4.2. SETTING TORQUE VALUE (g.1, g.2)
g.2
4.2.1. With the adjuster unlocked (g.1), rotate the handle to reach the main scale value i.e. 60 Nm (g.2) aligned with collar value 0.
4.2.2. To set the torque to more discrete values i.e. 52 Nm (g.2) align main scale to 50 and then rotate collar value to 2 (g.2).
4.2.3. Once the torque value is set, slide the locking ring forward to lock adjuster in position.
4.2.4. 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 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. RE-CERTIFICATION
5.1. Unless otherwise stipulated, and to ensure continued accuracy of the torque tool, a period of 12 months, or 5,000 cycles (whichever occurs
first), may be taken as default values for the interval between calibration checks. This calibration check should also be carried out if the torque
tool has been subjected to an impact, has been misused, or the readings are suspect. Jack Sealey Ltd have up-to-date calibration checking
equipment, certified to international standards, to carry out this service.
Note: It is our policy to continually improve products and as such we reserve the right to alter data, specifications and component parts without prior notice.
