surfaces, use a workbench if available. For added protection use a suitable
residual current device (R.C.D.) at the socket outlet.
Note: If the mains cable requires replacing it must be replaced with an
G
identical one and fitted by a qualified person.

START-UP AND USE
• Check for correspondence between the compressor plate data with the
actual specifications of the electrical system. A variation of ± 10% with
respect of the rated value is allowed.
• Insert the plug of the power cable in a suitable socket (fig. 6) checking that
the button of the pressure switch located on the compressor is in the OFF
«O» position.
• Check the oil level by means of the oil dipstick (figures 7a- 7b), and if
necessary top up.
• At this point, the compressor is ready for use.
• Operating on the switch of the pressure switch (fig. 1), the compressor
starts, pumping air into the receiver through the delivery pipe.
• When the upper calibration value (set by the manufacturer) has been
reached, the compressor stops, venting the excess air present in the head
and in the delivery pipe through a valve located under the pressure switch.
This facilitates subsequent restart due to the absence of pressure in the
head. When air is used, the compressor restarts automatically when the
lower calibration value is reached (2 bar between upper and lower).
• The pressure in the receiver can be checked on the gauge provided (fig. 8).
• The compressor continues to operate according to this automatic cycle
until the switch of the pressure switch is turned.
• Always wait at least 10 seconds from when the compressor has been
switched off before restarting this.
• All compressors are fitted with a pressure reducer. Operating on the
knob with the tap open (turning it in a clockwise direction to increase the
pressure and in a counterclockwise direction to reduce this, fig. 9), air
pressure can be regulated so as to optimize use of pneumatic tools.
• The value set can be checked on the gauge.
• 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.
• Always pull out the plug and drain the receiver once you have completed
your work (figures 10-11).

MAINTENANCE

• BEFORE CARRYING OUT ANY OPERATION, ALWAYS PULL OUT THE
PLUG AND DRAIN THE RECEIVER COMPLETELY (figures 10-11).
• Check that all screws (in particular those of the head of the unit) are tightly
drawn up (torque 10 Nm = 1.02 Kgm).
The control must be performed before the first start-up of the compressor
and subsequently before the first intensive use in order to restore the
correct closing torque value modified as a result of heat expansion.
• After loosening any safety screws, clean the intake filter according to
the type of working environment and at least every 100 hours (figure
12). If necessary, replace the filter element (clogging of the filter reduces
compressor performance and an inefficient filter causes increased wear).
• Replace the oil after the first 100 hours of operation and every 300 hours

POSSIBLE FAULTS AND RELATED PERMITTED REMEDIES
FAULT
Leakage of air from the valve of the
pressure switch with the compressor off.
Reduction of performance. Frequent start-
up. Low pressure values.
The compressor stops and restarts
automatically after a few minutes.
After a few attempts to restart, the
compressor stops.
The compressor does not stop and the
safety valve is tripped.
Any other type of operation must be carried out by authorized Service Centers, requesting original parts. Tampering with the machine may impair its safety
and in any case make the warranty null and void.
Warranty and repair.
In the event of defective goods or requirements for spare parts, kindly contact the sales point where you made your purchase.
subsequently (figures 13a-13b-13c). Remember to check the oil level at
regular intervals.
Use SAE 40. (For cold climates, 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.
• Periodically (or after working with the compressor for more than an hour),
drain the condensate that forms inside the receiver (fig. 11) due to the
humidity in the air. This protects the receiver from corrosion and does not
restrict its capacity.
• Spent oil (lubricated models) and condensate MUST BE DISPOSED OF in
accordance with environmental protection regulations and current legislation.

or substitution of filtering
element
Change of oil
Tightening of head tension

Draining tank condensate
Safety valve
The safety valve has been set for the highest permitted pressure of the
pressure vessel. It is prohibited to adjust the safety valve or remove its
seal. Actuate the safety valve from time to time to ensure that it works when
required. Pull the ring with sufficient force until you can hear the compressed
air being released. Then release the ring again.
6. STORAGE
Pull the mains plug out of the socket and ventilate the appliance and all
connected pneumatic tools. Switch off the compressor and make sure
that it is secured in such a way that it cannot be started up again by any
unauthorized person.
Store the compressor only in a dry location which is not accessible to
unauthorized persons. Always store upright, never tilted!

7. DISPOSAL AND RECYCLING

The unit and its accessories are made of various types of material, such as
metal and plastic. Defective components must be disposed of as special
waste. Ask your dealer or your local council.
The compressor must be disposed in conformity with the methods
provided for by local regulations.
CAUSE
Check valve that, due to wear or dirt on the seal,
does not perform its function correctly.
Excessive performance request, check for any
leaks from the couplings and/or pipes. Intake filter
may be clogged.
Tripping of the thermal cutout due to overheating
of the motor.
Tripping of the thermal cutout due to overheating
of the motor (removal of the plug with the
compressor running, low power voltage).
Irregular functioning of the compressor or
breakage of the pressure switch.

Warning!
REMEDY
Unscrew the hexagonal head of the check valve, clean the
valve seat and the special rubber disk (replace if worn).
Reassemble and tighten carefully (figures 14a-14b).
Replace the seals of the fitting, clean or replace the filter.
Clean the air ducts in the conveyor. Ventilate the work
area. Reset the thermal cutout. On lubricated type
models, check oil level and quality.
Activate the on/off switch. Ventilate the work area. Wait a
few minutes. The compressor will restart independently.
Remove any power cable extensions.
Remove the plug and contact the Service Center.
