8 SECTION 00 - SAFETY RULES
PREVENTION OF FIRE OR EXPLOSIONS
The engine fuel can originate an explosion or a fire.
Never refuel when the engine is running.
Do not smoke during refuelling.
Take all the necessary safety measures when weld-
ing, grinding or when working near a naked flame.
Use a non-inflammable product for cleaning parts.
A spark or a flame can cause the electrolyte of the
battery to explode.
To prevent any risk of explosion, observe the follow-
ing instructions:
- when disconnecting the battery cables, always
disconnect the negative (-) cable first;
- to reconnect the battery cables, always connect
the negative (-) cable last;
- never short-circuit the battery clamps with metal
objects;
- do not weld, grind or smoke near a battery.
The engine exhaust may produce sparks.
Before using the machine in an area which may con-
tain inflammable vapours, ensure that there is good
ventilation.

SECTION 00 - SAFETY RULES 9
PREVENTION OF BURNS
The battery electrolyte generates severe burns.
The battery contains sulphuric acid.
Avoid any contact with the skin, eyes or clothing.
Antidote:
- EXTERNAL: rinse well with water, removing any
soiled clothing.
- INTERNAL: avoid vomiting. Drink water to rinse
your mouth. Consult a doctor.
- EYES: rinse thoroughly with water for 15 minutes
and get prompt medical attention.
When the electrolyte of a battery is frozen, it can
explode if you attempt to charge the battery or if you
try to start the engine using a booster battery.
Always keep the battery charged to prevent the elec-
trolyte freezing.
Batteries generate explosive gases.
Keep all flames, sparks and cigarettes away.
Provide good ventilation when changing a battery or
using a battery in an enclosed space.
Always protect your eyes when working near a bat-
tery.
Never touch the battery terminals with your hands.
This can induce a state of electrolysis and impair the
main organs of the body.
Hot coolant could spray out if the radiator cap is
removed while the system is still hot.
To remove the cap: allow the system to cool down,
turn the cap to the first notch and wait until there is
no more pressure.
Then remove the cap.

PRECAUTIONS FOR WASTE DISPOSAL
Improperly disposing of waste can threaten the envi-
ronment.
Each country has its own Regulations on this sub-
ject. It is therefore advisable to prepare suitable con-
tainers to collect and store momentarily all solid and
fluid materials that must not be scattered in the envi-
ronment to avoid pollution.
At preset intervals these products will be delivered
to disposal stations legally recognized and present
in this Country.
Here below is a list of the products in the machine
which require disposal:
- hydraulic oil;
- brake system oil;
- coolant mixture, condensation residue and pure
anti-freeze;
- diesel oil;
- oil and diesel oil filter elements;
- engine and air conditioning air filter elements;
-battery.
Also polluting rags, paper, sawdust and gloves must
be disposed in compliance with the same proce-
dures.
Do not use food or beverage containers that may
mislead someone into drinking from them.
Do not pour waste onto the ground, down a drain, or
into any water source.
Air conditioning coolant escaping into the air can
damage the Earth’s atmosphere.
Government regulations may require a certified air
conditioning service centre to recover and recycle
used air conditioning coolant.
Obtain information on the proper way to recycle or
dispose of waste from your local environmental or
recycling centre, or from your Dealer.
