Hook (Fig. 3)
The hook is convenient for hooking the tool to your belt. It
can be installed on either side of the tool.
Changing the installation position of hook allows two-way
setting of 10 mm and 20 mm distance from the tool itself.
The tool with hook can be hung on the waist belt, a maxi-
mum diameter 20 mm pipe etc.
To remove the hook, just remove the clamping screw.
Place it on the tool and secure it with the clamping screw
to install.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Installing or removing the bit (Fig. 4 & 5)
Loosen the thumb screws which secure the casing. Pull
out the casing in the direction of the arrow.
Press the dust cover toward the plain bearing and pull
out the bit. If the dust cover cannot be moved as far as
the plain bearing, try it again after turning the bit slightly.
To install the bit, insert it into the socket while turning it
slightly. After installing, always make sure that the bit is
securely held in place by trying to pull it out.
Setting for desired screw length (Fig. 6)
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 indi-
cated on the label on feeder box and the respective
screw length.

Adjusting the driving depth (Fig. 7)
Depress the stopper base as far as it will go. While keep-
ing 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" direc-
tion; if the screw head is counter-sunk, turn the adjusting
knob in the "B" direction.
Installing screw strip (Fig. 8 & 9)
Insert the screw strip through the screw guide. Then
insert it through the feeder box until the first screw
reaches the position next to the driving position.
Removing screw strip (Fig. 10 & 11)
To remove the screw strip, just pull it out in the direction
of the arrow. If you depress the reverse button, you can
pull out the screw strip in the reverse direction of the
arrow.
Folding screw guide (Fig. 12)
Screw guide is foldable. Folding the screw guide allows
space used for storage to be minimal.
Extension handle (optional accessory) (Fig. 13)
Use of extension handle allows you to drive screws into
floors while standing.
OPERATION
Driving operation (Fig. 14)
Switch on the tool by pressing the switch trigger and at
the same time pushing the lock button. Hold the tool
squarely against the workpiece and apply forward pres-
sure to the tool. The screw will be automatically carried to
the driving position and driven into the workpiece.
CAUTION:
• Always hold the tool squarely against the driving sur-
face. Holding it at an angle may damage the screw

heads and cause wear on the bit. This may also lead to
25 mm
poor fastening.
• Always keep the tool firmly against the driving surface
30 mm
until the driving is over. Failure to do so may cause
insufficient fastening of screws.

already fastened.
• Do not operate the tool without screws. It will damage

Driving in corner (Fig. 15)
55 mm This tool can be used to drive at a position 15 mm away
from the wall as shown in Fig. 15.
CAUTION:
• Driving at a position closer than 15 mm to the wall or
Screw length
driving with the stopper base in contact with the wall
may damage the screw heads and cause wear on the
