Operation
Starting and Adjusting the Pump
1.
Be sure the pump air regulator (M) is closed. Then
set the ram air regulator (18) to about 50 psi (350
kPa, 3.5 bar). Set the director valve (9) to DOWN.
See Fig. 3.
2.
Start the pump as explained in the separate pump
instruction manual.
3.
Keep the director valve (9) set to DOWN while the
pump is operating.
NOTE: Increase air pressure to the ram if the pump
does not prime properly with heavier fluids. If fluid is
forced out around the top wiper, ram pressure is too
high and the air pressure should be decreased.

WARNING
MOVING PARTS HAZARD
Moving parts can pinch or amputate your
fingers. When the pump is operating and
when raising or lowering the ram, keep
your fingers and hands away from the pump intake,
wiper plate, and lip of the fluid container.
To reduce risk of injury or damage to equipment,
take care when adjusting air release valve pres-
sure. Too much pressure can cause the ram plate
to rise very quickly or burst the drum. Too little
pressure can cause the ram to lift the entire drum
from the ground.
When the drum is empty, follow this procedure to load
a new pail of material.
1.
Stop the pump (A) by closing the pump air bleed
valve (G).
2.
Before raising the ram plate, locate the pushbutton
on the air release valve (14).
3.
Raise the ram plate out of the drum.
a.
Set the ram air regulator (T) to 0.07 to 0.10
MPa (0.7–1.0 bar) (10–15 psi).
b.
Set the director valve (U) to UP to raise the
ram plate. At the same time, carefully equalize
pressure in the drum by operating the air
release valve (14) open and closed.
4.
Raise the ram plate until it is completely out of the
drum.
5.
Remove the empty drum.
6.
Inspect the ram plate and, if necessary, remove
any remaining material or material build-up.
7.
Place the full drum on the ram base.
8.
Lower the ram and adjust the position of the drum
relative to the ram plate (C), as explained under
“Starting and Adjusting the Ram” on page 4.
Shutdown and Care of the Pump
1.
Set the director valve (9) to neutral.
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 4.
2.
Relieve the pressure.
3.
Follow the pump shutdown instructions in your
separate pump manual.
