Introduction
Pressure Control
The
pressure control includes an ON/OFF switch for
the sprayer
pressure–sensing device and a current–overload cir
, the pressure–adjusting control knob, a
cuit breaker with a manual–reset button. The pressure
control regulates the motor speed.
Motor
The DC motor has sealed bearings and replaceable
motor brushes. The motor operates whenever there is
a demand for fluid or additional fluid pressure. When
the pump is cycling, the motor sounds like the cranking
of an automobile starter
. When the pump is not cy
cling, the motor hums intermittently until the fluid pres
sure stabilizes, then the motor will shuts of

there is still power to the sprayer and the sprayer stays
pressurized and ready to use until you manually shut it

Drive Assembly
The
drive assembly, which is sealed, transfers power
from the DC motor to the displacement pump.
Displacement Pump
The
displacement pump provides equal fluid delivery
on both the up and the down pump stroke strokes. The
pump has a packing nut which, when filled with Graco
Throat Seal Liquid T(SL), helps prevent damage to the
throat packings and piston rod.
Fluid Filter
The
fluid filter strains the paint to help avoid clogs in
the hose and the spray tip. The filter includes a reus
able element and has a pressure drain valve for manu

Hoses

The grounded, nylon spray hoses have spring guards
on both ends. The 50 foot (15.2 meter) hose has a 1/4
inch ID. The 3 foot (0.9 meter), 3/16 inch ID hose pro
vides more flexible gun movement. The nylon hose
material acts as a pulsation dampener to absorb pres
sure fluctuations.
Spray Gun & RAC IV DripLess Tip Guard
The
spray gun has a trigger safety which prevents ac
cidental triggering when it is locked. The gun has a
filter for final paint–straining. The Reverse-A-Clean IV

FIRE OR EXPLOSION HAZARD
Static
electricity is created by the flow of fluid through the pump
and hose. If every part of the spray equipment is not properly
grounded, sparking may occur, and the system may become
hazardous. Sparking may also occur when plugging in or unplugging a power supply cord or using a gasoline engine.
Sparks can ignite fumes from solvents and the fluid being
sprayed, dust particles and other flammable substances,
whether you are spraying indoors or outdoors, and can cause
a fire or explosion and serious bodily injury and property
damage.
If you experience any static sparking or even a slight shock
while using this equipment, stop spraying immediately.
Check the entire system for proper grounding. Do not use the
system again until the problem has been identified and
corrected.
Grounding
To
reduce the risk of static sparking, ground the sprayer and
other
spray equipment used or located
