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

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.

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 grounding 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.

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

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.

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.

• For 25 to 50 ft (7.6 to 15.2 m) cords, use 3-wire, 14 AWG (1.5 mm

• For up to 100 ft. (30.48 m) cord, use 3-wire, 12 AWG (2.5 mm

) 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.
