MAINTENANCE
Failure
to
perform
the
specified
maintenance
can
result
in
inefficient
use
of
the
corn
head
and
a
consequent
waste
of
time.
The
recommended
maintenance
intervals
refer
to
average
working
conditions.
Perform
maintenance
more
frequently
when
working
with
the
combine
harvester
in
difficult
conditions,
due
to
external
factors
such
as
the
weather
or
the
type
of
field
harvested.
Maintenance
is
divided
into
two
types:
9.1
MAINTENANCE
DURING
THE
WORKING
SEASON
DAILY
MAINTENANCE
DURING
USE
Performing
checks
carefully
before
using
the
corn
head,
preferably
on
a
daily
basis,
prevents
breakdowns
and
delays
in
the
harvesting
processes.
Perform
the
following
checks
and
adjustments:
1.
lubricate
the
corn
head
according
to
the
instructions
indicated
in
the
"Lubrication"
section
of
this
manual.
Under
critical
conditions,
reduce
lubrication
intervals;
2.
check
the
integrity
and
proper
maintenance
of
electrical
insulation
and
plumbing;
3.
always
check
for
oil
leakages
or
ruptures
of
the
greasing
systems;
4.
check
the
tightening
torques
of
the
mechanisms
and
tighten
or
replace
as
required;
5.
always
check
the
integrity
and
the
proper
tightening
of
the
stalk
chopper
knives
which,
working
at
about
15
cm
from
the
ground,
may
break;
replace
immediately
if
broken.
IMPORTANT:
r
unning
the
corn
head
parts
without
introducing
it
into
the
harvesting
phase
can
cause
vibrations
or
metallic
noises.
In
this
case,
check
the
tightening
of
the
bolts
and
that
no
rotating
component
is
broken
or
not
properly
installed
(choppers
and
rollers
or
U
‐
joints
not
properly
inserted).
Failure
to
perform
this
check
can
result
in
breakage
inside
the
gearbox.
DANGER:
before
carrying
out
any
maintenance
work,
secure
the
machine
performing
the
following
operations:
‐
always
turn
off
the
engine,
‐
engage
handbrake,
‐
remove
the
ignition
key
and
engage
the
pipe
safety
lock
in
the
position
on
the
elevator
cylinder,
‐
hang
a
sign
reading
"DO
NOT
USE"
on
the
cabin
of
the
combine
harvester
.
Failure
to
engage
the
safety
lock
may
result
in
injuries
or
death.
All
maintenance
operations
are
to
be
performed
when
the
machine
is
disconnected
from
every
source
of
power
and
when
all
the
moving
parts
are
idle.
Use
suitable
PPE
for
each
of
the
operations.
