AIRLESSCO LP540 - Airless Spray Gun Troubleshooting; Common Spray Gun Defects and Corrections; Testing the Spray Pattern

During use, especially with latex paint, high pressure will
cause the orice to grow larger. This destroys the pattern.
Replace tips before they become excessively worn. Worn
tips waste paint, cause overspray, make cutting-in difcult,
and decreases sprayer performance.
Two tips having the same tip size, but different pattern widths
will deliver the same amount of paint over a different area
(wider or narrower strip). A spray tip with a narrow pattern
width makes it easy to spray in tight places.
Thickness of the paint coat per stroke is determined by spray
tip "fan width", rate of the spray gun movement, and distance
to surface.
SPRAY TIP SELECTION
SPRAY TIP REPLACEMENT PATTERN WIDTH
SPRAY TIP SELECTION
Spray tip size is based on how many gallons of paint per
minute can be sprayed through the tip. Do not use a tip
larger than the maximum pump ow rate or capacity the
sprayer can accommodate. Pump ow rate is measured
in gallons per minute (GPM).
Spray tip selection is based on paint viscosity, paint type,
and job needs. For light viscosities (thin paints), use a
smaller tip; for heavier viscosities (thicker paints), use a
larger tip size.

*Pump will support tip worn to next larger size.
TIP IDENTIFICATION:
1st 3-digits identifies it as a REV-TIP
TM
for airless
paint spraying
(P.N. 560-xxx) or
a REV-TIP
TM
for airless line striping
(P.N. 562-xxxST).
4th digit is the fan width - the number is half the fan width, e.g., 5 means a 10” fan.
5th and 6th digits
are for the orifice size and is measured in thousandths of an inch,
e.g., 17 = 0.017 inch - The higher the number, the larger the tip.
