Fastening time
NOTE:
•
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 perform a test operation to determine the
proper fastening time for your bolt or nut.
•
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.
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 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.
