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.
