if overheated. If unit overheats, perform Pressure Relief
Procedure, page 9, and allow approximately 45 minutes
for unit to cool before attempting to resume operation.
Power Requirements
• 100-120V units require 100-120 VAC, 50/60 Hz,
15A, 1 phase.
• Use an extension cord with an undamaged ground
contact.
• If an extension cord is necessary, use a 3-wire, 12
AWG (2.5 mm2) minimum.
Pails
•Solvent and oil/based fluids: follow local code.
Use only conductive metal pails, placed on
a grounded surface such as concrete.
• Do not place pail on a nonconductive surface such
as paper or cardboard which interrupts grounding
continuity.
•Grounding a metal pail: connect a ground wire to
the pail by clamping one end to pail and other end to
a true earth ground such as a water pipe.
•To maintain grounding continuity when flushing
or relieving pressure: hold metal part of spray gun
firmly to side of a grounded metal pail. Then trigger
gun.
The equipment must be grounded to reduce the risk
of static sparking and electric shock. Electric or static
sparking can cause fumes to ignite or explode.

Prime and Flush Storage Fluid
Before you use your sprayer for the first time or begin a
new spraying project, you need to prime the sprayer and
flush the storage fluid out of the sprayer.
Oil- or Water-based Materials
• When spraying water-based materials, flush the
system thoroughly with water.
• When spraying oil-based materials, flush the sys-
tem 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 prime 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 flush-
ing solvent first. The solvent flowing out of the prime
tube should not contain any water.
• When flushing with solvents, ground pail and gun.
Read Grounding and Electric Requirements, page
8.
• To avoid fluid splashing back on your skin or into
your eyes, always aim gun at inside wall of pail.
1. Make sure the power switch is OFF and the sprayer
is unplugged.
2. Separate prime tube (smaller) from suction tube
(larger).
3. Place prime tube in waste pail.
4. Submerge suction tube in water or flushing solvent.
5. Turn Prime/Spray Valve to PRIME.
6. Plug sprayer in a grounded outlet.
7. Turn power switch ON.

8. Increase pressure to start motor and allow fluid
to circulate through drain tube for 15 seconds; then
turn pressure down.
9. When sprayer starts pumping, flushing solvent and
air bubbles will be purged from system. Allow fluid to
flow out of prime tube, into waste pail, for 30 to 60
seconds.
10. Turn power switch OFF.
11. Transfer suction tube to paint pail and submerge
suction tube in paint.
12. Turn power switch ON.
13. When you see paint coming out of prime tube:
a. Point gun into waste pail.
b. Unlock gun trigger lock.
c. Pull and hold gun trigger.
d. Turn Prime/Spray valve to SPRAY.
14. Continue to trigger gun into waste pail until you see
only paint coming out of gun.
15. Release trigger. Engage trigger lock.
NOTE: Motor stopping indicates pump and hose are
primed with paint. If motor continues to run the sprayer
is not properly primed. To reprime, turn Prime/Spray
valve to PRIME and repeat step 13.

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.
4. Ensure spray tip arrow is pointed forward to spray
position.
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.
NOTE: If tails persist when spraying at the highest pres-
sure, a smaller tip is needed or the material may need to
be thinned.
Adjust Spray Pressure
This sprayer is set up for most airless spraying applica-
tions.
NOTE: Motor only runs when gun is triggered. Sprayer
is designed to stop pumping when gun trigger is
released.
• Turning knob to right (clockwise), increases pres-
sure at gun.
• Turning it left (counter-clockwise), decreases pres-
sure.
• General spraying instructions are provided in Get-
ting Started section of this manual, page 14.

Getting Started
Use a piece of scrap cardboard to practice these basic
spraying techniques before you begin spraying the sur-
face.
• 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.
Unclogging Spray Tip
Occasionally, debris from material can accumulate and
clog the spray tip. Perform the following steps to unclog
the tip.
1. To unclog tip obstruction, engage trigger lock.
2. Reverse spray tip to UNCLOG position.
NOTE: Trapped pressure in the gun and paint hose may
make the spray tip very difficult to turn. If so, perform the
Pressure Relief Procedure, page 9, before rotating
spray tip.
3. Aim gun at waste area, disengage trigger lock. Pull
trigger to clear clog.
