SAFETY
Ensure all workshop safety rules, regulations, and conditions are complied
with when using the torque wrench.
Maintain the wrench in good condition and replace any damaged or worn parts.
Use genuine parts only. Unauthorised parts may be dangerous and will
invalidate the warranty.
The wrench is a precision tool, handle with care.
Maintain correct balance and footing. Ensure the floor is not slippery and
wear non-slip shoes.
If it is suspect that the wrench is damaged or faulty, have it checked by
Sealey or one of our Service Agents.
DO NOT use wrench unless you have been instructed in its use by a qualified
person.
DO NOT use any cleaner which might affect the high pressure grease with which
the wrench is packed.
INTRODUCTION
Chrome Vanadium steel ratchet head with smooth action mechanism. Calibration tolerance in accordance with BS EN ISO 6789:2017. Scales graduated in both Nm and lb.in/lb.ft. Wrenches are individually tested to standards with ±4% accuracy and each wrench is issued with an individually numbered calibration certificate. Supplied in storage case.

OPERATION
-
After use adjust to lowest torque setting (but not below), clean and store in a safe, dry, childproof location.
-
Hold the torque wrench in your left hand (if right handed) so that the required scale on the shaft, just above the hand grip – is uppermost and visible.
-
Turn the lock screw, in the end of the grip, counter-clockwise to unlock grip (STW201.V2 has a locking plug in the end of the grip – pull ring to unlock).
Turn grip to select torque setting as follows:
If the required setting – 56Nm. Turn grip until top edge is level with the 50Nm line on the shaft scale and thezero’ on the grip graduation is aligned with the centre line of the shaft scale. Rotate the grip further, clockwise, until the6′ on the grip graduation is aligned with the centre line to give a setting of 50 + 6 = 56Nm.
NOTE: If using the alternative scale (lb.in, lb.ft or kg.m depending on wrench) then each division of the grip graduation is equivalent to the scale increment divided by the number of divisions. For example (STW1011):
The alternative scale is in lb.ft. Scale increments are 5.16lb.ft. There are 7 grip divisions. Then each division is 5.16/7 = 0.74lb.ft -
Tighten the lock screw at the end of the handle to prevent accidental alteration of the setting.
-
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 the wrench to avoid over-tightening the nut/bolt. The wrench will reset ready for the next application.
NOTE: If wrench is not used for some while, operate it a few times, at a low setting, to ensure that all internal parts are coated in grease.
RECALIBRATION
- The default calibration period of 12 months (or 5000cycles which ever occurs first) starts after the first use of the torque tool (BS EN ISO 6789-1 refers).
- Calibration should be checked periodically, depending on use and after any impact or other misuse. Also the interval between tests shall be chosen on the basis such as: maximum permissible deviation, frequency of use, typical load during operation as well as ambient conditions during operation and storage.

Notes:
- Testing is in compliance with International Standard procedures, with test equipment calibrated by a laboratory traceable to International Standards.
- Measurement error shall be less than ¼ of the maximum permissible relative deviation of the torque tool.
- 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.
- This Sealey Declaration of Conformance is issued at the time of manufacture. Its’ validity is open ended until the torque tool is used for the first time. The default re-calibration period of 12 months (or 5,000 cycles, whichever occurs first) starts after first use of the torque tool (BS EN ISO 6789-1:2017, clause 5.3 refers).
