Operation
Changing Empty Pails
(continued)
6. Lower the follower into the drumpail:
a. Move the ram hand valve lever to the DOWN
position.
b. Check the pail position as the follower lowers.
If necessary, stop lowering the follower before
contacting the pail, and adjust the pail position
to align the pail with the follower plate.
c. Continue lowering the follower. As the follower
enters the pail, loosen the air bleed stick.
Loosening the bleed stick allows trapped air
between the follower plate and the top of the
material to escape.
d. When air stops exhausting from the bleed stick
port, replace and tighten the bleed stick.
7. Adjust the ram air pressure for normal operation.
8. Bleed, from the pump, the air that was introduced
during the pail change:
a. Place a waste container under the pump bleed
port.
b. Open the bleed port and turn on pump air
pressure.
c. Allow material to flow from the bleed port until
it is air-free.
d. Shut off air to the pump and close the bleed
port.
e. Turn air on to the pump and set the pump air
regulator for normal operation.
