GB HYDRAULIC ROTATORS
�������������
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.
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.
- 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.
