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)
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.
ATTACHING THE LID:
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.
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.
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.
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.
