IMPORTANT: Before using for the first 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.

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 efficiencies and more overspray.

This translates to a significant 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.
