Safety guidelines

- If work can only be done on the vehicle with the engine running, make sure that the premises are well ventilated, using special extractor fans if necessary; never let the engine run in an enclosed area. Exhaust gasses are toxic. The battery electrolyte contains sulphuric acid. Protect your eyes, clothes and skin. Sulphuric acid is highly corrosive; in the event of contact with your eyes or skin, rinse thoroughly with abundant water and seek immediate medical attention. The battery produces hydrogen, a gas that can be highly explosive. Do not smoke and avoid sparks or flames near the battery, especially when charging it. Petrol is highly flammable and it can be explosive given some conditions. Do not smoke in the working area, and avoid open flames or sparks.

- Clean the blocks, the drums, and pads in a well ventilated area, directing the jet of compressed air in such a way that you do not breathe in the dust produced by the wear of the blocks. Dust caused by shoe wear is toxic since it contains asbestos.

Maintenance guidelines

Use original PIAGGIO spare parts and lubricants recommended by the Manufacturer. Non-original or non-conforming spares may damage the vehicle. Use only the appropriate tools designed for this vehicle. Always use new gaskets, sealing rings and split pins upon refitting. After removing these components, clean them using a non-flammable or high flash-point solvent. Lubricate all the work surfaces except the tapered couplings before refitting. After refitting, make sure that all the components have been installed correctly and work properly. For disassembly, overhaul and refit operations use only tools with metric measures. Metric bolts, nuts and screws are not interchangeable with coupling members with English measurement. Using unsuitable coupling members and tools may damage the scooter. When carrying out maintenance operations on the vehicle that involve the electrical system, make sure the electrical connections have been made properly, particularly the ground connections.

TECHNICAL DATA

Specification Desc./Quantity

Fuel system Mixer petrol - oil through automatic carburettor/mixer (with

slave bearing to the engine speed and throttle valve opening)

and a gravity system.

Lubrication Carried out by the oil mixer for: piston, cylinder, crankshaft,

bearing of the flywheel side bench.

Electronic ignition Consists of a capacitive discharge type device with H.V. coil

AT built-in. The system allows you to obtain a spark with a high voltage value, reached in very short time, and with a much reduced discharge duration, so it results in regular operation even with a dirty spark plug, easy cold starting, excellent combustion, limited wear of the electrodes and inalterability of the timing due

to the lack of components subject to wear.

Transmission From the crankshaft to the rear wheels through the clutch,

gearbox - differential - axle shaft.

Clutch Multiple discs in oil bath.

Transmission With four speeds with always driven gears.

Crankshaft alignment check

With the proper equipment, check that the eccentricity of the surface of Ø "3"and "1" are contained within 0.003 mm. (the maximum reading limit on the dial gauge clock); Also check the eccentricity of Ø "2", which are allowed for a maximum reading of 0.02 mm. In the case of eccentricities not much greater than that prescribed, perform the straightening of the shaft by means of counterweights with a wedge, or tightening it in a vice (equipped with aluminium bushings) as needed, for much greater eccentricities replace the crankshaft.

Check the charge of the battery. If necessary replace the battery.

Scheduled maintenance chart

The following table must be regarded as a general guide for periodic inspections and lubrication interventions. It is necessary to also consider the weather, terrain, geographic location and variety of special use. This interventions table must therefore be changed to reflect the particular needs of the owner. For example, if a vehicle is exposed to sea salt, all parts should be lubricated more frequently than shown in the table to prevent damage caused by corrosion to metal parts.

Interventions

The failure of the alternate current section of the voltage regulator can cause, depending on the type of fault, the following problems:

1) Burning of the bulbs (regulator stopped).

2) Operation failure of the lighting (short circuit in the regulator).

FAILURE 1

Replace the regulator because it is securely inefficient.

FAILURE 2

a) Check the correct current output of the alternator: disconnect the grey regulator cable, place a voltmeter between the cable and ground to detect the alternate current voltages and to check that the output voltage at 3000 rpm is greater than or equal to 20V. b) If the checks carried out disclose no failures, replace the regulator. c) If replacing the regulator does not restore proper operation, proceed to the checks of the electrical system connections.

interventions

The failure of the direct current section of the voltage regulator can cause, depending on the type of fault, the following problems:

3) Burning of the protective fuse (short circuit in the regulator) and subsequent battery recharge failure.

4) Battery recharge failure(regulator stopped).

FAILURE 3

Replace the regulator, because it is securely inefficient and replace the protective fuse.

FAILURE 4

a) Insert an ammeter between the regulator and the battery and verify that the current ouput at 3000 rpm is greater than 1 amp, with the battery maintained at 13V. If the values are lower than required, replace the regulator.

Controllo impianto di accensione

All system check operations involving disconnection of the cables (inspections of connections and devices that are part of the ignition circuit) must be made with the engine turned off: otherwise the control unit could be irreparably damaged. It is therefore important and necessary that in case of removal of the cables, when refitting attention is paid to correctly reconnecting each cable to the corresponding coupling respecting the distinct colour codings.

KEY: 1 = Red 2 = White 3 = Green

INSPECTIONS TO BE PERFORMED IN THE EVENT OF IGNITION IRREGULARITIES

In the event of failure and abnormal operation of the ignition, whose causes are not detectable by a visual inspection, it is necessary first to replace the control unit with a corresponding, safely functional replacement. Remember that the disconnections and connections to replace the control unit must be performed when the engine stopped. If replacing it restores the ignition operation, the fault lies in the control unit, which obviously needs to be replaced. In the event that the failure persists, it is necessary to carry out checks on the alternator and on the stator parts as follows: After a visual inspection of the electrical connections, measurements are carried out on the loading coil and on the pick-up using an Ohm meter, capable of detecting the resistance from 1 to 1000 ohms.
