Güde 231/8/24 6TLG Mode D'emploi Original page 15

After each use
clean the air holes and mobile parts off dust.
Regularly
paint metal parts with oil (universal oil)
check whether all screws are tightened.
Regularly (once a month at least) release the condensed
fluid from the air jet; failing to observe this regulation may
lead to guarantee for rusting through expiry – apart from
that, the compressor is maintenance-free.
(The condensed fluid may be brown-coloured due to
surface layer from the air jet)
1. Pull the connector plug out of socket!
2. At low pressure in the air jet open the bleeder (9)
(max. of 1 bar) and completely empty the condensed
fluid (use a suitable container)
3. Close the valve.
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
under the pressure 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
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
• Air filter
Sometimes it is necessary to clean the filter bed. For that purpose
remove the air filter cover screw and remove the foam filter. Wash
it in warm soap water solution. Let the foam filter dry and reinsert
it to its place. Now assemble the air filter cover again.
Fuse against overheating: (depending on model)
If the compressor is loaded by a technical defect or possibly also
by continuing operation, the power feed will be automatically
interrupted by a thermo-switch. If such situation occurs it is
advisable to disconnect the compressor from the mains and let it
cooled down for approx. 5 minutes. If the compressor does not
start after certain period of operation, let it cooled down for
additional 3 minutes.
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
