Pressure Relief Procedure
Follow the Pressure Relief
Procedure whenever you see this
symbol.
This equipment stays pressurized until
pressure is manually relieved. To help
prevent serious injury from pressurized
fluid or splashed fluid follow the Pressure
Relief Procedure whenever sprayer is
stopped and before sprayer is cleaned or
checked, and before equipment is
serviced.
1. Turn ON/OFF switch to the OFF
position. Wait 7 seconds for power to
dissipate.
2. Unplug sprayer.
3. Turn fluid regulator all the way down.
4. Aim gun into hopper or waste bucket and
trigger the gun until all air and material
pressure is relieved.
Grounding
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.
A good ground provides an escape wire for
the electric current.
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
A selector switch on the sprayer allows you
to operate the sprayer on either a 10A/240V
15A120V or 16A/240V or 20A120V circuit.
120V Sprayers
Select 15A or 20A depending on your circuit
rating.
240V Sprayers
Select 10A or 16A depending on your circuit
rating.
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 mm
minimum.
NOTE: Lighter gauge or longer extension
cords may reduce sprayer performance.

Preparation
Hose Size and Length
The system comes with a 25 ft (7.6m) long
hose set consisting of a material hose 1 in. or
1.25 in. I.D. and a 3/8 in. I.D. air hose.
SoftStart/Smart Start™ System
“Soft Start” vs. “Smart Start”
•
“Smart” refers to the function where the
motor starts and stops when the trigger
is pulled and released. This keeps the
sprayer at full operating pressure and
allows the sprayer to spray immediately
when the gun is triggered.
• “Soft” refers to the function where the
sprayer slowly starts the pump. This
prevents a large “splotch” of material
from being discharged from the gun
when trigger is pulled after the sprayer
has sat idle for a period of time.
Soft Start
The Soft Start System is controlled by motor
power and an air cylinder. When pressurized,
the air cylinder pushes the rollers into the
peristaltic pump pushing material through the
pump. When the motor shuts off, a solenoid
valve relieves the pressure in the air cylinder
causing the rollers to disengage from the
peristaltic pump. When the motor starts again
there is a time delay while the air cylinders
charge and move the rollers into the pump
this is the “Soft Start”.
Smart Start
The Smart Start System is controlled by
compressed air in the tanks and lines. When
gun is triggered, air flows through the lines
and opens a flow switch. There is also
another pressure switch that senses when
the compressed air system is at operating
pressure. This second pressure switch
allows the sprayer to start immediately when
the sprayer is turned ON charging the
compressed air system to full pressure. This
method keeps the compressed air system at
operating pressure if there is a small air leak
in the system.

4. Plug power cord into a properly
grounded outlet.
5. Make sure burp guard is installed.
Before adding material to the hopper,
install the burp guard. When only a small
amount of material remains in the hopper,
the burp guard prevents material from
shooting out when the unit is turned off.
This material could splash in the operator’s
eyes or on skin, or into the air.

2. Hand tighten fitting.
Remove Hopper
Material hopper can be removed for easy
cleaning.
1. Loosen outlet fitting. Fittings are handtightened and should not require tools
to loosen.
Mixing Material
NOTE: Correct material mixture is essential.
The pump will not operate if the mixture is too
thick. Use water-based materials only.
• Mix the material in a separate container
before pouring it into hopper.
• Use Material Thickness Gauge to
determine if mixture is thin enough to
spray.
• The Material Thickness Gauge will only
determine if the material is thin enough
to pass through the pump. For some
applications or for higher speed
spraying, your mixture may need to be
thinner.
• If thicker materials are desired, test
pumping performance first. Then spray a
test pattern.
• For best results, do not use partial bags
of material.
1. Mix the material and water in a
separate container.
Dry Mix - 40 lb (18 kg) bag
