Usage
:Usage :
Check the Equipment :
- Ensure the spray gun, air hose, and compressor are compatible.
- Inspect all parts for damage, wear, or clogging.
Select the Right Nozzle :
- Choose the correct nozzle size for your material (paint, lacquer, etc.).
- Refer to the manufacturer's chart for viscosity vs. nozzle size.
Mix the Material :
- Properly mix and strain paint or coating to remove impurities.
- Thin the material according to the product requirements and spray gun capacity.
Fill the Cup :
- Pour the material into the gun’s cup. Do not overfill.
- Secure the lid or cap tightly to avoid spills or pressure loss.
Connect to Air Supply :
- Attach the air hose to the gun and compressor.
- Set the air pressure (usually between 2.5–4 bar or 35–60 psi depending on the spray pattern and material).
Spraying Operation
Test First :
- Spray on a test surface to adjust spray pattern, fluid flow, and fan control.
- Fine-tune air and fluid knobs for desired atomization and coverage.
Maintain Correct Distance :
- Hold the gun about 6–8 inches (15–20 cm) from the surface.
- Move the gun parallel to the surface with smooth, even strokes.
Trigger Control :
- Press the trigger in stages: air first, then material.
- Release in reverse: material off first, then air.
Overlap Strokes :
- Use 50% overlap for even coating without streaks or thin spots.
After Use – Shutdown Procedure
- Turn off the compressor and release air pressure.
- Empty any remaining paint from the cup.
- Clean the spray gun immediately after use (see cleaning below).
Daily Maintenance (After Each Use)
Disassemble & Clean :
- Remove the nozzle, needle, air cap, and cup.
- Use recommended solvents to clean internal and external parts.
- Use soft brushes or specialized spray gun cleaning kits.
Avoid Damage :
- Do not use sharp objects or metal brushes that may damage components.
- Do not soak plastic or rubber parts in aggressive solvents.
Lubricate :
- Apply a few drops of spray gun lubricant to moving parts (trigger, needle packing) to maintain smooth operation.
Weekly or Regular Maintenance
Inspect Components :
- Check seals, O-rings, and gaskets for wear or damage.
- Replace worn-out parts immediately to avoid leaks or spray inconsistencies.
Check Air Passages :
- Blow compressed air through the air channels to prevent blockages.
Test Spray Pattern :
- Ensure consistent, even spray without spitting or pulsating.
Storage Guidelines
- Store the spray gun in a protective case or clean area.
- Keep away from moisture and dust to prevent corrosion and contamination.
- Ensure all parts are dry and clean before storage.
