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 (fig. 31):
– Discharge all pressure from the tank
-Unscrew the hexagon-head of the valve (A)
-Carefully clean both the rubber disk (B) 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: (fig. 32)
-this may be due to failure of the valves (C1 – C2) or of a seal (B1 – B2): replace the damaged part.
Compressor not starting
If the compressor has trouble starting, check the following :
-Does mains power match that of the data-plate? (fig. 14)
-Are power cable extensions of adequate diameter or length?
-Is the work environment too cold? (under 0°C)
-For series PSV / BULLDOG: was the thermal-breaker tripped? (fig. 20)
-Is there oil in the housing to ensure lubrication? (fig. 11)
-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 flammable objects near the compressor.
-During down-times, turn the pressure switch to position "0" (OFF).
-Never aim the air jet at people or animals (fig. 34)
-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.(fig. 18 - 19)
-Transport the compressor, lifting or pulling it with the appropriate grips or handles (fig. 4 - 6)
-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. (fig. 35)
-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, it must be secured to prevent it
falling while in operation.
-Do not put objects or your hands inside the protective grilles to avoid injury to yourself or damaging
the compressor. (fig. 36)
-Do not use the compressor as a blunt object toward things or animals, to avoid serious damage.
-When you have finished using the compressor, always remove the plug from the power socket.
