1.Pour one (1) gallon (3.8 liters) of clean water into hopper.

2. Close gun air valve (23).

closed

3.Turn air inlet valve (E) open. Aim gun into hopper

(G) and trigger gun to circulate water for a few min- utes to wet inside of material hose.

4.Trigger gun into waste pail until hopper no longer contains water.

ti4290a

WASTE

5. Open gun air valve (23) to relieve compressor air.

Wetting System

1. Fill hopper (G) with prepared textured material.

ti3905a

NOTICE

Do not mix material in hopper. Mixing material in hopper can damage hopper, result in an inconsistent mix and packout can occur.

2.Install tip (see Nozzle Selection Chart, page 13).

3.Open gun air valve (23) to relieve air pressure.

NOTICE

Do not allow material to flow out of gun when air valve (23) is closed or material packout in needle can occur.

NOTE: If spraying a simulated acoustic and course aggregate material, disconnect hose at gun, prime pump and hose and circulate material back into hopper for 10 seconds. Turn off pump. Install gun and tip.

4.Inspect hose for kinks which could restrict fluid flow.

5.Trigger gun into a pail. When texture material appears at tip, move gun to hopper and circulate until material flows in a solid stream. See System Adjustment (page 14) for proper spray pattern and pump and gun adjustments.

ti4290a

WASTE

6.Adjust gun air pressure (U) and pump air pressure

(T) on sprayer to achieve desired result.

Mixing Material

NOTICE

Do not use any solvent-based materials. Use water-based materials only. Proper material mixture is essential. Pump will not operate if material is too thick.

NOTE: For best results, mix material in a separate container and pour it into hopper.

1.Slowly add one bag of texture to clean water as instructed on bag. For best results, do not use par- tial bags.

ti3906a

WATER

2. Agitate to a smooth, lump-free consistency.

ti3907a

Mixing Material

3.After texture is thoroughly mixed, gently set ball end of Material Thickness gauge on surface of mixture.

NOTE: For accurate test, be sure gauge is com- pletely dry and clean before each use.

4.Observe ball on material. When material is thin enough to spray, ball will sink completely into mix- ture.

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

NOTE: Thicker materials that do not pass Material Thickness Gauge test can still be used. Before spraying thicker materials, test pump performance first. If material is too thick, pump will perform poorly.

Operation Characteristics

Always start system with compressor air relieved. See

Pressure Relief Procedure, page 6.

???Always have material outlet plug installed in opening (K or L) not in use when material is in hopper. If plug is removed, hopper will drain out.

???Always have material hose installed in opening (K or L) when material is in hopper. If hose is removed, hopper will drain out through pump.

???Gun air pressure is regulated using air pressure control on sprayer (U) as well as gun air valve located on gun handle (23). Site gauge on sprayer allows duplication of air pressure setting. Gun air valve (23) allows for additional air pressure adjust- ment.

ti4005a

ti3787b

???Air pressure is controlled with pressure control knob

(J) and displayed on gauge.

System Adjustment

1. Open gun air valve (23).

2.Test spray pattern on cardboard. Hold gun 18 to 30 in. (45 to 75 cm) from surface. Use this spray dis- tance for most applications. Overlap each stroke 50% in a circular motion.

ti4004a

3.Adjust gun air valve (23) to achieve uniform, round spray pattern. It may be necessary to change spray nozzle to achieve desired spray pattern.

ti3999a

NOTE: Keep a small amount of air flowing through air line and gun tip to prevent material from backing up needle.

4.To select correct nozzle for your applications, con- sider size of aggregate in material and coarseness of spray pattern. Remember the larger the nozzle, the larger the spray pattern. See Nozzle Selection, page 13.

NOTE: More air produces a finer finish; less air pro- duces a coarse finish.

5.When adjusting flow adjustment nut (b), release trig- ger (C), then adjust.

ti4338a

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

If flow adjustment nut will not turn, check to see if it is:

???Set to maximum adjustment, or

???If there is material on threads. Clean threads as needed.

6.Check material consistency often. Material may thicken as it sits and slow down production or affect spray pattern. Thin with mater as needed to main- tain proper consistency.

Material Flow Adjustment

ti4339a

???For a lighter spray pattern, decrease material pres- sure at sprayer.

???For a heavier spray pattern, increase material pres- sure at sprayer.

Air Flow Adjustment

???Trigger gun.

???To decrease air flow, close air valve (23) clockwise.

???To increase air flow, open air valve (23) coun- ter-clockwise.

System Adjustment

NOTE: Keep a small amount of air flowing through air line and gun tip to prevent material from backing up needle.

Preventing Material Surge at

Gun Trigger

Pressure will build up in system when not triggering gun. To prevent material surge at beginning of spray pattern:

???Point gun away from surface to be sprayed when trigger is first pulled.

???Hold gun away from surface and gradually bring gun to surface.

???Trigger gun as little as possible.

For Continuous Spraying

ti4006a

???Engage trigger lock (D) to hold trigger open and reduce fatigue.

Shutdown and Cleanup

NOTICE

???Turn off sprayer if you are going to stop spraying for 5 minutes or longer.

???Before removing material hose, Relieve Pressure and make sure there is no material inside of hose.

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

???If water freezes in sprayer, damage may occur. During cold weather, store sprayer where it will not freeze.

After Spraying

1.Relieve Pressure, page 6.

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

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

Spray water into waste bucket to empty material hopper.

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

4. Follow Pressure Relief, page 6.
