FUNCTIONAL DESCRIPTION

CAUTION:
• Always be sure that the tool is switched off and
unplugged before adjusting or checking function on the
tool.
Switch action (Fig. 1)
CAUTION:
• Before plugging in 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. Tool speed
is increased by increasing pressure on the switch trigger.
Release the switch trigger to stop.
Holding the tool
Hold the tool only by the handle when performing an
operation. Do not touch the metal part.
Reversing switch action (Fig. 2)
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 counter-
clockwise rotation.
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.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Installing or removing driver bit or socket bit
(Fig. 3)
Use only bits that has inserting portion shown in the figure.
For tool with shallow bit hole
Use only these type of bit. Follow the
A = 12 mm
procedure (1).
B = 9 mm
(Note) Bit-piece is not necessary.
For tool with deep bit hole
A = 17 mm To install these types of bits, follow the
B = 14 mm procedure (1).
To install these types of bits, follow the
A = 12 mm procedure (2).
B = 9 mm (Note) Bit-piece is necessary for install-
ing the bit.
Procedure 1 (Fig. 4)
For tool without one-touch type
To install the bit, pull the sleeve in the direction of the
arrow and insert the bit into the sleeve as far as it will go.
Then release the sleeve to secure the bit.
For tool one-touch type
To install the bit, insert the bit into the sleeve as far as it
will go.
Procedure 2 (Fig. 5)
In addition to the procedure (1) above, insert the bit-piece
into the sleeve with its pointed end facing in.
To remove the bit, pull the sleeve in the direction of the
arrow and pull the bit out.
NOTE:
• If the bit is not inserted deep enough into the sleeve,
the sleeve will not return to its original position and the
bit will not be secured. In this case, try re-inserting the
bit according to the instructions above.
• When it is difficult to insert the bit, pull the sleeve and
insert it into the sleeve as far as it will go.
• After inserting the bit, make sure that it is firmly
secured. If it comes out, do not use it.
Hook
The hook is convenient for temporarily hanging the tool.
This can be removed without using a tool. This can be
installed on either side of the tool.
Installing and removing hook (Fig. 6)
Expand the upper part of the hook in both directions and
remove it. To install the hook, follow the removal proce-
dure in reverse.
OPERATION
Hold the tool firmly and place the point of the driver bit in
the screw head. Apply forward pressure to the tool to the
extent that the bit will not slip off the screw. Start the tool
slowly and then increase the speed gradually. Release
the switch trigger just as the screw bottoms out.
The proper fastening torque may differ depending upon
the kind or size of the screw/bolt, the material of the
workpiece to be fastened, etc. Refer to Fig. 7 for the rela-
tion between fastening time and wood screw size. (Mate-
rial to be fastened: Lauan)
NOTE:
• Use the proper bit for the head of the screw/bolt that
you wish to use.
• When fastening tool screws in a steel plate, the proper
fastening torque can be obtained in an extremely short
time (approx. 0.1 – 0.2 seconds). Turn the tool off as
soon as the impact sound is heard.
• Hold the tool pointed straight at the screw or the screw
and/or bit may be damaged.
• When driving wood screws, predrill pilot holes to make
driving easier and to prevent splitting of the workpiece.
The pilot holes should be slightly smaller than the wood screws in diameter.
• The size of wood screw which can be fastened with this
tool may differ depending upon the type of material to
be fastened. Always perform a test operation to deter-
mine the size of wood screw.
• When fastening bolts or nuts, always perform a test
operation to verify the adequate fastening time for your
bolt or nut. Excessive fastening torque may damage
the bolt/nut or socket bit.
MAINTENANCE
CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspection or
maintenance.
• Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may result.
