4. Setup
4.1 Connecting to Air Supply
- Ensure your air compressor is capable of providing a stable working pressure of 6.2 kg/cm² (90 PSI).
- Attach an air hose (not included) to the 6.35mm (1/4 inch) inlet connector at the base of the screwdriver handle. Ensure a secure, leak-free connection.
- It is recommended to use an in-line air filter/lubricator to ensure clean, lubricated air supply, which prolongs tool life.

5.4 General Operation
- Select the appropriate screwdriver bit for the fastener.
- Set the desired rotation direction (CW for fastening, CCW for unfastening).
- Adjust the torsion setting if necessary.
- Position the bit onto the fastener head.
- Press the safety switch to start the tool and apply steady, even pressure.
- Release the safety switch once the fastener is secured or removed.
