CAUTION

 

Cutting injuries to hands and fingers! 

The sheet metal parts of the housing may have sharp corners and edges. 

 

Wear protective gloves. 

Burns to hands and fingers! 

The motor temperature increases during operation, reaching in excess of 40 °C! 

 

Allow the MILOMAT  (motor) to cool down adequately after operation, or wear 

protective gloves. 

 

NOTE

 

Keep all screws and removed small parts carefully. 
Metallic housing parts must be connected to the protective earth conductor. 
In this connection, make sure that 

 

all original parts are reinstalled in the location intended for them. No excessively 

long screws are used, since these can cause short circuits or damage components 

inside the housing. 

 

all grounding cables are reconnected and all screws are firmly tightened.
