Operation
Starting and Adjusting the Pump
1. Be sure the pump air regulator (H) is closed. Then
set the ram air regulator (T) to about 2.1 bar, 0.21
MPa (30 psi). Set the director valve (U) to DOWN.
See Fig. 4.
2. Start the pump as explained in the separate pump
instruction manual.
3. Keep the director valve (U) set to DOWN while the
pump is operating.
NOTE: Adjust the air pressure to the ram as needed,
but do not increase it to a level where fluid is forced
past the wiper plate (C).
Changing Fluid Pails
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 wiper
plate to rise very quickly or burst the pail. Too little
pressure can cause the ram to lift the entire pail
from the ground.
When the pail 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 wiper plate, locate the pushbut-
ton on the air release valve (X).
3. Raise the wiper plate out of the pail.
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
wiper plate. At the same time, carefully equal-
ize pressure in the pail by operating the air
release valve (X) open and closed.
4. Raise the wiper plate until it is completely out of
the pail.
5. Remove the empty pail.
6. Inspect the wiper plate and, if necessary, remove
any remaining material or material build-up.
7. Place the full pail on the ram base.
8. Lower the ram and adjust the position of the pail
relative to the wiper plate (C), as explained under
“Starting and Adjusting the Ram” on page 11.
Shutdown and Care of the Pump
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 11.
1. Relieve the pressure.
2. Follow the pump shutdown instructions in your
separate pump manual.
