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

f. However

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

f and relieve the pressure.

The direct–current (DC) motor is less sensitive to low voltage or voltage fluctuations than an alternating–cur rent (AC) motor af

fect the sprayer performance.

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

ally relieving fluid pressure.

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 (RAC IV) SwitchT clogs from the spray tip without removing it from the gun. The RAC IV DripLess tip guard is a safety feature which helps reduce the risk of a skin injection injury

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.

This procedure sets the sprayer to 3000 psi (210 bar) Maximum Working Pressure and sets the overpres surization switch (microswitch) to approximately 3600 psi (242 bar).

Perform this procedure whenever the pressure con trol is removed, installed or replaced, and whenever a new circuit board is installed.

An improper adjustment can cause the sprayer to over–pressurize and result in component rupture, fire or explosion. It can also prevent the sprayer from obtaining the maximum working pressure, resulting in poor sprayer performance.
