Setup - Graco A Series Instructions-Parts List Manual

IMPORTANT: The model 231–347 sprayer is shipped
without a spray gun or hose. When a spray gun and
hose are referred to throughout this manual, the
instructions and figures depict a Graco
gun and hose may be different.
WARNING
If you supply 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 195 bar Working Pressure . This is to
reduce the risk of serious 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 a nylon spray hose at least 15 m
(50 ft) long.
2. Never use a wire braid hose as it is too rigid to
act as a pulsation dampener.
3. Never install any shutoff device between the
filter and the hose. See Fig. 3.
1. Plug the power cord (57) into the inlet receptacle
located below the motor. Tighten the screw (A) of
the cord clamp (65) securely. See Fig. 2.

Setup

2. Attach the fluid filter (85) to the sprayer.
3. Connect the hose and gun and screw it onto the
outlet nipple (28). Don't use thread sealant, and
don't install the spray tip yet!
4. Fill the wet–cup (102). Pry off the wet–cup seal.
Fill the cup 1/3 full with Graco Throat Seal Liquid
(TSL), supplied. Install the seal.
5. Check the electrical service. It must be 100 VAC,
50/60 Hz, 10 Amp (minimum) and must be
protected by a fuse or circuit breaker with a rating
of not more than 16 amps.
6. You may use a 3-wire, 2.0 mm
mum) extension cord up to 45 m long. Longer
lengths affect sprayer performance.
7. Plug in the sprayer. Be sure the ON/OFF switch
(52) is OFF. Plug the cord into a grounded outlet at
least 6 m away from the spray area.
FIRE AND EXPLOSION HAZARD
Proper electrical grounding is essential
to reduce the risk of fire or explosion
which can result in serious injury and
property damage. Also read FIRE OR
EXPLOSION HAZARD on page 2.
8. Flush the pump to remove the oil which was left in
to protect pump parts after factory testing. See
page 12.
9. Prepare the paint according to the manufacturer's
recommendations. Remove any paint skin. Stir the
paint to mix pigments. Strain the paint through a
fine nylon mesh bag to remove particles that could
clog the gun filter or spray tip. This is an important
step toward trouble–free paint spraying.
