this manual. Be familiar with the controls and the proper
usage of the equipment.
READ ALL INSTRUCTIONS
KNOW YOUR POWER TOOL. Read the operator’s
manual carefully. Learn the machine’s applications and
limitations as well as the specific potential hazards related
to this tool.
WARNING: To reduce the risk of fire or explosion:
Do not spray flammable or combustible materials near
an open flame or sources of ignition such as cigarettes,
motors, and electrical equipment.
For units intended for use with only water-based or
mineral spirit-type materials with a minimum flash point
of 140°F (60°C), do not spray or clean with liquids
having a flash point less than 140°F (60°C).
Paint or solvent flowing through the equipment is able
to result in static electricity. Static electricity creates
a risk of fire or explosion in the presence of paint or
solvent fumes. All parts of the spray system, including
the pump, hose assembly, pistol-grip sprayer, and
objects in and around the spray area shall be properly
grounded to protect against static discharge and
sparks.
Use only conductive or grounded high-pressure airless
paint sprayer hoses specified by the manufacturer.

GROUNDING INSTRUCTIONS
This product must be grounded. In the event of a malfunction
or breakdown, grounding provides a path of least resistance
for electric current to reduce the risk of electric shock.
This product is equipped with an electric cord having an
equipment-grounding conductor and a grounding plug. The
plug must be plugged into a matching outlet that is properly
installed and grounded in accordance with all local codes
and ordinances.
Do not modify the plug provided. If it will not fit the outlet,
have the proper outlet installed by a qualified electrician.
WARNING:
Improper connection of the grounding plug can result in a
risk of electric shock. When repair or replacement of the
cord is required, do not connect the grounding wire to
either flat blade terminal. The wire with insulation having
an outer surface that is green with or without yellow
stripes is the grounding wire.
Check with a qualified electrician or service personnel if
the grounding instructions are not completely understood,
or if in doubt as to whether the product is properly
grounded.
Repair or replace a damaged or worn cord immediately.
This product is for use on a nominal 120 V circuit and has
a grounding plug similar to the plug illustrated below. Only
connect the product to an outlet having the same configuration
as the plug. Do not use an adapter with this product.
WARNING:
Check extension cords before each use. If damaged
replace immediately. Never use the product with a
damaged cord since touching the damaged area could
cause electrical shock resulting in serious injury.
ELECTRICAL CONNECTION
This product is powered by a precision-built electric motor. It
should be connected to a power supply that is 120 V, AC only
(normal household current), 60 Hz. Do not operate this
product on direct current (DC). A substantial voltage drop
will cause a loss of power and the motor will overheat. If
the product does not operate when plugged into an outlet,
double check the power supply.

SELECTING A SPRAY TIP
See Figure 11.
Spray tips come in a variety of hole sizes and fan widths.
Your unit includes two reversible spray tips with a hole size
of .010 in. and .019 in. that will work for a wide variety of
applications. The 310 spray tip has a fan width of 6-8 in. and
is best for fine finish applications. The 619 spray tip has a fan
width of 12-14 in. and is best for airless applications.
HOLE SIZE: Spray tip hole size determines the flow rate,
which 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 contain information
on hole size and fan width.
For example, if the spray tip number is 1415, the 4, 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 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 of use. 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.
