Tool with the detent pin on the
square drive
Align the hole in the side of the impact socket with the
detent pin on the square drive and push the impact
socket onto the square drive until it locks into place. Tap
it lightly if required.
To remove the impact socket, simply pull it off. If it is
hard to remove, depress the detent pin while pulling the
impact socket.

Installing hook
Optional accessory
The hook is useful to hang the tool. Install the hook to
the holes on the tool body.

OPERATION
CAUTION:
Always insert the battery cartridge
all the way until it locks in place. If you can see the
red indicator on the upper side of the button, it is not
locked completely. Insert it fully until the red indicator
cannot be seen. If not, it may accidentally fall out of
the tool, causing injury to you or someone around
you.
CAUTION:
Hold the tool firmly and place the
impact socket over the bolt or nut. Turn the tool on
and fasten for the proper fastening time.
CAUTION:
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 cartridge.
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.
The proper fastening torque may differ depending upon
the kind or size of the bolt, the material of the workpiece
to be fastened, etc.

NOTICE:
When fastening small bolts, carefully
adjust pressure on the switch trigger so that the bolt
is not damaged.
NOTICE:
Hold the tool pointed straight at the bolt
or nut.
NOTICE:
Excessive fastening torque may damage
the bolt/nut or impact socket. Before starting your
job, always perform a test operation to determine the
proper fastening time for your bolt or nut.
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.
Impact socket
•
Failure to use the correct size impact socket
will cause a reduction in the fastening torque.
•
A worn impact socket (wear on the hex end
or square end) 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 extension
bar somewhat reduces the fastening force of the
impact wrench. Compensate by fastening for a
longer period of time.
5.
The manner of holding the tool or the material
of driving position to be fastened will affect the
torque.
6.
Operating the tool at low speed will cause a reduc-
tion in the fastening torque.
