ADJUSTING THE SCREW LENGTH AND
SCREW-IN DEPTH
1. Set the screw length (Fig. 1)
Set the screw length on this unit by sliding the guide
block.
(1) Slide the guide block while holding down the lever
and align the arrow on the guide block with the
number on the stopper to match the screw length.
(2) Find the screw length and screw guide position by
checking the table below.
STOPPER NUMBER
28
32
41
2. Adjust the screw-in depth (Fig. 2)
Adjust the screw-in depth on this unit by turning the
depth adjuster knob.
(1) Press the slider all the way in to the slider case. Then
rotate the depth adjuster knob so that the bit tip
protrudes about 5 mm.
(2) Try driving a screw and make fine adjustments as
needed. To make the fine adjustment, rotate towards
A (counterclockwise) if the screw head is too high
after screw-in. If the screw head is too low after
screw-in, then rotate towards B (clockwise).
INSTALLING AND REMOVING THE SCREW
STRIP
1. Install (Fig. 3)
(1) Insert the tip of the linked screw strip into the belt
guide groove (A section).
(2) Insert the tip of the tape into the slider groove (B
section) and press inwards in the arrow direction.
(3) Set so the screw on the strip is just prior (1 screw
width) to the screw-in position (Fig. 4, Fig. 5).
CAUTION
Set the screw strip securely inside. If not set securely,
the bit might scratch the board surface (low feed
pressure) or the screw might be wasted (too much
feed pressure).
2. Removal (Fig. 6)
(1) If you run out of screws on the tape or want to
remove a screw strip during a job, pull in the direction
of the arrow as shown in the figure to remove.
(2) You can return the screw strip in the opposite direction
by pressing the reverse button.
INSTALLING AND REMOVING THE BIT
CAUTION
To prevent the chance of an accident, always turn off
the power switch and pull out the plug from the
socket.
NOTE
When replacing the bit be sure to install it securely so
it will not come loose or fall out later.
1. Removing the screw strip attachment
Grip the unit securely with one hand. With your other
hand, rotate the screw strip attachment in the direction
SCREW LENGTH
25 – 28 mm
32 – 35 mm
38 – 41 mm
of the arrow in Fig. 17. Next pull in the direction of
the arrow in Fig. 18 and remove.
NOTE
This will be hard to remove if the lath or plaster
powder attaches near the attachment slot. Clean this
section carefully to prevent the lath or plaster powder
from adhering here.
2. Attaching and removing the bit (Fig. 7)
No bits other than plus driver (Phillips) bits (No. 2,
136 mm long) can be used for screw strip tightening
jobs.
Attach the bits securely using the following procedure.
Move the guide sleeve to the top edge, feed the bit
into hexagonal hole on the anvil and then release the
guide sleeve.
To remove, perform the above procedure in reverse
order.
NOTE
The bit was not installed correctly (securely) if the
guide sleeve will not return to its original position.
Keep inserting the bit inside the hexagonal socket
head hole until it makes contact.
3. Installing the screw strip attachment
Install using the steps in "1. Removing the screw
strip attachment" in reverse order.
HOW TO USE
CAUTION
Always use safety goggles during the work.
1. How to operate
Press the unit straight up against the work and pull
the switch trigger to automatically feed and tighten
the screws (Fig. 8).
NOTE
Place this unit straight up against the work during
screw-tightening. Using the unit while at an angle to
the work might damage the screw head or cause bit
wear. Also the proper tightening torque will not be
transmitted to the screw and might cause the screw
to seat improperly.
Press firmly on the unit until the screw tightening is
complete. Loosening the pushing pressure on the
unit might cause the screw to seat improperly.
When driving the screw, avoid hitting the unit as
pushing in.
This could prevent the screw from being sent
normally.
Attempting to tighten one screw on top of another
will cause the screw to fall or stop the screw feed so
use caution.
Driving blanks
During continuous screw tightening, you might not
notice you have run out of screws and continue to
operate the unit. Driving without any screws will
cause the bit to damage the lath or plaster board, so
do the screw tightening while checking the number
of screws remaining.
If the slider does not move smoothly, try cleaning the
sliding surfaces with an air gun, etc.
2. Using in corners (Fig. 9)
Unit can drive screws at positions as close as 15 mm
from the wall.
NOTE
Do not attempt to drive screws when closer to the
wall than 15 mm.
