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
