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, DO NOT abuse it.
- Maintain correct balance and footing. Ensure the floor is not slippery and wear non-slip shoes.
- Keep children and unauthorised persons away from the working area.
- WARNING! DO NOT use the wrench if damaged or thought to be faulty (Contact Service Agent).
- DO NOT drop or throw the wrench.
- DO NOT use a 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 it is packed.
- After use adjust to lowest torque setting (but not below), clean and store in a safe, dry, childproof location.
INTRODUCTION
Flip reverse Chrome Vanadium steel ratchet head with a smooth action mechanism. Scale graduated in Nm and lb.ft. Calibration tolerance under BS EN ISO 6789-1:2017. Wrenches are individually tested to standards with ±4% accuracy and each wrench is issued with an individually numbered test certificate. Aluminium knurled handle for comfort and control. Supplied in storage case.
SPECIFICATION
- Model No:…………………………………………………. STW400
- Drive:………………………………………………………….. 1/2”Sq
- Length:……………………………………………………….. 430mm
- Range:………………………………. 40-210Nm (29.5-155lb.ft)
OPERATION
- Hold torque wrench so that required scale – -foot. pounds or Newton.metres – is uppermost and visible.
- Pull the collar downwards to adjust the torque setting.
- Turn adjusting grip to select the torque setting as follows, for a required setting of 56ft.lb:
- Turn grip until the top edge of the 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 the handle further, clockwise, until 6.0 graduation on the grip is aligned with a centre line to give a setting of 50 + 6 = 56ft. lb.
- 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 overtightening nut/bolt. The wrench will reset ready for the 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.
RECALIBRATION
CALIBRATION CHECK
We recommend to ensure continued accuracy the calibration of each wrench
should be checked annually, beginning one year after first use. Calibration
should also be checked after any impact, over-torquing or other misuse.
Contact your Sealey stockist to arrange recalibration.

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 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).
