1. Fastening time (second) 2. Fastening torque
NOTE: Hold the tool pointed straight at the bolt or nut.
NOTE: 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.
NOTE: 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.
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 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 some-
what 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.
