Problem

Probable cause

Solution

The compressor motor does 

not connect when reaching 

minimum pressure.

Damaged pressostat.

Make the substitution of the

pressostat.

There is pressure fall in the    

reservatory.

Connections leaking.

Generally this happens all 

along of the air line between 

compressor and the equip-

ment and not in the connec-

tions of the compressor. Fill 

the air compressor the máxi-

mum possible and with help 

of a sponge and detergent, 

apply a bit of foam on the 

connections, observe were 

are the leakages and remake 

the connection.

The compressor motor or the 

power cable presents super 

heating.

Electric net underdimen sio-

ned (wire with gauge smaller 

than recommended).

The electric net should 

be in conformity with the 

specifications  described  in 

the manual.

Air loss by the solenoid valve 

with the compressor sto-

pped.

Retention valve damaged or 

with residues interfe ring in 

its normal operation.

Unload the air contained in 

the reservoir, remove the re-

tention valve, disassemble it

and verify if the valve is da-

maged. If yes, change it, if 

no, make its cleaning.

Air loss by the valve sole-

noid with the compressor in 

operation.

Solenoid valve damaged or 

with residues interfering in 

it’s normal operation.

Unload the air contained in 

the reservoir, remove the 

solenoid valve, disassemble 

it and verify if the valve is 

damaged. If yes, change it, if 

not, make its cleaning.

The compressor emits exces-

sive noise with metallic and 

ritmic blows.

Bloqued bearing or motor 

excentric is loose of central 

shaft.

Make substitution of motor. 

Note: the head of the motor 

shall be sent to factory.
