MAINTENANCE

WARNING
CORMACH declines all responsibility in
the event of claims resulting from the use
of non-original spare parts or accessories.
WARNING
Do not attempt to modify the pressure set-
tings for relief valves or the pressure limiter
for any reason whatsoever. The manufactur-
er declines all liability for damage resulting
from tampering with these valves.
WARNING
Before adjusting or servicing the machine,
disconnect the electricity and compressed
air supplies and ensure that all moving parts
are suitably immobilised.
WARNING
Do not remove or alter any part of this ma-
chine (only technical assistance personnel
is permitted to do so).
DANGER
When the machine is disconnected from
the air supply, the devices bearing the sign
shown above may remain pressurised.
The purpose of the regulator filter unit plus
lubricator (FRL) is to filter the air, adjust the
pressure and lubricate it.
The "FRL" unit supports a maximum input
pressure of 18 bar and has an adjustment
range of 0.5 to 10 bar. The setting may be
modified by pulling the handle out and
then turning. After adjusting, return the
handle to the locked position by pushing
down (fig.35a).
The lubricant flow-rate is adjusted by turning
the screw on part "L", (fig.35b); normally this
unit is precalibrated to a pressure of 10Bar,
