IMPORTANT: Before using for the rst time, the spray gun must be cleaned
using a solvent based thinner. If not removed, the red oil used by the
manufacturer for testing and corrosion protection may contaminate paint.
IMPORTANT: The Spray Gun must be cleaned immediately after use.
Improper cleaning is a common reason for the Spray Gun not to work.
FIGURE 2
A Comparison: Conventional versus HVLP Spray Guns
Because conventional spray guns require a much higher air cap pressure to atomize
the paint than HVLP Spray Guns, conventional guns have lower transfer efciencies
and more overspray.
This translates to a signicant paint/material savings for HVLP guns, in addition to
making them more environmentally friendly.
To qualify as HVLP, the dynamic air pressure going in the Air Cap must be a maximum
of 10 PSI. The lower the air pressure, the less bounce back and overspray.
Note: Due to the viscosity of latex and other water-based paints, they are not
recommended for use with this or other HVLP (High Volume Low Pressure) spray-
ers.
