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 plane bearing and pull
out the bit. If the dust cover cannot be moved as far as
the plane 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 3 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 plate) appear to
rest on the very top edge of the casing. See the table
below for the relation between the number indicated on
the plate and the respective screw length ranges.

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
1. Squeeze the lock lever with fingers and open the
magazine cap. (Fig. 8)
2. Roll up the screw strip in a form of coil counterclock-
wise and place it inside the magazine. (Fig. 9)
3. Run the end of the screw strip on the slotted pas-
sage starting from above the magazine. (Fig. 10)
4. Close the magazine cap while squeezing the lock
lever with fingers. (Fig. 11)
5. Insert the top end of the screw strip into the portion
A of the feeder box and feed it in the direction of the
arrow. (Fig. 12)
6. Set the screw strip so that the first screw of the strip
seats with a space for one screw left before the
screw-driving position. (Fig. 13)
Removing screw strip (Fig. 14 & 15)
When removing the screw strip at or before using up the
screws, 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.

OPERATION

Driving operation (Fig. 17)
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.
NOTE:
• Do not fire the tool without screws. This will damage
the workpiece.
• Do not apply oil or grease on the sliding surface of the
feeder box.
Driving in corner
This tool can be used to drive at a position 15 mm away
from the wall as shown in Fig. 18.
CAUTION:
• Driving at a position closer than 15 mm to the wall or
driving with the stopper base in contact with the wall
may damage the screw heads and cause wear on the
bit. This may also lead to poor fastening of screws and
malfunction of the tool.

MAINTENANCE

CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspection or
maintenance.
Replacing carbon brushes
Remove and check the carbon brushes regularly.
Replace when they wear down to the limit mark. Keep
the carbon brushes clean and free to slip in the holders.
Both carbon brushes should be replaced at the same
time. Use only identical carbon brushes. (Fig. 19)
Use a screwdriver to remove the brush holder caps. Take
out the worn carbon brushes, insert the new ones and
secure the brush holder caps. (Fig. 20)
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be per-
formed by Makita Authorized or Factory Service Centres,
always using Makita replacement parts.
