•Use the specific tools designed for this scooter, as required.
REMOVAL OF COMPONENTS
•Do not loosen and/or tighten screws and nuts using pliers or other tools than the specially
designed wrench.
•Mark positions on all connection joints (pipes, cables etc.) before separating them, and
identify them with distinctive symbols.
•Each component needs to be clearly marked in order to be identified during reassembly.
•Clean and wash the dismantled components carefully using a low-flammability detergent.
SCARABEO 500 Characteristics
CHAR - 9

•Keep coupled parts together since they have "adjusted" to each other due to normal wear
and tear.
•Some components must be used together or replaced altogether.
•Keep away from heat sources.
REASSEMBLING COMPONENTS
CAUTION
NEVER REUSE A CIRCLIP; IF A CIRCLIP HAS BEEN REMOVED, IT MUST BE REPLACED WITH
A NEW ONE. WHEN INSTALLING A CIRCLIP, ENSURE THAT ITS ENDS ARE NOT STRETCHED
MORE THAN IS NECESSARY TO FIT IT ONTO THE SHAFT.
AFTER INSTALLING THE CIRCLIP, CHECK THAT IT IS FULLY AND CLEANLY INSTALLED IN ITS
SEAT.
DO NOT USED COMPRESSED AIR TO CLEAN BEARINGS.
NOTE
BEARINGS MUST BE ABLE TO ROTATE FREELY, WITHOUT JAMMING AND/OR NOISE, OTH-
ERWISE THEY NEED REPLACING.
•Use only ORIGINAL aprilia SPARE PARTS.
•Comply with lubricant and consumables usage guidelines.
•Lubricate parts (whenever possible) before reassembling them.
•When tightening nuts and screws, start from the ones with the largest section or from the
internal ones, moving diagonally. Tighten nuts and screws in successive steps before ap-
plying the tightening torque.
•Always replace self-locking nuts, washers, sealing rings, circlips, O-rings, split pins and
screws with new ones if their thread is damaged.
•When fitting bearings, make sure to lubricate them well.
•Check that each component is fitted correctly.
•After a repair or routine maintenance procedure, carry out pre-ride checks and test the ve-
hicle on private grounds or in an area with low traffic density.
•Clean all junction surfaces, oil guard rims and washers before refitting them. Smear a light
layer of lithium-based grease on the oil guard rims. Reassemble the oil guards and the
bearings with the brand or lot number facing outward (visible side).
ELECTRIC CONNECTORS
Electric connectors must be disconnected as described below as non-compliance with the procedure
so described causes irreparable damage to both the connector and the cable harness: Press the rele-
vant safety hooks, if any.
CAUTION
TO DISCONNECT THE TWO CONNECTORS, DO NOT PULL THE CABLES.
•Grip the two connectors and disconnect them by pulling them in opposite directions.
Characteristics SCARABEO 500
CHAR - 10

•In presence of dirt, rust, humidity etc., clean the connector's internal parts carefully, using a
pressurised air jet.
•Make sure that the cables are correctly linked to the connector's internal terminal ends.
NOTE
THE TWO CONNECTORS CONNECT ONLY FROM ONE SIDE; CONNECT THEM THE RIGHT WAY
ROUND.
•Then fit the two connectors making sure that they couple correctly (if the relevant hooks are
provided, you will hear them "click" into place).
TIGHTENING TORQUE
CAUTION
DO NOT FORGET THAT TIGHTENING TORQUES OF ALL FASTENING ELEMENTS ON WHEELS,
BRAKES, WHEEL SPINDLES AND OTHER SUSPENSION COMPONENTS PLAY A KEY ROLE IN
ENSURING THE VEHICLE'S SAFETY AND MUST COMPLY WITH SPECIFIED VALUES.
CHECK THE TIGHTENING TORQUES OF FASTENING PARTS ON A REGULAR BASIS AND AL-
WAYS USE A TORQUE WRENCH TO REASSEMBLE THESE COMPONENTS.
IF THESE RECOMMENDATIONS ARE NOT COMPLIED WITH, ONE OF THE COMPONENTS MAY
BECOME LOOSE AND EVEN DETACHED, THUS BLOCKING A WHEEL, OR OTHERWISE COM-
PROMISING THE VEHICLE'S MANOEUVRABILITY. THIS CAN LEAD TO FALLS, WITH THE RISK
OF SERIOUS INJURY OR DEATH.
BRAKE FLUID
CAUTION
DO NOT USE FLUIDS OTHER THAN THOSE PRESCRIBED AND DO NOT MIX DIFFERENT LIQ-
UIDS WHEN TOPPING UP IN ORDER NOT TO DAMAGE THE BRAKE SYSTEM.
DO NOT USE BRAKE FLUID TAKEN FROM OLD CONTAINERS OR FROM CONTAINERS THAT
HAVE BEEN OPEN FOR A PROLONGED TIME.
SUDDEN CHANGES IN THE PLAY OR ELASTIC RESISTANCE IN THE BRAKE LEVERS ARE DUE
TO FAULTS IN THE HYDRAULIC CIRCUIT.
MAKE ESPECIALLY SURE THAT BRAKE DISCS AND THE FRICTION MATERIAL ARE NOT
SMEARED OR GREASY, PARTICULARLY AFTER CARRYING OUT MAINTENANCE AND IN-
SPECTION OPERATIONS.
CHECK THAT BRAKE WIRES ARE NOT TWISTED OR WORN.
ENSURE THAT WATER OR DUST DO NOT INGRESS INADVERTENTLY INTO THE CIRCUIT.
IT IS ADVISABLE TO WEAR LATEX GLOVES WHEN SERVICING THE HYDRAULIC CIRCUIT.
DISC BRAKE
CAUTION
ANY OIL OR OTHER LIQUIDS ON A DISC WILL SOIL THE BRAKE PADS.
SOILED PADS MUST BE REMOVED AND REPLACED. A SOILED DISC OR A DISC WITH TRACES
OF OIL MUST BE CLEANED WITH A TOP QUALITY DEGREASING AGENT.
IF THE SCOOTER IS USED CLOSE TO WATER OR ON DUSTY OR UNSURFACED ROADS, OR
IF IT IS USED FOR SPORTS APPLICATION, HALVE THE SERVICE INTERVALS.
COOLANT
The engine is cooled by forced fluid circulation system. The coolant liquid is made up of 50% de-ionised
water and 50% glycol ethylene-based antifreeze solution with corrosion inhibitors. The product recom-
mended in the "recommended products table" is already mixed and ready to use.
SCARABEO 500 Characteristics
CHAR - 11

For the best functioning of the engine the temperature of the coolant fluid should register in the central
zone of the appropriate gauge. If the needle enters the red zone, stop the engine, allow it to cool, and
check the level of the fluid; if it is normal, contact an Official aprilia Dealer.
CAUTION
DO NOT USE YOUR VEHICLE IF THE COOLANT LEVEL IS BELOW THE MINIMUM LEVEL
MARKED "MIN".
CAUTION
COOLANT IS TOXIC IF INGESTED; CONTACT WITH EYES OR SKIN MAY CAUSE IRRITATION.
IN THE EVENT OF CONTACT WITH EYES OR SKIN, RINSE REPEATEDLY WITH ABUNDANT
WATER AND SEEK MEDICAL ADVICE. IF ACCIDENTALLY INGESTED, INDUCE VOMITING,
RINSE MOUTH AND THROAT WITH ABUNDANT WATER AND SEEK MEDICAL ADVICE IMME-
DIATELY.
CAUTION
DO NOT REMOVE THE EXPANSION TANK PLUG WHEN THE ENGINE IS HOT AS COOLANT IS
UNDER PRESSURE AND AT A HIGH TEMPERATURE. CONTACT WITH SKIN OR CLOTHES MAY
CAUSE SEVERE BURNS AND/OR INJURIES.
TYRES
CAUTION
CHANGING, REPAIR, MAINTENANCE AND BALANCING ARE IMPORTANT OPERATIONS THAT
ARE CARRIED OUT BY QUALIFIED PERSONNEL USING SUITABLE TOOLS.
THE NEW TYRES MAY BE COVERED WITH A THIN LAYER OF PROTECTIVE COATING THAT IS
SLIPPERY. DRIVE CAREFULLY FOR THE FIRST FEW KILOMETRES (MILES).
NEVER USE RUBBER TREATMENT AGENTS OF ANY KIND ON THE TYRES.
IN PARTICULAR ENSURE THAT THE TYRES DO NOT COME INTO CONTACT WITH LIQUID FUEL
THAT WOULD CAUSE A RAPID DETERIORATION OF THE RUBBER.
A TYRE THAT HAS BEEN IN CONTACT WITH OIL OR PETROL MUST BE REPLACED AND NOT
SIMPLY CLEANED.
DO NOT FIT TYRES WITH INNER TUBES ON RIMS FOR TUBELESS TYRES AND VICE VERSA.
