The fastening torque is affected by a wide variety of

factors including the following. After fastening, always

check the torque with a torque wrench.

Voltage

Voltage drop will cause a reduction in the fastening torque.

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.

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.

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.

The manner of holding the tool or the material of

driving position to be fastened will affect the torque.

MAINTENANCE

CAUTION:

•

Always be sure that the tool is switched off and

unplugged before attempting to perform inspec-

tion or maintenance.

•

Never use gasoline, benzine, thinner, alcohol

or the like. Discoloration, deformation or cracks

may result.
