3. Extension cord
When the work area is removed from the power source,
use an extension cord of suffi cient thickness and rated
capacity. The extension cord should be kept as short as
practicable.
4. Preparing and checking the work environment
Make sure that the work site meets all the conditions laid
forth in the precautions.
5. Preparing the screws
Select screws appropriate to the application.
6. Bit checking and replacement
A No. 2 Plus bit is installed on this machine as a
standard accessory. Always inspect the bit to make sure
it is not damaged. Using worn bits can cause screw-in
malfunctions. Inspect the bit before work and quickly
replace it with a new one when it starts to wear out. When
the bit must be replaced due to bit damage or any other
reason, replace it according to the instructions in Bit
installation and removal.
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.

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 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. 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 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 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 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 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.
