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.
WARNING
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 all equipment in the work area. 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.
•
Keep a fire extinguisher in the work area.
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 kink or over bend hoses or 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).
•
Air hoses at the compressor end, can get very hot! Allow sprayer to cool down 15 minutes before
removing air hose.
•
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
WARNING
Electric Shock Hazard
To reduce the risk of electric shock:
•
Be sure sprayer is adequately grounded through electrical outlet, page 6.
•
Use only 3-wire, extension cords.
•
Make sure ground prongs are intact on sprayer and extension cords.
•
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 31 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
CAUTION
Water or material remaining in unit when temperatures are below freezing can damage
motor and/or delay pump startup. To insure water and material are completely drained out
of unit:
1. Remove material line from sprayer.
ti8713a
2. Tip sprayer up as shown.
Before adding material or starting unit in cold weather, run warm water through pump.
Install burp the guard (J) before adding material to the hopper. 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 into the operator’s eye or skin.

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.
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 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.
1. Turn Power Switch OFF.
120V AC Systems
•
ti8712a
2. Trigger gun into material hopper.
This equipment requires a 120V AC, 60 Hz, 15A
circuit with a grounding receptacle. Do not use an
adapter with this product.
Extension Cords
ti9084a
•
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.
3. Open gun air valve.
Auxiliary Air Compressor
