The non-performance of these checking
operations can cause severe personal
injuries or damages to the vehicle.
For the tightening of nuts and screws
whose driving torque is not indicated in
this Use and Maintenance Manual, con-
tact an aprilia Official Dealer. The tight-
ening of a component at the wrong driv-
ing torque may be dangerous for your and
other people’s safety.
Do not hesitate to consult your aprilia
Official Dealer in case there is something
you do not understand about the func-
tioning of some controls or in case you
suspect or discover some irregularities.
It does not take long to carry out a check-
up and this operation ensures you much
more safety.

Make sure there are no leaks or occlusions in the circuit.

tween the “MIN” and “MAX” markings.
