Starting and Adjusting System Rams
WARNING
PRESSURIZED EQUIPMENT HAZARD
To reduce risk of injury or equipment
damage:
D Make sure all material hose connec-
tions are secure.
D Check that all routing of air lines will
not interfere with any moving compo-
nents within the fixture.
D Do not pressurize the system until
you have verified the system is ready
and it is safe to do so.
1. Use following instructions to start and adjust
system rams.
2. Close all air regulators and air valves on supply
units being started. See Fig. 5.
3. Open main air bleed valve (E) and set ram air
regulator (T) to 2.8 bar, 0.26 MPa (40 psi). Move
director valve (U) handle so arrow points to UP,
and let ram rise to full height.
4. Remove drum cover. Smooth material surface with
straightedge.
5. Set full drum of fluid on ram base, slide drum back
against tube stop, and center under ram plate (C).
Use drum clamps (DD) to center, hold, and proper-
ly align drum with ram.
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,
ram plate, and lip of the drum.

Operation
To help avoid damage to equipment, do not use
drums that have side bungs or large dents with this
ram. Rough bung openings or large dents will dam-
age the wipers or stop the ram plate, resulting in a
runaway pump.
6. Move director valve handle to DOWN position to
lower ram. Lower ram until ram plate is just above
drum, then set valve to neutral position. Reposition
drum as necessary so wipers do not hit drum lip.
Open vent valve (CC) on ram plate.
7. Set director valve to DOWN position and lower
ram until fluid appears at vent valve (CC). Set
director valve to neutral and close vent valve.
Starting and Adjusting the Pump
1. Be sure pump air regulator (G) is closed. Set ram
air regulator (T) to 3.5 bar, 0.35 MPa (50 psi). Set
director valve (U) to DOWN. See Fig. 5.
2. Open the pump air bleed valve (H). Slowly adjust
the pump air regulator. This will start the pump and
fill the material passage.
3. Keep director valve (U) set to DOWN while 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.
