INTRODUCTION
•ThisWorkshop Manual describesthe main electrical/mechanical checks,theessential checksand the assemblyof
components supplied disassembled in order to deliver a brand new vehicle (the sequence of operations is not
binding).
•It is essential to follow the instructions with great care.Work carried out carelessly or, worse still, work that has not
been accomplished, can cause injuries and damage or, in the less serious cases, complaints.
NOTE These manuals provide the necessary information and instructions for routine maintenance and serv-
icing.
Some information has been given to us by the engine manufacturers.We therefore decline all respon-
sibility for any error, omission or misrepresentation.
MALAGUTI reserves the right to make any changes and modifications hereto it deems necessary
without prior notice.
MANUAL UPDATES
• The updates will be sent by us (in a reasonable time).Every CD-Rom you receive will supersede the one already in
yourpossession.
•The table of contents will be duly updated in the event that new pages are inserted, which render the consultation
of the manual difficult.
•IMPORTANT! TheWorkshop Manuals are to be considered as essential tools to be properly kept up-to-date so as
to maintain their validity over time.

GENERAL WORK PROCEDURES
• Theadvice,recommendations and warnings givenhereafter are aimed atensuring maximumwork safetyas 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
tendstoopen thus risking damaging the screwhead 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 forthe customer, onwhichto takea noteof
allthe workperformed andwrite memos relatingto any
future checks that may be required.
RECOMMENDATIONS
•Before carrying outany workonthe vehiclewaitforall
the parts to cool down completely.
• Foroperationsrequiringtwomechanics,makesurethat
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”,whichmustbereached progressively
by steps.
• Loosenandtighten aluminium alloyparts (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.

AND CONTROL FUNCTION
FRAME AND RUNNING GEAR
DIGITAL INSTRUMENT PANEL
This new digital instrument board offers several additional functions- compared to traditional ones - through which
driver may optimally manage his/her vehicle.The panel is equipped with a warning light signalling shortage of coolant
or improper connection with the radiator’s thermostat.This light comes on automatically. To select the functions shown
on the display, press the MODE button located at the front of the left hand control (see page 18).
Availablefunctions are:
0-40 (acceleration from 0 to 40 km/h),
TIME (clock),
LAP (chronometer),
AVE (average speed),
TD (partial distance),
TOD (total distance),
BAR GRAPH with three functions:battery charge level, coolant temperature, number of engine revolutions.
For the English version,the display will be in miles,not km.The digital instrument board only works
if the battery is connected.If the battery is flat,replace it immediately.When the battery is replaced or
the fuse is removed,power is disconnected;any settings memorised on the instrument panel,except
the total distance travelled,will be reset.
Replace the flat battery with a new one;if the problem remains, call an Authorised MALAGUTI Service Centre.
Do not use your vehicle when no function appears on the display or when functions appear partially,
since the instrument board is not in the condition to provide sufficient information about your vehi-
cle.
SETTING
Power up the instrument board by connecting the battery to the vehicle’s cables.Put the key in the ignition switch and
turn it to.The names of stored flywheels appear successively on the display:before selecting your type, check the type
of flywheel installedon your vehicle on the anti-tampering label under the seat (seepage 33).When the code of your
modelappearson the display, press the MODE button, tomake your selection.If you choose the wrong model, you will
be shown improper information (speed, km, etc.).If you choose the wrong model, turn the panel off, wait for about two
minutes and repeat the above operations in the correct manner.
These operations must be repeated every time the battery is disconnected.
MILES OR KILOMETRES SELECTION
If you are driving in countries with different measurement systems, you can change the unit of measurement of speed
(instant and average) and distance from kilometres to miles and vice versa. To make your selection, first of all the
vehicle must be stationary.Now hold the MODE button down for 5” after selecting the TOD function.When „Mph“ and
„Km/h“ appear, give the MODE button short presses until the unit of measurement starts flashing. Hold the MODE
button down to save your selection.The instrument board will return to its normal display mode.Any stored information
(with the exception ofTOD) will be reset.
Using a unit of measurement that differs from the one used in the country where you are driving may
lead to improper calculations,especially concerning the vehicle’s speed.Consequences include ex-
posure of the driver and others to dangers, as well as fines.

STARTING
Put the key into the ignition switch and turn it to .A check for all operations will automatically appear for 3 seconds,
after which the last function used before turning off the vehicle will appear.
The check is automatically performed every time the key is turned to. If the check is not displayed,
contact an authorised MALAGUTI Service Centre.
CHOOSING FUNCTIONS
Functions are divided into menus and sub-menus (bar
graph), which make the display easier to understand.
To select a function, press the MODE button, as shown in
the diagram.
The diagram shows you for how long the MODE button
should be held down (near the arrows).
To help you identify the functions and acquire information
about their characteristics, a description is provided here
below, indicating the functions in the order in which they
appear on the display
Menu functions can be seen from every sub-
menu.
MAIN MENU FUNCTIONS
A) TOD FUNCTION
This indicates the total distance travelled; this value is never reset and remains even
after the vehicle is turned off (the total distance travelled will be stored for 10 years
running from the last time the vehicle was used).
