Adjusting or Replacing Rotor Knives

CLEAN PARTS FOR REASSEMBLY

Clean the rotor knife seats with a stone or other non-mar- ring tool. Make sure that the backs of the knife seats are clean so that the rotor knife can be placed squarely against them.

Wipe the screws with lightly oiled cloth, do not leave an oil film since lubrication can adversely affect the stress on a screw installed to a fixed torque value.

DO NOT REPLACE THE MOUNTING SCREWS WITH ANY TYPE OF SCREW OTHER THAN THAT SPECIFIED BY STERLING. Substitution of improper screws could lead to premature failure, equipment damage, and serious injury to personnel.

When regrinding the knives, you may re-use the same screws and washers but do not re-use them more than six times. When installing new knives, replace the screws and washers with those furnished by the factory.

ROTORS WITH REPLACEABLE KNIFE SEATS
