INTRODUCTION

Manufactured from hardened and tempered Chrome Vanadium steel with a polished satin finish. Smooth action ratchet head with flip reverse action to allow torquing in both directions. Easy to use torque adjustment, locks when required setting is selected. Calibration tolerance in accordance with 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. Supplied in storage case.

SPECIFICATION

Model No:………………………………………………………. STW704
Drive: ……………………………………………………………….. 1/2”Sq
Length:…………………………………………………………….. 610mm
Range: ……………………………………….. 60-340Nm(44-250lb.ft)

OPERATION

Hold torque wrench so that required scale – on shaft, just above hand grip – is uppermost and visible.
Pull down the locking ring to unlock the hand grip.
Turn hand grip to select torque setting as follows:
Required setting – 56Nm Hold back the locking ring and turn hand grip until top edge is level with the 55Nm line on the shaft scale
and the ‘zero’ on the hand grip graduation is aligned with the centre line of the shaft scale.
Rotate the grip further, clockwise, until the ‘1’ on the hand grip graduation is aligned with the centre line to give a setting of 55 + 1 = 56Nm.
Release the locking ring 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 wrench to avoid over-tightening the nut/bolt.
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 all internal parts are coated in grease

RECALIBRATION

To ensure continued accuracy the wrench should be recalibrated annually and after any impact or other misuse. Contact an NAMAS accredited laboratory.

Notes

1 Testing is in compliance with International Standard procedures, with test equipment calibrated by a

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. 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)
