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 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

311772G 3

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 33 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

4311772G

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.

2. Tip sprayer up as shown.

Before adding material or starting unit in cold weather, run warm water through pump.

Before adding material to hopper, install 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.

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.

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
