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 acces-
sories.
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 supply
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 inter-
ventions.
DANGER
When the machine is disconnected from the air
system, the devices bearing the above plate
may remain pressurized.
The FRL unit (fi lter, regulator and lubricator) is
installed to fi lter the air, regulate its pressure
and lubricate it.
The FRL unit withstands a maximum input pres-
sure of 18 bar and has a regulation range from 0.5
to 10 bar. The setting can be modifi ed by pulling
the knob to the OUT position and turning it; after
adjusting, return the knob to the locked position
by pushing it down (fi g.25a).
The lubricating fl ow-rate is adjusted by turning
the screw on the element "L", (fi g.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).
