hole size.
Reference
Spray Tip Selection
Spray tips come in a variety of hole sizes for
spraying a range of fluids. Your sprayer
includes a tip for use in most paint spraying
applications. Use the coatings table on page
14 to determine the range of recommended
tip hole sizes for each fluid type. If you need
a tip other than the one supplied, see How to
Spray, page 14.
NOTE: For proper sprayer operation use only
a tip from the same tip family that came with
your sprayer.
Hints:
•
As you spray, the tip wears and
enlarges. Starting with a tip hole size
smaller than the maximum will allow you
to spray within the rated flow capacity of
the sprayer.
•Use larger tip hole sizes with thicker
coatings and smaller tip hole sizes with
thinner coatings.
•Tips wear with use and need periodic
replacement.
•Tip hole size controls flow rate - the
amount of paint that comes out of the
gun.
Fan Width
Fan width is the size of the spray pattern,
which determines the area covered with each
stroke.
Hints:
•
Select a fan width best suited to the
surface being sprayed.
•Wider fans provide better coverage on
broad, open surfaces.
•Narrower fans provide better control on
small, confined surfaces.
Understanding Tip Number
The last three digits of tip part number (i.e.:
) contains information about hole size
xxx412
and fan width on surface when gun is held 12
in. (30.5 cm) from surface being sprayed.
263A4433D
First digit when doubled = approximate fan width.
Last two digits = tip hole size in thousands of an inch.
For an 8 to 10 in. (203 to 254 mm) fan width and 0.010
(0.25 mm) hole size, order Part No.

Oil- or Water-Based Materials
•
When spraying water-based materials,
flush the system thoroughly with water.
•When spraying oil-based materials,
flush the system thoroughly with mineral
spirits or compatible, oil-based flushing
solvent.
•To spray water-based materials after
spraying oil-based materials, flush the
system thoroughly with water first. The
water flowing out of drain tube should
be clear and solvent-free before you
begin spraying the water-based material.
•To spray oil-based materials after
spraying water-based materials, flush
the system thoroughly with mineral spirits or a compatible oil-based flushing
solvent first. The solvent flowing out of
the drain tube should not contain any
water. When flushing with solvents
always follow Static Grounding Instructions (Oil-Based materials),
page 27.
•To avoid fluid splashing back on your
skin or into your eyes, always aim gun at
inside wall of pail.
The equipment must be grounded to
reduce the risk of static sparking and
electric shock. An electric or static spark
can cause fumes to ignite or explode. An
improper ground can cause electric shock.
A good ground provides an escape wire for
the electric current.
Always use a metal pail for oil-based
materials requiring flushing with compatible
oil-based flushing solvents when sprayer is
flushed or pressure is relieved.
Follow local code. Use only conductive metal
pails, placed on a grounded surface such as
concrete.
Do not place pail on a non-conductive surface
such as paper or cardboard which interrupts
grounding continuity.

Cleaning Outlet Valves
Dirt and debris in the outlet valve assemblies
may affect sprayer performance and require
cleaning.
1.To clean the three outlet valves, remove
two pump plugs and front valve. Remove
pump plugs with 8mm or 5/16” Allen
wrench.
Do not push outlet valves all the way into
the valve plugs or front valve. If outlet
valves are pushed all the way into the valve
plugs or front valve the sprayer will spray
with reduced performance.
