6.
Open bleed type master air valve (B) to begin
dispensing.

7.
When the material level in the hopper is within a
few inches of the material inlet at the bottom:
a.
Scrape the material down the sides of the
hopper.
b.
Fill the hopper with water or solvent as the
material runs out and continue dispensing.
8.
Keep the hopper filled with material flushing
agent while dispensing.

Note
NOTE:
NOTE:
NOTE: Be prepared to decrease the air
pressure when the material exiting the
hose changes to water or solvent. Water
and solvent pump more easily so pump
speed will increase.
9.
When water or solvent begins to exit the
applicator outlet, close the pilot ball valve (G)
located on base of applicator to stop dispensing.
10. Place applicator in the system hopper with the
outlet pointing down to enable fluid circulation.
Note
NOTE:
NOTE:
NOTE: If flushing with solvent, do not
submerge the applicator in the solvent.
11. Circulate clean water or solvent:
a.
Fill the system hopper with clean water or
solvent.

b.
Use a scrub brush to scrub the walls of the
hopper.
c.
Open the pilot ball valve (G) on applicator to
begin circulating water or solvent.
d.
Run the pump at 60-90 cycles per minute
for 3-5 minutes. Adjust air pressure as
necessary to maintain 60-90 cycles per
minute.
Note
NOTE:
NOTE:
NOTE: High flushing fluid velocity is
the most important item for effective
cleaning. The fluid hose should
shake while the pump is running.
This is necessary to maximize the
cleaning effects of flushing.
e.
While pumping at 60–90 cycles per minute,
close then open the pilot ball valve (G) many
times to clean it. Each time the pilot ball valve
(G) is closed, close then open the fluid ball
valve (V) to flush the fluid ball valve. Ensure
fluid ball valve is open before opening pilot
ball valve (G).
Note
NOTE:
NOTE:
NOTE: When the fluid ball valve
gets hard to operate, it should
be disassembled, cleaned, and
re-packed with grease.
f.
Decrease air pressure to air motor back to
operating pressure.
g.
Close the air motor pilot ball valve (G).
h.
Place applicator outlet in a grounded metal
waste container.
i.
Open air motor pilot ball valve (G) to dispense
into grounded metal waste container.
