Adjusting or Replacing Bed Knives

CLEAN THE KNIFE MOUNTING SURFACES

Clean the knife mounting surfaces with a stone or other non-marring tool and wipe them with a clean cloth.

Make sure they are free of all material, dust, and dirt.

DO NOT REPLACE THE MOUNTING SCREWS WITH ANY TYPE OF SCREW OTHER THAN THAT SPECIFIED BY CUMBERLAND. 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.

REPLACE THE UPSTROKE BED KNIFE

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

Install the upstroke knife making sure to install it with the knife-edge on the lower side.

Engage the captive screws in the slots on the far side of the knife bed and lower the knife onto the knife bed-

Repeat these steps for the second half of the knife.

REPLACE THE UPSTROKE KNIFE CLAMP

Place the clamp over one half of the knife and hold it in position until you fasten the first two screws and washers finger-tight.

Place the second clamp over the second half of the knife and hold it while you fasten it. Install the remaining mounting screws and washers and tighten them finger-tight.
