• Overloaded:
The tool is operated in a manner that causes it to
draw an abnormally high current.
In this situation, release the trigger switch on the tool
and stop the application that caused the tool to
become overloaded. Then pull the trigger switch
again to restart.
If the tool does not start, the battery is overheated. In
this situation, let the battery cool before pulling the
trigger switch again.
• Low battery voltage:
The remaining battery capacity is too low and the tool
will not operate. In this situation, remove and
recharge the battery.
Indicating the remaining battery capacity
Only for battery cartridges with the indicator (Fig. 3)
Press the check button on the battery cartridge to indicate
the remaining battery capacity. The indicator lamps light
up for a few seconds.

Lighted Off
NOTE:
• Depending on the conditions of use and the ambient
temperature, the indication may differ slightly from the
actual capacity.
Setting for desired screw length (Fig. 4)
There are 7 positive-lock screw length settings. To obtain
the desired setting, pull out the stopper base while
depressing the lever until you see the number of the
desired screw length (indicated on the label on feeder
box) appear to rest in the fenestella of stopper base. See
the table below for the relation between the number
indicated on the label on feeder box and the respective
screw length.

Adjusting the driving depth (Fig. 5)
Depress the stopper base as far as it will go. While
keeping it in this position, turn the adjusting knob until the
bit tip projects approx. 5 mm from the stopper base. Drive
a trial screw. If the screw head projects above the surface
of the workpiece, turn the adjusting knob in the "A"
direction; if the screw head is counter-sunk, turn the
adjusting knob in the "B" direction.
Switch action (Fig. 6)
CAUTION:
• Before inserting the battery cartridge into the tool,
always check to see that the switch trigger actuates
properly and returns to the "OFF" position when
released.
To start the tool, simply pull the switch trigger. Release
the switch trigger to stop.
Reversing switch action (Fig. 7)
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
counterclockwise rotation.
When the reversing switch lever is in the neutral position,
the switch trigger cannot be pulled.
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.
• When not operating the tool, always set the reversing
switch lever to the neutral position.
