HYDRAULIC ROTATORS
GB

�������������
The
personnel
assigned
to
operate
the
machine,
before
starting
the
work,
must
have
studied
the
chapter
“Safety
Rules”.
This
is
especially
important
for
personnel
using
the
machine
only
sporadically.
Check
periodically
that
the
personnel,
while
working,
are
following
the
safety
and
accident
prevention
rules
indicated
in
the
instruction
manual.
Establish
the
responsibilities
of
the
operator
of
the
machine
and
authorise
him
to
refuse
to
follow
any
directions
given
by
other
persons
that
are
contrary
to
the
safety
rules.
Any
trainee
or
student
personnel
may
work
with
the
machine
or
the
system
only
under
the
constant
supervision
of
experienced
personnel.
8. OPERATION
Before
using
the
equipment,
read
all
the
information
in
the
chapter
“Safety
Rules”.
The
crane
and
the
rotator
must
be
used
following
all
the
safety
rules.
Do
not
subject
the
rotator
shaft
to
lateral
loads.
Maintain
a
working
angle
as
indicated
in
the
figure;
incorrect
positioning
of
the
working
angle
is
to
be
considered
dangerous
and
can
damage
the
shaft
of
the
rotator
itself.
- Lift
the
load
from
the
base
or
from
the
ground
before
proceeding
to
transfer
or
rotate
it.
- It
is
prohibited
to
leave
the
suspended
load
unattended.
- Make
sure
that
the
hoses
do
not
come
into
contact
with
obstacles
of
any
type.
- Breakage
of
the
hoses
or
a
nipple
can
cause
uncontrolled
rotation
and
the
load
could
be
dropped.
9. MAINTENANCE
Maintenance
must
be
a
scheduled
preventive
activity,
viewed
as
a
fundamental
requirement
for
the
purpose
of
safety,
with
the
assumption
that
the
machines
and
the
equipment
are
subject
to
wear
and
tear
that
is
a
potential
cause
of
breakdowns.
Therefore,
the
safety
of
the
machines
also
depends
on
good
preventive
maintenance
that
enables
the
replacement
of
parts
subject
to
wear
and
tear
before
any
operating
anomalies
appear.
All
maintenance
operations
must
be
carried
out
with
the
equipment
on
the
ground
and
the
machine
stopped
in
a
stable
position
with
the
engine
off.
9.1 Routine maintenance
Lubricate
the
pivot
of
the
upper
support
of
the
rotator
regularly.
Check
the
upper
support,
the
shaft,
the
hoses
and
the
nipples
once
a
week.
Make
sure
there
is
no
breakage.
At
least
once
a
year,
check
the
tightening
of
the
bolts.
The
rotator
cannot
be
repaired
with
weldings.
We
recommend
always
using
original
spare
parts.
Any
operation
of
maintenance
that
requires
disassembly
of
internal
components
of
the
rotator
must
be
carried
out
by
technical
personnel
authorised
by
FERRARI
INTERNATIONAL
S.p.A..
Hydraulic
fluid
according
to
DIN
51524
standard.
9.2 Overhauls
Must
be
carried
out
by
specialised
personnel
with
suitable
tools.
Possibility
of
residual
pressure
in
the
circuit:
before
any
operation,
discharge
the
pressure
of
the
machine
and
disconnect
the
equipment.
Failure
to
follow
the
instructions
given
below
may
cause
situations
of
danger
and/or
serious
damage
to
the
equipment,
making
it
unsafe.
- Do
not
overload
the
rotator!
Make
sure
that
the
maximum
lifting
load
of
the
crane
boom
does
not
exceed
the
limit
set
for
the
rotator.
- Make
sure
that
the
hydraulic
system
has
reached
the
operating
temperature.
