the compressor runs or buzzes for
a short time and then switches off
automatically
Compressor running constantly
Compressed air is released from the
discharge valve under the pressure
switch when the appliance is being
operated
After reaching the cut-off pressure, air
is released from the discharge valve
under the pressure switch until the
closing pressure is reached
Compressor gets started too often
Safety valve blowing off
Compressor getting warm too much
Compressor being overheated and
keeps switching off
Causes
Pressure in the air jet exceeds the
closing pressure
Defective supply
Defective pressure switch
Worn carbons
Electric cable is too long or its cross
section is too small
Suction filter is very dirty
Pneumatic tools have high air con-
sumption
Leaking on the compressor
Compressed-air pipeline leaking
Drain valve is open or missing
Discharge valve is leaking
Check valve insert is leaking or defective Clean or replace the check valve insert
Check valve is damaged
Too much condensate in the air jet
Compressor is overloaded
Pressure in the air jet exceeds the set
cut-off pressure
Safety valve is defective
Air supply is not sufficient
Cooling fins on the cylinder (cylinder
head) are dirty
Too long time of appliance operation
Compressor is overloaded
Compressor is defective
Compressor under undervoltage
Outdoor temperature of 35°C
Removal
Release the pressure in the air jet so that
the pressure switch gets automatically
switched on
Have the current supply checked by an
authorised person
Have the pressure switch replaced by an
authorised person (Güde service centre)
Replace the carbons
Check the length and cross section of the
electric cable
Clean or replace the suction filter
Check the pneumatic tool air consump-
tion; seek an authorised compressed
air dealer
Localise the leaking, contact the Güde
service centre
Contact the Güde service centre
Close or insert the drain valve
Clean or replace the discharge valve

Have the pressure switch adjusted/
replaced by an authorised person (Güde
service centre)
