Introduction
GM5000 BASIC COMPONENTS
NOTE: Refer to Fig.1.
Your new GM5000 Sprayer functions and operates dif fer-
ently than other airless paint sprayers. This section will
help
you become familiar with the sprayer before operat -
ing
it.
Pressure Control
The pressure control includes an ON/OFF switch for the
sprayer, the pressure adjusting knob, and a pressure-
sensing device. The pressure control engages and dis-
engages
the clutch to control pressure.
Engine
The engine is a 5 horsepower, four stroke, gasoline en-
gine. Its function is to drive the displacement pump to
supply paint. An adjustable throttle allows you to adjust
engine speed for large or small orifice spray tips. When
the
oil level is too low , the engine shuts of f automatically .
If
you try to start the engine without refilling the oil, a light
illuminates to alert you to the problem, and to protect the
engine from damage.
Clutch
The
clutch is engaged by the electric power generated by
the gasoline engine. The power is controlled by the pres -
sure
switch.
Drive Assembly
The permanently greased drive assembly transfers pow -
er
from the gasoline engine to the displacement pump.
Displacement Pump
The positive–displacement, volume-balanced pump pro -
vides
equal fluid delivery on both the up and down pump
strokes. The pump has a wetcup which, when filled with
Graco Throat Seal Liquid, 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 spray tip. The filter includes a reusable ele-
ment,
and a pressure drain valve for relieving fluid pres -
sure.
Hoses
The
grounded, nylon spray hoses have spring guards on
both ends. The 50 ft. (15.2 m) hose has a 1/4 in. ID. The
3 ft. (0.9 m), 3/16 in. ID whip hose provides more flexible
gun movement. The nylon hose material acts as a pulsa -
tion
dampener to absorb pressure fluctuations.
Spray Gun & RAC  IV DripLess  T ip Guard
Graco high pressure spray guns have a trigger safety
which prevents accidental triggering when the safety is
engaged.
See Fig. 1. The gun provided with the sprayer
also has a filter for final paint straining. The Reverse-A-
Clean
IV (RAC IV) SwitchT ip uses high pressure fluid
to remove clogs from the spray tip without removing the
spray tip from the gun. The Reverse-A-Clean IV Drip-
Less tip guard is a safety feature which helps reduce
the
risk of a fluid injection injury .
