BEFORE
STARTING
THE
FIELD
WORK
Run
the
following
checks
before

coupling
the
corn
head
to
the
combine
harvester
are
NOT
worn
nor
corroded;
2)
Clean
the
coupling
parts;
3)
Perform
lubrication
operations
(see
the
table
of
lubricants);
4)
Run
the
checks
on
the
main
machine
(combine

as
required
by
the

of
the
guards
and

key
and
set
the
feeder
safety
lock
in

on
the
lifting
cylinder
before
working
under
the
corn
head
or
the

safety
lock
can
cause

head
has
been
assembled
and
all
the
checks
are
performed,
the
corn

is
ready
to
be
used
in

Make
sure
that
all
safety
guards
and
shields
are
in
place
and
that
they
are
properly
secured.
Make
sure
that
the
total
mass
of
the
combine
harvester
and
the
corn
head
is
properly
distributed
on
the
axles
of
the
machine.
Starting
harvesting
1)
Place
the
corn
head
as
close
as
possible
to
the
harvesting

and
the
ground.
For
the

model:
2)
start
opening
the
machine
and
keep
the
hydraulic
system
command
pressed
for
a
few
seconds
after

Basic
adjustment
of
the
corn
head.
Due
to
their
construction
and
operating
purposes,
the
knife
stalk
rollers,
the
gathering
chains,
the
conveyer
screw
and
the
stalk
choppers
cannot
be
fully
protected.
For
this
reason,
a
safe
distance
MUST
be
kept
from
all
these
parts
during
operation.
All
operations
performed
on
the
machine
must
be
carried
out
with
caution,
with
adequate
equipment
to
prevent
accidents
and
carefully
following
the
safety
instructions
described
in
