WARNING
If you are supplying your own hoses and spray gun,
be sure the hoses are electrically conductive, that
the gun has a tip guard, and that each part is rated
for at least 2750 psi (190 bar) Maximum Working
Pressure . This is to reduce the risk of serious bodily
injury caused by static sparking, fluid injection or
over-pressurization and rupture of the hose or gun.
CAUTION
To avoid damaging the pressure control, which
may result in poor equipment performance and
component damage, follow these precautions.
1. Always use nylon spray hose at least 50 ft.
(15.2 m) long.
2. Never use a wire braid hose; it is too rigid to act
as a pulsation dampener.
3. Never install any shutoff device between the fil-
ter and the main hose. See Fig 1.
4. Always use the main filter outlet for one gun op-
eration. Never plug this outlet.
1. Connect the hose and gun (See Fig 1)
a. Remove the plastic cap plug from the filter outlet
nipple and screw a minimum 50 ft. (15.2 m) main
fluid hose onto the nipple.
b. For more flexible gun movement, connect a 3/16"
ID, 3 ft (0.9 m) hose between the main fluid hose
and the gun inlet adapter.
c. DO NOT use thread sealant, and DO NOT install
the spray tip yet!
2. Fill the packing nut/wet–cup 1/3 full with Graco
Throat Seal Liquid (TSL), supplied. See Fig 1.
SETUP
3. Check the electrical service
a. Be sure the electrical service is 120 V, 60 HzAC,
15 Amp (minimum), and that the outlet you use
is properly grounded.
b. DO NOT remove the grounding prong of the plug,
and do not use an adapter.
c. Use a grounded extension cord which has 3 wires
having a 12 gauge size, and a maximum length
of 100 ft (30 m). Longer lengths or smaller gauges
may affect sprayer performance.
4. Be sure your system is properly grounded before
operating it. Read and follow the warning section,
FIRE OR EXPLOSION HAZARD, on page 3.
5. Plug in the sprayer
a. Be sure the ON/OFF switch is OFF. See Fig 1.
b. Plug the power supply cord into a grounded elec-
trical outlet that is at least 20 ft (6 m) aways from
the spray area to reduce the chance of a spark ig-
niting the spray vapors.
c. Do not remove the third prong of the power sup-
ply cord plug, which is the grounding prong, and
do not use an adapter.
6. Flush the pump to remove the lightweight oil which
was left in the pump to protect it from rust.
a. Before using water-base paint, flush with mineral
spirits, followed by a soapy water flush, and then
flush with clean water.
b. Before using oil-base paint, flush with mineral
spirits, only.
c. See FLUSHING GUIDELINES, on page 12, for
the flushing procedure.
7. Prepare the paint according to the manufacturer 's
recommendations.
a. Remove any skin that may have formed.
b. Stir the paint to mix pigments.
c. Strain the paint through a fine nylon mesh bag
(available at most paint dealers) to remove par-
ticles that could clog the filter or spray tip. This is
probably the most important step toward trouble-
free spraying.
