5. Operating Instructions
The Klein Tools Torque Screwdriver is designed for precise fastening applications. Follow these steps for optimal use:
- Set the Torque Value: Locate the torque adjustment mechanism on the screwdriver handle. Rotate the adjustment collar to set the desired torque value within the 5-40 in. lbs range. Ensure the desired value aligns with the indicator mark for accuracy.
- Grip the Screwdriver: Hold the screwdriver firmly using the tri-lobular handle. The textured finish provides an enhanced grip and comfort during operation.
- Apply Torque: Place the bit onto the fastener. Apply steady, even pressure and rotate the screwdriver. The tool is designed to click or slip once the set torque value is reached, preventing over-tightening.
