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. Do not use any other driver bit or socket bit.
For European and North & South American countries,
Australia and New Zealand
A=12 mm
Use only these type of bit. Follow the
B=9 mm
procedure (1).
(Note) Bit-piece is not necessary.
For other countries
A=17 mm
To install these types of bits, follow the
B=14 mm
procedure (1).
(Note) Makita bits are these types.
A=12 mm
To install these types of bits, follow the
B=9 mm
procedure (2).
(Note) Bit-piece is necessary for installing
the bit.
1. 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. (Fig. 4)
2. To install the bit, pull the sleeve in the direction of the
arrow and insert the bit-piece and bit into the sleeve
as far as it will go. The bit-piece should be inserted
into the sleeve with its pointed end facing in. Then
release the sleeve to secure the bit. (Fig. 5)
To remove the bit, pull the sleeve in the direction of the
arrow and pull the bit out firmly.
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.
OPERATION (Fig. 6)
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. The relation between
fastening torque and fastening time is shown in the
figures.
Hold the tool only by the handle when performing an
operation.
NOTE:
• 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
determine the size of wood screw. (Fig. 7 & 8)
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 and turn the
tool on to start operation.
NOTE:
• Use the proper bit for the head of the screw/bolt that
you wish to use.
• When fastening screw M8 or smaller, carefully adjust
pressure on the switch trigger so that the screw is not
damaged.
• Hold the tool pointed straight at the screw.
• If you tighten the screw for a time longer than shown in
the figures, the screw or the point of the driver bit may
be overstressed, stripped, damaged, etc. Before
starting your job, always perform a test operation to
determine the proper fastening time for your screw.
The fastening torque is affected by a wide variety of
factors including the following. After fastening, always
check the torque with a torque wrench.
1. Driver bit or socket bit
Failure to use the correct size driver bit or socket bit
will cause a reduction in the fastening torque.
2. Bolt
• Even though the torque coefficient and the class of
bolt are the same, the proper fastening torque will
differ according to the diameter of bolt.
• Even though the diameters of bolts are the same,
the proper fastening torque will differ according to
the torque coefficient, the class of bolt and the bolt
length.
3. The manner of holding the tool or the material of
driving position to be fastened will affect the torque.
4. Operating the tool at low speed will cause a reduction
in the fastening torque.
MAINTENANCE
CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspection or
maintenance.
To maintain product SAFETY and RELIABILITY, repairs,
carbon brush inspection and replacement, any other
maintenance or adjustment should be performed by
