Fluid supply container: follow local code.
Grounding and Electric
Requirements
Sprayer must be grounded. Grounding
reduces the risk of static and electric shock by
providing an escape wire for electrical current
due to static build up or in the event of a short
circuit.
The 120 Vac sprayers require a 120
Vac, 60 Hz, 15A circuit with a grounding receptacle. The
230 Vac Model
247328 requires
230 Vac, 50 Hz, 10A with a grounding receptacle, Never use an outlet that is not grounded or
an adapter.
Do not use the sprayer if the
electrical cord has a damaged
ground prong.
Only use an extension cord
with an undamaged 3-prong
plug. Recommended extension cords for use with this
sprayer:
• 25 ft (7.6 m) 18 AWG (1.0 mm2)
• 50 ft (15.2 m) 16 AWG (1.0 mm2)
• 100 ft (30.5 m) 14 AWG (1.5 mm2)
• 150 ft (45.7 m) 12 AWG (2.5 mm2)
WLD
WLD
Solvent pails used when flushing: follow
local code. Use only conductive metal pails,
placed on a grounded surface such as concrete. Do not place the pail on a nonconductive
surface, such as paper or cardboard, which
interrupts grounding continuity.
Grounding the metal pail: connect a ground
wire to the pail by clamping one end to pail and
other end to ground such as a water pipe.
Maintaining grounding continuity when
flushing or relieving
pressure: hold metal
part of the spray gun
firmly to the side of a
grounded metal pail,
then trigger the gun.
TIA
Thermal Overload
Motor has a thermal overload switch to shut
itself down if overheated.
To reduce risk of injury from motor starting unexpectedly when it cools, always turn power switch
OFF if motor shuts down.
Spray gun: ground through connection to a
properly grounded fluid hose and pump.
Smaller gauge or longer extension cords
may reduce sprayer performance.

Selecting Tip Hole Size
HINTS:
Tips come in a variety of hole sizes for spraying a range of fluids. Your sprayer includes an
0.015 in (0.38 mm) tip for use in most spraying
applications. Use the following table to determine the range of recommended tip hole sizes
for each fluid type. If you need a tip other than
the one supplied, see the Reversible Tip
Selection Chart on page 14.
•
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.
•
Maximum tip hole sizes supported by the
sprayer:
– dx: 0.015 in. (0.38 mm)
– XR5: 0.015 in. (0.38 mm)

Choosing the Correct Tip for
the Job
Consider coating and surface to be sprayed.
Make sure you use best tip hole size for that
coating and best fan width for that surface.
Tip Hole Size
Tip hole size controls flow rate - the amount of
paint that comes out of the gun.
14
HINTS:
• Use larger tip hole sizes with thicker coatings and smaller tip hole sizes with thinner
coatings.
• Maximum tip hole sizes supported by
sprayer:
– dx: 0.015 in. (0.38 mm)
– XR5: 0.015 in. (0.38 mm)
– XR7: 0.017 in. (0.43 mm)
– XR9: 0.019 in. (0.48 mm)
• Tips wear with use and need periodic
replacement.
Fan Width
Fan width is the size of the spray pattern,
which determines the area covered with each
stroke. Narrower fans deliver a thicker coat,
and wider fans deliver a thinner coat.
HINTS:
• Select a fan width best suited to the surface
being sprayed.
• Wider fans allow 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 number (i.e.:
221413) contain information about hole size
and fan width on surface when gun is held 12
in. (30.5 cm) from surface being sprayed.

Spraying Techniques
Spraying Techniques
This sprayer is set up for most airless spraying
applications. Details on tip selection, tip wear,
coat thickness, etc. are provided on page 13.
Motor only runs when gun is triggered.
Sprayer is designed to stop pumping when
gun trigger is released.
Preventing Excessive Tip
Wear
•
•
•
Spray should be atomized (evenly distributed, no gaps at edges). Start at low pressure setting, increase pressure a little at a
time until you see a good spray pattern,
without tails.
Spray at lowest pressure that atomizes
paint.
If maximum sprayer pressure is not enough
for a good spray pattern, tip is too worn.
See Reversible Spray Tip Selection Chart,
page 14.
Adjusting Pressure
Align arrow on sprayer with function symbol on
Pressure Control knob, page 11.
• Turning knob to right (clockwise)
increases pressure at gun.
• Turning it left (counter-clockwise)
decreases pressure.
Getting Started With Basic
Techniques
Practice spraying on a piece of scrap or
cardboard before you begin spraying.
