OPERATION
3.1. Hold torque wrench in one hand so that required scale (lb.ft or Nm) is uppermost and visible.
3.2. Turn knurled lock screw at end of handle anticlockwise to unlock knurled adjusting grip.
3.3. Turn adjusting grip to select torque setting as follows:
• Required setting - 56lb.ft
• Turn grip until top edge of grip is level with the 50lb.ft line on the handle scale and the zero graduation on
the grip is aligned with the centre line of the handle scale.
• Rotate the handle further, clockwise, until the '6' graduation on the grip is aligned with the centre line to
give a setting of 50 + 6 = 56lb.ft.
Note: If using the Nm scale then each division on the grip graduation is equivalent to 1.36Nm.
Therefore to set wrench at 100Nm:
• Turn grip until top edge of grip is level with the 94.9Nm line on the handle scale and the zero graduation on
the grip is aligned with the centre line of the handle scale.
• Rotate the handle further, clockwise, until the '4' graduation on the grip is aligned with the centre line to
give a setting of 94.9 + (4 x 1.36) = 94.9 + 5.44 =100.34Nm
3.4. Tighten the knurled lock screw at the end of the handle to prevent accidental alteration of the setting.
3.5. When tightening the nut/bolt you will feel and hear the wrench mechanism click when the set torque is reached.
Immediately stop applying force to the wrench to avoid overtightening the nut/bolt. The torque wrench will reset
ready for the next application.
Note: If the torque wrench has not been used for some time, operate it a few times, at a low setting, to
ensure all internal parts are coated in grease.
4.
RECALIBRATION
4.1. In order to ensure continued accuracy, the torque wrench should be recalibrated annually and after any
impact or other misuse. Contact a NAMAS accredited laboratory.
