312001B 5
Installation
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 sprayers
require a 230 Vac, 50
Hz, 10A circuit 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:
• 50 ft (15.0 m) 16 AWG (1.0 mm2)
• 100 ft (30.0 m) 14 AWG (1.5 mm2)
Spray gun:ground through connection to a properly
grounded fluid hose and pump.
Fluid supply container:follow local code.
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 conti-
nuity when flushing or reliev-
ing pressure: hold metal part of
the spray gun firmly to the side
of a grounded metal pail, then
trigger the gun.
Thermal Overload
Motor has a thermal overload switch to shut itself down
if overheated. If unit overheats, allow approximately 45
minutes for unit to cool. Once cool, switch will close and
unit will restart.
WLD
WLD
Smaller gauge or longer extension cords may

Install Tip and Guard on Gun
1. Engage trigger lock.
2. Verify tip and guard parts are assembled in order
shown.
3. Screw tip and guard assembly
on gun. Tighten retaining nut.
Spraying Techniques
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 13.
Adjust Spray Pressure
This sprayer is set up for most airless spraying applica-
tions. Details on tip selection, tip wear, coat thickness,
etc. are provided on page 12.
Align setting indicator with function symbol on Pressure
Control knob, page 8.
• Turning knob to right (clockwise), increases
pressure at gun.
• Turning it left (counter-clockwise), decreases
pressure.
• General spraying instructions are provided in
Getting Started with Basic Spraying Techniques
section of this manual, page 14.

Unclogging Spray Tip
To avoid fluid splashback:
• Never pull gun trigger when arrow-shaped handle is
between SPRAY and UNCLOG positions.
• Tip must be pushed all the way into guard.
1. To UNCLOG tip obstruction,
engage trigger lock.
2. Point arrow-shaped handle back-
ward to UNCLOG position.
3. Aim gun at piece of scrap or
cardboard.
4. unlock trigger lock. Pull trigger to
clear clog.
5. When obstruction is cleared,
engage trigger lock and rotate
arrow-shaped handle back to
SPRAY position.
Point the arrow-shaped handle on the spray tip forward
to SPRAY and backward to UNCLOG obstructions.
Tip Selection
Selecting Tip Hole Size
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 13.
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.
• Maximum tip hole sizes supported by the sprayer:
– ProX7: 0.017 in. (0.43 mm)
– ProX9: 0.019 in. (0.48 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.
HINTS:
• Use larger tip hole sizes with thicker coatings and
smaller tip hole sizes with thinner coatings.
• Maximum tip hole sizes supported by sprayer:
– ProX7: 0.017 in. (0.43 mm)
– ProX9: 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 deter-
mines 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, con-
fined 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.

Getting Started With Basic Techniques
14 312001B
Getting Started With Basic Techniques
Use the Practice Spray Board to practice these basic spraying techniques before you begin spraying the surface.
• Hold gun 12 in. (30 cm) from surface and aim
straight at surface. Tilting gun to direct spray angle
causes an uneven finish.
• Flex wrist to keep gun pointed straight. Fanning gun
to direct spray at angle causes uneven finish.
Triggering Gun
Pull trigger after starting stroke. Release trigger before
end of stroke. Gun must be moving when trigger is
pulled and released.
Aiming Gun
Aim tip of gun at bottom edge of previous stroke, over-
lapping each stroke by half.
Spray Shield
Use Sample Spray Shield to help shield ceilings and floor
boards from spray. The Sample Spray Shield is intended
to introduce you to the benefits of a spray shield. Visit
your local paint supplier for larger spray shield solutions.
1. Apply a layer of masking tape
approximately 4 inches wide to
edge of spray shield. Change tape
when paint starts to accumulate
on spray shield.
2. Grasp shield firmly through han-
dle grip with one hand.
3. When spraying, use shield
to prevent paint from getting
on ceiling or adjoining walls.
4. Move the spray shield as
you move the gun to protect
surface.
