The following Warnings are for the setup, use, grounding, maintenance and repair of this equipment. The exclamation point symbol alerts you to a general warning and hazard symbols refer to procedure-specific risks. Refer back to these

Warnings. Additional, product-specific warnings may be found throughout the body of this manual where applicable.

EQUIPMENT MISUSE HAZARD

Misuse can cause death or serious injury.

WARNINGS

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.

• Do not spray without tip guard and trigger guard installed.

• Engage trigger lock when not spraying.

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

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).

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

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

• Ground all equipment in the work area. See Ground-

ing instructions.

• Use only grounded hoses.

• Hold gun firmly to side of grounded pail when triggering into pail.

• 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.

• Do not operate the unit when fatigued or under the influence of drugs or alcohol.

• 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. For complete information about your material, request MSDS forms from distributor or retailer.

• Check equipment daily. Repair or replace worn or damaged parts immediately with genuine manufacturer’s replacement parts only.

• Do not alter or modify equipment.

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

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

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

• Keep children and animals away from work area.

• Comply with all applicable safety regulations.

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.

PERSONAL PROTECTIVE EQUIPMENT

You must wear appropriate protective equipment when operating, servicing, or in the operating area of the equipment to help protect you from serious injury. This equipment includes but is not limited to:

Pressure Relief Procedure

Follow this Pressure Relief Procedure whenever instructed to relieve pressure, stop spraying, check or service equipment, or install or clean spray tip.

1. Turn OFF power and turn sprayer pressure control to lowest pressure setting.

2. Hold gun against side of grounded metal flushing pail. Trigger gun into pail to relieve pressure.

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

Setup

WARNING

Make sure sprayer is turned off and unplugged from power source. Refer to your sprayer instruction manual for priming and spray instructions.

Connect Gun to Sprayer

1. Attach air hose.

NOTE: The first time you set up the gun for spraying you will have to cut the black air hose to length desired.

2. Attach fluid hose.

3. See Setup instructions in sprayer operation manual

(313316).

Operation

Note: The following instructions are for guns used with

Graco FinishPro Sprayers. See the sprayer instruction manual 313316. If you are using a different sprayer, see your equipment instruction manual.

3. Turn air adjustment valve off at gun.

4. Increase fluid pressure to eliminate tails.

5. Decrease fluid pressure until just before tails start to appear.

ti13279a ti12855a ti13321a ti13280a

6. Increase air pressure with air adjustment valve to eliminate tails.

7. Slide air on/off valve off

3. Hold gun perpendicular and approximately 12 in.

(304 mm) from surface. Move gun first, then pull gun trigger (D) to spray a test pattern.

4. Do not spray in an arc. This causes an uneven fluid coat. Spray in a path parallel to the surface, with a

50% overlap, to obtain an even fluid coat.
