4. OPERATION
4.1.

4.2.
Turn knurled lock screw at the end of the handle anticlockwise to unlock the knurled adjusting grip.
4.3.
SETTING THE WRENCH IN NEWTONS
4.3.1.
Therefore to set the wrench at 100Nm:
4.3.2. Turn the grip until the top edge of the grip is level with the 98Nm line on the handle scale and the zero graduation on the grip is aligned
with the centre line of the handle scale.
4.3.3.
Rotate the handle further, clockwise, until the ‘2’ graduation on the grip is aligned with the centre line to give a setting of 98+2=100Nm.
4.3.4. Tighten the knurled lock screw at the end of the handle to prevent accidental alteration of the setting.
4.4.
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 over tightening the nut/bolt. The torque wrench will reset ready for the next application.
NOTE:
If using the Nm scale then each division on the grip graduation is equivalent to 0.5Nm (fig.1).
