Chapter 1
Serial Number and Technical Support
1.1 The Serial Tag
1.2 Serial Tag location
To have access to the Serial Tag is necessary to lift the recovery tank.
The Serial Number is an extremely important information which has to be provided
each time a Technical Support is required or is necessary to buy spare parts or
accessories. The serial number is the only way to identify the machine by model,
production date type equipments in general.
