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 tyres.
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 tyres.
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 tyres 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 with extreme caution. Be
twice as careful in the descent phase since the unbalance towards the bottom in 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 loading platform, also rest the bucket on it lightly and
block the machine in a longitudinal direction by inserting wedges to the outside of the front and rear
axle tyres.
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.
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 UNDER THE 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.
