3.1 CLEAN/REPLACE SUCTION FILTER
Every 50 hours of duty: we advise you to dismant-
le the suction filter and clean the filtering element by
blowing compressed air on it (fig.13).
You are recommended to replace the filter element
at least once a year if the compressor operates in a
clean environment, but more frequently if in a dusty en-
vironment.
3.2 CONDENSATE DRAIN
The compressor generates condensate water which
accumulates in the tank.
The condensate in the tank must be drained daily by
opening the drain tap (fig.14) under the tank.
Periodical service inspection of the air receiver is ne-
eded, as internal corrosion can reduce the steel wall
thickness with the consequent risk of bursting.
Take care if there is compressed air inside the tank,
water could flow out with considerable force. Recom-
mended pressure: 1-2 bar max.
CONDENSATE MUST NOT BE DRAINED INTO
THE SEWER OR DISPERSED IN THE ENVIROMENT
AS IT CONTAINS OIL.
3.3 OIL CHANGE
We recommend a full change of oil within the first
100 hours of duty. Afterwards replace the oil every 300
hours.
Unscrew the oil drain plug on the housing cover, al-
low all the oil to flow-out, and re-screw the plug (fig.15 ).
Pour oil into the upper hole of the housing cover until
it reaches the level indicated on the stick or indicator.
Once a week: check oil level and top-up if necessary.
Use mineral oil ALTAIR. Do not mix different oils.
DO NOT DRAIN USED OIL INTO THE SEWER OR
DISPOSE OF IT IN THE ENVIRONMENT.

4. TROUBLESHOOTING
Loss of air in valve under pressure switch
It could depend on poor tightness of the check valve.
Take the following action (fig.16):
Discharge all pressure from the tank
Unscrew the hexagon-head of the valve
Carefully clean both the rubber disk (A) 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.

Reduction of performance. Frequent start-up. Low
pressure values.
Excessive performance request.
Check for any leaks from the couplings and/or pipes.
Intake filter may be clogged.
Replace the seals, clean or replace the filter.
Compressor turns but does not load
This may be due to failure of the valves or of a dama-
ged/broken head gasket.
Parts must be replaced by service centre.
Compressor no starting
If the compressor has trouble starting, check the fol-
lowing :
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)
Was the thermal-breaker tripped? (see 2.4)
Is power supplied to the electrical line?
Compressor not stopping
If the compressor does not stop when maximum
pressure is reached, the tank safety valve comes into
operation.
Stop the compressor and contact service centre.
5.1 TECHNCIAL DATA
• Check data label applied on compressor (fig.9).
• For the European market, compressors are manu-
factured in order to meet current directives and stan-
dards (see the declaration of conformity).
• The sound pressure level is measured in a free ran-
ge at a distance of 1 mt. ±3dB(A) at the maximum wor-
king pressure.
• The value of the sound level may increase from 1 to
10 dB(A) depending on the environment in which the
compressor is installed.
5.2 STORING THE COMPRESSOR
For the whole time that the compressor is not used
before unpacking it, store it in a dry place at a tempe-
rature between +5°C and + 45°C and sheltered away
from weather.
For the whole time that the compressor is not used
after unpacking it, place sheets over it to protect it.
The oil is to be replaced and the operational efficien-
cy of the compressor is to be checked if it is not used
for long periods.
5.3 PNEUMATIC CONNECTIONS
Make sure that pneumatic tubes for compressed air
with maximum pressure characteristics that are ade-
quate for the compressor used. Do not attempt to re-
pair faulty tubes.
5.4 DISPOSAL
Compressor and all materials (package, oil and spa-
re parts....) must be correctly disposed according to the
local laws.
