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 308–644 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.
