Daily System Startup; System Shutdown; Stopping The System; Restarting The System - Graco Uni-Drum Instructions Manual

NOTE: If the Pump does not prime properly, which may
occur with heavier, high viscosity fluids, increase the air
pressure with the RAM DOWN Air Regulator (AK).
NOTE: If fluid is forced out around the top wiper, ram
pressure is too high; decrease the air pressure with the
RAM UP Air Regulator (AJ).
NOTE: Ram pressure adjustments are carried out using
the dual REGULATOR Control Knobs (AC, AE) inside
the Pneumatic Logic Panel (G). The upper regulator
knob controls the downward pressure of the ram, and
the lower regulator knob controls the upward pressure
of the ram. See F . 5 on page 14.
