SETUP
To reduce the risk of serious bodily injury
caused by static sparking, fluid injection or
over–pressurization and rupture of the hose
or gun:
1. Ground the sprayer and all objects being
sprayed. Read FIRE OR EXPLOSION
HAZARD on page 3.
2. Do not operate the spray gun without a
tip guard in place.
3. Be sure all parts added to the sprayer
are rated for at least 2500 psi (175 bar)
Maximum Working Pressure.
WARNING
To avoid damaging the pressure control, fol-
low these precautions.
1. Always use flexible, grounded hose at
least 50 feet (15.2 m) long.
2. Never use a wire braid hose; it is too rig-
id to act as a pulsation dampener.
3. Never install any shutoff device between
the pressure control and the first 50 feet
(15 m) of hose. See Fig 1.
CAUTION
1. Connect a 50 foot spray hose and a gun to
the 1/4 npsm(m) fluid outlet nipple. For
more flexible gun movement, install a 3 foot
(0.9 m), 3/16 inch ID diameter hose between
the gun and main spray hose.
DO NOT use thread sealant on the hose and
gun connections. DO NOT install the spray tip
until the system is primed.
2. Fill the packing nut/wet–cup 1/3 full with
Throat Seal Liquid, supplied. Keep it filled to
help extend the life of the packings and the
pump.
3. Check the electrical service. It must be
120 VAC, 60 Hz, 15 Amp (minimum). The
electrical outlet must be properly grounded.
DO NOT remove the grounding prong of the
plug, and do not use an adapter.
Extension cords up to 100 feet (30 m) of 3
wire, 12 gauge (minimum) can be used.
Longer lengths may affect sprayer
performance. Use more spray hose to reach
the spray area, if needed.
4. Plug the power supply cord into an outlet
located at least 20 feet (6 m) from the spray
area. This reduces the chance of a spark ignit-
ing the spray vapors or dust particles.
5. Flush the pump to remove the lightweight
test oil which was left in it after factory testing.
See FLUSHING GUIDELINES on page 12.
6. Prepare the paint according to the instruc-
tions on the paint can. Strain the paint through
a fine nylon mesh bag to remove particles that
could clog the spray tip.
