5. For an even finish, cover your work using smooth even strokes and a 50% overlap.
Note: This HVLP Industrial Spray Gun will not blotch or model when using any coating.
Note: During operation, periodically check that the Yoke (#39) is securely fastened to the
Cup (#47). The Cup Lever (#40) must be securely tightened to the left.
Note: If you are unsatisfied with the results, check the Troubleshooting section further down
this page.
Pattern Control
This Spray Gun will spray three jet shapes and two different fan sizes. Never attempt to
adjust the jet shape or fan size when firing the Spray Gun. Keep your hand away from
the Trigger (#8) while adjusting jet shape or fan size.
1. To adjust the fan size, turn the Retainer Ring (#1). Screw the Retainer Ring (#1) in, to
widen the spray, and screw it out, to narrow the pattern. Unscrew a maximum of one
thread!
2. The Air Cap (#2) adjusts the jet shape. Hold the Spray Gun in firing position (perpendicu-
lar to the ground). Turn the Air Cap (#2) parallel to the ground for a vertical jet. For a hoizontal
jet, turn the Air Cap (#2) perpendicular to the ground. For a round jet, affix the Air Cap (#2)
halfway between the two at a 45 degree angle to the ground.
