- Insert the bit firmly into the 1/4" magnetic hex bit holder at the front of the screwdriver. The magnetic holder will secure the bit in place.
Operating Instructions
Setting the Torque Value
The torque screwdriver allows for precise torque settings within its 15-75 in-lb range, with 1 in-lb increments. Follow these steps to set the desired torque:

Image: A four-panel illustration demonstrating how to set the torque: 1. Install the bit, 2. Pull down the tail cap to unlock, 3. Rotate the cap to adjust the torque, 4. Release the cap to lock the setting.
- Unlock: Pull down and hold the Torque Setting Tail Plug (the cap at the end of the handle) to unlock the adjustment mechanism.
- Adjust: While holding the tail plug down, rotate it to align the desired torque value on the scale with the indicator line. The scale shows values from 15 to 75 in-lb.
- Lock: Release the tail plug. It will spring back into place, locking the set torque value. Ensure the cap is fully released and locked before use.

Using the Torque Screwdriver
- With the desired bit installed and torque value set, place the bit into the fastener head.
- Apply steady, even pressure and rotate the screwdriver clockwise (for tightening).
- Continue rotating until you hear and feel a distinct "click." This click indicates that the preset torque value has been reached.
- Stop applying force immediately after the click. Over-tightening beyond the click can damage the fastener or the workpiece.
The VANPO Torque Screwdriver is suitable for various applications, including:

Maintenance
- Cleaning: Wipe the screwdriver and bits with a clean, dry cloth after each use. Do not use harsh chemicals or abrasive cleaners.
- Storage: Store the torque screwdriver and bits in the provided storage case in a dry, temperature-controlled environment. Avoid extreme temperatures and humidity.
- Calibration: For optimal accuracy, it is recommended to have the torque screwdriver calibrated periodically by a qualified service center, especially after heavy use or if accuracy is critical for your application.
- Bit Care: Inspect bits regularly for wear or damage. Replace worn or damaged bits to ensure proper fastener engagement and prevent stripping.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Screwdriver does not click at set torque. | Torque setting is too high for the application; tool is not properly calibrated; incorrect bit size. | Verify the torque setting is appropriate. Ensure the bit is correctly seated and the correct size. Consider professional calibration if accuracy is suspected. |
| Bit slips or strips fastener head. | Incorrect bit size; worn bit; insufficient downward pressure; fastener head is damaged. | Use the correct bit size for the fastener. Replace worn bits. Apply firm, steady downward pressure while turning. Inspect fastener head for damage. |
| Difficulty adjusting torque. | Tail plug not fully pulled down; debris in mechanism. | Ensure the tail plug is fully pulled down before rotating. Clean any visible debris from the adjustment mechanism. |
