Air Pressure Verification Kit for HVLP
Guns
NOTE: When using Gun Part No. 243575, with the
239898 Air Cap, the compliant air pressure should be
verified by using Air Pressure Verification Kit 243581
(not to be used for actual spraying). Refer to page 30.
Install the verification kit air cap on the gun. Turn on
the air to the gun, then trigger the gun to read the air
pressure on the gauge. To be HVLP compliant, the air
pressure must not exceed 10 psi (70 kPa, 0.7 bar).
Remove the verification kit air cap and install Air Cap
239898.

Operation
Apply the Fluid
Always hold the gun at a right angle from the surface.
Do not make an arc with the gun as it causes an
uneven coat of fluid. See Fig. 7.
1. To achieve the best results when applying fluid,
keep the gun perpendicular to the surface and
maintain a consistent distance of approximately 8
to 12 inches (200 to 300 mm) from the object
being sprayed. See Fig. 7.
2. To obtain an even finish, use smooth, even strokes
across the object being sprayed with 50% overlap.
3. Paint using parallel strokes. This spray gun applies
all coatings evenly without cross coating.
