pressure can be regulated in order to optimize use of air-powered tools
operating on the knob with the valve open (pulling it up and turning it in a
clockwise direction to increase pressure and counterclockwise to reduce
this) (
fig. 8
). Once you have set the value required, push the knob down to
lock it.
• The value set can be checked on the gauge (for versions equipped with
this,
fig. 9
).
•
Please check that the air consumption and the maximum working
pressure of the pneumatic tool to be used are compatible with the
pressure set on the pressure regulator and with the amount of air
supplied by the compressor
.
• When you have finished working, stop the machine, pull out the plug and
empty the reservoir.

AIR RECEIVER (ON TANK-MOUNTED UNITS)
• Corrosion must be prevented: depending on the conditions of use,
condensate may accumulate inside the tank and must be drained every
day. This may be done manually, by opening the drain valve, or by means
of the automatic drain, if fitted to the tank. Nevertheless, a weekly check of
correct functioning of the automatic valve is needed. This has to be done
by opening the manual drain valve and check for condensate (
fig. 13
).
• Periodical service inspection of the air receiver is needed, as internal
corrosion can reduce the steel wall thickness with the consequent risk
of bursting. Local rules need to be respected, if applicable. The use of
the air receiver is forbidden once the wall thickness reaches the minimum
value as indicated in the service manual of the air receiver (part of the
documentation delivered with the unit).
• Lifetime of the air receiver mainly depends on the working environment.
Avoid installing the compressor in a dirty and corrosive environment, as
this can reduce the vessel lifetime dramatically.
• Do not anchor the vessel or attached components directly to the ground
or fixed structures. Fit the pressure vessel with vibration dampers to avoid
possible fatigue failure caused by vibration of the vessel during use.
• Use the vessel within the pressure and temperature limits stated on the
nameplate and the testing report.
• No alterations must be made to this vessel by welding, drilling or other
mechanical methods.

MAINTENANCE
• The service life of the machine depends on maintenance quality.
•
PRIOR TO ANY OPERATION SET THE PRESSURE SWITCH TO THE
OFF POSITION, PULL OUT THE PLUG AND COMPLETELY DRAIN THE
RESERVOIR.
• Check that all screws (in particular those of the head of the unit) are
tightly drawn up (
fig. 10
). The check must be carried out prior to the first
compressor starting.

• Clean the suction filter according to the type of environment and in any case
at least every 100 hours. If necessary, replace the filter (a clogged filter
impairs efficiency while an inefficient filter causes harsher wear on the
compressor
(figures 11a - 11b)
.
• Change the oil after the first 100 hours of operation and subsequently every
300 hours. Check the oil level periodically.
• Use
API CC/SC SAE 40
. (For cold climates,
API CC/SC SAE 20
is
recommended). Never mix different grade oils. If the oil changes color
(whitish = presence of water; dark = overheated), it is good practice to
replace the oil immediately.
• After topping up, tighten the plug (
fig. 12
) making sure that there are no
leaks during use. Once a week, check the oil level to assure lubrication in
time (
fig. 7a
).
• Periodically, check the tension of the belts which must have a flexion (f) of
around 1 cm (
fig. 14
).

POSSIBLE FAULTS AND RELATED PERMITTED REMEDIES
Request the assistance of a qualified electrician for operations on electric components (cables, motor, pressure switch, electric panel, etc).
FAULT
CAUSE
REMEDY
Air leak from the valve of the pressure switch.
Check valve does not perform its function
correctly due to wear or dirt on the seal.
Unscrew the hex-shaped head of the check
valve, clean the housing and the special rubber
disk (replace if worn). Re-assembler and tighten
carefully (
figures 15a-15b
).
Condensate drainage cock open.
Close the Condensate drainage cock.
Rilsan hose not inserted correctly in pressure
switch.
Insert the Rilsan hose correctly inside the
pressure switch
(fig. 16)
.
Reduction of efficiency, frequent start-up. Low
pressure values.
Excessively high consumption.
Decrease the demand of compressed air.
Leaks from joints and/or pipes.
Change gaskets.
Clogging of the suction filter.
Clean/replace the suction filter
(
figures 11a-11b
).
Slipping of the belt.
Check belt tension
(fig. 14).
