6.0 OPERATION
6.1 System Set-up
WARNING: Check all press set-ups and load
fi xtures for safe operation.
Center the work piece and all parts of the set-up on the
line of force. If spacers are used in the set-up, they should
be constructed in one solid piece or tack welded together
for stability.
WARNING: Before operating the press, make
sure all 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.
