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:
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.
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. Voltage
Voltage drop will cause a reduction in the fastening
torque.
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.
