shown in the figures. Drive a trial screw into your
material or a piece of duplicate material. If the depth is
still not suitable for the screw, continue adjusting until
you obtain the proper depth setting.
