•Do not expose to rain. Store indoors.
•Wait five minutes after disconnecting power cord before servicing.
PRESSURIZED ALUMINUM PARTS HAZARD
Use of fluids that are incompatible with aluminum in pressurized equipment can
cause serious chemical reaction and equipment rupture. Failure to follow this
warning can result in death, serious injury, or property damage.
•Do not use 1,1,1-trichloroethane, methylene chloride, other halogenated
hydrocarbon solvents or fluids containing such solvents.
•Do not use chlorine bleach.
•Many other fluids may contain chemicals that can react with aluminum. Contact
your material supplier for compatibility.

Warnings
63A4442B
MOVING PARTS HAZARD
Moving parts can pinch, cut, or amputate fingers and other body parts.
•Keep clear of moving parts.
•Do not operate equipment with protective guards or covers removed.
•Pressurized equipment can start without warning. Before checking, moving, or
servicing equipment, follow the Pressure Relief Procedure and disconnect all
power sources.
PLASTIC PARTS CLEANING SOLVENT HAZARD
Many solvents can degrade plastic parts and cause them to fail, which could cause
serious injury or property damage.
•Use only compatible water-based solvents to clean plastic structural or
pressure-containing parts.
•See Technical Specifications in this and all other equipment instruction
manuals. Read fluid and solvent manufacturer’s Safety Data Sheet (SDS) and
recommendations.

Preparation
Grounding
This sprayer includes a ground wire with an
appropriate ground contact. The plug must
be plugged into an outlet that is properly
installed and grounded in accordance with all
local codes and ordinances.
Do not modify the plug provided; if it does not
fit the outlet, have the proper outlet installed
by a qualified electrician.
Power Switch
Select 10A or 16A depending on your circuit
rating.
230V units require 220-240 VAC, 50/60 Hz,
10 – 16A, 1 phase
Extension Cords
Use an extension cord with an undamaged
ground contact. If an extension cord is
necessary, use a 3-wire, 12 AWG (2.5 mm2)
minimum.
NOTE: Lighter gauge or longer extension
cords may reduce sprayer performance.
Generator Requirements
5000 W (5 kW) minimum.
ProGuard
The ProGuard protects the sprayer against
high and low voltage spikes. If the sprayer is
plugged into a power source that goes too
low or too high the sprayer stops operating.
VIBRA-FLO Shaker
Thehoppershaker vibratesthehopperwhich
assists in moving the material down to the
pump inlet at the bottom of the hopper.
Bag Roller (Optional)
Bags of material can be difficult to empty. A
bag roller provides a quick and easy way to
empty material bags directly into the hopper.
Mixing Material
NOTE: Correct material mixture is essential.
The pump and spray gun will not operate if
the mixture is too thick. Use water-based
materials only.
1. Mix the material and water in a
separate container.
Dry Mix
Carefully mix texture material and water
according to manufacturer instructions
on bag.
The equipment must be grounded to
reduce the risk of static sparking and
electric shock. An electric or static spark
can cause fumes to ignite or explode. An
improper ground can cause electric shock.
Agoodground provides an escape wire for
the electric current.

Pressure Relief Procedure
Follow the Pressure Relief
Procedure whenever you see this
symbol.
1. Turn ON/OFF switch to the OFF
position. Wait 7 seconds for power to
dissipate.
2. Engage trigger lock. Always engage the
trigger lock when sprayer is stopped to
prevent the gun from being triggered
accidentally by hand or if dropped or
bumped.
3. Turn pressure control to lowest setting.
Disengage the trigger lock.
4. Trigger the gun to relieve pressure.
5. Engage trigger lock.
6. Putdrain tube inapail.Turn primevalve
down. Leave prime valve in the down
(drain) position until you are ready to
spray again.
7. If you suspect the spray tip or hose is
clogged or that pressure has not been
fully relieved:
a. VERY SLOWLY loosen the tip
guard retaining nut or the hose end
coupling to relieve pressure
gradually.
b. Loosen the nut or coupling
completely.
c. Clear hose or tip obstruction.
This equipment stays pressurized until
pressure is manually relieved. To help
prevent serious injury from pressurized
fluid, such as skin injection, splashed fluid
and moving parts, follow the Pressure
Relief Procedure whenever sprayer is
stopped and before sprayer is cleaned or
checked, and before equipment is
serviced.

damage when transporting sprayer.
NOTE: New sprayers are shipped with
storage fluid that must be flushed out prior
to using the sprayer.
Check flushing fluid for compatibility with
material that is to be sprayed. A secondary
flush with a compatible fluid may be
necessary. Use water for water-based
materials.

Clear Tip Clog
To avoid tip clogs:
•When the gun is not in use for extended
periods of time, keep the tip “wet” and
perform Pressure Relief Procedure,
page 10.
•Keep tip clean and free of material.
•Engage trigger completely when
spraying. Partial trigger engagement
increases the chances of tip clogs.
1. Engage trigger lock. Rotate spray tip to
unclog position. Disengage trigger lock.
Trigger gun at waste area to clear clog.
UNCLOG
NOTE: If spray tip is difficult to rotate when
turning to the unclog position perform,
Pressure Relief Procedure, page 10, then
turn Prime/Spray valve to spray position and
repeat step 1.
2. Engage trigger lock. Rotate spray tip
back to spray position. Disengage
trigger lock and continue spraying.
SPRAY
Useful Tip
When spraying, if the gun is not used for a
significant period of time be sure to clean the
sprayer, or keep the gun “wet” by placing in
water or wrapping with a wet cloth. This
reduces the potential of the material drying in
the gun causing pack-out of the gun.

Error Code Definition
Multiple incoming voltage surges detected - unplug sprayer

electronics.
Typicalcauseofthiserrorispluggingintoacircuitthatishigherthan
the rated voltage of the sprayer. Find a circuit that supplies the
correct voltage.
Incoming voltage too low for sprayer operation - unplug
sprayer and locate good voltage supply to prevent damage to
electronics.
Typical cause of this error is other equipment on the same circuit or
generator frequently turning on/off under load. Find a circuit that is
dedicated to the sprayer.
Sprayer plugged into wrong voltage - unplug sprayer and
locate correct voltage supply.
Typical cause of this error is a GFCI box that is wired for the wrong
voltage (240V vs. 120V). No damage has occurred to the sprayer.
Find a circuit with the correct voltage and the sprayer will run
correctly.
