2. Safety Instructions
Always observe basic safety precautions to reduce the risk of personal injury and damage to the equipment. Failure to follow these instructions may result in serious injury or property damage.
- Ventilation: Always operate the spray gun in a well-ventilated area to prevent the accumulation of hazardous fumes.
- Personal Protective Equipment (PPE): Wear appropriate safety glasses or goggles, a respirator mask, and protective gloves to prevent exposure to paint fumes and overspray.
- Flammable Materials: Do not spray flammable materials near open flames, pilot lights, or other ignition sources. Ensure proper grounding.
- Pressure: Never exceed the maximum recommended operating pressure. Always disconnect the air supply before cleaning, adjusting, or servicing the gun.
- Children and Pets: Keep the spray gun and all painting materials out of reach of children and pets.

3. Package Contents
Verify that all items are present and undamaged upon unpacking:
- K-3 Mini Air Spray Paint Gun
- Aluminum 4oz Gravity Feed Cup
- Case
4. Setup
Follow these steps to prepare your spray gun for use:
- Connect Air Supply: Attach a 1/4" air hose (not included) to the air inlet port at the bottom of the spray gun handle. Ensure a secure, leak-free connection.
- Attach Gravity Feed Cup: Screw the aluminum 4oz gravity feed cup onto the top port of the spray gun. Hand-tighten only to prevent damage.
- Prepare Paint: Mix your paint according to the manufacturer's instructions. Ensure the paint is properly thinned and strained to remove any particles that could clog the nozzle.
- Fill Cup: Pour the prepared paint into the gravity feed cup. Do not overfill.
- Adjust Air Pressure: Connect the air hose to an air compressor. Set the air compressor regulator to an operating pressure between 20-40 PSI. Start with a lower pressure and adjust as needed for your specific paint and desired finish.
5. Operating Instructions
Proper technique is crucial for achieving a smooth and even finish.
- Test Spray: Before spraying your actual workpiece, perform a test spray on a piece of scrap material. This allows you to adjust the air pressure and fluid flow for the desired pattern and coverage.
- Distance: Hold the spray gun approximately 6-8 inches (15-20 cm) from the surface. Adjust this distance based on the paint type and desired spray pattern.
- Movement: Move the spray gun in smooth, even strokes, keeping it perpendicular to the surface. Overlap each stroke by about 50% to ensure even coverage.
- Trigger Control: Depress the trigger fully for consistent paint flow. Release the trigger at the end of each stroke to avoid excessive paint buildup.
- Multiple Coats: Apply multiple thin coats rather than one thick coat. Allow adequate drying time between coats as recommended by the paint manufacturer.
6. Maintenance and Cleaning
Thorough cleaning after each use is essential for maintaining the performance and longevity of your spray gun.
- Disconnect Air: Always disconnect the air supply before cleaning or performing any maintenance.
- Empty Cup: Empty any remaining paint from the gravity feed cup.
- Flush with Solvent: Pour an appropriate cleaning solvent (e.g., paint thinner for oil-based paints, water for water-based paints) into the cup. Spray the solvent through the gun until it runs clear.
- Clean Cup: Remove the cup and clean it thoroughly with solvent and a brush.
- Disassemble Nozzle: Carefully remove the air cap, fluid nozzle, and needle. Clean these components with a small brush and solvent. Be careful not to damage the delicate parts.
- Clean Gun Body: Wipe down the exterior of the gun body. Do not immerse the entire gun in solvent.
- Reassemble: Once all parts are clean and dry, reassemble the gun. Ensure all components are tightened correctly but do not overtighten.
- Lubrication: Apply a small amount of spray gun lubricant to the needle packing and trigger pivot points periodically.
7. Troubleshooting
Refer to the table below for common issues and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Poor spray pattern / Uneven coverage | Incorrect air pressure; Paint too thick; Clogged nozzle/air cap; Damaged nozzle/air cap. | Adjust air pressure; Thin paint; Clean nozzle/air cap; Replace damaged parts. |
| No paint flow | Clogged fluid nozzle; Needle not retracting; Empty paint cup. | Clean fluid nozzle; Check needle movement; Refill paint cup. |
| Paint leaking from air cap | Loose fluid nozzle; Damaged fluid nozzle; Needle packing worn. | Tighten fluid nozzle; Replace fluid nozzle; Replace needle packing. |
| Excessive overspray | Air pressure too high; Gun too far from surface; Paint too thin. | Reduce air pressure; Move gun closer; Thicken paint. |
