4.2 - Technical support service

Our technical support service will be happy 

to provide any information you require.

When ordering spare parts, you should 

in dicate the complete machine type, its 

serial number and the information indica-

ted on the nameplate.

Part  numbers  should  be  identified  from 

the exploded views and their description 

in the parts list.

Our extensive network of «service stations» 

can  dispatch  the  necessary  parts  without 

delay.

To ensure correct operation and the safety 

of our alternators, we recommend the use of 

original manufacture spare parts.

In the event of failure to comply with this ad-

vice, the manufacturer cannot be held res-

ponsible for any damage.
