Fluid flow will be restricted if the material hose is kinked.

Page 9

Mixing Material

Correct material mixture is essential. The pump will not operate if the mixture is too thick.

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

Use Material Thickness Gauge to determine mixture is thin enough to spray.

*The Material Thickness Gauge will only determine if the material is thin enough to pass through the pump. For some applications or for higher speed spraying, your mixture may need to be thinner.

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.

4. After texture material is thoroughly mixed, gently set ball end of Material Thickness Gauge on surface of mixture.

For an accurate test, be sure gauge is completely dry and clean every time it is used.

5. Observe the ball on the material. When the material is thin enough to spray the ball will sink completely into the mixture.

ADD WATER

ti2498a

6. If the ball does not sink completely into the mixture within 10 seconds, add more water, agitate and try test again.

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.

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:

• Select proper nozzle for your application. See Nozzle Selection Chart. Remember, the larger the nozzle, the heavier the pattern.

• Start sprayer with gun air flow valve completely open. If needed, slowly close gun air flow until you get a good spray pattern. Use minimum amount of air at spray gun to achieve proper spray pattern and to minimize bounce back.

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.

Preventing Material Surge at Gun Trigger

Pressure will build up in the system when you stop triggering the gun. To prevent material surge at initial gun triggering:

• Point gun away from surface you are spraying when you first pull trigger.

• When you first start to spray, hold the gun away from the surface and gradually work your way closer to it.

• Keep gun moving.

+ Test spray pattern on cardboard. Hold gun 18 to 24 in. (45.7 to 60.9 cm) from surface. Use this spraying distance for most applications.

• Air and material flow adjustments are made at the gun on all units.

+ Opening air valve increases air flow through gun, which decreases texture material flow through pump.

+ Closing air valve decreases air flow through gun, which increases texture material flow through pump.

• Set air compression at a minimum of 25 psi. Additional air pressure may be needed for thicker materials or when product is applied to ceilings.

• After you begin spraying, trigger the gun as little as possible.

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.

Page 11

Shutdown and Cleanup

Keep pump and hose clean when switching between simulated acoustic, knockdown and orange peel applications. A dirty pump can release particles of texture into the finish.

CAUTION

• To increase pump life, turn power off when not spraying.

• Before removing material hose be sure pressure is relieved and material is not in hose.

• To keep unit in good operating condition, always clean it thoroughly and prepare it properly for storage.

5. Spray inside material hopper to circulate water through gun and hose. While circulating water, use gun to clean material hopper.

Texture Spraying (5 gallon Material Hopper)

When you have finished spraying:

1. Turn sprayer power switch (K) ON (air compressor can remain OFF).

ti9202a

2. Close gun air valve.

ti8527a

3. Trigger gun into bucket until most of texture mix is pumped out.

4. Fill material hopper with 2-4 gallons of clean water.

ti8371a

6. Spray water into a waste bucket to empty material hopper.

A soft brush can be used to loosen dried on material.

7. Turn sprayer power switch OFF.

8. Turn air compressor ON.

9. Open gun air valve to blow out any remaining texture residue. Flush with water.

CAUTION

If water freezes in unit, damage may occur. Store system where it will not freeze during cold weather.

10. Turn air compressor OFF.

Inspect slots under machine daily for texture material. If you find material flowing out of slots or see material inside unit, replace pump hose immediately.
