WARNINGS

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 cementcious 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, page 3 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.

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.

• Do not operate with cover removed.

• Turn off sprayer. Follow Pressure Relief Procedure, page 3, and unplug unit, before removing any parts.

WARNINGS

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 3 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 of this instruction manual and in all other equipment manuals. Read fluid and solvent manufacturer’s warnings.

Sprayer Warnings

For sprayer operation and warning information refer to your sprayer or compressor operation manual.

Pressure Relief Procedure

To reduce the risk of serious bodily injury, includ-

ing electric shock and splashing fluid in eyes, follow this procedure whenever you stop spraying:

1. Shut OFF air source.

2. Disconnect power source.

3. Turn gun air valve ON.

Grounding

To reduce risk of electrical shock, proper

electrical grounding is essential. See your sprayer or compressor instruction manual and consult your local electrical codes for detailed grounding instructions.

remove plug and install hopper as described on page 5.

J Nozzle Different sizes available for use with different applications, See Nozzle Selection chart, page

K Hose Plug Must be installed when hopper is used. This feature is not utilized in this application. See

Graco RTX manual for installation and operating instructions for this feature.

Basic Operation

Hopper Installation

1. The Hose Plug must be securely fastened to bottom of gun when using the Hopper. Gun Plug must be removed from top of gun.

It is easier to remove plug if you first trigger gun.

2. Align notched opening in base of hopper to raised notch on hopper port of gun body.

4. Fasten clamp.

5. Connect air hose to gun.

6. Install spray nozzle, page

mix.

For overhead applications and high walls, position the hopper on the gun with the material fill opening facing toward the nozzle (front) of the gun. For all other applications, material fill opening should face the air valve (back) of the gun.

3. Push hopper down, over hopper port as far as it will go.

8. Open air valve.

Mixing Material

Correct material mixture is essential to achieve the desired finish.

Mix the material in a separate container before pouring it into hopper.

Dry Mix - 40 lb (18 kg) bag.

For best results do not use partial bags of material.

1. Slowly add one 40 lb. (18 kg) bag of texture material to 5-6 gallons (18.9-22.7 liters) of clean water as instructed on the bag instructions.

2. Agitate to mix, using a half-inch, variable speed drill with mixing paddle, to a smooth, lump-free consistency.

3. Allow ceiling texture to set for at least 15 minutes.

ti2497a

Then remix prior to use.

Premix

1. Slowly add approximately 2 to 4 qts (1.9 to

3.8 liters) of water to a 5 gallon (18.9 liter) bucket of premix.

2. Agitate to mix, using a half-inch, variable speed drill with a mixing pad-

Adjusting the System

Sufficient fluid output (volume and pressure) and good atomization is a balance of atomizing air, material thickness/material flow and nozzle selection. Achieving the correct balance for your application requires experimentation to achieve desired results. Keep in mind these important points when adjusting gun:

1 Select proper nozzle for your application. See

Nozzle Selection Chart. Remember, the larger the nozzle, the heavier the pattern.

2 Start with gun air flow

valve completely open. If needed, slowly close gun air flow until you get a good spray pattern.

ti2448a

3 Adjust air flow

adjustment nut and air valve to achieve uniform, round spray pattern. It may be necessary to change spray nozzles to achieve the desired spray pattern.

ti2475a

• When adjusting flow nut, release trigger, then adjust.

• If adjusting while triggered, needle will turn but provide no adjustment.

• If nut will not turn, check to see if it is either set to maximum adjustment or there is material on threads. Clean threads as needed.

• Test spray pattern on cardboard. Hold gun 18 to 24 in. (45.7 to 60.9 cm) from surface. Using a circular motion, overlap each stroke.

To Get Less Material

Try one or a combination of these methods:

• Open air valve.

• Turn gun flow adjustment nut to decrease flow, counter-clockwise.

• Use smaller nozzle.

To Get More Material

Try any one or a combination of these methods:

• Close air valve.

• Turn gun flow adjustment nut to increase flow, clockwise.

• Use thinner material mixture.

• Use a larger nozzle.

For Continuous Spraying

Use trigger lock to hold trigger open and reduce fatigue.

Check Material Consistency Periodically

Check and thin material as needed to maintain proper consistency. The material may thicken as it sits and slow down production. Agitate periodically.

Cleanup

When you have finished spraying

1. Shut off compressor. Disconnect air line from gun.

2. Drain remaining material into a bucket until most of the texture material is out of hopper.

3. Fill hopper with clean water. Remove nozzle from gun and allow water to flow through and out of gun.

4. Flush until gun is clean.

5. Remove hopper from gun and finish cleaning all components. A soft brush may be used to help loosen any dried on material from surface.

6. Connect air line to gun. Turn on compressor. Open gun air valve, forcing air through tip to clear out any remaining material.

7. Disconnect compressor.

Be sure to keep air passages in needle clean and free of material.

To improve working condition for future use, after cleaning, apply a few drops of light oil to:

• air hose quick disconnect

• material hose connections

• flow adjustment on gun
