WARNING

WARNINGWARNINGWARNING

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 Grounding 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.

EQUIPMENT MISUSE HAZARD

Misuse can cause death or serious injury.

• 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.

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. Lock trigger. Turn OFF power and turn pressure control to lowest pressure setting.

2. Unlock trigger. Hold gun against side of 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.

Gun Trigger Lock

To prevent injury when the gun is not in use, always lock the trigger if unit is being shut down or left unattended.

Trigger Locked

(no spray)

Trigger Unlocked

(spray)

2. For Air-Assisted spraying, black, coiled, air supply hose (a) to gun air inlet fitting (17). NOTE: The first time you set up the gun for spraying you will have to cut the black air hose to length desired.

3. Attach blue fluid supply hose (b) to gun fluid inlet fitting(25).

4. Attach other end of air and fluid supply hoses to sprayer. Use two wrenches to tighten all connections securely (see sprayer setup instructions in sprayer operation manual 311905.)

Installing Tip (33) and Guard (6) on Gun

1. If equipment has recently been operated, relieve pressure.

2. Insert seat housing (35) into guard (6).

3. Insert SwitchTip (33).

4. Insert seal (33b) over seat (35a) and insert in seat housing (25). Use black seal for water-based materials and orange for solvent and oil-based materials.

5. Install guard (6) over end of gun. Hand tighten.

If you notice fluid leaking from front of gun, replace the seat (33a) and/or retighten the guard nut.

Setup

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

Operation

Note: The following instructions are for guns used with

Graco’s FinishPro Sprayers. See the sprayer instruction manual 311905. If you are using a different sprayer, see your equipment instruction manual.

If you are using a FinishPro

regulation is only provided at the gun. The FinishPro Model Sprayers provide additional air regulation at the

sprayer.

Connect Gun to Sprayer

1. Attach air inlet fitting (17) and fluid inlet fitting (25) to gun.

1. Unlock trigger (1a).

ti9444a

2. Be sure the arrow shaped tip (33) faces forward (spray).

3. Hold gun perpendicular and approximately 12-inches (304 mm) from surface. Move gun first, then pull gun trigger (3) to spray a test pattern.

4. Always hold gun at a right angle from the surface. Do not make an arc with the gun. This causes an uneven coat of fluid. To obtain an even finish, use smooth, even strokes across the object being sprayed with a 50% overlap.

Warnings

Clearing a Clog

1. Relieve pressure. Lock trigger (1a).

2. Rotate tip (33) 180°. Unlock trigger (1a). Trigger gun into pail or onto ground to remove clog.

3. Lock trigger (1a). Rotate tip (33) 180° back to spray position.

Spraying

Refer to your Sprayer Instruction manual. The following instructions are for guns used with Graco’s FinishPro

Sprayers.

Air-Assisted Spraying

1. Set sprayer function selection switch to AIRLESS spraying.

2. Open gun air pressure regulator all the way.

3. Prime pump following priming instructions provided in sprayer operation manual 311905.

4. Turn sprayer fluid pressure control to highest setting.

5. Unlock trigger (1a). While triggering gun, turn down sprayer fluid pressure until you notice tails forming in spray pattern.

6. Stop triggering gun.

7. Set sprayer toggle switch to AA (Air Assisted) spraying.

8. Trigger gun. While spraying increase gun air pressure regulator until tails disappear.

9. Use gun air regulator to fine tune spray pattern.

Airless Spraying

1. Set sprayer function selection switch to AIRLESS spraying.

2. Prime pump following priming instructions provided in sprayer operation manual 311905.

3. Start with sprayer pressure turned to lowest setting.

4. Spray a test pattern. Gradually increase sprayer pressure until you achieve a consistent spray pattern, without heavy edges. Use a smaller tip if pressure adjustment alone does not eliminate edges.

Note: If you are getting an irregular spray pattern, clean air holes with solvent and a soft brush or toothpick. Do not use metal tools to clean the air cap holes as this may scratch them. Scratches can distort the spray pattern.

Maintenance

Before performing any maintenance on gun, read all warnings on front cover of this manual and relieve pressure, page 4.

Daily Maintenance

Flush gun after each work shift and store in a dry location.

Do not immerse the gun or any parts in water or cleaning solvents.

• Do not point gun up while cleaning it.

• Do not wipe gun with cloth soaked in solvent; wring out excess.

• Solvent left in gun air passages could result in a poor quality paint finish. Do not use any cleaning method that may allow solvent into gun air passages.

Flushing and Cleaning

• Flush gun before changing colors, before storing and before

repairing gun.

• Flush at lowest possible pressure. Check connectors for

leaks and tighten as necessary.

• Flush with fluid that is compatible with fluid being dispensed

and equipment’s wetted parts.

1. Relieve pressure, page 4. Unplug sprayer from outlet.

2. Remove tip (33) and guard (6).

3. Disconnect black air supply hose from gun.

4. Remove sprayer siphon tube set from paint and place in flushing fluid. See Cleanup instructions in sprayer operation manual 311905.

5. Plug sprayer in outlet. Set sprayer function selection switch to AIRLESS.

6. Increase pressure slowly. Point gun down into a grounded metal container. Pull gun trigger and flush gun with solvent until all traces of fluid are removed from gun passages.

7. Turn sprayer function selection switch to OFF.

8. Relieve pressure, page 4.

9. Disconnect fluid supply hose from gun.

10. If it is necessary to remove diffuser (5) to clean, trigger gun while you remove the diffuser with the gun tool (30).

11. Dip the soft end of a soft-bristle brush into a compatible solvent. Do not continuously soak the brush’s bristles with solvent and do not use a wire brush.

12. With gun pointed down, clean front of the gun with the soft-bristle brush and solvent.

13. Scrub the tip (33) and guard (6) with soft-bristle brush. To clean out air cap holes, use a soft tool such as a toothpick, to avoid damaging critical surfaces. Blow air through the spray tip to ensure the orifice is clean.
