Additional helpful information.

CAUTION

Specifications

This equipment is not intended for use with flammable or combustible materials used in places such as cabinet shops or other “factory”, or fixed locations. If you intend to use this equipment in this type of application, you must comply with NFPA 33 and OSHA requirements for the use of flammable and combustible materials.

309477F 3

Warnings

The following are general related to the safe setup, grounding, use, maintenance, and repair of this equipment. Additional, more specific warnings may be found throughout the text of this manual, where applicable.

WARNING

FIRE AND EXPLOSION HAZARD

Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. To help prevent fire and explosion:

• Use equipment only in well ventilated area.

• Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and plastic drop cloths (potential static arc).

• When flammable liquid is used in or near the sprayer or for flushing or cleaning, keep sprayer at least 20 feet (6 m) away from explosive vapors.

• Do not clean with materials having flash points lower than 70°F (21°C). Use water-based materials or mineral spirits type material only. For complete information about your fluid, request the MSDS from the fluid distributor or retailer.

• Keep work area free of debris, including solvent, rags and gasoline.

• Do not plug or unplug power cords or turn lights on or off when flammable fumes are present.

• Ground equipment and conductive objects in work area. See Grounding instructions.

• If there is static sparking or you feel a shock, stop operation immediately. Do not use equipment until you identify and correct the problem.

• Keep a working fire extinguisher in the work area.

ELECTRIC SHOCK HAZARD

Improper grounding, setup, or usage of the system can cause electric shock.

• Turn off and disconnect power cord before servicing equipment.

• Use only grounded electrical outlets.

• Use only 3-wire extension cords.

• Ensure ground prongs are intact on sprayer and extension cords.

SKIN INJECTION HAZARD

High-pressure fluid from gun, hose leaks, or ruptured components will pierce skin. This may look like just a cut, but it is a serious injury that can result in amputation. Get immediate surgical treatment.

• Do not point gun at anyone or at any part of the body.

• Do not put your hand over the spray tip.

• Do not stop or deflect leaks with your hand, body, glove, or rag.

• Engage trigger lock when not spraying.

• Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning, checking, or servicing equipment.

4 309477F

WARNING

EQUIPMENT MISUSE HAZARD

Misuse can cause death or serious injury.

• Do not exceed the maximum working pressure or temperature rating of the lowest rated system component. See Technical Data in all equipment manuals.

• Use fluids and solvents that are compatible with equipment wetted parts. See Technical Data in all equipment manuals. Read fluid and solvent manufacturer’s warnings.

• Check equipment daily. Repair or replace worn or damaged parts immediately.

• Do not alter or modify equipment.

• Use equipment only for its intended purpose. Call your Graco distributor for information.

• Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.

• Do not kink or over bend hose or use hoses to pull equipment.

• Keep children and animals away from work area.

• Comply with all applicable safety regulations.

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.

PRESSURIZED ALUMINUM PARTS HAZARD

Do not use 1,1,1-trichloroethane, methylene chloride, other halogenated hydrocarbon solvents or fluids containing such solvents in pressurized aluminum equipment. Such use can cause serious chemical reaction and equipment rupture, and result in death, serious injury, and property damage.

TOXIC FLUID OR FUMES HAZARD

Toxic fluids or fumes can cause serious injury or death if splashed in the eyes or on skin, inhaled, or swallowed.

• Read MSDS’s to know the specific hazards of the fluids you are using.

• Store hazardous fluid in approved containers, and dispose of it according to applicable guidelines.

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 eye wear

• Clothing and respirator as recommended by the fluid and solvent manufacturer

•Gloves

• Hearing protection

309477F 5

Pressure Relief Procedure

To help prevent injuries, follow this procedure when you stop spraying and before you service or clean the sprayer, remove parts or repair leaks.

1. Turn OFF power switch.

ti2011

dx model

ti2018a

XR9 model

2. Unplug sprayer.

ti2021a1

3. Turn Prime/Spray valve to PRIME. Trigger gun to relieve pressure in hose.

to2012a

4. Engage trigger safety.

ti2048a

Leave Prime/Spray valve in PRIME position until you are ready to spray again.

If you suspect the spray tip or hose is completely clogged or that pressure has not been fully relieved after following the above steps, VERY SLOWLY loosen the tip guard retaining nut or hose end coupling to relieve pressure gradually. Then loosen it completely. Clear tip or hose obstruction.

6 309477F

Grounding and Electrical Requirements

This sprayer requires 220-240 VAC, 50/60 Hz, 10A circuit with a grounding receptacle. Do not use an outlet that is not grounded.

ti2021a

Do not use the sprayer if the electrical cord has a damaged ground prong. Only use an extension cord with an undamaged 3-prong plug.

ti2022a

Spray gun: ground through connection to a properly

grounded fluid hose and pump.

Fluid supply container: follow local code.

Solvent pails used when flushing: follow local code.

Use only conductive metal pails, placed on a grounded surface such as concrete. Do not place the pail on a nonconductive surface, such as paper or cardboard, which interrupts grounding continuity.

Grounding the metal pail: connect a ground wire to the pail by clamping one end to pail and other end to ground such as a water pipe.

To maintain grounding continuity when flushing or relieving pressure: hold metal part of the spray gun

firmly to the side of a grounded metal pail, then trigger the gun.

Thermal Overload

Motor has a thermal overload switch to shut itself down if overheated.

Only use an extension cord with an undamaged 3-prong plug. Recommended extension cords for use with this sprayer are:

• 15 m (49.2 ft) 1.0 mm

• 30 m (88.4 ft) 1.5 mm

• 50 m (164.0 ft) 2.5 mm

Smaller-gauge or longer extension cords may reduce sprayer performance.

WARNING

To reduce risk of injury from motor starting unexpectedly when it cools, always turn power switch OFF if motor shuts down.

309477F 7

WARNING

General Repair Information

• Do not operate the sprayer without the enclosure. Replace if damaged. Enclosures direct cooling air around the motor to prevent overheating. They also reduce the risk of burns, fire or explosion.

Page 4.

• Keep all screws, nuts, washers, gaskets, and electrical fittings removed during repair procedures. These parts are not normally provided with replacement assemblies.

•Test repair after problem is corrected.

• If sprayer does not operate properly, review repair procedure to verify you did it correctly. See Basic Troubleshooting, page 9 and Advanced Troubleshooting, page 11.

• Overspray may build up in the air passages. Remove any overspray and residue from the air passages and openings in the enclosures whenever you service the sprayer.

CAUTION

Do not run sprayer dry for more than 30 seconds. Doing so could damage pump packings.

Protect internal drive parts of this sprayer from water. Openings in enclosures allow for air cooling of mechanical parts and electronics inside. If water gets into these openings, the sprayer could malfunction or be permanently damaged.

Prevent pump corrosion and damage from freezing. Never leave water or water-based paint in sprayer when it is not in use in cold weather. Freezing fluids can seriously damage sprayer.

Store sprayer with mineral spirits/paint thinner or Graco Pump Armor to protect equipment during storage.
