11
3.2 GENERAL STANDARDS FOR SAFETY AND USE
The present manual contains the information required to run the machine.
Contact the Manufacturer for any spare parts, accessories or information you might
require.
The tracked minitransporter fit with bucket or open dump body serves to carry and
dump materials.
The materials being handled must comply with the characteristics of the equipment
currently being used.
Avoid abrupt movements. All movements and maneuvers must be performed with
utmost care and while running at a slow speed.
Check that the work area is free and that there are no unauthorized persons
around. Also check that no one enters or passes within the machine operating
range.
In case of operating anomalies while moving the various mobile parts of the machine, turn
the engine off immediately.
Never perform any checks, controls or maintenance operations with the engine
running.
Never transport or lift anyone except the operator.
The operator can only be transported on the footboard only when running on a flat
surface which is paved or smooth and with a load in the bucket of at least 100 Kg.
When hoisting and transporting the machine, follow the instructions given in the
specific chapter.
Before starting up the machine, make certain that the load has been positioned
correctly in the dump body.
When moving over a slope, whether moving forward or in reverse, always make
certain that the weight is evenly balanced.
Never move over terrain that has both a lateral and longitudinal slope.
The terrain must always be solid and compact.

USE OF THE OPERATOR FOOTBOARD:
 The FOOTBOARD must be LIFTED (max height) while the OPERATOR is on the
GROUND.
 The FOOTBOARD must be LOWERED with the OPERATOR ON IT.
Never walk behind the unit while the footboard is lowered.
Whether the machine is running or off, to park the machine with full load on a
slope of more than 10%, insert a safety wedge at the tracks. The loaded
machine tends to descend on its own, whether the engine is on or off.
 WARNING !
WHEN STOPPING OR PARKING, ALWAYS TURN OFF
THE DIESEL ENGINE
Never use the machine at the rated maximum for excessively long periods of time. Always
alternate with periods operating at more moderate rates. In particular, to prevent damage
from overheating of the hydraulic parts, never make excessively long transfers.
> 10 %
WEDGE

14
Prevent foreign bodies (gravel, stones, debris, etc.) from wedging between the rubber
tracks as this would create interference between the various transmission bodies and
could damage or break them.
HAZARDOUS ZONES !
Because of its operating characteristics, the machine has some pinch points
(lowering the dump body onto the frame, bucket, tracks) and shearing points (dump
body hatch). Particular attention must be taken in using these movements. Never
place limbs or parts of the body in these areas.
If maintenance needs to be performed,
the lift body must be blocked with
special safety elements “S”, supplied
with the machine. They must be inserted
on the lift cylinder shaft. Always lock
with safety pin and plug.
Before parking the machine, set the
bucket on the ground and the body on
the frame to prevent the danger of
pinching or shearing.
In case of machines fitted with Hi-Tip
skip, to block the lifting scissor in upper
position, pull the elastic plug away from
the safety pin “S” and insert it into the
appropriate hole (ref.B). Always insert
the elastic plug. This enables to block
the body lifting chassis to make the
operation/work on the machine in total
safety.

3.3 LIFTING AND TRANSPORTING
See section 2.3 of this manual for the “overall dimensions of the machine”, while for the
loading on a lorry by using ramps, follow what explained below.
 Close the loading/unloading areas, forbidding the entrance to foreign people and
clearing the zone from obstacles and dangerous stuffs.
 Loading and unloading operations have to be done in a flat and compact 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 slipping.
 Check that the ramps are long enough to avoid problems during ascent and
descent of the machine. Particularly check the length of the ramps, taking note their
angle with the lorry loading platform has to be between 15° and 16° (30%).
 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 track.
 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.
 Load and unload the machine in correct driving ways, as explained below.
 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 with pivoting 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.
 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.

16
ATTENTION!!!
It is recommended to close the fuel valve every time the vehicle is transported or handled
in order to prevent causing harm or damage.
To load and unload the transporter from the truck, it is suggested to act as shown below.
Particular attention has to be taken during the overcome of the connection between the
ramps and the lorry loading platform, which can cause an excessive gradient.

3.4 HOISTING AND TRANSPORT
The machine must be lifted only when empty
and carefully following the indications below:
- There are four lift connections, two on the front of
the bucket and two on the sides of the driver's station.
(see figure).
- Fence off the lift area to prevent people from
accessing the zone: do not lift over people or things
and make certain that the area involved in the
loading/unloading operations is free of any obstacles
(electrical cables, telephone wires, etc.).
- Never walk or stand under hanging loads.
- Use cables or chains rated for the weight to be lifted:
when empty the machine fitted with bucket weigths
approximately 360 Kg. The machine fitted with high tip skip weights approximately 470
Kg.
- Hook up the 4 points on the machine and lift. Avoid abrupt movements and lift very
slowly.
- Lift the machine and position it on the transport vehicle. Then anchor it by inserting
wedges at the ends of the tracks and locking them to the base.
If it proves necessary, secure the machine to the load base with adequately rated steel
cables.
- To unload the unit, follow the above instructions in inverse order. Always take all safety
precautions necessary to ensure the safety of the people involved and of the machine
itself.
WARNING!
To prevent the possibility of injury or
property damage, we recommend
always closing the fuel tap whenever
the machine is transported or
moved.
For transport, always follow the
current Highway Code and
specific regulations in force in the
country where the unit is being
used.
