Grounding Instructions
Grounding Instructions
(Oil-Based or Flammable Materials)
Fluid hoses: Use only electrically conductive
hoses with a maximum of 300 ft. (91 m)
combined hose length to ensure grounding
continuity.
The equipment must be grounded to reduce the
risk of static sparking. A static spark can cause
fumes to ignite or explode. A good ground
provides an escape wire for the electric current.
Spray gun: Grounded through connection to a
properly grounded fluid hose and pump.
Pails
Oil-based or flammable fluids: follow local
codes and regulations. 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.
The sprayer is equipped with a grounding wire
and clamp. The clamp must be connected to a
true earth ground when spraying or flushing
oil-based or flammable materials, see
Important Grounding Information, page 5.
A water pipe can be used as a true earth
ground. Connect the grounding wire and clamp
to a metal water pipe.
A properly grounded electrical outlet can also
be used as a true earth ground. Use the
provided outlet adapter.
Plug the adapter in to a grounded outlet.
Connect the grounding wire and clamp to the
metal stud on the adapter. If the ground wire is
not long enough to reach a grounded electrical
outlet, use a 3-wire grounded extension cord
between the adapter and outlet.
Always ground a metal pail: connect a
ground wire to the pail. Clamp one end to the
pail and the other end to a true earth ground
such as a water pipe.

Turn pressure control knob to START
position. When spraying oil-based or
flammable materials, follow Grounding
Instructions, page 11.
2.
Disengage trigger lock.
Adjust Pressure Control
To select a setting, align symbol on pressure control knob with setting indicator on sprayer.
1. For best spray results with lowest overspray, adjust pressure control to “START” setting.
2. Test the spray pattern on a test area or piece of cardboard.
3. If needed, increase Pressure Control Knob setting to minimum setting that results in an acceptable
spray pattern.
Spray Pattern Quality
A good spray pattern is evenly distributed as it hits
the surface.
•
•
•
•

Spray should be atomized (evenly
distributed, no gaps at edges).
Increase Pressure Control Knob setting if
needed until spray is even and without gaps
at edges.
Spray Tip may be worn or a smaller tip may
be needed. See Spray Tip and Pressure
Selection, page 22.
Material may need to be thinned. If material
needs to be thinned follow manufacturer’s

Spray Techniques
Use a piece of scrap cardboard 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.
Aim Gun
Aim center of spray of gun at bottom edge of
previous stroke, overlapping each stroke by
half.
Align Spray Pattern
High-pressure spray is able to inject
toxins into the body and cause serious
bodily injury. Do not stop leaks with hand
or rag.

Spray Tip and Pressure Selection
Spray Tips come in a variety of sizes for
spraying a wide range of materials. Your
sprayer includes a 515 Spray Tip for use with
most paints on large surfaces such as walls
and ceilings. If you are spraying stain or need
a different spray fan width, refer to the Spray
Tip chart below to select the best Spray Tip
for your project. Additional Spray Tip sizes
are available where paint sprayers are sold.
1.
2.
Tip Number Calculation:
•
•
The first digit is half of the fan width
(#5 x 2 = 10 inch fan width).
The last two digits are the size of the
tip opening in thousandths of an
inch.
What material are you spraying?
•
The thicker the material, the larger
Spray Tip size you will need.
What spray fan width is needed for your
project?
•
•
Narrow spray fan for smaller
projects
Wider spray fan for larger projects
