Disposal
ALWAYS
make sure that the spray gun is cleaned immediately after every use. Delayed or
inadequate cleaning of the spray gun will cause blockages and affect the performance of the
product in the future.
ALWAYS
disconnect the spray gun from the air supply before attempting to clean or
perform maintenance.
ALWAYS
follow the paint manufacture’s recommendations for cleaning, solvent and
disposal.
Cleaning the spray gun cup
1. Make sure any solvent used is recommended by the paint manufacturer.
2. Remove the cup, as well as any tubes.
3. Scrape the paint out of the cup carefully. Dispose of this excess paint properly.
4. Clean the cup with the solvent.
5. Allow to dry.
Cleaning the spray gun
1. Flush the spray gun through with clean solvent.
2. To wash off any paint that has accumulated on the spray gun use a bristle brush and
solvent.
3. With a dampened solvent rag wipe the outside of the spray gun.
4. Allow to dry.
Air nozzle, fluid nozzle and needle assembly
1. To clean the nozzles soak them in solvent to dissolve any dried material then blow the
clean with air. Carefully handle all nozzles and do not make any alterations to the gun.
2. If you need to probe the holes in the nozzles, do not use metal instruments. Always
ensure you use a tool that is softer than brass.
3. Adjust the fluid needle valve so that when the gun is triggered airflow occurs before fluid
flow.
1. Always take care when re-assembling the spray gun. Avoid cross-threading by screwing
the parts hand tight. If a part cannot easily be turned by hand, check that you have the
correct part, or unscrew, realign and try again. DO NOT use excessive force when
re-assembling.
2. If you change the nozzle size, ensure the complete nozzle set is exchanged. Before
putting the paint needle in, insert the paint nozzle.
