a. For S20 and D60: Open the main air slider
valve (BA) and set the ram air regulator (BB) to
40 psi (0.28 MPa, 2.8 bar). Set director valve

lubricant compatible with the fluid you will pump.
3. Put a full drum on the ram base and center it under
the platen (D).

platen, and remove the bleed stick to open the
platen bleed port (J).

appears at the platen bleed port (J) and close
the platen bleed port. Set the director valve to
neutral, reinstall the vent handle, and tighten
securely.
b. For L20c: Turn elevator director valve (DD) to
DOWN and continue to lower the ram until fluid
appears at the platen bleed port (J). Close the
