ASSEMBLY

ATTACHING THE AIR HOSE TO THE MACHINE AND GUN:

Your sprayer has 2 different air hose coupler fi ttings on it. Connect the air hose with the female coupler to the spray gun.

Then connect the male coupler on the air hose to the sprayer. Note, when using the DuoTex™ as a texture machine, you must connect the air hose to the coupler near the material hose coupler. (See Fig. 1)

When using the DuoTex™ as a stand-alone air compressor, connect the air hose to the coupler on the opposite side of the machine.

(See Fig. 1)

Mud Hose

Connector

Air Hose

Coupler - Spray

ATTACHING THE MATERIAL HOSE TO THE MACHINE AND GUN:

Once the air hose is attached, screw the material hose on to both the gun and sprayer. The material hose has a threaded coupler that is located directly below the hopper. (See Fig. 1) Hand tighten fi rmly, and do not over tighten.

Fig. 1

ATTACHING THE LID: Air Hose

Coupler - Tools

Attach the lid by placing it on the hopper and securing with the two rubber fasteners on the sides of the hopper. With the fasteners engaged, the lid seals tightly, helping to keep the drywall compound fresh while transporting the sprayer or storing over night, and between jobs. The lid should NEVER be fastened down while spraying. Doing so may cause a vacuum to form inside the tank, thus reducing the effi ciency of the sprayer.

PRODUCT OPERATION, INSTRUCTION INFORMATION

SPRAYER OPERATION

SPRAYER PRIMING:

There are 2 ways to prime the unit.

First method is the self-priming method. Simply turn up the mud fl ow and release a small amount of air out of the gun. The ball valve on the gun will need to be slightly open to allow air fl ow. This will overcome the system's "slow start" mechanism and allow the unit to self-prime. Aiming your gun back into the hopper is a good way to keep your work area clean during the priming process.

On/Off Switch

Second method is using the prime switch (See Fig. 2). This is a similar method to the fi rst, but allows the unit to prime without air going to the gun. Simply turn on the unit, make sure the mud fl ow and air fl ow are dialed slightly up. Using the ball valve at the gun, turn the air off at the gun. Press the prime button to allow the mud hose to prime. Hold the trigger on the gun closed and aim the gun into the hopper. Once the mud sprays into the hopper, the unit is primed. Release the prime button and begin using the sprayer.

Prime Switch

Fig. 2

NOTE: Prior to each new use (meaning the hopper is empty and refi lled with a new batch of texture), the material hose needs to be moistened. This procedure cleans any debris out of the tank, hose and gun and also keeps the initial run of material from hardening in the hose. See next page.

8 of 28


MARSHALLTOWN .com

WS1225

8-2017/Rev.B

To wet the hose:

1. Pour at least 1 gallon of clean water into the hopper.

2.

Follow the same instructions for priming the unit, as explained in the "Sprayer Priming" above.

3.

Once water is fl owing freely from the gun back into to the hopper, discard the water into an empty bucket.

4. Continue to spray into the discard bucket until all water is expelled from the hopper and hose.

MATERIAL PRESSURE ADJUSTMENTS:

An important feature of the DuoTex™ is the ability to adjust the material and air pressures separately. This allows for the tuning of very precise texture patterns. The material (mud) pressure regulator is the middle of the three regulators on the control panel (See FIG. 4).

This regulator has a lockable dial that needs to be pulled up to adjust. Once the dial is pulled up, turn clockwise to increase mud pressure or counter-clockwise to decrease mud pressure. Once the desired mud pressure is selected, pushing the dial back down will keep the unit running at a consistent pressure. 50 PSI is the maximum mud pressure.

SPRAY PRESSURE ADJUSTMENTS:

Mud Regulator

Fig. 4

This regulator increases/decreases the air pressure delivered to the gun when the unit is used as a texturing machine (See FIG. 5). This dial needs to be pulled up to be operated and pushed back down to lock it into place. After pulling up on the dial, turn clockwise to increase air pressure or counter clockwise to decrease pressure. Press the dial back down to lock in the pressure setting. The spray air pressure setting will have no effect on the material pressure setting.

Fig. 5

AIR PRESSURE ADJUSTMENTS (WHEN USED AS AN AIR COMPRESSOR):

The DuoTex™ is capable of being used as a stand-alone air compressor to power pneumatic job site tools like nailers and staplers.

To use as an air compressor, switch the Mode Selector dial from

Spray to Compressor (See FIG. 6). Connect air hose to the coupler used for compressor mode Use the dial on the air compressor regulator, named "Air Pressure" to adjust the pressure of the compressor. This dial needs to be pulled up to be operated and pushed back down to lock it into place. After pulling up on the dial, turn the dial clockwise to increase air pressure or counter-clockwise to

Fig. 6 decrease pressure. Press the dial back down to lock in the pressure setting.

MATERIAL NOZZLE INSTALLATION AND SELECTION

The DuoTex™ ships with six standard nozzle sizes: 3, 4, 6, 8, 10 and 12mm openings. The sprayer must be used with a spray nozzle at all times. To install a nozzle:

1.

Make sure machine is switched off or unplugged from the wall.

2. Open ball valve on gun (vertical position) and wait for all excess air to escape the system. Close ball valve

(horizontal position) once air stops coming out of the end of the gun.

3.

If there is material in the hose, press the gun trigger while the gun is directly over the hopper (with lid off).

This will allow any pressurized mud in the hose/gun to empty back into the hopper.

4.

Unscrew nozzle retaining collar and remove nozzle (if previously equipped).

5. Replace with new nozzle, and reconnect retaining collar. Pull the trigger on the gun while screwing on the

retaining collar to allow the nozzle to seat completely.

MATERIAL NOZZLE SIZE SELECTION:

A few general statements should be noted:

1.

Always read and follow the spray material manufacturer's mixing instructions. If not specifi ed in those instructions, the compound should be thoroughly mixed, free of

2.

lumps, and be the consistency of pancake batter.

Always set your pattern on scrap sheetrock before spraying your fi nished product.

Note the compound consistency, orifi ce size, air pressure at the compressor, relative ball valve position, and trigger setting for future reference.

Control Dial

Trigger Lock

3.

The more open the trigger, the more material that will be applied with a resulting coarser pattern.

4. The higher the air pressure, the fi ner the pattern; the lower the air pressure, the coarser the pattern.

5.

The higher the air fl ow, the fi ner the pattern; the lower the air fl ow, the coarser the pattern.

Ball Valve

6.

Larger orifi ce openings will produce a coarser pattern than a smaller opening.

7.

The position of the trigger controls the amount of material fl ow. As the trigger is pulled back, more material is allowed to feed through. Generally the distance between the air nozzle and the material nozzle should be slightly greater than the size of the selected orifi ce.

The gun on the DuoTex™ is intended to utilize a full trigger pull at all times. Adjusting the trigger fl ow control dial determines how far the air nozzle is pulled back. This allows for a more comfortable, full trigger pull. Use the trigger lock for reduced fatigue on larger projects.

SPRAYER CLEANING

The DuoTex™ has a sealable lid and is able to store unused material in-between uses for short periods of time. Materials that cure through exposure to the air (like drywall compound) can be stored in the hopper, but materials that chemically cure or contain portland cement (like stucco) can’t be stored in the hopper , as they will cure without exposure to air.

MATERIAL STORAGE:

If material is to be stored in the hopper, always clean overspray material off the outside of the machine, hose, and the external gun body. Leave the nozzle and retaining collar attached to gun while in storage.

DANGER!

Never clean the outside of the sprayer while it is plugged in

• Always make sure the seals on the lid are in good shape

• Always engage the 2 lid fasteners on the side of the hopper

• Leave all hoses attached to the machine and the gun attached to the hoses

CLEANING THE HOPPER:

Always spray remaining texture into a waste bucket. Fill hopper with water and spray through gun (with nozzle off) into a waste bucket. Continue to spray until water exiting the gun is clean.

The tank and body of the sprayer can be cleaned with hot, soapy water and a nylon brush or sponge. Do not use wire or metallic brushes, especially on the inside of the hopper, as metal will chip the inside of the hopper. This will cause the gun to clog and pieces of plastic to enter the spray pattern.

CLEANING THE GUN:

Clean the gun in clean water, making sure all material is removed from the inside chamber of the gun. To do so, remove the gun from both the mud hose and air hose. Unscrew the nozzle retaining collar from the gun and remove the air nozzle.

A nylon or soft brass cleaning brush can be used to remove material build-up from tight areas inside the gun, nozzle and collar. Always fl ush the gun and it’s components with clean water after all material has been removed. Dry completely.

MARSHALLTOWN offers a gun cleaning kit, part number 14285.

CLEANING THE MATERIAL HOSE:

The material hose can be cleaned with the supplied sponge cleaning ball.

After cleaning the hopper follow these steps:

1. Remove gun from both hoses.

2. Remove the material hose from the sprayer and insert the cleaning ball into the

material hose. Push the ball into the hose (at the material hose end), past the narrow part of the fi tting.

3. Reconnect the material hose.

4. Fill the hopper with at least 2 gallons of clean water.

5. Put the discharge end of the material hose in a waste bucket.

6. Start the sprayer and use the prime button to allow the ball to pass through the hose, to clean the inside walls of the hose.

7. Repeat if necessary, using clean water. All water passing through the hose should

Push cleaning ball past this point clean.

CLEANING THE SPRAYER:

Always make sure the sprayer is unplugged while cleaning its exterior body and frame. Final wipe should be with clean water and a soft cloth.

WARNING!

Warm soapy water and a nylon bristled scrub brush can be used to clean the exterior of the sprayer. Do not pressure wash or use a garden hose with a pressured nozzle. Doing so can force water into the electronics and controls of the sprayer, causing damage, malfunction and risk of electrical shock.

REMOVING THE HOPPER

The hopper can easily be removed for replacement, cleaning, or maintenance.

Unscrew the coupler that connects the material hose to the outlet of the hopper.

Simply remove the three screws on the inside of the hopper that connect it to its back rail. Note:

There is no need to remove the bucket rest from the hopper, simply remove the screw holding it in place.

Your hopper is now ready for removal. Replacement is opposite of removal.

Hopper coupler

Hopper screws

REPLACING PUMP HOSE

The DuoTex™ pump hose is easily replaceable in the fi eld.

1. Make sure machine is off and unplugged.

2. Remove the material hose from the sprayer.

3. Remove the hopper from the machine. See “Removing Hopper” above for instructions.

4. Remove wing nuts that hold on pump hose retention plate.

5. Slide bottom hose fi tting to the left and remove through the hole in the frame. Then

repeat with upper fi tting

6. Slide hose to the two open spots left by the removal of the retention plate,

then pull the fi ttings back through the front of the frame.

Note: Reassembly is opposite of removal.

BREAKING IN A NEW PUMP HOSE

Once hose is replaced you will need to break it in.

1. Ensure all holes are securely fastened.

2. Pour hot water into hopper.

3. Turn mud pressure to approximately 40 psi.

4. Turn machine on.

5. Engage prime switch, pumping water out of the hose and back into the hopper.

6. Run in this fashion for 1-2 minutes.

7. water.

USING THE UNIT AS AN AIR COMPRESSOR

Your DuoTex™ is capable of being used as a stand-alone air compressor to power pneumatic tools on the job site. It is capable of an air fl ow of 5.75 CFM @ 40 PSI, 3.00 CFM @ 90 PSI.

To operate as an air compressor:

1. Connect air hose powering pneumatic tool to air coupler for use as a compressor.

2. Turn selection dial on control panel to "compressor".

3. Adjust air pressure as desired using the dial labeled "Air Pressure". Pull up

on the regulator knob to adjust. Once correct pressure is selected, push

knob back down to lock it in place.

ELECTRICAL WIRING

Refer to the air compressor’s serial label for the unit’s voltage and amperage requirements. Use a dedicated circuit. For best performance and reliable starting, the air compressor must be plugged into a dedicated circuit, as close as possible to the fusebox or circuit breaker. The compressor will use the full capacity of a typical 15 amp household circuit. If any other electrical devices are drawing from the compressor’s circuit, the compressor may fail to start. Low voltage or an overloaded circuit can result in sluggish starting that causes the motor overload protection system or circuit breaker to trip, especially in cold conditions.

NOTE: A circuit breaker is recommended. If the air compressor is connected to a circuit protected by a fuse, use dual element time delay fuses (Buss Fusetron type “T” only).

EXTENSION CORDS & USING WITH A GENERATOR

Air Hose

Coupler - Tools

NOTE: Avoid use of extension cords.

For optimum performance, plug the compressor power cord directly into a grounded wall socket, or a generator with a minimum rating of 15 amps and 7500 watts. Do not use an extension cord unless absolutely necessary. Instead, use a longer air hose to reach the area where the air is needed. If use of an extension cord cannot be avoided, the cord should be no longer than 50 feet and be a minimum wire size of 12 gauge (AWG). Do not use a 16 or 14 gauge extension cord.

Use only a 3-wire extension cord that has a 3-blade grounding plug, and a 3-slot receptacle that will accept the plug on the product. Make sure your extension cord is in good condition. An undersized cord will cause a drop in line voltage, resulting in loss of power and overheating. The smaller the gauge number, the heavier the cord.
