Prime the Pump (continued)
7. Hold a metal part of the gun (106) firmly to the side
of a grounded metal pail and hold the trigger open.
8. Open the bleed-type air valves (B, E) and the gun
air filter/regulator (J). Slowly open the pump air
regulator (G) until the pump starts.
9. Cycle the pump slowly until all air is pushed out
and the pump and hoses are fully primed.
10. Release the gun trigger and lock the trigger safety.
The pump should stall against pressure.
11. If the pump fails to prime properly, open the drain
valve (F). Use the drain valve as a priming valve
until the fluid flows from the valve. Close the valve.
NOTE: When changing fluid containers with the hose
and gun already primed, open the drain valve (F) to
help prime the pump and vent air before it enters the
hose. Close the drain valve when all air is eliminated.
Install the Spray Tip
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 10.
Relieve the pressure. Install the spray tip and tip guard
as explained in your separate gun manual, supplied.
The fluid output and pattern width depend on the size
of the spray tip, the fluid viscosity, and the fluid pres-
sure. Use the Spray Tip Selection Chart in your gun
instruction manual as a guide for selecting an
appropriate spray tip for your application.
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.

Operation
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 18 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.
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 10.
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 13.
