NAV41T.13EI, NAV41.13SA and NAV41T.13SA”
are NOT to be used for tyres inflation.
THIS MACHINE MUST BE USED
STRICTLY FOR THE INTENDED
PURPOSE IT WAS DESIGNED FOR
(AS INDICATED IN THIS MANUAL).
ANY OTHER USE WILL BE CON-
SIDERED IMPROPER USE. IN
PARTICULAR BEAD FITTING AND
INFLATING MUST BE CARRIED
OUT IN A SPECIALLY APPROVED
INFLATION CAGE.
THE MANUFACTURER CANNOT
BE HELD RESPONSIBLE FOR ANY
DAMAGE CAUSED BY IMPROPER,
ERRONEOUS, OR UNACCEPTABLE
USE.
AN INTENSIVE USE OF THE EQUIP-
MENT IN INDUSTRIAL ENVIRON-
MENT IS NOT RECOMMENDED.
2.1 Staff training
The machine may be operated only by suitably
trained and authorized personnel.
Given the complexity of the operations necessary to
manage the machine and to carry out the operations
safely and efficiently, the personnel must be trained
in such a way that they learn all the information
necessary to operate the machine as intended by the
manufacturer.
A CAREFUL READING OF THIS
INSTRUCTION MANUAL FOR
USE AND MAINTENANCE AND A
SHORT PERIOD OF TRAINING
WITH SKILLED PERSONNEL CAN
BE AN ENOUGH PREVENTIVE
PREPARATION.

3.0 SAFETY DEVICES
PERIODICALLY, AT LEAST MONTHLY, CHECK THE INTEGRITY AND THE FUNCTIONAL-
ITY OF THE SAFETY AND PROTECTION DEVICES ON THE MACHINE.
All the machines are equipped with:
• “man-operated” controls (immediate stop of operation when the control is released).
• Controls logic disposition
To prevent the operator from making dangerous mistakes.
• thermal magnetic switch on the supply line of the oil-pressure power unit motor: avoids the motor overheat-
ing in case of intensive use.
NO MODIFICATION OR CALIBRATION OF THE OPERATING PRESSURE OF THE MAXI-
MUM PRESSURE VALVE OR OF THE HYDRAULIC CIRCUIT PRESSURE LIMITER IS
PERMITTED
• controlled check valves on:
- opening of clamping unit jaws,
Such valves are installed to avoid that accidental oil leakages provoke unwelcome jaws movements (and as
a consequence the fall of the wheel).
• Fuses on the electric supply line of the clamping unit motor,
• Automatic power supply disconnection with the opening of the electric panel.
• Fixed guards and shelters
The machine is fitted with a number of fixed guards intended to prevent potential crushing, cutting and com-
pression risks. These protections have been realized after risks evaluation and after all machine operative
situations have been considered. These protections can be located in the figure below.
• Motor protection devices (versions with inverter)
The new “Invemotor” motor is equipped with electronic protection devices. They stop the motor if working
defected conditions appear to avoid that the motor itself can be damaged and that the operator safety can be
compromised (overvoltage, overload, overtemperature). For other details, see the chapt. 14 “Fault-Finding”.

3.1 Residual risks
The machine was subjected to a complete analysis of
risks according to reference standard EN ISO 12100.
Risks are as reduced as possible in relation with tech-
nology and product functionality.
Possible residual risks have been emphasized through
pictorial representations and warnings which placing is
indicated in “ PLATE POSITIONING TABLE” at page 9.
4.0 GENERAL SAFETY RULES
• Any tampering with or modification to the machine
not previously authorized by the manufacturer ex-
empts the latter from all responsibility for damage
caused by or derived from said actions.
• Removing of or tampering with the safety devices or
with the warning signals placed on the machine leads
to serious dangers and represents a transgression of
European safety rules.
• Use of the machine is only permitted in places free
from explosion or fire hazard and in dry places
under cover.
• Original spare parts and accessories should be used.
THE MANUFACTURER DENIES
ANY RESPONSIBILITY IN CASE
OF DAMAGES CAUSED BY UNAU-
THORIZED MODIFICATIONS OR
BY THE USE OF NON ORIGINAL
COMPONENTS OR EQUIPMENT.
• Installation must be conducted only by qualified
personnel exactly according to the instructions that
are given below.
• Ensure that there are no dangerous situations dur-
ing the machine operating manoeuvres. Immediately
stop the machine if it miss-functions and contact the
assistance service of an authorized dealer.
• In emergency situations and before carrying out any
maintenance or repairs, disconnect all supplies to
the machine by using the main switch.
• The machine electrical supply system must be
equipped with an appropriate earthing, to which
the yellow-green machine protection wire must be
connected.
• Ensure that the work area around the machine is free
of potentially dangerous objects and that there is no
oil since this could damage the tyre. Oil on the floor
is also a potential danger for the operator.

5.0 PACKING AND MOBILIZATION FOR
TRANSPORT
HAVE THE MACHINE HANDLED BY SKILLED
PERSONNEL ONLY.
THE LIFTING EQUIPMENT MUST WITHSTAND
A MINIMUM RATED LOAD EQUAL TO THE
WEIGHT OF THE PACKED MACHINE (SEE
PARAGRAPH “TECHNICAL SPECIFICATIONS”).
The machine is packed completely assembled.
The cardboard box containing the machine is fixed
onto a pallet and measures mm 2850x2100x1100.
The displacement must be performed through ad-
equate lifting device (pallet truck or fork lift truck). Lift
the packaging as indicated in Fig. 6 (forks introduced
in the middle to ensure a correct loads distribution).
6.0 UNPACKING
DURING UNPACKING, ALWAYS
WEAR GLOVES TO PREVENT ANY
INJURY CAUSED BY CONTACT
WITH PACKAGING MATERIAL
(NAILS, ETC.).
After removing the packing, and in the case of the ma-
chine packed fully assembled, check that the machine
is complete and that there is no visible damage. If in
doubt do not use the machine and refer to profes-
sionally qualified personnel (to the seller). The pack-
aging elements (plastic bags, polystyrene foam, nails,
screws, wood, etc.) must be collected up and disposed
of through according to the in force laws, except for
the pallet, which could be used again for subsequent
machine handling.
THE BOX CONTAINING THE FIX-
TURES IS CONTAINED IN THE
WRAPPING. DO NOT THROW IT
AWAY WITH THE PACKING.
7.0 MOBILIZATION
If the machine has to be moved.

8.0 WORKING ENVIRONMENT CONDI-
TIONS
The machine must be operated under proper condi-
tions as follows:
• temperature: 0° + 55° C
• relative humidity: 30 - 95% (dew-free)
• atmospheric pressure: 860 - 1060 hPa (mbar).
The use of the machine in ambient conditions other
than those specified above is only allowed after prior
agreement with and approval of the manufacturer.
8.1 Working position
In Fig. 8 it's possible to define working positions A,
B, C, D, which will be referred to in the description of
machine operative phases.
Positions A and B must be considered as main posi-
tions for tyre mounting and demounting and for wheel
clamping on the mandrel, while positions C and D are
the best positions to follow tyre bead breaking and
demounting operations.
Working in these positions allows better precision and
speed during operating phases as well as greater safety
for the operator.
8.2 Installation space
Fig. 9
Fig. 8
INSTALL THE MACHINE INDOORS OR IN A
ROOFED AREA. PLACE OF INSTALLATION
MUST BE DRY, ADEQUATELY LIT AND IN
COMPLIANCE WITH APPLICABLE SAFETY
REGULATIONS.
The location of the machine requires a usable space
as indicated in Fig. 8. The positioning of the machine
must be according to the distances shown. From the
control position the operator is able to observe all the
machine and surrounding area. He must prevent unau-
thorized personnel or objects that could be dangerous
from entering the area.
The machine must be fixed on a flat floor surface,
preferably of cement or tiled. Avoid yielding or irregu-
lar surfaces.
The base floor must be able to support the loads
transmitted during operation. This surface must have
a strength of at least 500 kg/m².
The depth of the solid floor must be sufficient to guar-
antee that the anchoring bolts hold.
8.3 Lighting
The machine does not require its own lighting for nor-
mal working operations. However, it must be placed
in an adequately lit environment.
For correct lighting, use lamps having total power
800/1200 Watt as envisaged by UNI 10380.
9.0 MACHINE ASSEMBLY
9.1 Anchoring system
The packed machine is fixed to the support pallet
through the holes prearranged on the frame. Such
holes can be used also to fix the machine to the ground,
through floor anchor small blocks (excluded from sup-
ply). Before carrying out the definitive fixing, check that
all the anchor points are laid down flat and correctly
in contact with the fixing surface itself. If not so, insert
shimming profiles between the machine and the fixing
lower surface, as indicated in Fig. 9.
