IMPORTANT:
BEFORE
MAKING
ANY
ADJUSTMENTS
OTHER
THAN
THOSE
SPECIFIED
IN
THE
USER
&
MAINTENANCE
MANUAL
PROVIDED
UPON
DELIVERY
OF
THE
MACHINE,
CONTACT
YOUR
OLIMAC
DEALER
.
Check
the
wear
of
the
knives
and
the
proper
timing
of
the
stalk
roller.
To
adjust
the
stalk
roller
knife,
make
sure
the
height
is
set
at
260
mm
at
the
point
shown
in
the
picture.
For
a
correct
grip
of
the
stalk,
the
roller
knives
must
be
set
as
follows:
at
the
front
(where
the
stalk
enters),
the
distance
between
the
opposite
blades
must
be
between
1.5
‐
2.5
mm
and,
at
the
rear
(near
the
gearbox),
the
distance
must
be
between
0
‐
0.5
mm.
Make
sure
that
the
blades
are
always
correctly
phased.
In
normal
working
conditions,
the
adjustment
of
the
stalk
roller
knife
should
usually
be
carried
out
every
600/800
hectares.
The
wear
of
the
knife
is
especially
visible
in
humid
conditions
(morning
or
evening)
and
you
will
notice
a
“dirty”
harvest,
with
foliage
and
stalks
clogging
the
main
harvester
feeder,
or
the
excessive
loss
of
small
corn
cobs
through
the
deck
plates.
A
programmed
adjustment
(600/800
hectares)
will
result
in
even
wear
of
the
knife
over
its
entire
length,
without
requiring
an
early
replacement.
