2.5 ADJUSTING THE WORKING PRESSURE
Pneumatic tools being used often requires lower pressure than the
maximum operating pressure. Always check correct pressure on to-
ol's manual.
On compressors supplied with a pressure reducer, operating pres-
Release the pressure reducer knob by pulling it up, adjust pressure
to the required value by turning the knob clockwise to increase pres-
sure and anti-clockwise to reduce it.
When you have obtained optimum pressure, lock the knob by pres-
sing it downward.
Pressure can be seen on the pressure gauge.
For pressure reducers equipped without a pressure gauge, the set
pressure can be seen on the graduated scale located on the reducer
body.
WARNING: Some pressure regulators do not have "push to lock",
therefore simply turn the knob to adjust the pressure.
For those models without pressure reducer, a suitable pressure re-
2.6 CAUTIONS WHILE USING
Do not 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 air tank.
Do not do any jobs on the compressor unless you have discon-
nected the power plug.
Temperature in operating ambient: 0°C +35°C.
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
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:
b) Make sure there is adequate exchange of air
c) Protect your nose and mouth with an appropriate mask.
If the electrical cable or plug are damaged, do not use the com-
pressor and contact an authorised service centre to replace the faulty
element with an original spare part.
Do not insert hands and/or any object inside protection grilles.
3. MAINTENANCE
Before attempting any maintenance jobs on the compressor,
make sure of the following:
Master power switch in position "0/Off".
Pressure switch off, in position "0/Off"
No pressure in the air tank
3.1 CLEAN/REPLACE SUCTION FILTER
Every 50 hours of duty
operates in a clean environment, but more frequently if in a dusty
environment.
cover. Unscrew the securing screws, remove the cover carefully, re-
restart the compressor.
3.2 CONDENSATE DRAIN
The compressor generates condensate water which accumulates
in the tank.
The condensate in the tank must be drained at least once a week,
Take care if there is compressed air inside the cylinder, and water
bar max.
CONDENSATE MUST NOT BE DRAINED INTO THE SEWER OR
DISPERSED IN THE ENVIRONMENT.
3.3 RECOMMENDED MAINTENANCE
In units with 2 poles, replace the whole connecting rod - piston unit
every 700-800 hours of operation.
In units with 4 poles, replace the connecting rod - piston unit every
1800-2000 hours of operation.
4. TROUBLESHOOTING
Loss of air in valve under pressure switch
It could depend on poor tightness of the check valve. Take the fol-
Discharge all pressure from the tank
Unscrew the hexagon-head of the valve (A)
Carefully clean both the rubber disk (B) and its seat.
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
It may be due to failure of the valves or a seal: please contact the
nearest service centre.
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 (see 1.5)?
Is the work environment too cold? (under 0°C)
Was the thermal-breaker tripped? (see 2.4)
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 rea-
ched, and the tank safety valve comes into operation. In this evenien-
ce please contact the nearest service centre.
