Product Usage Instructions
Safety
When using the torque wrench, ensure you comply with workshop safety rules and regulations:
- Maintain the wrench in good condition and replace damaged/worn parts with genuine parts only.
- Do not abuse the precision tool.
- Maintain correct balance and footing; ensure the floor is not slippery and wear non-slip shoes.
- Keep children and unauthorized persons away from the working area.
- Do not use the wrench if damaged or faulty; contact a Service Agent.
- Avoid dropping or throwing the wrench.
- Use the wrench only if instructed by a qualified person.
- Avoid using cleaners that might affect the high-pressure grease.
- After use, adjust to the lowest torque setting, clean, and store in a safe, dry, childproof location.
Introduction
The torque wrench features a heat-treated steel ratchet head, fully hardened and tempered, with an electrodeposition finish for corrosion resistance. It is calibrated in accordance with BS EN ISO 6789-1:2017 and comes with an individually numbered test certificate. The torque range adjustment is micrometer type with scale graduation in both Nm and lb.ft. It also has a flip reverse ratchet mechanism and is supplied in a storage case.
Operation
- Hold the torque wrench with the required scale (lb.ft or Nm) visible.
- Turn the knurled lock screw at the end of the handle anticlockwise to unlock the knurled adjusting grip.
- Turn the adjusting grip to select the torque setting.
Recalibration
To maintain accuracy, recalibrate the torque wrench annually and after any impact or misuse. Contact a NAMAS-accredited laboratory for recalibration.
FAQ
- Q: How often should I recalibrate the torque wrench?
- A: The torque wrench should be recalibrated annually and after any impact or misuse to ensure continued accuracy.

INTRODUCTION
Heat-treated steel ratchet head. Fully hardened and tempered. Electrodeposition finish for corrosion resistance. Calibration tolerance in accordance with BS EN ISO 6789-1:2017. Every wrench is tested and supplied with an individually numbered test certificate. Micrometer-type torque range adjustment with a scale graduated in both Nm and Ib.it. Flip reverse ratchet mechanism. Supplied in storage case.
SPECIFICATION
- Model no: AK624B
- Drive: 1/2″
- Length: 465mm
- Torque range : 27-204Nm (20-150lb.ft)
OPERATION
Hold the torque wrench in one hand so that the required scale (Ib.ft or Nm) is
uppermost and visible.
Turn knurled lock screw at end of the handle anticlockwise to unlock knurled
adjusting grip.
Turn to adjust grip to select torque setting as follows : Required
setting – 56lb.ft
Turn grip until top edge of grip is level with the 50lb.ft 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 the ‘6’ graduation on the grip is
aligned with the center line to give a setting of 50 + 6 = 56lb.ft.
NOTE : If using the Nm scale then each division on the grip graduation is
equivalent to 1.36Nm.
Therefore to set the wrench at 100Nm:
Turn grip until top edge of grip is level with the 94.9m 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 the ‘4’ graduation on the grip is aligned with the center line to give a setting of 94.9 + (4 × 1.36) = 94.9 + 5.44 =100.34Nm
Tighten the knurled 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 torque wrench will reset ready for the next application.
NOTE : If the torque wrench has not been used for some time, operate it a few times, at a low setting, to ensure all internal parts are matar in Mraaca
RECALIBRATION
In order to ensure continued accuracy, the torque wrench should be recalibrated annually and after any impact or other misuse. contact a NAMAS accredited laboratory.
TORQUE TOOL CALIBRATION CERTIFICATE
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).
