1.1 WARNINGS
Carbon monoxide
The exhaust fumes contain carbon monoxide, a poisonous gas that can cause death. Therefore, for certain operations,
make sure you are in an open space, or in a suitable and well-ventilated room, never in enclosed spaces. If operating in
enclosed spaces, use an evacuation system for the exhaust fumes.
Fuel
The fuel used is extremely flammable and can become explosive under certain conditions. Refuelling and maintenance
operations must be carried out in a ventilated area and with the vehicle switched off. Do not smoke during refuelling and
near fuel vapours; avoid contact with open flames, sparks and any other source that could cause ignition or explosion.
Do not disperse in the environment and keep away from children.
Hot components
The engine and certain components become very hot and remain hot for a while even when the engine is off. Before
carrying out any operation near the engine or exhaust system, wear insulating gloves or wait for their cooling.
Used engine and gearbox oil
Used engine and gearbox oil is harmful to health, whether it is inhaled or swallowed. It is also irritating and can cause
serious consequences if it comes into contact with the skin.
Spreading and dispersion into the environment is prohibited.
If swallowed, do not induce vomiting, but go urgently to a first aid centre, indicating the cause and how the accident
occurred.
In case of contact with the skin, immediately wash the affected part with soap and water, repeating the operation until
the affected part is free from residues.
In case of contact with eyes and ears, immediately rinse the affected parts with plenty of water and urgently go to a first
aid center, indicating the cause and how the accident occurred.
In case of contact with clothing, undress and wash thoroughly with soap and water. Change the dirty cloths which must
be specifically washes as soon as possible.
Always use gloves suitable to protect your hands during the maintenance operations.
Keep out of the reach of children.
Used engine and gearbox oil must be collected in a sealed container, and delivered to the nearest service station or at a
waste oil collection centre where you will find personnel authorized to dispose of it.
Brakes
Brake fluid may damage the vehicle painted, plastic or rubber surfaces. Protect these components with a clean rag when
performing certain operations.
Always wear protective glasses and in case of accidental contact of the brake fluid with eyes, rinse immediately with
plenty of clean, fresh water and consult a doctor immediately. Keep out of the reach of children.
Clean the brake pads in a ventilated environment, directing the compressed air jet so as not to inhale the dust produced
by the wear of the friction material. Although the latter does not contain asbestos, inhaling dust is however harmful.
Electrolyte and hydrogen gas from the battery
The electrolyte of the battery is toxic and caustic. In contact with skin it can cause burns, as it contains sulphuric acid.
Wear gloves and protective clothing.
If the electrolyte liquid comes into contact with the skin, wash it thoroughly with fresh water.
Protect your eyes, as battery fluid can cause blindness. If it comes into contact with the eyes, wash thoroughly with
water for fifteen minutes and promptly contact an eye specialist.

The battery emits explosive gases, it is advisable to keep away flames, sparks and any other source of heat. Provide
adequate ventilation when servicing or recharging the battery.
Keep out of the reach of children.
The battery fluid is corrosive. Do not pour it or spread it, especially on plastic parts.
Provide for regular disposal.
Coolant
Under certain conditions, the ethylene glycol present in the engine coolant is combustible and its flame is not visible. If
ethylene glycol is ignited, its flame is not visible but it is able to cause serious burns.
Avoid pouring engine coolant to the exhaust system or on engine parts. These parts may be hot enough to ignite the
liquid which then burns without visible flames. Coolant (ethylene glycol) can cause skin irritation and is poisonous if
swallowed. Keep out of the reach of children. Do not remove the radiator cap when the engine is still hot. Coolant is
under pressure and may cause burns.
Keep hands and clothes away from the cooling fan as it starts automatically.
Precautions and general warnings
The clothing of the operator performing the repair operations must be adequate to avoid the risk of injury when working
on moving parts (for example, too wide clothes that can get caught).
Do not wear personal items (e.g. rings, wristwatches, etc.) while performing repairs on the vehicle, and in particular on
the electrical system.
Keep the work area tidy, to avoid that elements left on the ground interfere with the repair operations.
Clean the floors of the working areas from oil, grease or other residual fluids, to avoid slipping.
Perform compression or decompression operations on the springs, using only suitable tools to prevent the operations
from causing damage to the operator.
Avoid inhalation of vapours from cleaning fluids: they can be highly toxic. Make sure the work area is properly ventilated.
Use suitable cleaning products for each operation, making sure that they are approved.
Wear eye protection when using electrical tools such as drills, grinders or milling machines.
