Operating Instructions

The M-Wave TW-3/10 Torque Wrench is designed for precise torque application within its specified range. Always refer to the manufacturer's recommended torque settings for the component you are working on.

1. Determine Required Torque: Identify the correct torque specification (in Newton-meters, Nm) for the fastener you are tightening. This information is usually found in the component's manual or on the component itself.
2. Set the Torque Value: The M-Wave TW-3/10 has a fixed torque range of 3-10 Nm. The wrench is designed to click or give a tactile indication when the set torque is reached. The scale on the wrench indicates the approximate torque setting. Ensure you are within the 3-10 Nm range.
3. Position the Wrench: Place the bit firmly into the head of the fastener. Ensure the wrench is perpendicular to the fastener to avoid stripping.
4. Apply Force: Apply slow, steady, and increasing force to the handle of the torque wrench. Do not use sudden jerks or excessive force.
5. Listen for the Click: Continue applying force until you feel and/or hear a distinct "click" or break in the wrench's movement. This indicates that the preset torque value has been reached.
6. Stop Immediately: Once the click is felt/heard, stop applying force immediately. Do not continue to tighten the fastener beyond this point, as over-tightening can damage components or the wrench itself.
7. Remove the Wrench: Carefully remove the torque wrench from the fastener.

Important Safety Notes:

• Always use the correct bit size for the fastener.
• Never use the torque wrench as a breaker bar or for loosening fasteners.
• Do not exceed the maximum torque rating of 10 Nm.
• Keep the wrench clean and free from dirt or debris.

Maintenance

Proper maintenance will extend the life and accuracy of your M-Wave TW-3/10 Torque Wrench.

• Cleaning: After each use, wipe down the wrench with a clean, dry cloth to remove any dirt, grease, or moisture. Do not use harsh chemicals or abrasive cleaners.
• Storage: Store the torque wrench in a clean, dry place, away from extreme temperatures and humidity. It is recommended to store it in its original packaging or a protective case to prevent damage.
