• Length: ………………………………………………………. 245mm
• Range: ………………………………….. 5-25Nm (3.7-18.5lb.ft)

OPERATION

PREPARING TO SET TORQUE (fig.1)
Release torque adjuster by sliding the collar backwards. Set torque (see 4.2) and then lock in place by sliding the collar forwards.

SETTING TORQUE VALUE (fig.1, fig.2)

1. With the adjuster unlocked (fig.1), rotate the handle to reach the main scale value i.e. 60 Nm (fig.2) aligned with collar value 0. 4.2.2. To set the torque to more discrete values i.e. 52 Nm (fig.2) align main scale to 50 and then rotate collar value to 2 (fig.2).
2. Once the torque value is set, slide the locking ring forward to lock adjuster in position.
3. 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.

RE-CERTIFICATION

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.

Notes:

1. Testing is in compliance with International Standard procedures, with test equipment calibrated by a laboratory traceable to International Standards.
2. Measurement error shall be less than ¼ of the maximum permissible relative deviation of the torque tool.
3. The observed values fall within the maximum permissible deviation (tolerance). For tools with a flexible head, the result is valid only if the measuring axis is perpendicular to the axis of the tool.
4. This Sealey Declaration of Conformance is issued at the time of manufacture and its validity is open ended until the torque tool is used for the first time. Unless otherwise stipulated, 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 period starts after first use of the torque tool. (BS EN ISO 6789-1:2017, clause 5.3 refers).
