Automatic transmission
To ensure simple, pleasurable riding, the vehicle is equipped with automatic transmission with regulator and centrifugal clutch. The system is designed to give the best
possible performance in terms of both acceleration and consumption, on level ground
and uphill, thanks to the adjustments made to engine speed and transmitted torque.
If you have to stop on an uphill slope (traffic lights, traffic jam, etc.) only use the brake
to keep the vehicle still, leaving the motor running at idling speed. Using the motor to
keep the vehicle still can cause the clutch to overheat. This problem is due to the
friction of the clutch parts on the clutch bell. It is therefore recommended to avoid
conditions of prolonged clutch slippage leading to clutch overheating (for example, as
well as the situation described above, riding uphill fully laden on steep slopes or starting off on slopes greater than 25%, etc.):
1. Do not continue riding in such conditions.
2 Use
2. Let the clutch cool down with the motor at idling speed for a few minutes
24
WARNING
SOME SIMPLE TIPS ARE PROVIDED BELOW WHICH WILL ENABLE YOU TO
USE YOUR VEHICLE ON A DAILY BASIS MORE EASILY AND SAFELY.
<
Your ability and your knowledge of the vehicle form the basis of safe riding. We recommend trying out the vehicle in traffic-free zones to get to know your vehicle
completely.
ALWAYS DRIVE WITHIN YOUR LIMITS
1. Before riding off, remember to put on your helmet and fasten it correctly.
2. Reduce speed and ride cautiously on uneven roads.
02_08
3. Remember that after riding on a long stretch of wet road without using the brakes,
the braking effect is initially lower. Under these conditions, it is a good idea to operate
the brakes from time to time.
4. Do not brake hard on a wet surface, on dirt tracks or on any slippery road surface.
5. If you have to brake, use both brakes in order to divide the braking action between
both wheels.
6. Avoid starting off by mounting the vehicle while it is still resting on its stand. In any
case, the rear wheel should not be turning when it comes into contact with the ground,
in order to avoid abrupt departures.
7. If the vehicle is used on roads covered with sand, mud, snow mixed with salt, etc.,
clean the brake disc frequently with mild detergent in order to prevent abrasive substances from building up within the holes, which can result in early wear of the brake
pads.
25
2 Use
Safe driving (02_08)
8. Any elaboration that modifies the vehicle's performances, such as tampering with
original structural parts is strictly forbidden by law, and renders the vehicle not conforming to the approved type and therefor dangerous to ride.
CAUTION
RIDING UNDER THE INFLUENCE OF ALCOHOL, DRUGS OR CERTAIN MEDICINES CAN BE EXTREMELY DANGEROUS FOR ONESELF AND FOR OTHERS.
CAUTION
2 Use
ANY ELABORATION THAT MODIFIES THE VEHICLE'S PERFORMANCES, SUCH
AS TAMPERING WITH ORIGINAL STRUCTURAL PARTS IS STRICTLY FORBIDDEN BY LAW, AND RENDERS THE VEHICLE NO LONGER CONFORMING TO

Engine oil level (03_01, 03_02)
03_01
Four stroke engine oil is used in the engines in order to lubricate the timing bodies,
the bench bearings and the thermal group. An insufficient quantity of oil can seriously damage the engine. In all four-stroke engines, a loss of efficiency in oil
performance and certain consumption should be considered normal. Consumption
can particularly reflect the conditions of use (i.e. when driving at 'full acceleration' all
the time, oil consumption increases). The replacement intervals provided for by the
maintenance programme are defined depending on the total content of oil in the engine and the average consumption measured following standardised methods. In
order to prevent any problems, we recommend checking oil level more frequently than indicated in the Scheduled Maintenance table or before setting off
on long journeys. The vehicle is, however, equipped with an oil pressure warning light on the instrument panel.
03_02
3 Maintenance
Engine oil level check (03_03, 03_04, 03_05)
Every time the vehicle is used, a visual check should be made on the level of the
engine oil when the engine is cold. The oil level should be somewhere between the
MAX and MIN index marks on the level bar; the check must be made with the vehicle
upright, resting on the centre stand.
If the check is carried out after the vehicle has been used, and therefore with a hot
engine, the level will be lower; in order to carry out a correct check, wait at least 10
minutes after the engine has been stopped so as to get the correct level.

at an Authorised Piaggio Service Centre.
29
3 Maintenance
CAUTION
Warning light (insufficient oil pressure) (03_06, 03_07)
The vehicle is equipped with a warning light that comes on when the key is turned to
«ON». However, this light should switch off once the engine has been started. If the
light comes on while braking, at idle speed or while turning a corner, it is necessary to check the oil level and top it up if required. If after having topped-up
the oil, the warning light still comes on while braking, at idle speed or while
turning a corner, it will be necessary to take your vehicle to an Authorised Service Centre.
03_06
03_07
3 Maintenance
Engine oil change (03_08, 03_09)
Oil must be changed and filter replaced at an Authorised Service Centre (as indicated in the Scheduled Maintenance Table). The engine should be emptied by
draining the oil through drainage plug «B » of the mesh filter on the flywheel side. In
order to facilitate oil drainage, loosen the cap/dipstick «A». Since a certain quantity of
oil remains in the circuit still, the top-up should be carried out from the cap«A».
Then start up the vehicle, leave it running for a few minutes and switch it off: after
about five minutes check the level and if necessary top up without exceeding the
MAX level.
03_08
The cartridge filter must be replaced every time the oil is changed. For top-ups and
changes use new oil of the recommended type.

Secondary air system (03_18)
In order to reduce polluting emissions, the vehicle is furnished with a catalytic converter in the muffler.
To favour the catalytic process, an extra amount of oxygen is added via a secondary
air system (SAS).
This system allows more oxygen to be added to the unburned gases before they reach
the converter, thus improving the action of the catalytic converter.
The air enters the exhaust duct from the head, and is purified by a black filter.
03_18
The system is fitted with a control valve that disables operation while decelerating to
avoid unwanted noise.

CHAMPION RG6YC - NGK CR7EB
To ensure the best functioning of the SAS system, every 12,000 km the scooter should
be taken to an Authorised Piaggio Service Centre to have the filter cleaned (Scheduled maintenance operations section).
The filter sponge should be cleaned with water and mild soap, then it should be dried
with a cloth and slight blows of compressed air.
CAUTION
CONTACT AN AUTHORISED PIAGGIO SERVICE CENTRE TO CARRY OUT
THESE OPERATIONS.
Checking the brake oil level (03_19)
The brake fluid reservoir is equipped with a sight glass «A» made of transparent material; the quantity of liquid contained in the sight glass indicates the level of liquid in
the reservoir.
When the sight glass «A» is full, the level inside the reservoir exceeds the MIN level;
when it is partially full, the level drops to the MIN level; when it is fully empty, the level
of fluid in the reservoir is below the MIN level.
3 Maintenance
03_19
The brake fluid level may fall due to wear on the brake pads. In case the pad wear is
below the minimum mark, contact an Authorised Service Centre to have the braking
system thoroughly checked. If you need to top up the level, follow the steps listed
below. Unscrew the 2 screws «B», remove the reservoir cap «C » and pour in the
required quantity of fluid (the brake fluid level must be above minimum). Place the
handlebar in the riding position and pay attention not to tilt the vehicle in order to keep
the brake fluid reservoir in horizontal position when checking the fluid level.

Long periods of inactivity
Battery performance will be poor if the vehicle is not used for a long time. This is the
result of the natural phenomenon of battery discharging, and may be due to residual
absorption by vehicle components with constant power consumption. Poor battery
performance may also be due to environmental conditions and the cleanliness of the
poles. In order to avoid difficult starts and/or irreversible damage to the battery, follow
any of these steps:
- At least once a month start the engine and run it slightly above idle speed for 10-15
minutes. This keeps all the engine components, as well as the battery, in good working
order.
- Take your vehicle to a garage (as indicated in the «Vehicle not used for extended
periods» section) to have the battery removed. Have the battery cleaned, charged
fully and stored in a dry, ventilated place. Recharge at least once every two
months.
N.B.
THE BATTERY MUST BE CHARGED WITH A CURRENT EQUAL TO 1/10 OF THE
RATED CAPACITY OF THE BATTERY AND FOR NOT LONGER THAN 10 HOURS.
CONTACT AN AUTHORISED SERVICE CENTRE TO CARRY OUT THIS OPERATION SAFELY. WHEN REFITTING THE BATTERY MAKE SURE THE LEADS ARE
CORRECTLY CONNECTED TO THE TERMINALS.

Idle adjustment (03_37, 03_38)
To adjust idle speed it is necessary to operate the idle set screw «A » located in the
carburettor. To do this,
lift the saddle, remove the rubber cover «B» and use a Phillips screwdriver.
Adjust the idle speed with the rear wheel off the ground (vehicle on stand) and with a
warm engine: undo or tighten the screw until the engine idles smoothly, i.e. without
the rear wheel being moved by the engine. If adjustment in these conditions is difficult,
contact an Authorised Service Centre.

The brake disc and pad wear is automatically compensated, therefore it has no effect
on the functioning of the front and rear brakes. For this reason it is not necessary to
adjust the brakes. An excessively elastic brake lever stroke may indicate the presence
of air in the braking circuit or an irregular brake operation. In this case, particularly
considering the importance of the brakes in terms of safety, it is strongly recommended
that you take the vehicle to an Authorised Service Centre as soon as possible for
the appropriate checks.
WARNING
03_39
CHECK BRAKE PADS FOR WEAR ON A REGULAR BASIS (AS INDICATED IN
THE SCHEDULE MAINTENANCE TABLES). IF THE THICKNESS OF ONE OR
BOTH PADS IS IN THE REGION OF 1.5 MM, BOTH PADS MUST BE CHANGED.
IT IS RECOMMENDED TO CARRY OUT THIS OPERATION AT AN AUTHORISED
SERVICE CENTRE AS SOON AS POSSIBLE.
AFTER FITTING NEW BRAKE PADS DO NOT USE THE VEHICLE UNTIL YOU
HAVE ACTIVATED THE BRAKE LEVER REPEATEDLY TO POSITION THE PADS
AND RESTORE THE LEVER STROKE TO ITS CORRECT POSITION.
CAUTION
BRAKING SHOULD BEGIN AFTER ABOUT 1/3 OF THE BRAKE LEVER STROKE.

lock nut «A».
CAUTION
03_40
BRAKING SHOULD BEGIN AFTER ABOUT 1/3 OF THE BRAKE LEVER STROKE.
Puncture (03_41)
The vehicle is equipped with Tubeless tyres. When there is a puncture, Tubeless tyres
- unlike tyres with inner tubes - go flat very slowly. This offers greater riding safety. A
tyre that goes flat very slowly can be repaired with an "Inflate and Repair" spray. Tyres
should be later fully repaired or replaced at an Authorised Service Centre.
03_41
3 Maintenance
Inactivity of the vehicle
We recommend carrying out the following operations:
1. General cleaning of the vehicle.
2 - With the engine off and the piston at bottom dead centre position, remove the spark
plug and pour 1÷2 cc of motor oil through its hole. Operate the starter motor 3-4 times
letting the engine perform a few revolutions, then remount the spark plug.
52
4 - For the battery, follow the procedures described in the «Battery» section.
5 - Drain the petrol from the carburettor tank.
6 - Replace engine oil.

Cleaning the vehicle
Use a low pressure jet of water to soften the caked dirt and mud deposited on the
painted surfaces. Once softened, sponge off mud and dirt using a car body sponge
soaked in a car body shampoo and water solution (2-4% of car shampoo in water).
Then rinse with abundant water, and dry with a shammy cloth. For the engine exterior,
use petrol, a brush and clean cloths. Petrol can damage paintwork. Remember that
any polishing with silicone wax must always be preceded by washing.
WARNING
To avoid the appearance of oxidations, wash the vehicle every time it is used in
certain areas or in special conditions of:
· Environmental / seasonal conditions: use of salt, de-icer chemical products on
the road in winter.
· Air pollution: city and/or industrial areas.
· Salinity and humidity of the atmosphere: marine areas, hot and wet weather.
53
3 Maintenance
3 - Drain up all the vehicle's fuel; spread antirust grease on the uncoated metal parts;
keep the wheels lifted above the ground.
WARNING
. Prevent deposits from remaining on the bodywork, industrial and pollutant
residual dust, tar spots, dead insects, bird droppings, etc.
· Do not park the vehicle under the trees. In some seasons, in fact, residues,
resins, fruits or leaves may fall from the trees, containing chemicals that are
harmful to the paintwork.
CAUTION
DETERGENTS POLLUTE WATER. THEREFORE THE VEHICLE SHOULD BE
WASHED IN AN AREA EQUIPPED FOR THE COLLECTION AND PURIFICATION
OF THE LIQUIDS USED.
WARNING
NEVER WASH THE VEHICLE UNDER DIRECT SUNLIGHT, ESPECIALLY IN SUMMER WHEN THE BODYWORK IS STILL HOT, AS THE CAR SHAMPOO MAY DRY
BEFORE BEING RINSED OFF, AND COULD DAMAGE THE PAINTWORK. NEVER
USE RAGS SOAKED IN PETROL OR DIESEL OIL TO CLEAN THE PAINTED OR
PLASTIC SURFACES, IN ORDER TO PREVENT THEM LOSING THEIR SHINE
AND MECHANICAL CHARACTERISTICS.
