Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com INTRODUCTION Thank you for purchasing this CLARKE Torque Wrench. This torque wrench is designed to tighten nuts with precision. It should NOT be used for UNDOING nuts, as severe damage could occur. With correct use, this tool will produce an accuracy of plus or minus 4%. You can hear and feel when the desired torque setting has been reached. With careful and considerate use, the wrench will give years of reliable service.

USING YOUR TORQUE WRENCH TORQUE SETTING/ADJUSTMENT The main body is marked in Newton Metres (Nm). The barrel is marked with 10 graduations; one graduation = 0.1 Nm. To set the torque, pull the locking sleeve back and turn the body until the zero mark on the scale is in line with the next lowest graduation on the linear scale.

Smoothly tighten your fastening, applying even pressure throughout the operation. 2. ALWAYS use the correct size socket for the fastening and NEVER use sockets that are damaged. Sockets, adaptors and extensions must be robust enough for exposure to the maximum possible torque. 3. Grasp the torque wrench handle and pull on the wrench with a steady movements. 4. Check that the wrench operating range is adequate for the anticipated load before proceeding. DO NOT exceed the maximum rating of the wrench (30Nm or equivalent units). 5. NEVER use the wrench to undo bolts & nuts which may be excessively tight. Very tight nuts and bolts should be loosened with a standard wrench and the torque wrench used only for re-tightening. 6. DO NOT expose the wrench to extreme temperature or humidity or direct for extended periods. 7. Avoid using universal joints as these could result in inaccurate torque readings. 8. ALWAYS pull the wrench towards you,- DO NOT push the wrench handle. NEVER use the wrench with wet hands. CARE OF THE WRENCH DURING USE Each torque wrench has been lubricated before leaving the factory. If the wrench has not been used for some time, operate it several times allowing the lubricant to re-coat the internal working parts.

  • After use, keep adjustment at lowest torque setting.
  • DO NOT turn handle below lowest torque setting.
  • Clean by wiping the tool and the display with a soft cloth. NEVER immerse it in water or any type of solvent or cleaning fluid. Store in a clean, dry environment away from excess heat, humidity or dust.
  • The wrench has been calibrated at the factory order to ensure accurate readings and should not require any re-calibration. The original calibration certificate should be supplied. 1. NEVER exceed the permitted maximum torque value for this wrench. Overloading the wrench could cause damage. 2. Ensure that associated adaptors, extensions and sockets are rated to equal or exceed the torque being applied. 3. ALWAYS use the correct size and type of socket for the nut/bolt.
  • ALWAYS pull the wrench towards you. NEVER push it away and adjust your stance to prevent a fall should something give way unexpectedly.
