Installing hook

CAUTION:

When installing the hook, always 

secure it with the screw firmly.

 If not, the hook 

may come off from the tool and result in the personal 

injury.

CAUTION:

Use the hanging/mounting parts 

for their intended purposes only.

 Using for unin-

tended purpose may cause accident or personal 

injury.

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.12

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 M8 or smaller screw, choose 

a proper impact force and 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.
