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 automatically
and the battery indicator shows following state. In this

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 direction of
rotation before the tool stops may damage the tool.
Fig.6
This tool has a reversing switch to change the direction
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
position, 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.7
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.8
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.
Hook
CAUTION:
Always remove the battery when hanging the tool
•
with the hook.
Never hook the tool at high location or on
•
potentially unstable surface.
Fig.9
The hook is convenient for temporarily hanging the tool.
ASSEMBLY
CAUTION:
Always be sure that the tool is switched off and the
•
battery cartridge is removed before carrying out
any work on the tool.
Installing or removing the bit
Fig.10
To remove the bit, pull the locator. Then grasp the bit
with a pair of pliers and pull the bit out of the magnetic
bit holder. Sometimes, it helps to wiggle the bit with the
pliers as you pull.
