bed support pins are fully inserted and retaining rings are
installed on ends of the bolster pins before pressurizing
the cylinder or loading the press.
6.2 Removing Air From The Hydraulic System
NOTE: Air removal will go faster if hose(s) are bled of air before
connecting them to cylinder port(s).
Advance and retract the cylinder several times, avoiding pressure
build-up. Air is fully removed from the system when the cylinder
advances and retracts smoothly.
6.3 Hand Pumps
1. Close release valve finger tight
2. Operate the pump handle to build pressure. Pressure will
be maintained until the release valve is opened
3. Open release valve to release pressure.
6.4 Air Powered Pumps
Depress the pressure side of the treadle to activate the throttle
and advance the cylinder to desired stroke. To retract the cylinder
depress release.
6.5 Power Pumps
1. To advance the cylinder, shift valve to the advance position
and run the pump
2. Shift valve to neutral when desired stroke is reached
3. To retract the cylinder, shift valve to the retract position and
run the pump.
7.0 REPOSITIONING THE CYLINDER (see figure 3)
1. Loosen, DO NOT REMOVE , the wing nut (D) located under
the lower cylinder support bracket
2. Slide the cylinder mounting block assembly (A) to the
desired position on the press frame
3. Tighten wing nut (D) securely when cylinder is in the
