Note: To minimize tip wear, it is best to always
strain paint before use with a paint strainer bag
and regularly clean all filters and strainers.
Replace tips before they become excessively
worn. Worn tips waste paint, cause overspray,
make cutting-in difficult, and decrease sprayer
performance.
If the tip is the maximum rated size for your sprayer,
when it wears, it will exceed the flow rate capacity
of the machine. If when using the maximum
capacity tip size the pump cannot keep up, then
you know that the tip is worn beyond capacity.
CLEANUP
At the end of the day, the material in the line should
be recovered and the machine thoroughly cleaned.
This will avoid material drying in the pump or hose.
CAUTION: Under no circumstances allow material
to dry in the pump. If material dries in the pump
and hose, the pump will need to be completely
disassembled and rebuilt and the hose will need
to be discarded and replaced.
1. Relieve pressure in the system according to
the Pressure Relief Procedure.
2.
Remove the tip and tip guard and soak in the
appropriate solvent for the material being
used.
3. Rinse off the suction tube and place in a
bucket of the appropriate flushing solvent
fluid. Usually this will be water (for water-
based materials), mineral spirits (for oil-based
materials) or lacquer thinner ( for lacquers).
Special flushing fluids may be required for
SPRAY TIP SELECTION (See chart 1)
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 orifice size. Generally, use a
smaller orifice 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 flow 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 orifice 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, rate of the spray gun movement, and
distance to surface.)
The numbers on the tip identify its orifice size and
fan width. The first number on the tip identifies 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 orifice size.
SPRAY TIP REPLACEMENT
During use, especially with latex paint, grit and
impurities in the paint under high pressure will
cause the orifice 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.
