Activating the compressor
The motor builds up the required pressure and is ready for operation after 40 to 240 seconds (depen-
ding on the compressor type).
The compressor is fitted with an automatic shut-off switch. The shut-off switch automatically deacti-
vates the motor after it has built up the maximum pressure required.
The motor is automatically reactivated when the pressure reaches four to six bar in the event of air
being removed from the pressure tank.
Warning:
All compressors are fitted with a safety valve. This should not be removed or alte-
red. Repair or replacement of the safety valve should be entrusted to a qualified
specialist workshop.
Setting the working pressure
(see Fig. 6, Page 52)
The desired working pressure can be set with the pressure regulator. The working pressure is indica-
ted on a pressure gauge
1. Pull the knob upwards.
2.
Increasing the pressure:
Turn the knob in a clockwise direction.
Reducing the pressure:
Turn the knob in an anticlockwise direction.
3. Push the knob downwards again after the desired working pressure has been set.
Motor circuit breaker switch
All compressors are fitted with a motor circuit breaker. This automatically deactivates the motor in the
event of overloading or overheating to protect the unit against damage.
Proceed as follows in the event of the compressor being switched off during normal operation:
1. Turn the on/off switch to 0 ("OFF") and allow the unit to cool for approx. 30 minutes.
2. The unit can be switched on again after approx. 30 minutes.
Deactivating the compressor
The unit should be deactivated if the compressor is not used for a longer period of time.
Warning:
The unit should be deactivated if it appears not to be operating (i.e. the motor is not
running). This is the case if the motor has built up the required maximum pressure
and the automatic shut-off switch has been triggered. The motor is in standby mode
and activates immediately again if the pressure drops below a particular value.
Turn the on/off switch to the 0 position ("OFF") to deactivate the unit.
Maintenance work
The following maintenance work should be realised at the recommended intervals to increase the ser-
vice life of your compressor.
Warning:
The unit should be disconnected from the electrical power supply prior to commen-
cing maintenance work.
Weekly
Check the oil level
Check the oil level in the oil inspection glass once a week while the compressor is switched off and
top up with the required volume of oil if necessary (see "Filling oil").
