knives held in position
with
the
lock shims
and
set screws
(10).
Knives
must
be ad-
justed
to
set
evenly and level in the
cutterhead.
Before remov-
ing knives from cutterhead,
the
knife
gauge
should be adjusted
to
the
height
of
the
knives. so
the
height
of
the
knives will not
be changed relative to the
other
parts
of
the
head when the
knives
are
replaced . The feed rollers,
chipbreaker
and pressure
bar
are
adjusted
to the
arc
of
the

raised
or

adjusted
accordingly. Knives should
not
protrude
more

place
the
"jack
screw"
studs
in place
making
sure
the
"step"

knives have been set, final locking
of knives should be done by
rotating
cutter
head and locking all
shims uniformly.
CAUTION-If
one knife is locked tightly
before
the
others,
it
may
spring
the
cutterhead
and cause vi-
bration
or
uneven knife height.
IMPORTANT:
Knives should be kept
sharp.
The knive s
do
all
of
the
work
and
they
will
not
do

if
they
are
DULL. The sets of knives
are
matched and balanced
at
the
factory. When
the
knives
are
sharpened, care should be taken
that
they
are
kept
in balance.
