TORQUE SETTING ADJUSTMENT
1. Loosen the lock nut on the bottom of the
torque wrench by turning it anti-clockwise.
2. Set the required torque by turning the
knurled handle.
•
Read the scale from the centreline adding
on the number on the knurled handle.
3. Finally, tighten lock nut to secure the
setting.
4. To loosely install or remove nuts without the
torque facility, move the ratchet selection
switch to the required side.
Note: The wrench cannot be used to tension
left-handed threads.
TIGHTENING USING THE TORQUE WRENCH
1. Place the square drive on to the socket or extension bar, perpendicular to the nut/bolt
to be tightened.
2. Gripping the knurled handle with one hand, whilst steadying the square drive end with
the other, gently but firmly, pull the handle (i.e. in a clockwise direction) until a click is
heard and a slight 'break' in the handle is felt. DO NOT turn any further.
IMPORTANT
•
Do not jerk the torque wrench in any way to tighten a nut. Apply an even pressure
throughout the operation.
•
Release the wrench immediately the click is heard/felt.
•
It should be noted that the 'click' from the mechanism becomes weaker with the lower
torque settings.
•
Do not turn handle below lowest torque setting.
