Operating instructions

•
The compressor starts automatically when
compressed air is drawn off and the pressure in
the storage tanks falls below a pre-set level. It is
therefore possible that the compressor does not
start up as soon as it is switched on, and that it
only switches off after a certain time delay (see
pressure switch).
•
The compressor stops automatically as soon as
full pressure is attained.
SWITCHING THE MACHINE OFF
CAUTION! Mistakes when switching off
Avoid causing damage to the electric motor, and
only ever switch the machine off at the starter
switch. Do not use the lockable master switch for
this purpose, and never pull the main plug out when
the machine is switched off.
⇒
Set the starter switch to the “0” position.
•
The motor and the compressor will now switch
off.
•
The compressed air line between the
compressor and the storage tank will let the air
off automatically, so as to ensure that the
compressor can start up again with no load
against it.
•
Pressure in the storage tank will be maintained.
⇒
Turn the lockable master switch off or plug off.
PROTECTING THE MOTOR FROM
EXCESSIVE TEMPERATURE
Warning!
unexpected start
Units with automatic pressure switch can start by
themselves once the unit has cooled down. This
means people are at risk. For this reason once the
motor protection has
been triggered off the unit should be turned off at
the operating switch.
If an excessive load on the machine or too high an
ambient temperature causes an excessively high
temperature in the electric motor, the motor cut-out
on the compressor will automatically shut the
machine down.
THE FOLLOWING STEPS MUST BE TAKEN
WHEN THE CUT-OUT HAS BEEN TRIGGERED
OFF:
⇒
Switch the machine off at the starter switch.
⇒
Discover and rectify the cause of the
malfunction.
⇒
Wait another 15 to 20 minutes for the motor to
cool down.
⇒
Reverse the motor protection switch on units
with manual motor protection.
⇒
Restart the machine.
