GENERAL WORK PROCEDURES
• The advice, recommendations and warnings given hereafter are aimed at ensuring maximum work safety as well
as at considerably reducing the risk of accidents, personal injury, equipment damage and idle times. We therefore
recommend observing such advice, recommendations and warnings scrupulously.
SUGGESTIONS
• Only use top quality tools and equipment.
• Only use equipment conforming to EU Directives for lifting the vehicle.
• During all operations keep tools close at hand, ideally in accordance with a predetermined sequence of use, and
anyway never leave tools on the vehicle or in concealed or hard to reach positions.
• Always keep the work area clean and tidy.
• When tightening screws or nuts, start with the larger diameter or inner fasteners, and tighten them in a “crosswise
pattern” in successive “torquing steps”.
• Preferably use open-end wrenches and tighten by exerting “pulling force” rather than “pushing force”.
• Adjustable wrenches should only be used in case of
emergency, i.e. when a properly sized wrench is not
available. During the torquing stage the movable jaw
tends to open thus risking damaging the screw head or
achieving unreliable tightening torque values. In any
case, when using an adjustable wrench, take care to
proceed as shown in the figure.
• Except in the case of occasional services, prepare a
work sheet for the customer, on which to take a note of
all the work performed and write memos relating to any
future checks that may be required.
RECOMMENDATIONS
• Before carrying out any work on the vehicle wait for all
the parts to cool down completely.
• 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 fit-
ted before proceeding with the next one.
• Lubricate all parts (where applicable) before reinstall-
ing them.
• Gaskets, oil seals, snap rings and cotters must be re-
newed at every refitting.
• The torque settings specified in the manuals refer to
the “final torque”, which must be reached progressive-
ly by steps.
• Loosen and tighten aluminium alloy parts (covers) only
after the engine has cooled down fully.
• Only use screwdrivers of suitable sizes in relation to
the screws to be loosened or tightened.
• Work in a comfortable position and ensure that the ve-
hicle is stable.
• Never use a screwdriver as a lever or chisel.
• Never use pliers 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 hex.
• Never tap wrenches with a hammer (or other similar tools) to loosen or tighten screws and nuts.
• Never attempt to increase leverage by attaching tubes, etc. to wrenches.
