ADJUSTING THE SCREW LENGTH AND
SCREW-IN DEPTH
1. Set the screw length (Fig. 8)
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

41
2. Adjust the screw-in depth (Fig. 9)
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 fi ne adjustments as
needed. To make the fi ne 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. 10)
(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. 11, Fig. 12).
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. 13)
(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 fi gure 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 remove the battery from the body.
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
of the arrow in Fig. 14. Next pull in the direction of the
arrow in Fig. 15 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. 16)
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.
Adjust the rotation direction to the clockwise
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. 17).
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 fi rmly 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. 18)
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.
Do not drive screws while the slider case is in contact
with the wall. Damaging the screw head causes bit
wear. The proper tightening torque is not transmitted to
the screw if the screw head or bit is worn. This might
also cause the screw not to seat properly and might
cause this unit to break.
3. Removing the screws
The tightened screws can be removed by rotating them
for the reverse rotation
Properly install the bit against the groove on the screw
head, and pull the switch trigger while depressing the
bit against the groove vertically.
