How to Set Up a Fitz®Mill Comminutor 

 

Most D6B machines are shipped completely assembled except for the machine legs, 
miscellaneous loose parts such as extra screens, dust retainers, accessories and spare 
parts, which are normally packed within a cardboard box, inside the machine packing crate. 
 
For stability, most D6B machines are shipped on special shipping legs (short legs), which 
must be removed by the customer.  The standard machine legs will be packed within the 
shipping crate and must be installed prior to placing the machine into service. 
 
Consult the REFERENCE DRAWINGS folder on your Operating Manual CD-ROM or hard-
copy book and review the layout, sub-assembly cross-sectional drawings and electrical 
drawings for your machine, prior to operation. 
 
The electrical components have been wired in accordance with information on the 

Comminutor Specification Sheet

.   Refer to section 4 “Electrical / Controls” for electrical 

installation and checkout information. 
 

CAUTION 

 

Check the machine for shipment damage.  Be sure the rotor moves freely, and that 
there is no apparent damage to controls, wiring or other devices. 

 

Keep in mind that this a high speed device requiring caution in operation and maintenance.  
Do not operate your Comminutor until you and your machine operator(s) have read this 
manual and are thoroughly familiar with its operation and use.
