Adjust the Spray Pattern
1. Start the pump. Use the pump air regulator (G) to
adjust the pump speed and fluid pressure until the
spray is completely atomized. Use the lowest
pressure necessary to get the desired results.
Higher pressure may not improve the spray pattern
and will cause premature tip and pump wear.
NOTE: The fluid pressure regulator (201), which is
included on Models 232251, 232252, 232255, and
232256 only, allows more precise adjustment of the
fluid pressure at the gun.
WARNING
COMPONENT RUPTURE HAZARD
To reduce the risk of overpressurizing
your package, which could cause com-
ponent rupture and serious injury, never
exceed 100 psi (0.7 MPa, 7 bar) air input pressure
to the package. Never exceed 100 psi (0.7 MPa, 7
bar) air input pressure to the spray gun. Also refer
to the Technical Data on page 24 and to your sep-
arate component manuals.
2. When applying the fluid, keep the gun a consistent
distance, about 8 to 12 inches (200 to 300 mm)
from the surface of the object being sprayed.
Always hold the gun at a right angle from the
surface. Do not make an arc with the gun, as it
causes an uneven coat of fluid. Use a full-open,
full-close triggering action. Practice to find the best
length and speed of stroke.

Operation
3. To adjust the spray pattern, follow the instructions
in your gun manual, supplied.
4. With the pump and lines primed, and with ade-
quate air pressure and volume supplied, the pump
will start and stop as you open and close the gun.
Do not allow the pump to run dry. It will quickly
accelerate to a high speed, causing damage. If your
pump is running too fast, stop it immediately and
check the fluid supply. If the container is empty and
air has been pumped into the lines, refill the con-
tainer and prime the pump and the lines, or flush and
leave it filled with a compatible solvent. Eliminate all
air from the fluid system.
Shutdown and Care of the Pump
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 11.
For overnight shutdown, stop the pump at the bottom
of its stroke to prevent fluid from drying on the ex-
posed displacement rod and damaging the throat
packings. Relieve the pressure.
Always flush the pump before the fluid dries on the
displacement rod. See Flushing on page 17.
