5.3 AIR DISCHARGE
After the first start-up, or after maintenance carried out on elements of the system
(e.g. cylinders, filters, pipes, changing oil) a considerable quantity of air may be
present in the circuit.
Irregular operation, noise, and/or uneven cylinder movement highlight the presence
of air.
It is necessary to discharge the air as follows:
-
Pump ram down to the maximum stroke.
-
Loosen the upper nipple of the press cylinder and wrap it in a cloth to
avoid oil splashes.
-
Stroke the hand pump to remove the air.
-
Verify that all the air has been bled out of the system when only oil is
expelled from the fitting.
-
Tighten the nipple.
This operation must be continued until oil is completely free of air bubbles or froth.
After discharging the air, it is necessary to top off the oil level in the unit.
5.4 MAXIMUM PRESSURE ADJUSTMENT
The maximum work pressure of the press is adjusted by pressure regulator valve
suitably set and sealed with lead.
