WARNINGS
•
Before
carrying out any operation on the vehicle
,
wait for all parts to
cool
down.
• For operations requiring two mechanics, make sure that the various steps to be performed
by each of them are clearly defined and coordinated beforehand.
• Make sure that each component has been properly fitted before proceeding with the next
one.
• Lubricate all parts (where applicable) before reinstalling them.
• Gaskets, O-rings, circlips and split pins
must be replaced
at every refitting.
• The torque settings specified in the manuals refer to the “
final torque
”, which must be
attained progressively by steps.
• Loosen and tighten aluminium alloy parts (covers) only after the
engine has fully cooled
down
.
• Only use screwdrivers with sizes suitable to the screws to be loosened or tightened.
• Work in a comfortable position and ensure that the vehicle is stable.
• Never use a screwdriver as a lever or chisel.
• Never use pincers to loosen or tighten screws or nuts because, in addition to
not providing a sufficient clamping force, they may also damage the screw head
or nut hexagon.
• Never tap the wrench with a hammer or other similar tools to loosen or tig-
hten screws and nuts (F-2).
• Never attempt to increase the lever arm by fitting a tube into the wrench (F-
