WARNING
Risk of fire.
Keep fuel and other flammable sub-
stances away from the electrical com-
ponents.
Before beginning any maintenance op-
eration or any inspection of the motor-
cycle, stop the engine, remove the key
(1) from the ignition lock (2), wait until
the engine and the exhaust system have
cooled down and if possible lift the mo-
torcycle by means of the proper equip-
ment, on firm and flat ground.
Before proceeding, make sure that the
room in which you are working is prop-
erly ventilated.
Be careful to avoid hot parts of the en-
gine and exhaust system. They are hot
enough to cause serious burns.
Avoid the temptation to hold any part of
the motorcycle in your mouth. The
coatings and platings used are, in some
cases, toxic.
CAUTION
In general, reassembly is performed in
the reverse order of the disassembly in-
structions given here.
For some maintenance operations, es-
pecially those in which your hands are
likely to come in contact with coolant,
or engine oil, or gasoline, or brake fluid,
it is advisable to use thin disposable
gloves, such as those made of latex,
rubber or nitrile.
The routine maintenance operations de-
scribed in this manual can usually be per-
formed by the user. However, in some
cases, specific tools and technical exper-
tise may be required.
Do not hesitate to contact your Local
aprilia
Dealer who has all the latest factory infor-
mation and tools to properly service your
motorcycle.
Remember that many service operations, if
done improperly, can be very hazardous.
If you have any questions about your ability
to carry out the operations described here,
see your Local
aprilia
Dealer.
In all cases, personally carry out the “pre-
liminary checking operations” after any
maintenance, see p. 47 (PRELIMINARY
CHECKING OPERATIONS).
WARNING
Remember that tightening torque of all
fasteners on the wheels, brakes, axles,
suspension are extremely important to
ensure safety, and must be maintained
at the prescribed values.
Check the tightening torques of the fas-
teners regularly, and always use a
torque wrench when installing them.
Failure to adhere to this warning could
cause the loosening and subsequent
loss of critical fasteners, which could
cause a wheel to lock or cause other
handling problems with consequent
overturning, and the risk of serious inju-
ry or even death.
WARNING
Fasteners must be neither overtight-
ened or undertightened. If they are
overtightened, the threads may be dam-
aged and the fasteners will be de-
stroyed, whereas if they are undertight-
ened, they can vibrate and become lost.
Obviously, under these circumstances,
a serious accident with resultant seri-
ous injury or death could ensue.
