WARNING

FIRE AND EXPLOSION HAZARD

To reduce static sparking and splashing when priming, be sure the spray tip is not installed on the gun, and hold a

metal part of the gun firmly to the side of a grounded metal pail.

7.To prime hose, lower pressure to reduce splash- ing. Holding gun against pail, trigger gun and slowly increase pressure until pump starts. Keep gun triggered until all air is forced out of system and fluid flows freely from gun. Release trigger and engage gun safety latch.

8.Check all fluid connections for leaks. Relieve pressure before tightening any connections.

9.Install spray tip. Engage gun safety latch first! See manual 308644 for how to install tip.

10.Adjust spray pattern

a.Increase pressure just until spray from gun is completely atomized. To avoid excessive overspray and fogging, and to extend tip and sprayer life, always use lowest pressure needed to get desired results.

b.If more coverage is needed, use a larger tip rather than increasing pressure.

c.Test spray pattern. To adjust direction of spray pattern, engage gun safety latch and loosen retaining nut (B). Position tip guard horizontally for a horizontal pattern or vertically for a verti- cal pattern. Hold tip guard in place while tight- ening retaining nut. See Fig. 9.

NOTE: Spray patterns will change as tips wear. Change spray tip if adjusting pressure will not improve spray pattern.
