6. Opsætning

Before using your torque wrench, ensure it is properly set up:

1. Pakker ud: Carefully remove the torque wrench and all accessories from the transport case.
2. Inspicere: Check the wrench and accessories for any signs of damage. Do not use if damaged.
3. Vælg stikkontakt: Choose the appropriate socket size (17mm, 19mm, or 21mm) for your application.
4. Fastgør stikkontakt: Firmly push the selected socket onto the 1/2 inch square drive of the torque wrench until it clicks into place. If needed, use the 125mm extension bar between the wrench and the socket.

7. Betjeningsvejledning

Follow these steps to accurately apply torque using your Monzana Torque Wrench:

1. Determine Required Torque: Consult your vehicle's service manual or component specifications for the correct torque value (in Nm or M-kg).
2. Lås håndtaget op: Locate the locking screw/knob at the end of the handle. Rotate it counter-clockwise to unlock the adjustment mechanism.
3. Set Torque Value:
   • Rotate the handle to align the desired main torque value on the main scale with the zero mark on the micrometer scale.
   • Then, rotate the handle further until the desired fine adjustment value on the micrometer scale aligns with the main scale line.
   • Example: To set 100 Nm, align '100' on the main scale with the micrometer's '0'.
4. Låsehåndtag: Once the desired torque is set, rotate the locking screw/knob clockwise to secure the handle and prevent accidental changes.
5. Select Ratchet Direction: Use the small lever on the wrench head to select the desired rotation direction (clockwise for tightening, counter-clockwise for loosening). Ensure it is set for tightening.
6. Påfør moment: Place the socket onto the fastener. Apply smooth, steady pressure to the handle in the tightening direction. Do not jerk or use sudden movements.
7. Listen for Click: Continue applying pressure until you hear and feel a distinct "click" from the wrench. This indicates that the preset torque value has been reached.
8. Udløs tryk: Immediately stop applying pressure once the click is heard. Do not continue to turn the wrench past the click.
9. Repeat (if necessary): For multiple fasteners, repeat the process for each one.

8. Vedligeholdelse

Proper maintenance will extend the life and accuracy of your torque wrench:

• Rensning: After each use, wipe the wrench clean with a soft, dry cloth. Do not use solvents or harsh chemicals, as they may damage the finish or internal components.
• Opbevaring: Always return the torque wrench to its lowest torque setting (40 Nm) before storing it in its protective case. This relieves tension on the internal spring mechanism, preserving its accuracy over time. Store in a dry, cool place away from direct sunlight and extreme temperatures.
• Smøring: The internal mechanism is factory lubricated and generally does not require user lubrication. Do not attempt to lubricate the internal parts unless specifically instructed by the manufacturer.
• Kalibrering: Torque wrenches are precision measuring instruments. Their accuracy can drift over time with use. It is recommended to have your torque wrench professionally calibrated annually, or more frequently if used heavily or if accuracy is critical for your applications.

9. Fejlfinding

If you encounter issues with your torque wrench, consider the following common problems and solutions:

• Wrench does not click:
  • Ensure the torque setting is above the minimum value (40 Nm).
  • Verify that the locking screw/knob is fully tightened after setting the torque.
  • Apply smooth, steady pressure. A sudden jerk might cause you to miss the click.
  • The fastener might already be at or above the set torque.
  • If the issue persists, the wrench may require professional calibration or repair.
• Inaccurate torque readings:
  • Ensure the wrench was stored at its lowest setting.
  • Check for any visible damage to the wrench.
  • The wrench may be out of calibration. Professional calibration is recommended.
  • Ensure the fastener threads are clean and not seized.
• Socket does not attach securely:
  • Ensure the socket drive size matches the wrench (1/2 inch).
  • Check for debris or damage on the square drive or inside the socket.
  • Ensure the ball lock mechanism on the wrench head is functioning correctly.
