Fault
A
Compressor does not start
after switching on
B Compressor shortly starts or
buzzes at the reach of the
switch-on pressure and then
switches off automatically
C
Compressor runs without stop
D In operation the relief valve
switch releases the
pressurized air
E After switch-off pressure is
reached the relief valve
under the pressure switch
releases the pressurized air
until the switch-on pressure
is reached
F
Compressor switches on
frequently
G
Safety valve blows off
H
Compressor heats too much
I
The oil level rises without oil
being added
J
Compressor is overheated and
it switches off
Cause
Pressure in the air receiver is higher than switch-
on pressure
Faulty feeding
Circuit breaker of the motor interrupts the power
feed
Faulty pressure switch
Electric cable is longer than permitted or is of too
small cross-section
Suction filter is contaminated heavily
Pneumatic tool has too high air consumption
Leak at the compressor
Too much condensing water in air receiver
Leaky pneumatic piping
Mud-discharge valve is open or missing
Leaky relief valve
Insert of the non-return valve is leaky or
faulty
Non-return valve is damaged
Too much condensation water in the air
receiver
Compressor is overloaded
Pressure in the air receiver is higher than set-up
switch-off pressure
Safety valve is faulty
Intake air is insufficient
Cooling ribs at the cylinder (cylinder head) are
dirty
Too long period of use
Condensation water accumulates in oil
High air humidity
Compressor is overloaded
Compressor is faulty
Compressor has under voltage
Ambient temperature 35°C
Remedy
Release the pressure from the air receiver so
that the pressure switch switches
automatically
Have the power feeding checked by an
authorized person
Have the pressure switch replaced by
an authorized person
Check the length and cross-section of
the electric cable
Clean or replace the suction filter
Check the air consumption of the pneumatic
tool; contact authorized reseller
Locate the leak, notify Güde service
Drain the condensing water
Check the pneumatic piping, seal the leak
Close or insert it
Clean or replace the relief valve
Clean or replace the insert of the non-return
valve
Replace the non-return valve
Drain the condensation water
Have the pressure switch readjusted
/replaced by an authorized person (Güde
Service)
Replace the safety valve or contact Güde
Service
Make sure that sufficient intake and outlet of
the air is guaranteed (minimum distance from
a wall 40 cm)
Clean the cooling ribs at the cylinder (cylinder
head)
Switch off the compressor
Compressor is overdesigned, notify the Güde
Service
Replace the oil
