have to be increased slightly.
• Hold the gun at a right angle to the working surface and move it parallel.
• Keep the gun about 6-10 inches away from the surface (depending on the
material and operating pressure), see Fig.2.
• Start the stroke before squeezing trigger and release it just after ending the
stroke.
• Always keep the material deposited even and wet.
• Operate at the correct air pressure for a fine finish and safe performance.
Never exceed the maximum operating pressure.

OPERATION
WHY USE HVLP ?
HVLP (High Volume Low
Pressure) spraying
equipment has been
developed as a result of the
introduction of the
Environmental Protection Act
1990. This legislation is aimed at
cutting solvent emissions
produced from both commercial
and car refinish products.
HVLP equipment uses less
air (less the 10psi, 0.69 bar at
the air cap), but with a higher
throughput resulting in more
paint staying on the workpiece
and less being released into the
atmosphere. With traditional
spray guns there is a
tendency for the automized
paint and solvent to bounce off
the workpiece and pollute the
atmosphere.
