inconsistent fastening torque and/or damage to the bolt or
nut.
Installing or removing socket (Fig. 5)
To install the socket, push it onto the anvil of the tool until
it locks into place.
To remove the socket, simply pull it off.
OPERATION (Fig. 6)
The proper fastening torque may differ depending upon
the kind or size of the bolt, the material of the workpiece to
be fastened, etc. The relation between fastening torque
and fastening time is shown in the figures. (Fig. 7 & 8)
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 or smaller, carefully adjust
pressure on the switch trigger so that the screw is not
damaged.
• Hold the tool pointed straight at the bolt or nut without
applying excessive pressure on the tool.
• Excessive fastening torque may damage the bolt/nut or
socket. Before starting your job, always perform a test
operation to determine the proper fastening time for
your bolt or nut. Especially for the bolt smaller than M8,
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 more
than 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. 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 reduction
in the fastening torque.
