4. OPERATION 4.1. Hold torque wrench in left hand (if right handed) so that required scale - foot.pounds or Newton.metres - is uppermost and visible. 4.2. Turn knurled lock screw at end of handle anticlockwise to unlock knurled adjusting grip. 4.3. Turn adjusting grip to select torque setting as follows, for a required setting of 56ft.lb: Turn grip until top edge of grip is level with the 50ft.lb line on the handle scale and the zero graduation on the grip is aligned with the centre line of the handle scale. Rotate handle further, clockwise, until 6th graduation on grip is aligned with centre line to give a setting of 50 + 6 = 56ft.lb. NOTE: If using the N.m scale then each division on the grip graduation is equivalent to 1.36N.m. Therefore to set wrench at 76N.m: Turn grip until top edge of grip is level with the 67.8N.m 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 6th graduation on the grip is aligned with the centre line to give a setting of 67.8 + (6 x 1.36) = 67.8 + 8.2 = 76N.m. 4.4. Tighten lock screw at end of handle to prevent accidental alteration of the setting. 4.5. 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 wrench to avoid overtightening nut/bolt. Wrench will reset ready for next application. NOTE: If the 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.
5. RECALIBRATION 5.1. CALIBRATION CHECK We recommend to ensure continued accuracy the calibration of each wrench should be checked annually, beginning one year after firstuse.Calibrationshouldalsobecheckedafteranyimpact,over-torquingorothermisuse.ContactyourSealeystockisttoarrange recalibration.
