Operation
12 3A1318B
9. When you have achieved the desired spray pattern,
release the gun trigger. The pump will continue to
cycle as long as air is supplied and the back pres-
sure regulator (12) is open.
10. One at a time, open any other guns in the system to
purge air from the lines.
NOTE: In a circulating system, the pump will continue to
cycle as long as air is supplied and the back pressure
regulator is open. In a direct supply system, the pump
starts when the gun is opened, and stops when the gun
is closed.
Elevator Operation
1. To raise the elevator (150), connect the quick cou-
pler (124) on the end of the coiled hose (105) to the
male fitting (J) on the air control valve (K). Pull up
the air control valve button to raise the elevator to its
full height.
2. Position a full drum under the drum cover (114).
3. To lower the elevator (150), press down the air con-
trol valve (K) button. Lower the elevator until the
cover (114) rests properly on the lip of the drum.
Disconnect the quick coupler (124) from the male fit-
ting (J).
4. Refer to manual 306287 for further elevator operat-
ing instructions.
Agitator Operation
1. Close the agitator’s needle valve (L).
2. Connect the quick coupler (124) on the end of the
coiled hose (105) to the male fitting (M) on the agita-
tor (102).
3. Slowly open the needle valve (L) to start the agitator
(102). Use the valve to adjust the speed. Do not
operate the agitator too fast. If the fluid foams or a
vortex forms on the fluid surface, reduce the speed
of the agitator.
4. Refer to manual 308609 for further agitator operat-
ing instructions.
Shutdown
1. Lower the elevator (150).
2. Shut off the agitator (102).
3. Follow Pressure Relief Procedure , page 11.
NOTE: When changing fluid containers with the hose
and gun already primed, open the drain valve (D) to help
prime the pump and vent air before it enters the hose.
Close the drain valve when all air is eliminated.
NOTICE
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. Elimi-
nate all air from the fluid system.
