The following warnings are for the setup, use, grounding, maintenance, and repair of this
equipment. The exclamation point symbol alerts you to a general warning and the hazard
symbols refer to procedure-specific risks. When these symbols appear in the body of this
manual or on warning labels, refer back to these Warnings. Product-specific hazard symbols
and warnings not covered in this section may appear throughout the body of this manual
where applicable.
GROUNDING
This product must be grounded. In the event of an electrical short circuit, grounding
reduces the risk of electric shock by providing an escape wire for the electric current.
This product is equipped with a cord having a grounding wire with an appropriate
grounding plug. The plug must be plugged into an outlet that is properly installed and
grounded in accordance with all local codes and ordinances.
• Improper installation of the grounding plug is able to result in a risk of electric
shock.
• When repair or replacement of the cord or plug 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 serviceman when the grounding instructions
are not completely understood, or when in doubt as to whether the product is
properly grounded.
• Do not modify the plug provided; if it does not fit the outlet, have the proper outlet
installed by a qualified electrician.
• This product is for use on a nominal 110V or 230V circuit and has a grounding
plug similar to the plugs illustrated in the figure below.

Warnings
WARNING
FIRE AND EXPLOSION HAZARD
Flammable fumes, such as solvent and material fumes, in work area can ignite or
explode. To help prevent fire and explosion:
• Do not spray flammable or combustible materials near an open flame or sources
of ignition such as cigarettes, motors, and electrical equipment.
• Material 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
material or solvent fumes. All parts of the spray system, including the pump, hose
assembly, spray gun, and objects in and around the spray area shall be properly
grounded to protect against static discharge and sparks. Use Graco conductive
or grounded high-pressure airless material sprayer hoses.
• Verify that all containers and collection systems are grounded to prevent static
discharge. Do not use pail liners unless they are anti-static or conductive.
• Connect to a grounded outlet and use grounded extensions cords. Do not use
a 3-to-2 adapter.
• Do not use a material or a solvent containing halogenated hydrocarbons.
• Do not spray flammable or combustible liquids in a confined area.
• Keep spray area well-ventilated. Keep a good supply of fresh air moving through
the area.
• Sprayer generates sparks. Keep pump assembly in a well ventilated area a least
20 feet (6.1 m) from the spray area when spraying, flushing, cleaning, or
servicing. Do not spray pump assembly.
• Do not smoke in the spray area or spray where sparks or flame is present.
• Do not operate light switches, engines, or similar spark producing products in the
spray area.
• Keep area clean and free of material or solvent containers, rags, and other
flammable materials.
• Know the contents of the materials and solvents being sprayed. Read all Safety
Data Sheets (SDSs) and container labels provided with the materials and
solvents. Follow the material and solvents manufacturer’s safety instructions.
• Keep a working fire extinguisher in the work area.
ELECTRIC SHOCK HAZARD
This equipment must be grounded. Improper grounding, setup, or usage of the
system can cause electric shock.
• Turn off and disconnect power cord before servicing equipment.

Grounding
The equipment must be grounded to
reduce the risk of static sparking and
electric shock. An electric or static spark
can cause fumes to ignite or explode. An
improper ground can cause electric shock.
A good ground provides an escape wire for
the electric current.
This product is equipped with a cord having
a grounding wire with an appropriate
grounding plug. The plug must be plugged
into an outlet that is properly installed and
grounded in accordance with all local codes
and ordinances.
Do not modify the plug provided; if it does not
fit the outlet, have the proper outlet installed
by a qualified electrician.
Solvent-Based Materials
NOTE: All hoses sent with the unit are for
water-based material application only.
Solvent compatible hoses and applicators
must be used.
Flush the Equipment
• Flush with a fluid that is compatible with
the fluid being dispensed and the
equipment wetted parts.
• Flush at the lowest pressure possible.
Check connectors for leaks and tighten
as necessary.
1. Follow Pressure Relief Procedure,
page 19.
2. Set pump to lowest possible fluid
pressure, and start pump.
3. Hold a metal part of the gun firmly to a
grounded metal pail. Trigger the gun
until clean solvent dispenses.
Amp Switch
Select 15A or 20A depending on your circuit
rating. 110V units require 100-120 VAC,
50/60 Hz, 15 – 20A, 1 phase
Select 10A or 16A depending on your circuit
rating. 230V units require 220-240 VAC,
50/60 Hz, 10 – 16A, 1 phase
To avoid fire and explosion, always
ground equipment and waste container.
To avoid static sparking and injury from
splashing, always flush at the lowest
possible pressure.
Flush before changing materials, before
•

smooth, lump-free consistency.
3. Make certain all dry powder clumps are
mixed throughly before pouring mixture
into the sprayer hopper.
NOTICE
Failure to make certain that all dry powder
is throughly mixed may cause tip or pump
clogging.
