PREFACE
Important information regarding safety
Most accidents due to use, maintenance and repair of
vehicles are caused by failure to observe the most
elementary rules for safety and caution. An accident
can often be avoided if the potential hazards to which
one is exposed are known, and the required
precautions are taken. Those working on the vehicle
must take the utmost care, and must have suitable
technical skills and equipment for carrying out the
various operations correctly.
Improper use, lubrication, maintenance or repair of
this vehicle can lead to accidents and also death of
workers.
Use the vehicle or carry out maintenance or repairs on
it only after having completely read and understood all
of the instructions in this use and maintenance Manual.
The safety precautions and warnings are highlighted in
this Manual and on the vehicle by means of
informative stickers. Ignoring these warnings can
result in serious accidents, or even death for the
operator or other persons.
Magni Telescopic Handlers may not be able to
foresee all the possible circumstances which can
constitute a safety hazard. The warnings contained in
this Manual or applied on the vehicle may not be
considered as all-inclusive. In adopting procedures,
equipment or methods not expressly recommended,
it is the operator’s responsibility to make sure work
is carried out in accordance with the main safety
standards and in compliance with the law. Moreover,
it is necessary to ensure that the vehicle is not
rendered hazardous by accidental damage or
emergency maintenance carried out without
authorisation.
Information regarding this Manual
This Manual must be considered an integral part of the
vehicle, and must accompany it throughout its
working life from commissioning to final disposal. It
must therefore be kept safe in the spaces provided
inside the vehicle, or in such a place as to prevent
premature deterioration.
This Manual contains information regarding safety,
instructions for correct use of the vehicle and
recommendations for routine maintenance.
The information, technical specifications and
instructions contained in this Manual must be
considered as up to date on the date of its publication.
The Manufacturer reserves the right to make
modifications to the vehicles, their accessories,
calibration and other information disclosed at any
time without prior notification.
These modifications can influence the maintenance
and working of the vehicle. It is necessary to have the
latest and complete information before starting any
operation on the vehicle. Please contact your Magni
Dealer for the latest copy of this Manual.
If the vehicle is fitted with optional accessories, a use
and maintenance manual for the accessories will be
provided together with this Manual. The use and
maintenance manual of the accessories must be
considered as an integral part of the manual; therefore
it must be kept safe and consulted using the same
methods and with the same care.

avoided, can cause damage to property.
Yellow with safety alert symbol —used to indicate the presence
of a potentially dangerous situation which, if not avoided, can
cause minor or moderate injury.
Orange with safety alarm system —used to indicate the
presence of a potentially dangerous situation which, if not
avoided, can cause death or serious injury.
Red with safety alarm system —used to indicate the presence
of an imminently dangerous situation which, if not avoided, can
cause death or serious injury.

UNI EN ISO 7010:2012. To make it easy for the user, a
summary of the symbols used is given below with their
brief description:

naked flame
Reference regulatory framework
This Manual has been drafted in compliance with the
main reference standards:
-Machinery Directive 2006/42/EC;
-UNI 10653:2003 Technical documentation –
Quality of product technical documentation;
-UNI 10893:2000 Technical documentation of

SAFETY AND WARNINGS SECTION 9
SAFETY AND WARNINGS
SECTION
Symbols and safety labels
Several specific safety symbols are present on this
vehicle. This section shows the exact position of the
warning plates on the vehicle and the entity of the
hazard. Those using the vehicle must be fully aware of
the meaning of each safety symbol for rapid
identification and effective prevention of risks.
Make sure all the safety symbols are present and
clearly legible. Contact your dealer for missing labels,
or in case of labels present but not described in this
Manual. Clean illegible labels. Use a cloth, warm water
and neutral soap for cleaning. Do not use solvents,
petrol or abrasive chemical products for cleaning the
labels. These products will irremediably damage the
adhesive fixing the label to the vehicle.
Replace all missing or damaged safety labels. If a safety
label is applied on a part of the vehicle that is to be
replaced, make sure the spare part has a similar label.
Contact your dealer for assistance in case of irreparably
damaged labels, missing labels and labels present on the
vehicle but not described in this Manual.
Do not transport persons
The safety symbol is applied near the mud guards,
engine compartment and the compartment housing
the tanks.
It is forbidden to carry third persons while the vehicle
is in operation.
Do not touch
This safety symbol is present on the outside of the
engine compartment.
DANGER OF BURNS
The surfaces near the engine can get heated to
temperatures exceeding 100 °C.
Serious burns can be caused if the skin comes in
contact with these surfaces.
Do not touch the engine compartment and the parts
inside it without making sure they have cooled down.
Engine compartment
This safety symbol is applied on the engine bonnet
near the handle.
The safety symbols shown in the figure are applied
inside the engine compartment on the right.

10 SAFETY AND WARNINGS SECTION
There are several sources of risk inside the engine
compartment which can cause serious injury or even
death.
Do not approach or touch any part inside the engine
compartment without protective equipment and
adequate technical training.
The engine has tubing under high pressure. Liquid
leakage can penetrate the tissues causing even
serious injuries.
Do not disconnect the high pressure tubes. The liquid
trapped inside can leak out with considerable pressure
that could pierce the tissues, causing serious injury.
Do not touch the electric wiring or short circuit these.
The current in the electric wiring is high voltage and
can cause explosions or damage tissues if short
circuited.
There are scorching hot surfaces and flammable and
explosive materials inside the engine compartment.
Do not allow contact between the scorching hot
surfaces and flammable material.
Do not try to repair the high pressure tubing.
Carefully read the Use and Maintenance Manual
before starting the engine or carrying out
maintenance or repairs.
Radiator
This safety symbol is present on the upper part of the
radiator, inside the engine compartment.
Do not unscrew the radiator cap when the coolant is
still hot. The hot coolant is also pressurised, and
unscrewing the cap will cause ejection of boiling steam
jets with risk of even serious injuries.
Radiator fan
This safety symbol is present on the radiator surface
near the cooling fan.
Do not touch the radiator fan with the engine running.
The fast moving fan blades can cause severe tearing or
even cut the limbs.
Pressure of stabilisers on the ground
This safety symbol is applied on all four stabilisers.
Every vehicle model shows the corresponding values.
The values for each model can be seen in the
“Technical specifications” section in this manual.
Always make sure the ground is capable of
withstanding the load applied by the stabilisers.
Yielding of the ground can affect the stability of the
vehicle. If the stability is affected the result can be loss
of load, and in extreme cases, even tilting over of the
vehicle.
