Supply System Operation
Start and Adjust Ram
Moving parts can pinch or amputate fingers. When the pump is operating and when raising or lowering the ram, keep fingers and hands away from the pump intake, platen, and lip of the drum.
1.Set platen configuration based on pail type (see Adjust Spacers, page 13).
2.Refer to FIG. 1 and FIG. 2. Close all air regulators and air valves.
3.Open main air slider valve (BA) and set ram air reg- ulator (BB) to 45 psi (0.31 MPa, 3.1 bar). Set direc- tor valve handle (BC) to UP and let the ram rise to its full height.
4.Remove the drum cover.
5.Put a full drum of fluid on the ram base, slide it back against the drum stops, and center it under the platen (D). See FIG. 9.
NOTICE
To avoid damage to the platen seals, do not use a drum that is dented or damaged.

6.Remove bleed stick from platen bleed port (J).
NOTE: Some pails may require the spacer (EG) to be flipped upside down so the smaller diameter side is on the bottom. If unable to get ram into the pail, see Remove and Reinstall Wiper on page 14 to
7.Set the director valve (BC) to DOWN and lower the ram until fluid appears at the top of the platen bleed port (J). Adjust ram air regulator (BB) as needed.
Set the director valve (BC) to neutral and close the platen bleed port (J).
Start and Adjust Pump
To prevent equipment rupture, be sure all components are adequately sized and pressure rated to meet the system’s requirements.
1.Start and Adjust Ram, page 11. Keep the director valve (BC) set to DOWN while pump is operating.
2.Be sure the main air slider valve (BA) is closed. Then set the ram air regulator (BB) to about
3.Open main air slider valve (BA). Use air motor regulator (BE) to slowly increase pressure until pump operates at desired flow rate.
NOTE: Increase air pressure to the ram if the pump does not prime properly with heavier fluids. Decrease Ram air pressure if fluid is forced out around the top seal or platen.
