Procedure 2

In addition to 

Procedure 1

, insert the bit-piece into the 

sleeve with its pointed end facing in.

 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:

 When it is difficult to insert the driver bit, pull 

the sleeve and insert it into the sleeve as far as it will 

go.

NOTE:

 After inserting the driver bit, make sure that it 

is firmly secured. If it comes out, do not use it.

Installing hook

 Screw

The hook is convenient for temporarily hanging the tool. 

This can be installed on either side of the tool. To install 

the hook, insert it into a groove in the tool housing on 

either side and then secure it with a screw. To remove, 

loosen the screw and then take it out.

OPERATION

► 

Fig.15

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.

 Fastening torque

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 M8 or smaller screw, carefully 

adjust pressure on the switch trigger 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 fasten-

ing torque will differ according to the diame-

ter 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.
