2. Safety Information
Always read and understand all instructions before using the torque wrench. Failure to follow these instructions may result in damage to the tool, components, or personal injury.
- Wear appropriate safety gear, such as safety glasses, when using tools.
- Ensure the correct bit size is used for the fastener to prevent stripping.
- Do not exceed the maximum torque rating of the wrench (20 N·m).
- Do not use the torque wrench as a breaker bar or for loosening fasteners.
- Keep the tool clean and dry.

4. Setup and Torque Adjustment
4.1. Installing Bits/Adapters
- Select the appropriate bit for your fastener.
- Press the quick-release button on the top of the torque wrench head.
- Insert the chosen bit or adapter into the drive head until it clicks securely into place.

4.2. Setting the Torque Value
- Locate the lock ring at the base of the handle.
- Pull down the lock ring to unlock the adjustment mechanism.
- Rotate the handle:
- Clockwise to increase the torque value.
- Counter-clockwise to reduce the torque value.
- Align the desired torque value on the electroplated laser scale. The actual N·m value is the sum of the upper value (main scale) and the lower value (fine adjustment scale).
- Once the desired torque is set, push the lock ring back up to secure the setting.
Figure 5: Reading the torque scale. Example: Upper value 2 + Lower value 0.2 = 2.2 N·m.
5. Operating Instructions
5.1. Applying Torque
- Ensure the torque wrench is set to the correct torque value and the lock ring is engaged.
- Place the bit firmly into the fastener head.
- Apply steady, smooth pressure to the handle in the tightening direction (clockwise for most fasteners).
- Continue applying pressure until you hear and feel a distinct "click" sound. This indicates that the preset torque has been reached.
- Immediately stop applying force once the "click" is heard. Do not twist hard after the beep is present.

5.2. Two-Way Ratchet Function
The torque wrench features a two-way ratchet head for easy left/right switching. Use the toggle switch on the wrench head to select the desired direction:
- Leftward Adjustment (Counter-clockwise mode): For loosening fasteners.
- Rightward Adjustment (Clockwise mode): For tightening fasteners.

6. Maintenance
- After each use, return the torque setting to the lowest value (2 N·m) to relieve spring tension and maintain accuracy.
- Clean the wrench and bits with a soft, dry cloth. Do not use harsh chemicals or solvents.
- Store the torque wrench in its protective case in a dry, clean environment.
- Regularly inspect the wrench for any signs of damage or wear.

9. User Tips
- Listen for the Click: The "click" sound is crucial. If you don't hear or feel it, stop immediately. Continuing to apply force can strip bolts or damage components.
- Smooth Application: Apply torque with a smooth, continuous motion rather than sudden jerks to ensure accurate readings and proper engagement of the click mechanism.
- Check Bit Sizes: Always double-check that you are using the correct size bit (Allen or Hex) for the fastener to prevent rounding or stripping. The included bits are clearly marked in millimeters and inches.
- Storage: Storing the wrench at its lowest torque setting helps preserve the calibration of the internal spring.
