9-5 Rotor Knife Sharpening
The rotor knives must be sharpened to within .003”
(0.076 mm) of each other. Greater dimensional variations
prevent the proper setting of the knife gap and may create
other serious complications.
Grinding the cutting edge until it is free of nicks can be
wasteful. It is not harmful to allow small nicks to remain in
the cutting edge.
WARNING!
Do not install rotor knives that are smaller than the minimum dimension shown,
because the fasteners that secure these knives may interfere with the cutting circle.
The rotor will not be able to rotate and the knives will be damaged.
It is important to note that the minimum dimensions given for the rotor knife and bed
knife cannot be combined simultaneously to produce a cutting combination.
NOTE: Replacement knife sets and knife resharpening services are
available from Sterling . Contact the Customer Service
Department at [phone].
