any damage in transit inform the dealer.  
Caution!  
The voltage specified on the model rat-  
ing plate must correspond to the voltage sup-  
plied.  
– Do not dispose of the packaging with the  
household rubbish, hand it in at the appro-  
priate collection point for recycling.  
Caution!  
The maximum tolerable mains  
impedance at the electrical contact point (see  
Technical Data) must not be exceeded.  
Check the oil level  
Caution!  
Read the oil level displayed while unit is at  
a standstill. The oil level must be above the  
two indicators.  
Use an extension cable with a sufficient  
cable cross-section (see Technical Specifica-  
tions) and unwind it fully from the cable drum.  
Activate the oil reservoir vent  
Unscrew the fastening screw of the hood  
For connected loads see model rating plate/

and remove the hood.  
Caution!  
It is essential that the unit is connected  
to the power supply by means of a plug. An in-  
separable connection to the power supply is  
prohibited. The plug is used to disconnect  
from the mains.  
Cut off the tip on the cover to the oil reser-  
voir.

handle.  
Pay attention to the regulations of the  
water supply company; according to DIN  
1988, the unit may not be connected direct to  
the public drinking water supply. A short-term  
connection via a non-return valve  
(Order no. 6.412-578) is allowed.  
Tighten the high-pressure hose according-  
ly.  
For connected loads see Technical Specifica-  
tions.  
Connect a supply hose (not supplied) to the
