5. UNPACKING AND PREPARATION
The Chipper model TRX 50 / TRX 50 S can be supplied on pallets to
facilitate handling and transport to its final location.
Onsite handling of the pallets requires means with a minimum capacity of
100 kilos.
Machines with a universal joint can be hooked up and carried using the
three-point hitch of the tractor.
All machines can be lifted and transported by means of cranes or winches,
using hooks and cables, which must be approved and of an adequate
capacity. Hook up to the lugs, as shown in the pictorial affixed to the
machine.
Only safe hooks, such as snap hooks, must be used for lifting. Take great
care and exercise extreme caution when loading and unloading the
machine. These operations must only be carried out by qualified personnel
(slingers, truck operators, etc.). Never pass or stand underneath the
machine when it has been raised off the ground.
Avoid:
•hoisting the chipper with ropes or unsuitable hoists;
•dragging the chipper;
•bumps or shocks;
•exposing the machine to rain, frost or other unsuitable weather
conditions.
On taking delivery, check that the contents correspond to the delivery note.
If you note any damage or deformity due to transport, make an immediate
complaint to the carrier and advise the authorized dealer or the
manufacturer. In particular, check the machine for:
•dents, knocks or signs of deformation;
•damp areas or signs indicating that the pack has been exposed to foul
weather;
•signs of tampering.
The machines are equipped with two wheels to allow short trips within the
place of use.
When the machine is being transported, it needs to be tilted slightly
backwards, with one foot on the wheel axle acting as a lever and holding
the hopper so as to balance the weight.

7.2 SPECIFIC SAFETY AND ACCIDENT PREVENTION
RULES
7.2.1 Petrol and diesel versions
•If there is a malfunction, switch off the engine and remove the spark plug cable
before carrying out any maintenance, adjustment or cleaning operations (e.g.
removing foreign bodies from the hopper).
•Before setting to work, read through and follow the instructions in this manual
and the accompanying engine manual.
•Never use the machine in enclosed or poorly ventilated areas (even if the doors
and windows are open), as the exhaust fumes are toxic.
•Avoid smoking and lighting flames when filling with petrol.
•Always fill the fuel tank in an open area with the engine switched off. Remember
that petrol is highly flammable, and explosive under certain conditions. Fuel must
be stored in suitable canisters.
•Never place anything on the engine as it could catch fire.
•Never remove the fuel tank cap or top up with petrol with the engine running or
when it is still hot.
•If any petrol gets spilt, do not attempt to start the engine immediately.
•The exhaust pipe gets very hot when the engine is running and remains hot for
some time after it is switched off. Never touch the exhaust pipe. Keep to a safety
distance.
7.2.2 Motor-cultivator models
•Any maintenance, adjustment or cleaning operations (e.g. removal of
foreign bodies from the hoppers) must be done with the machine
standing firmly on the ground, the motor-cultivator engine switched off,
the hand brake engaged, and the ignition switched off and the key
removed.
•Never stand between the motor-cultivator and the machine when the
engine is on and the power take-off connected.
•Make sure the drive shaft guards are in good condition and in place.
•Any damaged or inefficient guards must be replaced immediately.
•Never use the machine in an enclosed or poorly ventilated room (even if
the doors and windows are open) because the exhaust fumes are highly
toxic.
•Before disconnecting the machine from the motor-cultivator, make sure
they are standing still on firm, flat ground.

Use & Maintenance Instruction Manual TRX 50 / TRX 50 S
7.2.3 Electric version
•Maintenance, adjustment and cleaning operations (e.g. removing foreign
bodies from the hopper) must be done with the machine resting firmly on
the ground, switched off and disconnected from the power supply.
•The machine complies with the general principles of electrical safety.
This means that if any changes are made to the structure or
components, this will alter the characteristics of the system, which will no
longer comply with the safety requirements.
•Make sure the controls and cables are integral and in good condition.
•The electrical protection rating is IP54.
