CAUTION
TAMPERING WITH THE CATALYTIC SILENCER MAY CAUSE SEVERE DAMAGETO THE ENGINE.
CAUTION
WHEN PARKING THE VEHICLE, DUE TO THE HIGH TEMPERATURES THE CAT-ALYTIC CONVERTER CAN REACH, ALWAYS BE CAREFUL THAT THE MUF-

FLER DOES NOT COME INTO CONTACT WITH FLAMMABLE MATERIALS, TOAVOID SERIOUS BURNS.
CAUTION
DO NOT SHUT OFF THE ENGINE WHILE THE VEHICLE IS MOVING. UNBURNEDFUEL COULD ENTER THE CATALYTIC CONVERTER AND BURN, CAUSING THECONVERTER TO OVERHEAT AND POSSIBLY DESTROYING IT.
Automatictransmission
To ensure simple, pleasurable riding, the scooter is equipped with automatic trans-mission with regulator and centrifugal clutch. The system is designed to give the bestpossible performance in terms of both acceleration and consumption, on level groundand 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 braketo keep the vehicle still, leaving the motor running at idling speed. Using the motor tokeep the vehicle still can cause the clutch to overheat. This problem is due to thefriction of the clutch parts on the capstan. It is therefore recommended to avoid con-ditions of prolonged clutch slippage leading to clutch overheating (for example,besides the situation described before, driving uphill fully laden on steep slopes orstarting off at greater than 35%In countries where carrying passengers is permitted the maximum admissible slopeis 24%):
1.Do not continue riding in such conditions.
2. Let the clutch cool down with the engine at idle speed for a few minutes.

Safedriving
WARNING
SOME SIMPLE TIPS ARE PROVIDED BELOW WHICH WILL ENABLE YOU TOUSE 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 rec-ommend trying out the vehicle in traffic-free zones to get to know your vehiclecompletely.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.
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 operatethe 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 betweenboth wheels.
6. Avoid starting off by mounting the vehicle while it is still resting on its stand. In anycase, 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 sub-stances from building up within the holes, which can result in early wear of the brakepads.
25
2 Use
8. Any elaboration that modifies the vehicle's performances, such as tampering withoriginal structural parts is strictly forbidden by law, and renders the vehicle not con-forming to the approved type and therefor dangerous to ride.
CAUTION
RIDING UNDER THE INFLUENCE OF ALCOHOL, DRUGS OR CERTAIN MEDI-CINES CAN BE EXTREMELY DANGEROUS FOR ONESELF AND FOR OTHERS.
CAUTION
ANY ELABORATION THAT MODIFIES THE VEHICLE'S PERFORMANCES, SUCHAS TAMPERING WITH ORIGINAL STRUCTURAL PARTS IS STRICTLY FORBID-DEN BY LAW, AND RENDERS THE VEHICLE NO LONGER CONFORMING TOTHE APPROVED TYPE AND DANGEROUS FOR RIDING.

Idleadjustment (03_21)
The idle speed is adjusted by means of the idle speed adjuster screw «A» located onthe carburettor.To do this, proceed as shown in the diagram. Turn the register for adjusting the clear-ance of the throttle control transmission «B», then replace the rubber protection cap.Adjust the idle speed with the rear wheel off the ground (vehicle on stand) and with awarm engine. Turn the knob-type head screw in or out until the engine idles smoothly(around 1700÷1900 rpm.), i.e. without the rear wheel being moved by the en-gine.If adjustment still proves difficult, contact an Authorised Piaggio Service Centre tohave the level of CO when idling fixed (carbon monoxide emissions).
CAUTION
WHEN ADJUSTING IDLE SPEED, BE CAREFUL NOT TO TOUCH HOT PARTS OFTHE ENGINE TO AVOID BURNS.

Frontdiscbrake (03_22)
The brake disc and pad wear is automatically compensated, therefore it has no effecton the functioning of the front and rear brakes. For this reason it is not necessary toadjust the brakes. An excessively elastic brake lever stroke may indicate the presenceof air in the braking circuit or an irregular brake operation. In this case, particularlyconsidering the importance of the brakes in terms of safety, it is strongly recommendedthat you take the vehicle to an Authorised Service Centre as soon as possible forthe appropriate checks.

Cleaningthevehicle
Use a low pressure jet of water to soften the caked dirt and mud deposited on thepainted surfaces. Once softened, sponge off mud and dirt using a car body spongesoaked 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 thatany 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 incertain areas or in special conditions of:
· Environmental / seasonal conditions: use of salt, de-icer chemical products onthe road in winter.
· Air pollution: city and/or industrial areas.
· Salinity and humidity of the atmosphere: marine areas, hot and wet weather.
WARNING
. Prevent deposits from remaining on the bodywork, industrial and pollutantresidual 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 areharmful to the paintwork.
