IMPORTANT: Always use a minimum 12 gauge, three-wire
extension cord with a grounded plug. Never remove the
third prong or use an adapter.
Be sure to follow the Pressure Relief Procedure
when shutting the sprayer down for any purpose,
including servicing or adjusting any part of the
spray system, changing or cleaning spray nozzles,
or preparing for cleanup.
The air compressor motor is protected from
thermal overload by a thermal protector switch. If
the motor overheats, the thermal protector switch
will shut off the motor automatically. Make sure all
guards and shrouds are in place on the
compressor before pressing the reset switch after
a thermal overload. If this occurs, allow the motor
to cool for 10–15 minutes. Then, press the reset
switch located on the motor housing to restart the
motor.
Preparing to Spray
Use the following procedure to ush the sprayer with water
before spraying begins. This will remove any sediment that may
be in the system.
1. Fill the hopper 1/4 full with water.
2. Move the air adjustment valve on the spray gun
to the half-open (45º) position.
3. For the PowrTex 600DD only, turn the uid pressure
regulator fully counterclockwise to its minimum pressure
position.
4. Turn on the sprayer by
moving the ON/OFF switch to
the ON position.
5. For the PowrTex 600DD
only, turn the uid pressure
regulator clockwise until the
pressure gauge reads 30 PSI.
6. Trigger the spray gun into a
waste container. Continue
holding the trigger open until
the water has emptied from
the hopper.
7. Turn off the sprayer by moving the ON/OFF
switch to the OFF position.
The sprayer is designed for use with water-based texture materials
only. Prepare the material to be sprayed according to the
guidelines given by the material manufacturer as a reference point.
Do not use solvent-based materials in the sprayer.
Use of the wrong material can cause a fire and can
seriously damage the sprayer.
The proper mixing of the spray material is very important. Use
clean water only. Mix the material to a smooth consistency
before pouring it into the hopper. The sprayer will not operate if
the material is too thick.
A ow funnel is supplied with the sprayer to help
determine the proper thickness of the spray
material. The material should be mixed to a
smooth consistency that will ow evenly through
the ow funnel.
NOTE: Check the consistency of the material
often. After sitting in the hopper for awhile,
the material may thicken and need to be
thinned with additional water. Using the
provided hopper cover will reduce material
evaporation and help prevent change in material
consistency.
NOTE: When turning the unit on and off in rapid
succession, trigger the gun slightly to relieve
air pressure in the air hose for ease of restart.
Failure to do so may cause the compressor to
stall and trip the thermal protector switch.

Spray Gun Operation
The following section describes how to use the spray gun to
achieve professional results. Remember that practice and
experimentation with the controls, nozzle size, and spraying
technique is the best way to nd the desired spray pattern.
Using the Spray Gun Controls
The controls on the spray gun provide the opportunity to adjust
and ne tune the spray pattern for the different spray materials
that can be used. Make adjustments on the gun and then test
the spray pattern on a piece of cardboard or test surface.
Adjusting the Air Flow
Start spraying with the air adjustment valve turned fully clockwise
(vertical) in the open position. If necessary, turn the air adjustment
valve counterclockwise until a good spray pattern is achieved.
Turning the air adjustment valve counterclockwise will decrease
air ow through the gun and increase material output.
Turning the air adjustment valve clockwise will increase air ow
through the gun and decrease material output.

recommended not to
exceed 80 PSI.
piece of cardboard. Fine tune the spray pattern using
the uid adjustment knob and air adjustment valve on the
spray gun. Refer to the “Spray Gun Operation” section for
detailed information on gun adjustments.
Adjusting the Fluid Volume
Start spraying with the uid adjustment knob positioned to allow
minimum trigger pull. This will create minimum uid volume
owing to the texture nozzle when the trigger is pulled. If
necessary, turn off the sprayer, relieve system pressure, release
the lock nut, and turn the uid adjustment knob counterclockwise
to increase the uid volume owing to the texture nozzle.
Another way to adjust uid volume on the gun is to change the
size of the texture nozzle. A smaller nozzle will decrease the
uid volume. A larger nozzle will increase the uid volume.
Refer to the “Texture Nozzle Chart” in the Parts List section of
this manual for information on nozzle sizes and uses.

also can be adjusted using the uid pressure
regulator on the sprayer.
Please note that the double diaphragm pump
operates using air from the air compressor.
Any increase to the setting of the uid pressure
regulator to increase uid volume to the spray gun
will also decrease the air ow to the spray gun.
Spraying Technique
Hold the gun 18 to 30 inches from the surface. Squeeze the
trigger slowly and move the gun in a circular pattern. Consistent,
steady movement will prevent material buildup, runs, and sags.
NOTE: Pressure builds up in the system when the spray
gun is not triggered. Aim the gun away from the
spray surface when initially triggering the gun and
work toward the spray surface. This will prevent
material surge onto the spray surface. Keep the
gun moving and avoid repeated triggering of the
gun once spraying has begun.
Proper lapping (overlap of spray pattern) is essential to an even
nish. Lap each stroke. If you are spraying horizontally, aim
at the bottom edge of the preceding stroke, so as to lap the
previous pattern.
Maintain uniform spray stroke action. Spray alternately from left
to right and right to left. Begin movement of the gun before the
trigger is pulled.
Holding the gun closer to the surface deposits more material on
the surface and produces a narrower spray pattern. Holding the
gun farther from the surface produces a thinner coat and wider
spray pattern.
Converting the Spray Gun from NonBleeder to Bleeder
If preferred, the spray gun can be converted from a non-bleeder
to a bleeder setup. Non-bleeder setup means that when the
trigger is released, the air ow from the air nozzle stops. Bleeder
setup means that air ow is continuous from the air nozzle
whether the trigger is pulled or released.
NOTE: In bleeder setup, the removal of the bleed screw
from the air valve seal causes the air supply to
be on at all times when the air hose is attached
to the gun.
To convert a spray gun to bleeder setup:
1. Perform the “Pressure Relief Procedure” outlined in the
Operation section of this manual.
2. Remove the uid hose and air hose from the spray gun.
3. Turn the uid adjustment knob counterclockwise until it
threads off of the gun body. The adjustment spring inside
the uid adjustment knob will release once the knob is off
off the threads.
Installing a Texture Nozzle
Use the following procedure to install a different size texture
nozzle onto the spray gun.
1. Perform the “Pressure Relief Procedure” outlined in the
