require contact with used oil. Used engine oil may
cause skin cancer if repeatedly left in contact with
the skin for prolonged periods. Although this is un-
likely unless you handle used oil on a daily basis, it is
advisable to thoroughly wash your hands with soap
and water after handling used oil.

In certain conditions, the ethylene glycol contained in the
engine coolant is flammable: its flame is invisible, but you
can be burned anyway.
a
WARNING
Avoid spilling the engine coolant on the exhaust sys-
tem or on the engine components. They may be hot
enough to cause the coolant to ignite and burn with-
out a visible flame.
The coolant (ethylene glycol) can cause skin irritation
and is poisonous if swallowed.
KEEP AWAY FROM CHILDREN.
Do not remove the radiator cap when the engine is
hot. The coolant is under pressure and may cause
burns.

The use of naked flames is forbidden for any type of

Before commencing any service or inspection opera-
tion on the vehicle, switch off the engine and remove
the key, wait until the engine and the exhaust system
have cooled down and, if possible, raise the vehicle
with the suitable equipment onto firm flat ground.
In order to avoid burns, be careful not to touch any
parts of engine or exhaust system which have not
cooled down completely.
The vehicle is constructed of inedible parts.
Do not bite, suck, chew or swallow any part of the ve-
hicle for any reason whatever.
If not expressly described, the reassembly of the
units is carried out by reversing the order of opera-
tions.
Handle fuel with the greatest caution.
Never use fuel as a solvent for cleaning the vehicle.
Disconnect the negative cable (–) from the battery
when electric welding.
When two or more persons are working together,
make sure that each is working in safe conditions.
BEFORE DISASSEMBLY
– Remove any dirt, mud, dust and foreign matters from
the vehicle before disassembling the components.
– Use, when necessary, the special tools designed for
this vehicle.
DISASSEMBLING THE COMPONENTS
– Before disconnecting the joints (pipes, cables, etc.),
mark the positions on all of them and mark them with
different distinguishing signs.
Each piece must be marked clearly, in order not to
have problems during installation.
– Clean and wash carefully any disassembled parts with
low inflammability detergents.
– Keep the parts that are used in pairs together, since
they have adapted to each other following the normal
wear. Some components must be used together or re-
placed completely.
– Keep away from heat sources.
