1. Adjusting the Jaw Opening: Rotate the worm gear (knurled wheel) located between the fixed and movable jaws. Turning the worm gear clockwise will close the jaws, and turning it counter-clockwise will open them.
2. Reading the Scale: The wrench head features a clear scale marked in millimeters (0-37mm). Align the edge of the movable jaw with the desired measurement on the scale for accurate sizing.
3. Securing the Fastener: Once the jaws are adjusted to the correct size, position the wrench head firmly onto the fastener. Ensure a snug fit to prevent rounding the fastener or slippage during use.
4. Applying Torque: Use your torsion wrench handle to apply the necessary torque. The adjustable head allows for flexibility in accessing fasteners in various orientations.

4. Maintenance

Proper maintenance ensures the longevity and optimal performance of your adjustable wrench head.

• Cleaning: After each use, wipe the wrench head clean with a dry cloth to remove dirt, grease, or debris. For stubborn grime, a mild detergent and water can be used, followed by thorough drying.
• Lubrication: Periodically apply a small amount of light machine oil to the worm gear mechanism to ensure smooth adjustment and prevent corrosion.
• Storage: Store the wrench head in a dry environment to prevent rust. Avoid exposure to excessive moisture or corrosive chemicals.
• Inspection: Regularly inspect the wrench head for any signs of wear, damage, or deformation. Discontinue use if any significant damage is observed.

5. Troubleshooting

If you encounter issues with your LiebeWH Adjustable Wrench Head, consider the following:

• Difficulty Adjusting Jaws: Ensure the worm gear is clean and free of debris. Apply a small amount of lubricant if movement is stiff.
• Wrench Head Not Securing to Handle: Verify that your torsion wrench handle has the correct 9x12mm square socket interface. Ensure there is no obstruction in the socket or on the wrench head's interface.
• Slippage on Fastener: Ensure the jaws are adjusted tightly to the fastener. Avoid using the wrench on fasteners that are severely rounded or damaged.
