WARNING
The “Spare parts” handbook does not authorise the user to carry out work on the
machine with the exception of those operations explicitly described in the user’s
manual, but enables the user to provide the technical assistance service with precise
information, in order to reduce delay.
MAINTENANCE
WARNING
Corghi declines all liability for claims deriving from the use of non-original spares or
accessories.
WARNING
It is expressly forbidden to attempt to alter operating pressure of the relief valves or
the pressure regulator.
The manufacturer declines all liability for damage resulting from tampering with these
components.
WARNING
Before making any adjustments or carrying out maintenance, disconnect the electrical sup-
ply from the machine and make sure that all moving parts are suitable immobilised.
WARNING
Do not remove or modify any parts of this machine except in the case of service in-
terventions.
DANGER
When the machine is disconnected from the air system, the devices bearing the above
plate may remain pressurized.
The FRL unit (filter, regulator and lubricator) is installed to filter the air, regulate its pres-
sure and lubricate it.
The FRL unit withstands a maximum input pressure of 18 bar and has a regulation range from
0.5 to 10 bar. The setting can be modified by pulling the knob to the OUT position and turning
it; after adjusting, return the knob to the locked position by pushing it down (fig.25a).
The lubricating flow-rate is adjusted by turning the screw on the element “L”, (fig.25b);
normally the unit is preset at a pressure of 10 Bar, with lubricant having viscosity SAE20,
so that one drop of lubricant is dispensed every 4 times the bead-breaker is operated
(check through the transparent cup).
