Prime the Pump
1. See Fig. 3. Remove the tip guard and spray tip
(31) from the gun (9). See the gun instruction
manual.
2. Close the air regulator (5) and bleed-type air
valves (B, 1).
3. Close the fluid drain valve (20).
4. Connect the main air supply hose (A) to the air
manifold (27).
5. Check that all fittings throughout the system are
tightened securely.
6. Open the bleed-type air valves (B, 1).
7. Hold a metal part of the gun (9) firmly to the side of
a grounded metal pail and hold the trigger open.
8. Slowly open the air regulator (5) until the pump
starts, about 40 psi (2.8 bar).
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.
Operation
Set the Air and Fluid Pressure
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 8.
1. Relieve the pressure. Install the tip guard and
spray tip (31) in the gun (9), as explained in the
gun manual.
2. Open the air regulator (5) slowly. Use the regulator
to control pump speed and fluid pressure. Always
use the lowest air pressure necessary to get the
desired results. Higher pressures cause premature
tip and pump wear.
NOTE: To open the air regulator, turn the T-handle in
(clockwise). To close the regulator, turn the handle
counterclockwise. To lock the regulator setting, tighten
the jam nut.
exceed the specified Maximum Incoming Air Pres-
sure to the pump (see the Technical Data, on
page 16).
3. 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.
