•Tighten all fluid connections before operating the equipment.
•Check hoses, tubes, and couplings daily. Replace worn or damaged parts immedi- ately.
TOXIC FLUID OR FUMES HAZARD

Gun Selection
Conventional Guns
Excellent atomization and high production rates typically with some reduction in transfer efficiency.
HVLP Guns
An HVLP gun is a high transfer efficiency gun which limits the air pressure at the air cap to 10 psi (0.07 MPa, 0.7 bar) maximum. In some areas, an HVLP gun is required for compliance with environmental standards.
Compliant Guns
A compliant gun is a high transfer efficiency gun which has been tested to have a transfer efficiency greater than or equal to HVLP guns. The Graco compliant guns have no restrictions on air cap pressures, but the gun inlet pres- sure must remain under the maximum compli- ant pressure shown on pages
