CONNECTION TO THE COMPRESSED 
AIR MAINS 

Warning

! 

- Pressure in the mains 

The compressed air mains might be under 
pressure, and working on mains that are under 
pressure can result in injury. Therefore, first shut 
the mains off from all sources of pressure and let 
the air out. 
 

Compressed air connection with flexible 

hosepipes 

Use a suitable flexible hosepipe for connection to 
the compressor. This will prevent tension from 
causing cracks, and also noise from being 
transmitted. 
 
Connecting pipes and couplings of the right size 
and grade for the relevant operating pressures and 
temperatures must always be used, and 
components that are in a faultless condition. 
 

CONNECTION TO THE ELECTRIC 
MAINS 

Warning

! 

- drive belt guard 

Wheels, drive belts, and fan blades can cause very 
severe injuries when the are in motion. The 
compressor must never be given a trial run or 
started up unless the drive belt guard is in place 
and the housing closed. 

Exception: Machines with a sound-insulation 
hood 

can be run with side cover open to check the 

direction of rotation, but this must be done very 
carefully.

 
INSTRUCTIONS FOR MACHINES WITH SOUND-
INSULATION HOOD 
Machines which are fitted with a sound-insulation 
hood are also fitted with ventilation fan to prevent a 
build-up of heat. After the machine has been 
switched off, this fan continues to run for a short 
time until the machine has cooled down. 

INSTRUCTIONS FOR ELECTRICAL 
CONNECTION 

•

The electrical connection and safety precautions 
must comply with VDE regulations and/or other 
regulations in force in the country of operation, 
including those issued by the local power supply 
utility. 

•

Always check the direction of rotation before 
starting the compressor up. 

•

Units connected without a plug connection 
should be fitted with a lockable main switch as 
well as a suitable main fuse. 

•

Please refer to the technical data for the 
necessary cross-sectional size of the wiring and 
the rating of the fuse. 

 
CHECKING THE DIRECTION OF ROTATION 

⇒

  Switch the machine on or plug it in. 

⇒

  Turn the master switch on and immediately off 

again. 

⇒

  If the ventilator wheel turns in the direction of the 

arrow, this is correct; if not, reverse the poles on 
the motor. 

STARTING UP AND OPERATING 

STARTER SWITCH 

Warning

! 

- hot surfaces

The compressor block and the air leads coming 
from it can become very hot during operation. Avoid 
the risk of burns, and do not touch the hot parts of 
the compressor. 

Warning

!

 - drive belt guard 

Wheels, drive belts, and fan blades can cause very 
severe injuries when the are in motion. The 
compressor must never be started up unless the 
drive belt guard is in place and the housing closed. 

SWITCHING THE MACHINE ON 

⇒

  Check the starter switch - it must be set at the 

“0” position. 

⇒

  Check the oil level. 

⇒

  Switch the master switch on or plug in. 

⇒

  Set the starter switch to the “1” position, and the 

machine is now ready to operated.
