Rules
This section describes general safety rules for any maintenance operations performed on the vehicle.

Safety rules

•
Should it be necessary to keep the engine running while servicing, make sure that the area
or room is well ventilated, and use special exhaust fans, if required. never let the engine run
in an enclosed area. Exhaust fumes are toxic.
•
The battery electrolyte contains sulphuric acid. Protect your eyes, clothes and skin. Sul-
phuric 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.
•
Fuel is highly flammable, and in some conditions it can be explosive. Do not smoke in the
working area, and avoid open flames or sparks.
•
Clean the brake pads in a well ventilated environment, directing the compressed air jet so
as to not inhale the dust produced by the wear of the friction material. Even though the latter
contains no asbestos, dust inhalation is harmful.
Maintenance rules
•
Use original PIAGGIO spare parts and lubricants recommended by the Manufacturer. Non-
original or non-conforming spares may damage the vehicle.
•
Use only the special tools designed for this scooter.
•
Always use new gaskets, sealing rings and split pins upon reassembly.
•
After removal, clean the components using non-flammable or low fire-point solvent. Lubri-
cate all the work surfaces except the tapered couplings before refitting.
•
After reassembly, check that all components have been installed properly and that they are
in good working order.
•
For removal, overhaul and reassembly operations use only tools provided with metric meas-
ures. Metric bolts, nuts and screws are not interchangeable with coupling members with
English measurement. Using unsuitable coupling members and tools may damage the
scooter.
•
Should any interventions to the scooter electrical system be required, check that the elec-
trical connections - especially earth and battery connections - have been implemented
properly.
