Warnings
The following are general warnings related to the setup, use, grounding, maintenance and repair of this equipment.
Additional, more specific warnings may be found throughout the body of this manual where applicable. Symbols
appearing in the body of the manual refer to these general warnings. When these symbols appear through the
manual, refer back to these pages for a description of the specific hazard.
Warnings
Fire and Explosion Hazard
Improper grounding, poor ventilation, open flames or sparks can cause a hazardous condition and result
in fire or explosion and serious injury.
• The system is for use with water-based materials only. Only use fluids compatible with the
equipment. Refer to Technical Data of all equipment manuals. Read fluid and solvent manufacturers
warnings.
• Ground the equipment. See Grounding and Electrical Requirements, page 6.
• If there is any static sparking or you feel an electric shock while using this equipment, stop spraying
immediately. Do not use the equipment until you identify and correct the problem.
• Keep work area free of debris, including solvent, rags and gasoline.
• Comply with all applicable state and national fire, electrical and safety regulations.
Equipment Misuse Hazard
Equipment misuse can cause equipment to rupture, malfunction, or start unexpectedly and cause serious
injury.
• Before operating this equipment, read all manuals, tags, and labels including material labels and
instructions.
• Do not expose system to rain. Always store system indoors.
• Do not alter or modify equipment.
• Do not spray cementitious materials.
• Do not exceed maximum working pressure of lowest rated component in your system.
• Check equipment daily. Repair or replace worn or damaged parts immediately.
• To reduce risk of serious injury, including electric shock and splashing fluid in eyes, follow Pressure
Relief Procedure on page 6 before servicing the unit.
• Do not use hoses to pull equipment.
• Route hoses away from traffic areas, sharp edges, moving parts and hot surfaces.
• Do not expose Graco hoses to temperatures above 130 °F (55 °C) or below -35 °F (-37 °C). Store
hazardous fluid in an approved container. Dispose of hazardous fluid according to all local, state and
national guidelines.
• Never directly inhale compressed air. Compressed air may contain toxic vapors.

Warnings
311764D 3
Electric Shock Hazard
To reduce the risk of electric shock:
• Be sure sprayer is adequately grounded through electrical outlet.
• Use only 3-wire, extension cords.
• Make sure ground prongs are intact on sprayer and extension cords. Improper installation of ground-
ing plug will result in a risk of electrical shock, fire or explosion that could cause serious injury or
death.
• Do not operate with cover removed.
• Turn off sprayer. Follow Pressure Relief Procedure, page 6, and unplug unit, before removing any
parts.
Pressurized Equipment Hazard
Fluid from gun, leaks or ruptured components can splash in the eyes or on skin and cause serious injury.
• Follow Pressure Relief Procedure, page 6 when you stop spraying and before cleaning, checking
or servicing.
• Do not point spray gun at anyone; put hand, fingers or rag over nozzle, or stop or deflect leaks with
your hand, body, glove, or rag.
• Wear protective clothing, gloves, and eyewear.
Cleaning Solvent Hazard with Plastic Parts
Use only compatible water-based solvents to clean plastic structural or pressure-containing parts. Many
solvents can degrade plastic parts to the point where they could fail. Such failure could cause serious
injury or property damage. See Technical Data on page 16 of this instruction manual and in all other
equipment manuals. Read fluid and solvent manufacturer’s warnings.
Burn Hazard
Equipment surfaces and fluid that’s heated can become very hot during operation. To avoid severe burns,
do not touch hot fluid or equipment. Wait until equipment/fluid has cooled completely.
Personal Protective Equipment
You must wear appropriate protective equipment when operating, servicing, or when in the operating
area of the equipment to help protect you from serious injury, including eye injury, inhalation of toxic
fumes, burns, and hearing loss. This equipment includes but is not limited to:
• Protective eyewear
• Clothing and respirator as recommended by the fluid and solvent manufacturer
•Gloves
• Hearing Protection
Warnings

Warnings
4311764D
CAUTION
• Water or material remaining in unit when temperatures are below freezing can damage
motor and/or delay pump startup. Do not allow unit to freeze.
• Before adding material or starting unit in cold weather, run warm water through pump.
To ensure water and material are completely drained out of unit:
1. Remove material line from sprayer.
2. Tip sprayer up as shown.
Before adding material to the hopper, install the burp guard. When only a small amount of
material remains in the hopper, the burp guard prevents material from shooting out when the
unit is turned off. This material could splash in the operator’s eyes or on skin, or into the air.

Pressure Relief Procedure
To reduce risk of injury, follow this procedure
whenever you see this symbol throughout this
manual, Also, perform this procedure whenever
you:
• Stop spraying
• Check or repair any part of this system
• Install or clean spray nozzle
1. Turn Power Switch OFF.
2. Trigger gun into material hopper.
3. Open gun air valve.
Grounding and Electrical Requirements
This sprayer must be grounded. Grounding reduces the
risk of electrical shock by providing an escape wire for
the electrical current. The sprayer cord includes 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.
Check with a qualified electrician or serviceman if
grounding instructions are not completely understood,
or if in doubt as to whether the product is properly
grounded. Do not modify plug provided; if it will not fit
the outlet, have proper outlet installed by a qualified
electrician.
120V AC Systems
• This equipment requires a
120V AC, 60 Hz, 15A circuit
with a grounding receptacle.
Do not use an adapter with
this product.
Extension Cords
• Use only an extension cord with an undamaged,
3-prong plug.
• For 25 to 50 ft (7.6 to 15.2 m) cords, use 3-wire, 14
AWG (1.5 mm2) minimum.
• For up to 100 ft. (30.48 m) cord, use 3-wire, 12 AWG
(2.5 mm2) minimum.
Auxiliary Air Compressor
Do not use an auxiliary air compressor with this spray
system.
Generator Requirements
3500 W (3.5 kW) minimum.
Hose Size and Length
The system comes with a hose set consisting of a 3/4 in.
ID x 25 ft (25 mm x 7.6 m) material hose and a 3/8 in-ID
air hose.
Do not use more than 25 ft (7.6 m) of material hose.

Mixing Material
10 311764D
Mixing Material
Dry Mix - 40 lb (18 kg) bag
1. Carefully mix texture material and water according
to manufacturer instructions on bag.
2. Agitate to mix, using a half-inch, variable speed drill
with mixing paddle, to a smooth, lump-free consis-
tency.
3. Allow ceiling texture to set for at least 15 minutes.
Then remix prior to use.
4. After texture material is thoroughly mixed, gently set
ball end of Material Thickness Gauge on surface of
mixture.
5. Observe the ball on the material. When the material
is thin enough to spray the ball will sink completely
into the mixture.
6. If the ball does not sink completely into the mixture
within 10 seconds, add more water, agitate and try
test again.
Premix
1. Slowly add approximately 2 to 4 qts (1.9 to 3.8 liters)
of water to a 5 gallon (18.9 liter) bucket of premix.
2. Agitate to mix, using a half-inch, variable speed drill
with a mixing paddle, to a smooth, lump-free consis-
tency.
3. After texture material is thoroughly mixed, gently set
ball end of Material Thickness Gauge on surface of
mixture.
4. Observe the ball in material. When the material is
thin enough to spray the ball will sink completely into
the mixture.
5. If the ball does not sink completely into the mixture
within 10 seconds, add more water, agitate and try
test again.
Correct material mixture is essential. The pump
will not operate if the mixture is too thick.
Mix the material in a separate container before
pouring it into hopper.
Use Material Thickness Gauge to determine mix-
ture is thin enough to spray.
*The Material Thickness Gauge will only deter-
mine if the material is thin enough to pass through
the pump. For some applications or for higher
speed spraying, your mixture may need to be thin-
ner.
For best results do not use partial bags of mate-
rial.
For an accurate test, be sure gauge is completely
dry and clean every time it is used.
