Procedure 1
► Fig.7: 1. Driver bit 2. Sleeve
To install the driver bit, pull the sleeve in the direction of
the arrow and insert the driver bit into the sleeve as far
as it will go.
Then release the sleeve to secure the driver bit.
Procedure 2
In addition to Procedure 1, insert the bit-piece into the
sleeve with its pointed end facing in.
► Fig.8: 1. Driver bit 2. Bit-piece 3. Sleeve
To remove the driver bit, pull the sleeve in the direction
of the arrow and pull the driver bit out.
NOTE: If the driver bit is not inserted deep enough
into the sleeve, the sleeve will not return to its original
position and the driver bit will not be secured. In this
case, try re-inserting the bit according to the instruc-
tions above.
NOTE: After inserting the driver bit, make sure that it
is firmly secured. If it comes out, do not use it.
OPERATION
CAUTION:
When bending the tool to use in
the pistol shape or straightening to use in the
straight shape, do not hold the bendable part of
the tool. Failure to do so may cause your hand and
fingers to be pinched and injured by this part.
► Fig.9: 1. Straight shape 2. Pistol shape
The tool can be used in two ways; a straight shape and
a pistol shape which are selectable according to the
conditions of workplace and screwdriving.
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 fas-
tening torque and fastening time is shown in the figures.

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.
NOTICE:
If you use a spare battery to continue
the operation, rest the tool at least 15 min.
NOTE: Use the proper bit for the head of the screw/
bolt that you wish to use.
NOTE: When fastening M5 or smaller screw, carefully
adjust rotation angle on the switch so that the screw
is not damaged.
NOTE: Hold the tool pointed straight at the screw.
NOTE: If the impact force is too strong or you tighten
the screw for a time longer than shown in the figures,
the screw or the point of the driver bit may be over-
stressed, 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. When the battery cartridge is discharged almost
completely, voltage will drop and the fastening
torque will be reduced.
2. Driver bit or socket bit
Failure to use the correct size driver bit or socket
bit will cause a reduction in the fastening torque.

3. 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.
4. The manner of holding the tool or the material
of driving position to be fastened will affect the
torque.
5. Operating the tool at low speed will cause a reduc-
tion in the fastening torque.
