4. Setup
4.1. Connecting to Air Supply
- Ensure your air compressor is capable of providing the required air pressure and volume (refer to specifications).
- Connect a suitable air hose (minimum 3/8" I.D.) to the air inlet of the drill. It is recommended to use an in-line air filter/lubricator unit to ensure clean, lubricated air supply.
- Secure all connections to prevent air leaks.
- Set the air compressor regulator to the recommended operating pressure.
4.2. Installing Drill Bits (Keyless Chuck)
- Ensure the air supply is disconnected from the drill.
- Rotate the chuck collar counter-clockwise to open the chuck jaws.
- Insert the drill bit fully into the chuck, ensuring it is centered.
- Rotate the chuck collar clockwise to tighten the jaws firmly around the drill bit. Hand-tighten only; do not use tools to overtighten.
- Verify the bit is securely held before reconnecting the air supply.

5. Operating Instructions
5.1. Starting and Stopping
- To start the drill, depress the trigger. The speed is controlled by the amount of trigger depression.
- To stop the drill, release the trigger.
5.2. Reversible Function
The drill features a reversible function for driving screws or extracting bits. The direction control is a thumb switch located above the motor housing.
- Push the switch to the left for forward (clockwise) rotation.
- Push the switch to the right for reverse (counter-clockwise) rotation.
- Always ensure the drill has come to a complete stop before changing the direction of rotation.
5.3. Drilling Techniques
- Always apply steady, even pressure. Do not force the drill, allow the tool to do the work.
- For drilling into metal, use a center punch to mark the drilling point to prevent the bit from wandering.
- Use appropriate drill bits for the material being drilled.
- Clear chips regularly, especially when drilling deep holes, to prevent overheating and binding.
- When drilling through thin materials, place a scrap piece of wood underneath to prevent splintering or tearing.

- If using an in-line lubricator, ensure it is filled with air tool oil and adjusted correctly.
6.2. Cleaning and Storage
- Clean the exterior of the drill with a damp cloth. Do not use harsh solvents.
- Store the drill in a dry, secure location, away from direct sunlight and extreme temperatures.
- If storing for an extended period, apply a light coat of oil to metal parts to prevent corrosion.
6.3. Chuck Maintenance
- Periodically inspect the chuck jaws for wear or damage. Replace if necessary.
- Keep the chuck jaws clean and free of debris to ensure proper gripping of drill bits.
