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:
•
•
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
2. Socket
3. Bolt

Fastening time
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.
Voltage drop will cause a reduction in the fastening
torque.
• 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.
• 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.
