Hold the tool firmly and place the socket over the bolt or
nut. Turn the tool on and fasten for the proper fastening
time.
NOTE:
When fastening screw M8 (5/16") or smaller, care-
fully adjust pressure on the switch trigger so that
the screw is not damaged.
Hold the tool pointed straight at the bolt or nut.
Excessive fastening torque may damage the bolt/
nut or socket. Before starting your job, always per-
form a test operation to determine the proper fas-
tening time for your bolt or nut. Especially for the
bolt smaller than M8 (5/16"), perform the above test
operation to prevent the trouble on socket or bolt,
etc.
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 fac-
tors 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.
Socket
Failure to use the correct size socket will cause
a reduction in the fastening torque.
A worn 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 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 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.
