rate of the spray gun movement, and
distance to surface.)
The numbers on the tip identify its orice size
and fan width. The first number on the tip
identies the fan width radius in inches. The
last two numbers identify the orifice size in
thousandths of an inch. So, for example, a
517 tip would have a 10 inch fan width (5
inch radius) and a 0.017 inch orice size.
SPRAY TIP REPLACEMENT
During use, especially with latex paint,
grit and impurities in the paint under high
pressure will cause the orice to grow larger
from wear and for the fan pattern width to
degrade.
It is easy to determine the state of wear
of the tip by observing the fan pattern. As
the tip wears, the fan width will become
narrower. A new tip will have a pattern
shaped like a narrow long rounded-corner
rectangle. As it wears it will turn into an
oval shape. When it is completely worn
out it sprays a circle. When the fan width
decreases to about 2/3 of its original size, it is
considered worn out.
Note: To minimize tip wear, it is best to
CLOGGED FLAT TIP
If you are using a flat tip and the spray tip
becomes clogged, relieve pressure from
hose by following the "PRESSURE RELIEF
PROCEDURE." Secure gun with the safety
latch, take off guard, take out the tip, soak
in appropriate solvent & clean with a soft
brush. (Do not use a needle or sharp pointed
instrument to clean the tip. The tungsten
carbide is brittle and can chip.)
SPRAY TIP SELECTION
Spray tip selection is based on paint viscosity,
paint type, and job needs. There are two
variables to identify the tip: orifice size and
fan pattern width. The main variable is tip
orice size. Generally, use a smaller orice tip
For light viscosities (thin materials, like varnish),
and use a larger orifice tip for heavier
viscosities (thicker materials, like latex paints).
Spray tip orifice 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 flow rate or capacity
the sprayer can accommodate. Pump ow
rate is measured in gallons per minute
(GPM) and liters per minute (LPM).
The other variable is the fan pattern width.
Two tips having the same orice tip size,
but different fan widths will deliver the same
amount of paint over a different area (wider
or narrower strip). A spray tip with a narrow
fan width makes it easy to spray in tight
places. (Thickness of the material coat per
stroke is determined by spray tip fan width,
