type servo-controls for traversing and manoeuvre of the arms and the bucket.
Movement is obtained using four rubber tracks with suitable tread to operate inside without dam-
aging the floor.
The machine is equipped with an open or closed driver’s cabin with heating plant and an incorporated
protective structure against tipping ROPS and against falling objects FOPS – 1st level.
FOPS 2nd level protection can be supplied on request for heavy duty and/or particular use; bolt in
replacement of the 4 eye-bolts.
MACHINE IDENTIFICATION
The machine is fitted with a special plate carrying the
identification data of the machine, riveted to the left
front side of the frame.
For any queries always quote the type and serial
number stated on the plate.
For further explanations, please consult the modes
on the Spare Parts Manual attached to the machine.
Other accessories which can be installed in the machine
will be provided with their nameplate, which can be seen
from the external part of the accessory.
For further information consult the documentation related
to the specific element.

OVERALL DIMENSIONS
TRANSPORT AND HANDLING
LOADING WITH RAMPS AND TRANSPORT BY TRUCK
The machine loading and unloading operations must be carried out on a compact and level
surface.
Check that the transport vehicle is in perfect condition. Apply the hand brake and insert safety
wedges at the front and rear of the rear axle tyres.
The vehicle engine must be off and the key removed from the ignition. The body must be level.
Position the machine at the rear of the truck, ensuring that the longitudinal axle coincides with that of
the truck.
Check that the ramps are suitable for the vehicle to be loaded. Only use homologated and/or
certified ramps.
Check that the ramps are perfectly clean and free of grease and that there is no risk whatsoever of
the tracks .
Check that the ramps are long enough to avoid problems during ascent and descent of the machine. The
length of the ramps must be such that their inclination with respect to the height of the truck loading
platform is between 15º and 16º.
Check that the ramps are properly coupled to the transport vehicle and appropriately
spaced.
The width of the ramp must be such as to allow comfortable passage of the tracks .
Page 6of 61
Item – Rev(s): 8009641121– 101

The ascent and descent operations must always be carried out with the machine running and the
hydraulic oil at operating temperature.
Do not use the ramps as a gangway for crossing from one vehicle to the next.
For loading and unloading of the machine it is recommended to ascend in reverse gear and descend in
forward gear. In both cases it is recommended to keep the arm lowered and the bucket turned
downwards, parallel to the ramps. Block the eventual lowering of the loading platform with a truss or
other equipment.
Before ascending or descending, check perfect alignment between the tracks and the ramps. Do
not steer or adjust direction while on the ramps. If necessary, return to the point of departure,
repositioning correctly.
Caution of passage in the connection area between the ramps and the loading platform of
the truck; the steep slope must be negotiated by moving very slowly and withextreme caution.
Be twice as careful in the descent phase since the unbalance towards the bottomin this case is much
higher. It is recommended to lower the arms and turn the bucket forwards to allow eventual
emergency shutdown.
All the loading and unloading operations of the machine must be carried out and co- ordinated by
at least a second person who controls good progress of the operations.
TRANSPORT
Once the machine has been positioned on the load plane, lightly rest the bucket and proceed to
blocking the machine lengthwise by inserting wedges in front of and behind the track rollers.
For transversal and vertical blocking use belts to prevent lateral and vertical movement
owing to jolts during transport.
Measure and check the maximum height of the load. During transport always follow the road
regulations and the specific regulations in force in the various countries of transit.
LIFTING
Check that the cabin is correctly fixed to the frame before lifting the machine.
Use the 4 supplied eye-bolts to lift the machine, by fixing them to the special seats located on the roof
of the cabin.
Page 7of 61
Item – Rev(s): 8009641121– 101

If the eyebolts are removed, close the four seats with the plastic caps supplied. Any
infiltration of water could seriously damage the electrical system of the right-hand
and left-hand dashboard.
Restrict the lifting area, prohibiting access to foreign personnel. Do not pass over persons or things and
ensure that the loading area is free of any obstacles (electric and telephone cables, etc.).
IT IS STRICTLY PROHIBITED TO WALK OR STAND UNDERTHE SUSPENDED LOADS.
- Use cables or chains with adequate capacity for the load to be lifted.
- Attach the ropes or chains to the previously bolted eye-bolts and proceed with lifting avoiding
sudden movements and dangerous machine swaying.
- During transport follow the instructions previously recommended.
PRESCRIPTIONS FOR CIRCULATION ON ROADS
For correct road circulation comply to all specified below.
1. Flashing lights.
2. Shovel blocking pin in maximum lifting position
3. Shovel sharp edge lateral and front protections.
4. Plate positioning.
5. Frame number punching area.

PRESCRIPTIONS
- Working system commands must be blocked. Involuntary lifting of
arms is prevented by the hydraulic block inserted on start-up of the
machine.
- Disconnection and insertion is controlled by a button (ref. 4) on the
right command panel.
- Obligation for approved yellow flashing light. This functions even
when the use of a lighting device is not obligatory.
- Front loading shovel in max. lifting position and blocked to the frame using the special retainer.
- The shovel’s sharp edge must be protected by a special protection indicated with red and white
reflective stripes.
- The working lights must always be switched off.
- In each case the prescriptions inserted into the vehicle registration document and in the Highway
Code must be respected.
