Auxiliary Air Compressor
An external air compressor may be connected
(adapter included) to the auxiliary air compressor port
(L) to supplement or replace the internal air
compressor of the TexSpray. This may be useful when
Additional air is needed to break up hard-to-spray
materials
When the job site does not have the proper electric
service, but a gasoline-powered compressor is
available
WARNING
Overpressurizing the system may cause component rupture and result in serious injury.
To reduce the risk of overpressurizing the system, do
not use a compressor with an output pressure greater
than 100 psi (70 kPa, 7 bar), or with a delivery greater
than 6.8 scfm at 90 psi (0.19 m3/min. at 60.3 kPa, 6.3
bar).
Removing and Installing the Hopper
1. To remove the hopper (J), loosen the knob (P) until
about 1 in. of thread shows. Lift the hopper straight
up off the unit. See Fig. 8.
2. To install the hopper, position the hopper drain
over the pump inlets while tilting the hopper very
slightly forward. As you engage the inlets,
straighten the hopper and push down. Visually
inspect the pump inlets to be sure the hopper is
fully engaged. Tighten the knob (P). See Fig. 8.

Hose Size and Lengths
The system comes with a hose set consisting of a
1-in. ID x 25-ft (25 mm x 7.6 m) fluid hose and a
3/8-in. ID air hose. The 1-in. hose set includes an
adapter hose between the gun and main hose. See the
Parts List on page 25.
Use the shortest length possible when spraying.
Increasing hose length decreases sprayer
performance. Do not use more than 75 ft (23 m) of
fluid hose.

Preparation
Operation Characteristics
Always start the system with the compressor air
relieved.
How to relieve compressor pressure: Be sure
the gun air valve (423) and air restrictor valve (424)
are open. This relieves compressor air every time
you shut off the system. See Fig. 9.
Air bleeds from the gun nozzle when the gun air
valve (423) is open. See Fig. 9. You may close the
valve to stop the air, or you can leave it open at all
times except while priming the system. See Spray
Techniques on pages 12 and 13 for more gun
characteristics.
423
(shown open)
A compressor unloader valve (30) with two
pressure relief valves (30d) is located under the
compressor guard (16). Air escapes from the valve,
causing a popping sound, when air flow at the gun
is too restricted. The valve resets automatically
when the air flow is increased. See Fig. 10.
If air exhausts through the pump muffler or the
pump starts and then stops, see texture pump
instruction manual 309009.
Always have the fluid hose installed when there is
material in the hopper. If the hose is removed, the
hopper will drain out through the pump.
WARNING
The motor has a thermal overload switch that shuts
down the motor if it overheats.
To reduce the risk of serious bodily injury due to the
system restarting unexpectedly, always turn the
ON/OFF switch (D) OFF if the motor shuts down.
See Fig. 3 on page 5.

Preparation
Wetting the Hose Before Pumping Texture
Material
Wet the inside of the hose before each use to flush out
sediment and to prevent the texture material from
packing out the hose.
1. The hopper (J) capacity is 12 gallons (45 liters).
Pour a gallon (3.8 liters) of clean water into the
hopper. See Fig. 12 on page 10.
2. Close the gun air valve (423); the system primes
easier if no air is supplied to the gun. See Fig. 11.
3. Turn the ON/OFF switch (D) ON. Aim the gun into
the hopper (J), and trigger the gun to circulate the
water for a few minutes and to wet the inside of
the fluid hose. See Fig. 12.
4. Trigger the gun into a pail to lower the water to the
hopper strainer (L) level. See Fig. 12.
5. Turn the ON/OFF switch (D) OFF.
6. Open the gun air valve (423) to relieve the
compressor air. See Fig. 11.

Mixing the Material
CAUTION
This system is designed for use with only certain
types of material. Any other use could seriously
damage the unit.
Do not use any solvent-based materials. Use
only water-based materials.
Use only simulated acoustic and gypsum-based
wall texture materials in this system.
Do not spray cementious materials, which will
damage the pump.
Proper material mixture is essential. The pump will
not operate if the material is too thick.
NOTE: Mix the material in a separate container and
pour it into the hopper for best results.
Slowly add one bag of texture material to clean water
as instructed on the bag instructions. Agitate to a
smooth, lump-free consistency. Thin the material as
needed before pouring it into the hopper. Material
must be mixed thoroughly to a consistency that
immediately folds back in as you draw your finger
through the surface of the material. For the best
results, do not use partial bags of material.

aggregate material, disconnect the hose at the gun,
prime the pump and hose, and circulate material back
into the hopper for 10 seconds. Turn off the pump.
Install the gun and tip.
5. Turn the ON/OFF switch (D) ON. Trigger the gun
into a pail. When texture material appears at the
tip, move the gun to the hopper and circulate until
there is a solid stream of texture material.

Adjusting the System
1
Sufficient fluid output (volume and pressure) and good
atomization require testing to balance the compressor
air to the gun and pump and proper tip selection. Keep
in mind these important points when adjusting the gun:
Read all of pages 12 and 13 before spraying.
Start the sprayer with the gun air flow valve (424) at
its maximum setting (fully +). If needed, slowly
decrease the gun air flow until you get a good spray
pattern. Use the minimum amount of air at the
spray gun to achieve the proper spray pattern and
to minimize bounce back.
– Test the spray pattern on cardboard. Hold the
gun 18 to 30 in. (457 to 762 mm) from the
surface. Use this spraying distance for most
applications.
– Overlap each stroke 50% in a circular motion.
Select the proper tip for your application. See the
Tip Selection Chart at left. Consider the size of
aggregate in the material and the coarseness of the
spray pattern. Remember, the larger the tip, the
heavier the pattern.
All spraying adjustments are made at the gun.
Material pressure and flow rate adjustments are
made at the regulator.
The compressor provides air to the gun and the
pump; thus, the more air you supply to the gun, the
less that is available for the pump.
– Turning the air flow valve (424) toward (+)
increases air flow through the gun, which
decreases texture material flow through the
pump.
– Turning the air flow valve (424) toward (–)
decreases air flow through the gun, which
increases texture material flow through the
pump.
12 308718

Spray Techniques
To Get Less Material
Try any one or a combination of these methods:
Screw in the gun fluid regulator knob (418).
Use a smaller tip.
Reduce pump pressure. Use the regulator.
To Get More Material
Try any one or a combination of these methods:
Turn the air flow valve (424) to decrease (–).
Unscrew the fluid knob (418) to increase trigger
travel.
Note: Maximum trigger travel occurs when trigger
bail (401) can hold trigger in open position. Fig. 13.
Use a shorter hose.
Use a thinner material mixture.
Try a larger-orifice tip.
Increase pump pressure (use the regulator).
Preventing Material Surge
To prevent material surge at the beginning of a spray
pattern, slowly squeeze the trigger to the fully triggered
position while moving the gun quickly.
For Continuous Spraying
Use the trigger bail (401) to hold the trigger open to
reduce operator fatigue.
Check Material Consistency Periodically
Check and thin the material as needed to maintain the
proper consistency. The material may thicken as it sits
and slow down production or affect the spray pattern.

Shutdown and Cleanup
NOTE: Keep the pump and hose clean when switching
between texture, knockdown, and orange peel
applications. A dirty pump can release a piece of
texture into the finish.
CAUTION
To keep the unit in good operating condition, always
clean it thoroughly and prepare it properly for
storage, even if only for the night. Pay particular
attention to these areas:
Keep the pump wet during non-use to help
prevent contaminants from drying inside the
pump.
Clean the sponge filter at least daily. A dirty filter
allows contaminates into the compressor and
eventually into the pump, resulting in poor
performance and damage.
Removing the material hose will allow the pump
to drain too rapidly; the material hose must
remain connected to keep the pump wet.
Oil the gun daily. See Fig. 15.
Oil the pump air inlet. See Maintenance in
texture pump instruction manual 309009.
See Fig. 16 and Fig. 17
1. Be sure the compressor pressure is relieved by
opening gun air valve (423).
2. Close the gun air valve, and turn the ON/OFF
switch (D) ON.
3. Trigger the gun into a pail to lower the fluid to the
hopper strainer (L) level.
4. Half fill the hopper (J) with clean water. Clean the
inside of the hopper with a brush, if needed.
NOTE: The hopper can be removed for cleaning.
See page 7.
5. Trigger the gun into a pail until most of the texture
material is pumped out.
6. Fill the hopper with clean water.
7. Start the sprayer. Spray half the water into a pail.
Trigger the gun into the hopper to circulate the
remaining water for a few minutes.
8. Trigger the gun into the pail to empty the hopper
and the hose.
9. Turn the ON/OFF switch (D) OFF. Open the gun
air valve (423) to relieve compressor pressure.
