ADJUSTING OPERATING PRESSURE
You do not have to use the maximum operating pressure at all times. On the contrary, the pneumatic tool being used often
requires less pressure. Adjust pressure to the required value by turning the knob clockwise to increase pressure and anti-
clockwise to reduce it. Pressure can be seen on the gauge itself.
MAINTENANCE
Before attempting any maintenance jobs on the compressor, make sure of the following: – Master power switch in position
"0". – Pressure switch and the control unit switches all off, in position "0". – No pressure in the air tank. Every 50 hours of duty:
we advise you to dismantle the suction filter and clean the filtering element by blowing compressed air on it. You are
recommended to replace the filter element at least once if the compressor operates in a clean environment, but more
frequently if in a dusty environment. The compressor generates condensate water which accumulates in the tank. The
condensate in the tank must be drained at least once a week, by opening the drain tap under the tank. Take care if there is
compressed air inside the cylinder, and water could flow out with considerable force. Recommended pressure: 1 – 2 bar
max. Condensate of compressors that are oil lubricated must not be drained into the sewer or dispersed in the environment
as it contains oil.
OIL CHANGES – TOPPING UP WITH OIL
The compressor is filled with synthetic oil. We recommend a full change of oil in the pumping element within the first 10 hours
of duty. Unscrew the oil drain plug on the housing cover, allow all the oil to flow out, and re-screw the plug. Put oil into the
upper hole of the housing cover until it reaches the level indicated on the stick. Once a week: check oil level of the
pumping element and see if it needs topping up. For operation at ambient temperature in the range -5°C to +40°C, use
synthetic oil. The advantage of this oil is that is does not lose its characteristics either in winter or summer. Do not drain used
oil into the sewer or dispose of it in the environment.
WHAT TO DO IF SMALL MALFUNCTIONS OCCUR
Loss of air in valve under pressure switch This trouble depends on poor tightness of the check valve – take the following
action: – Discharge all pressure from the tank - Unscrew the hexagon-head of the valve - Carefully clean both the rubber
disk and its seat. - Refit all parts accurately.
Air losses These can be caused by poor tightness of a union – check all unions, wetting them with soapy water.
Compressor turns but does not load Coaxial compressors: - this may be due to failure of the valves or of a seal: replace the
damaged part. Pulley drive compressors: - this may be due to failure of the valves or of a seal: replace the damaged part.
Compressor no starting If the compressor has trouble starting, check the following : - Does mains power match that of the
data-plate? - Are power cable extensions of adequate diameter or length? - Is the work environment too cold? (under 0°C)
- For belt drive series the thermal-breaker tripped? - Is there oil in the housing to ensure lubrication? - Is power supplied to the
electrical line? (sockets well connected, thermal- breaker, fuses in good condition).
Compressor not stopping - If the compressor does not stop when maximum pressure is reached, the tank safety valve comes
into operation. To repair the valve, contact your nearest service centre.
IMPORTANT
- Do not on any account unscrew any connection while the tank is pressurised – always check if the tank is pressure free. -
Do not drill holes, weld or purposely deform the compressed air tank. - Do not do any jobs on the compressor unless you
have disconnected the power plug. - Temperature in operating ambient: 0°C +35°C. - Do not aim jets of water or
inflammable liquids on the compressor. - Do not place inflammable objects near the compressor. - During down-times, turn
the pressure switch to position "0" (OFF). - Never aim the air jet at people or animals - Do not transport the compressor while
the tank is pressurised. - Be careful with regard to some parts of the compressor such as the head and delivery tubes, as they
can reach high temperatures. Do not touch these parts to avoid burns. - Transport the compressor, lifting or pulling it with the
appropriate grips or handles - Keep children and animals well away from the machine operating area. - If using the
compressor for painting: a) Do not work in closed environments or near to naked flames b) Make sure there is adequate
exchange of air at the place of work c) Protect your nose and mouth with an appropriate mask. - If the electrical cable or
plug are damaged, do not use the compressor and contact an authorised service centre to replace the faulty element with
an original spare part. - If the compressor is located on a shelf or on a top above floor height, t must be secured to prevent it
falling while in operation. - Do not put objects or your hands inside the protective grilles to avoid njury to yourself or
damaging the compressor. - Do not use the compressor as a blunt object toward things or animals, o avoid serious damage.
- When you have finished using the compressor, always remove the lug from the power socket.

HINTS FOR EFFICIENT OPERATION
- For efficient operation of the machine at full continuing load and at maximum operating pressure, make sure the
temperature of the work environment indoors does not exceed +25°C. - We advise you to use the compressor at 70%
maximum duty per hour at full load as this ensures efficient operation of the product longterm.
