To drive the vehicle it is necessary to be in
possession of all the requirements pre­scribed by law (driving licence, minimum
age, psychophysical ability, insurance,
state taxes, vehicle registration, number
plate, etc.).

Gradually get to know the vehicle by driv­ing it first in areas with low traffic and/or pri­vate areas.

use and maintenance Scarabeo 50 - Scarabeo 100

The use of medicins, alcohol and drugs or
psychotropic substances notably increases
the risk of accidents.

Be sure that you are in good psychophysi­cal conditions and fit for driving and pay
particular attention to physical weariness
and drowsiness.

Most road accidents are caused by the
driver’s lack of experience.

NEVER lend the vehicle to beginners and,
in any case, make sure that the driver has
all the requirements for driving.

Rigorously observe all road signs and na­tional and local road regulations.

Avoid abrupt movements that can be dan­gerous for yourself and other people (for
example: rearing up on the back wheel,
speeding, etc.), and give due consideration
to the road surface, visibility and other driv­ing conditions.

Avoid obstacles that could damage the ve­hicle or make you lose control.

Avoid riding in the slipstream created by
preceding vehicles in order to increase
your speed.

Always keep both hands on the handlebars
and both feet on the footboard (or on the
footrests), in the correct driving posture.

Avoid standing up or stretching your limbs
while driving.

The driver should pay attention and avoid
distractions caused by people, things and
movements (never smoke, eat, drink, read,
etc.) while driving.

use and maintenance Scarabeo 50 - Scarabeo 100

Use only the vehicle’s specific fuels and lu­bricants indicated in the "LUBRICANT
CHART"; check all oil, fuel and coolant lev­els regularly.

If the vehicle has been involved in an acci­dent, make sure that no damage has oc­curred to the control levers, pipes, wires,
braking system and vital parts.

If necessary, have the vehicle inspected by
an aprilia Official Dealer, who should care­fully check the frame, handlebars, suspen­sions, safety parts and all the devices that
you cannot check by yourself.

Always remember to report any malfunc­tion to the technicians to help them in their
work.

Never use the vehicle when the amount of
damage it has suffered endangers your
safety.

Never change the position, inclination or
colour of: number plate, direction indica­tors, lights and horns.

Any modification of the vehicle will result in
the invalidity of the guarantee.

For only vehicles up to 50 cm3 included

Any modification of the engine or of other
members which is aimed at increasing the
speed or the power of the vehicle is prohib­ited by the law; in fact, any modification re­sulting in an increase of the maximum
speed or of the engine displacement would
change the scooter into a motorcycle,

ONLY ORIGINALS

which implies the following obligations for
the owner:

– new homologation;
– new registration;
– appropriate driving license.

Further, said modifications cause the loss
of the insurance cover, since insurance
policies expressly prohibit to make techni­cal changes aimed at increasing the vehi­cle performance levels.
For the reasons stated above, the failure to
comply with the tampering prohibition is
punished by law with appropriate sanctions
(including the confiscation of the vehicle),
which, according to the case, can be com­bined with the sanctions provided for not
using the crash helmet and/or the number
plate, for the violation of fiscal obligations
(ownership tax) and with penal sanctions
provided for using the vehicle without driv­ing license.

For only vehicles over 50 cm

Any modification of the vehicle and/or the
removal of original components can com­promise vehicle performance levels and
safety or even make it illegal.

We recommend respecting all regulations
and national and local provisions regarding
the equipment of the vehicle.

In particular, avoid all modifications that in­crease the vehicle’s performance levels or
alter its original characteristics.

Never race with other vehicles.
Avoid off-road driving.

Before starting, always wear a correctly
fastened crash helmet. Make sure that it is
homologated, in good shape, of the right
size and that the visor is clean.

Wear protective clothing, preferably in light
and/or reflecting colours.
In this way you will make yourself more vis­ible to the other drivers, thus notably re­ducing the risk of being knocked down, and
you will be more protected in case of fall.

This clothing should be very tight-fitting
and fastened at the wrists and ankles.
Strings, belts and ties should not be hang­ing loose; prevent these and other objects
from interfering with driving by getting en­tangled with moving parts or driving mech­anisms.

use and maintenance Scarabeo 50 - Scarabeo 100

Do not keep objects that can be dangerous
in case of fall, for example pointed objects
like keys, pens, glass vials etc. in your
pockets (the same recommendations also
apply to passengers).

!##%33/2)%3

The owner of the vehicle is responsible for
the choice, installation and use of any ac­cessory.

Avoid installing accessories that cover
horns or lights or that could impair their
functions, limit the suspension stroke and
the steering angle, hamper the operation of
the controls and reduce the distance from
the ground and the angle of inclination in
turns.

Avoid using accessories that hamper ac­cess to the controls, since this can prolong
reaction times during an emergency.

Big fairings and windshields installed on
the vehicle may produce aerodynamic forc­es that affect the stability of the vehicle, es­pecially when riding at high speed.

Make sure that the equipment is well fas­tened to the vehicle and not dangerous
during driving. Do not install electrical de­vices and do not modify those already ex­isting to avoid electrical overloads, be­cause the vehicle could suddenly stop or
there could be a dangerous current short­age in the horn and in the lights.
aprilia recommends the use of “aprilia
genuine accessories”.

,/!$

Be careful and moderate when loading
your luggage. Keep any luggage loaded as
close as possible to the center of gravity of
the vehicle and distribute the load uniform­ly on both sides, in order to reduce imbal­ance to the minimum. Furthermore, make
sure that the load is firmly secured to the
vehicle, especially during long trips.

KG!

Avoid hanging bulky, heavy and/or danger­ous objects on the handlebars, mudguards
and forks: the vehicle might respond more
slowly in turns and its manoeuvrability
could be unavoidably impaired.

Do not place bags that are too bulky on the
vehicle sides, because they could hit peo­ple or obstacles, making you lose control of
the vehicle.

Do not carry any bag if it is not tightly se­cured to the vehicle.

Do not carry bags which protrude too much
from the luggage-rack or which cover the
lights, horn or indicators.

Do not carry animals or children on the
glove compartment or on the luggage­rack.

Do not exceed the maximum load allowed
for each side-bag.

When the vehicle is overloaded, its stability
and its manoeuvrability can be compro­mised.

Do not use the vehicle if the braking
system leaks fluid.

CHECKING

To check the brake fluid level, proceed as
follows:

◆

Position the vehicle on the centre stand
on firm and level ground.

◆

Rotate the handlebar, so that the fluid
contained in the brake reservoir is paral­lel to the “MIN” mark stamped on the
glass gauge (2).

MIN = minimum level.

Make sure that the fluid contained in the
reservoir exceeds the “MIN” mark
stamped on the glass gauge (2).

If the fluid does not reach at least the “MIN”
mark:

aCAUTION

When the disc pads wear out, the level
of the fluid decreases progressively to
compensate for their wear.

This vehicle is provided with tyres with in­ner tube.

aWARNING

Periodically check the tyre inflation
pressure at room temperature, see p. 83
(TECHNICAL DATA).

If the tyres are hot, the measurement is
not correct.
Carry out the measurement especially
before and after long rides.

use and maintenance Scarabeo 50 - Scarabeo 100

32

aWARNING

If the inflation pressure is too high, the
ground unevenness cannot be damp­ened and is therefore transmitted to the
handlebar, thus compromising the driv­ing comfort and reducing the road hold­ing during turns.

If, on the contrary, the inflation pressure
is too low, the tyre sides (1) are under
greater stress and the tyre itself may
slip on the rim or it may become loose,
with consequent loss of control of the
vehicle.

In case of sudden braking the tyres
could even come off the rims.
Further, the vehicle could skid while
turning.

aWARNING

Check the surface and the wear of the
tyres, since tyres in bad conditions can
impair both the grip and the controlla­bility of the vehicle.

Some types of tyres homologated for
this vehicle are provided with wear indi­cators.
There are several kinds of wear indica­tors.
For more information on how to check
the wear, contact your Dealer.
Visually check if the tyres are worn and
in this case have them changed.

Change the tyre when it is worn out or
in case of puncture on the tread side, if
the puncture is larger than 5 mm.

After repairing a tyre, have the wheels
balanced.

aWARNING

The tyres must be replaced with other
tyres of the type and model recom­mended by the manufacturer, see p. 83
(TECHNICAL DATA); the use of tyres
different from those prescribed may ad­versely affect the manoeuvrability of the
vehicle.

Do not install tyres with air tube on rims
for tubeless tyres and viceversa.

Make sure that the inflation valves (2)
always have their sealing caps on, to
prevent the tyres from suddenly going
flat.

Change, repair, maintenance and bal­ancing operations are very important
and therefore they must be performed
by qualified technicians with appropri­ate tools.

aWARNING

For this reason, it is advisable to have
the above mentioned operations carried
out by an APRILIA Official Dealer or by a
qualified tyre repairer.
If the tyres are new, they may still be
covered with a slippery film: drive care­fully for the first miles. Do not oil the
tyres with unsuitable fluids. If the tyres
are old, even if not completely worn out,
they may become hard and may not en­sure good road holding.
In this case, replace them.

aWARNING

Avoid parking the vehicle catalytic ver­sion near dry brush wood or in places
easily accessible to children, as the cat­alytic silencer becomes extremely hot
during use; be very careful and avoid
any kind of contact before it has com­pletely cooled down.

The catalytic vehicle is fitted with a silencer
with metal catalytic converter of the “plati­num-rhodium bivalent” type.

This device provides for the oxidation of
the CO (carbon monoxide) and of the HC
(unburned hydrocarbons) contained in the
exhaust gases, changing them into carbon
dioxide and steam, respectively.

Due to the catalytic reaction, the high tem­perature reached by the exhaust gases
makes for the burning of the oil particles,
thus keeping the silencer clean and elimi­nating the exhaust fumes.

To have the catalytic converter function
correctly and for long and to reduce possi­ble problems regarding the soiling of the
thermal unit and of the exhaust, it is neces­sary to avoid covering long distances with
the engine running at constantly low rpm.

It is sufficient to alternate these periods
with periods in which the engine runs at rel­atively high rpm, even if only for a few sec­onds, but rather frequently.

What has been stated above assumes par­ticular importance for the cold starting of
the engine: in this case, in order to reach a
rpm regime sufficient to enable the “prim­ing” of the catalytic reaction, just make
sure that the temperature of the thermal
unit has reached at least 50°C, which gen­erally occurs a few seconds after starting
the engine.

aCAUTION

Do not use leaded petrol, since it caus­es the destruction of the catalytic con­verter.

If you have to brake, close the throttle
and put on both brakes in order to ob­tain uniform deceleration, properly ex­erting pressure on the braking parts.
By putting on the front brake only or the
rear brake only, you reduce the braking
force considerably, thus running the
risk of locking one wheel and conse­quently losing grip.

If you stop uphill, decelerate completely
and use the brakes only to keep the ve­hicle steady.
The use of the engine to keep the vehi­cle at a halt may cause the overheating
of the speed variator.

aWARNING

Before beginning to turn, slow down or
brake driving at moderate and constant
speed or accelerating slightly; avoid
braking at the last moment: it would be
very easy to skid.

If the brakes are operated continuously
on downhill stretches, the friction mate­rial may overheat, thus reducing the
braking efficiency.

Exploit the engine compression by
putting on both brakes intermittently.
Never drive downhill with the engine
off!

aWARNING

When visibility is insufficient, switch on
the low beam even during the day, in or­der to make your vehicle more visible.
In case of wet ground or scarce wheel
grip (snow, ice, mud, etc.), drive slowly,
avoiding sudden brakings or manoeu­vres that could make you lose grip and
fall down.

aWARNING

Pay the utmost attention to any obsta­cle or variation of the road surface.
Uneven roads, rails, manhole covers,
indications painted on the road surface,
building site metal plates become rather
slippery by rain. For this reason all
these obstacles have to be carefully
avoided, driving smoothly and bending
the vehicle as little as possible.

aWARNING

Always use the direction indicators in
time when you intend to change lane or
direction, avoiding sharp and danger­ous movements.
Switch off the direction indicators as
soon as you have changed direction.

Be extremely careful when you overtake
other vehicles or are overtaken.
In case of rain, the water cloud created
by big vehicles reduces visibility; the
air shift may make you lose control of
the vehicle.

#,%!.).'

Clean the vehicle frequently if it used in
particular areas or conditions, such as:

◆

Polluted areas (cities and industrial are­as).

◆

Areas characterized by an high percent­age of salinity and humidity (sea areas,
hot and humid climates).

◆

Particular conditions (use of salt and
anti-ice chemical products on the roads
during the winter).

◆

Avoid leaving deposits of industrial and
polluting powders, tar spots, dead in­sects, bird droppings, etc. on the body.

◆

Avoid parking the vehicle under trees,
since in some seasons residues, resins,
fruits or leaves fall down, which contain
substances that may damage the paint.

aWARNING

After the vehicle has been washed, its
braking functions could be temporarily
impaired because of the presence of
water on the grip surfaces. Calculate
long braking distances to avoid acci­dents. Brake repeatedly to restore nor­mal conditions.

Carry out the preliminary checking op­erations, see p. 35 (PRELIMINARY
CHECKING OPERATIONS).

To remove dirt and mud from the painted
surfaces use a low- pressure water jet,
carefully wet the dirty parts, remove mud
and filth with a soft car sponge impregnat­ed with a lot of water and shampoo (2 – 4%
parts of shampoo in water).
Then rinse with plenty of water and dry with
chamois leather.
To clean the outer parts of the engine use
a degreaser, brushes and wipers.

aCAUTION

To clean the lights, use a sponge soaked
with water and a neutral detergent, rub­bing the surfaces delicately and rinsing
frequently with plenty of water.
Polish with silicone wax only after hav­ing carefully washed the vehicle.

Do not use polishing pastes on matt
paints.

Do not wash the vehicle under the sun,
especially during the summer, when the
body is still warm, since if the shampoo
dries before being rinsed away, it can
damage the paint.

Do not use liquids at a temperature ex­ceeding 40°C to clean the plastic com­ponents of the vehicle.

aCAUTION

Do not direct high-pressure water or air
jets or steam jets on to the following
components: wheel hubs, controls on
the right and left side of the handlebar,
bearings, brake pumps, instruments
and indicators, silencer exhaust,
glove/tool kit compartment, ignition
switch/steering lock, fuel cap, lights
and electric connections.

Do not use alcohol, petrol or solvents to
clean the rubber and plastic parts and
the saddle: use only water and mild
soap.

aWARNING

Do not apply protection waxes onto the
saddle, in order not to make it too slip­pery.

After a long period of inactivity of the vehi­cle some precautions are necessary to
avoid any problem.

Further, it is important to carry out the nec­essary repairs and a general check up be­fore the period of inactivity, since you could
forget to carry them out later.

Proceed as follows:

◆

Empty the fuel tank and the carburettor,
see p. 80 (DRAINING THE FUEL
TANK).

◆

Extract the spark plug, see p. 69
(SPARK PLUG) and pour a teaspoon (5­10 cm#) of two-stroke engine oil into the
cylinder,

NOTE Put a clean cloth on the cylinder,

near the spark plug seat, in order to protect
it from oil sprays.

◆

Move the ignition switch to position “n”,
press the start push button “
seconds, to distribute the oil evenly on
the cylinder surfaces.

◆

Remove the cloth.

◆

Put back the spark plug.

◆

Remove the battery, see p. 72 (REMOV­ING THE BATTERY).

◆

Wash and dry the vehicle, see p.81
(CLEANING).

◆

Polish the painted surfaces with wax.

r” for a few

◆

Inflate the tyres, see p. 32 (TYRES).

◆

By means of a suitable support, position
the vehicle so that both tyres are raised
from the ground.

◆

Place the vehicle in an unheated, not-hu­mid room, away from sunlight, with mini­mum temperature variations.

◆

Position and tie a plastic bag on the final
pipe of the exhaust silencer, in order to
prevent moisture from getting into it.

◆

Cover the vehicle avoiding the use of
plastic or waterproof materials.

AFTER A PERIOD OF INACTIVITY

◆

Uncover and clean the vehicle, see p. 81
(CLEANING).

◆

Check the charge of the battery, see
p. 73 (RECHARGING THE BATTERY)
and install it, see p. 73 (INSTALLING
THE BATTERY).

◆

Make sure that the fuel drain screw is
thoroughly screwed (breather pipe clos­ing index), see p. 80 (DRAINING THE
FUEL TANK).

◆

Refuel, see p. 26 (FUEL).

◆

Carry out the preliminary checking oper­ations, see p. 35 (PRELIMINARY
CHECKING OPERATIONS).
