 Turn HIGH/LOW pressure control from LOW to HIGH until
pump starts.
 Spray into waste container until all air, water, cleaning
fluid is expelled and only paint comes out.
NOTE: When the motor stops, this indicates that the
pump and hoses are under pressure. If the motor con-
tinues to run, re-prime by turning the prime/spray lever
to PRIME.
 Turn lock-off thumbscrew counterclockwise to lock
sprayer trigger.
 Turn ON/OFF switch OFF.
 Replace nozzle tip guard and reversible spray tip onto
pistol-grip sprayer.
 Unit is ready to spray.
SELECTING A SPRAY TIP
See Figure 13, page 18.
Spray tips come in a variety of hole sizes and fan widths.
Your unit includes a reversible spray tip with a hole size of
.015 in. that will work for a wide variety of applications. The
515 spray tip has a fan width of 10-12 in.
HOLE SIZE: Spray tip hole size determines the flow rate,
that is the amount of paint that is discharged from sprayer.
A larger hole size is best for thicker materials. A smaller hole
size is best for thinner materials.
FAN SIZE: Fan width determines the size of the spray pattern
when sprayer is held approximately 12 in. from surface to
be painted.
A narrow fan width will provide thicker coverage of material
and is better suited for small, tight areas.
A wide fan width will give thinner coverage of material and
provide better coverage on large, broad areas.
SPRAY TIP NUMBERS: When selecting a spray tip, the last
three numbers of the spray tip number contains information
on hole size and fan width.
For example if the spray tip number is 515, the 5, when
doubled, is the approximate fan width of paint when applied
12 inches from surface. The last two numbers, 15, refer to
the hole size in inches. In this case .015 in.

SPRAY TIP WEAR: It is important to replace or spray tips
when they become worn. A worn spray tip will cause uneven
application and finish of material. Over time the spray tip hole
size increases and the width of the fan spray decreases.

When using latex paint, spray tips need to be replaced
between 15 and 40 gallons. For oil based materials, replace
spray tips after 35 to 60 gallons of use.
To increase the life of your spray tips, use the lowest pressure
setting needed to apply an even coating of material.
WARNING:
This is a high pressure device. To reduce the risk of injury,
user must read and understand operator's manual. To
reduce the risk of injection do not point sprayer at any
part of the body, persons, or unit itself. In case of skin
injection, seek medical attention immediately. Failure to
heed this may cause serious personal injury.
SPRAYING
See Figure 14, page 18.
 Ensure surface to be painted is free of dust, dirt, and
grease.
 Mask or cover any areas not intended to be painted or
stained. Be aware of wind that may cause your paint or
stain to spray into areas not desired. Always use drop
cloths or other cover to protect areas that are not intended
to be painted or stained.
 Select spray tip and seat securely into nozzle tip guard.
Arrow on spray tip should face direction of spray.
 Plug in the paint station.
 Prime unit. Follow Set Up and Priming instructions.
 Turn ON/OFF switch ON.
 Turn prime/spray lever to SPRAY.
 Turn HIGH/LOW pressure control clockwise to SPRAY
icon (HIGH pressure). Pressure can be adjusted to reach
desired spray pattern and coverage.
 Unlock pistol-grip sprayer trigger. Begin spraying.
NOTE: If spray tip becomes clogged, turn 180° and spray
into waste container to clear clog. Return spray tip to
spray position and continue spraying.
 Lock pistol-grip sprayer trigger and follow release
pressure procedure when finished or stopping for any
reason.
PAINTING TIPS
See Figures 15-16, page 18.
 Practice spraying on a piece of scrap material to test your
spray pattern before beginning. If you cannot get a good
spray pattern see Troubleshooting section.
•
 To create an even coating over the entire surface:
•
• Keep the sprayer an even distance from the area be-
•
ing sprayed, about 12 inches from the spray tip of the
sprayer to the surface being sprayed.
• Operate the sprayer in straight horizontal strokes. Do
not hold the sprayer at an angle. This will result in
uneven coverage.
