EFA 001 606 885, Operation Manual

Operating instructions 

8

•

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.
