Switch action (Fig. 5)
CAUTION:
• Before inserting the battery cartridge into the tool,
always check to see that the switch trigger actuates
properly and returns to the “OFF” position when
released.
To start the tool, simply pull the switch trigger. Release
the switch trigger to stop.
Reversing switch action (Fig. 6)
This tool has a reversing switch to change the direction of
rotation. Depress the reversing switch lever from the A
side for clockwise rotation or from the B side for
counterclockwise rotation.
When the reversing switch lever is in the neutral position,
the switch trigger cannot be pulled.
CAUTION:
• Always check the direction of rotation before operation.
• Use the reversing switch only after the tool comes to a
complete stop. Changing the direction of rotation
before the tool stops may damage the tool.
• When not operating the tool, always set the reversing
switch lever to the neutral position.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and the
battery cartridge is removed before carrying out any
work on the tool.
Installing or removing the bit
Loosen the thumb screws which secure the casing. Pull
out the casing in the direction of the arrow. (Fig. 7)
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. (Fig. 8)
Installing screw strip
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. (Fig. 9 & 10)
Removing screw strip
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.
(Fig. 11 & 12)
Folding screw guide (Fig. 13)
Screw guide is foldable. Folding the screw guide allows
space used for storage to be minimal.
Carry hook
The carry hook is convenient for temporarily hooking the
tool. It can be installed on either side of the tool. When
removing the carry hook, widen it by pressing its right
ends ON BOTH SIDES in the directions of arrow (1) and
raise it in the direction of the arrow (2). (Fig. 14)
OPERATION
Driving operation (Fig. 15)
Switch on the tool by pulling the switch trigger. Hold the
tool squarely and firmly up against the driving surface. A
screw will be automatically carried to the driving position
and fastened.
CAUTION:
• Always check the bit carefully for wear before driving
operations. Replace a worn bit or poor fastening may
result.
• Always hold the tool squarely against the driving
surface. Holding it at an angle may damage the screw
heads and cause wear on the bit. This may also lead to
poor fastening.
• Always keep the tool firmly against the driving surface
until the driving is over. Failure to do so may cause
insufficient fastening of screws.
• Be careful not to drive a screw onto another screw
already fastened.
• Do not operate the tool without screws. It will damage
the driving surface.
• Do not apply oil or grease on the sliding surface of the
feeder box.
Driving in corner (Fig. 16)
This tool can be used to drive at a position 15 mm away
from the wall as shown in the figure.
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 the
battery cartridge is removed before attempting to
perform inspection or maintenance.
• Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may result.
Replacing carbon brushes (Fig. 17)
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.
Loosen the thumb screws which secure the casing. Pull
out the casing in the direction of the arrow. (Fig. 18)
Use a screwdriver to remove two screws then remove the
front cover. (Fig. 19)
Raise the arm part of the spring and then place it in the
recessed part of the housing with a slotted bit screwdriver
of slender shaft or the like. (Fig. 20)
Use pliers to remove the carbon brush caps of the carbon
brushes. Take out the worn carbon brushes, insert the
new ones and replace the carbon brush caps in reverse.
(Fig. 21)
Make sure that the carbon brush caps have fit into the
holes in brush holders securely. (Fig. 22)
Reinstall the front cover and tighten two screws securely.
