18” DRUM SERVICE
CUTTER SYSTEM

• Check the clearance between the knives
and the anvil. The clearance for the
knife to anvil should be between .070”
and .090” (1.78 – 2.29 mm). Use a
feeler gage that measures within that
range. The gage should fit easily
between the knife and the anvil without
force and without too much free space
on either side. Check clearance at each
corner of the knife. Check each knife.
• One person will need to be in the infeed
chute area to check the clearance on the
anvil and the knives; but not while the
drum is being rotated. Another person
will be under the chipper to make
adjustments. A third person will need to
rotate the drum to the next knife. The
drum will have to be rotated fully to
check all knife settings. DO NOT
ROTATE THE DRUM BY HAND
USE A PRY BAR.
• This is one time the cutter drum lock
pin will not be in position so extreme
care needs to be taken for safety. DO
NOT allow anyone in the infeed chute
area, until you make sure there is no
obstruction or binding in the cutter
drum by turning it around completely
first. If the cutter drum does not turn
freely, find and remove the
obstruction and then proceed.
