Pull down the locking ring to unlock the hand grip.
4.3. Turn hand grip to select torque setting as follows:
Required setting - 56Nm Hold back the locking ring and turn hand grip until top edge is level with the 55Nm line on the shaft scale
and the 'zero' on the hand grip graduation is aligned with the centre line of the shaft scale.
Rotate the grip further, clockwise, until the '1' on the hand grip graduation is aligned with the centre line to give a setting of 55 + 1 =
56Nm.
4.4. Release the locking ring to prevent accidental alteration of the setting.
