NOTE: If the driver bit/socket bit is not inserted deep
enough into the sleeve, the sleeve will not return to its
original position and the driver bit/socket bit will not
be secured. In this case, try re-inserting the driver bit/
socket bit according to the instructions above.
NOTE: After inserting the driver bit/socket bit, make
sure that it is firmly secured. If it comes out, do not
use it.
Installing hook
Optional accessory
The hook is useful to hang the tool. Install the hook to
the holes on the tool body.

OPERATION
CAUTION:
Pressing excessively on the tool
will not speed up the drilling. In fact, this excessive
pressure will only serve to damage the tip of your drill
bit, decrease the tool performance and shorten the
service life of the tool.
CAUTION:
Always secure workpieces in a
vise or similar hold-down device.
Hold the tool firmly and place the point of the driver bit/
socket 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.
NOTICE:
Use the proper bit for the head of the
screw/bolt that you wish to use.
NOTICE:
Hold the tool pointed straight at the
screw.
NOTICE:
If you tighten the screw for a long
time, 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.
NOTICE:
If the tool is operated continuously
until the battery cartridge has discharged, allow
the tool to rest for 15 minutes before proceeding
with a fresh battery.
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 use of the universal joint or the socket adapter
somewhat reduces the fastening force of the tool.
Compensate by fastening for a longer period of
time.
5.
Type of materials to be fastened, the manner of
holding the tool and the tool speed will affect the
torque.
6.
Operating the tool at low speed will cause a reduc-
tion in the fastening torque.
