SERVICE STATION MANUAL
Beverly 125
This service station manual has been drawn up by Piaggio & C. Spa to be used by the workshops of
Piaggio-Gilera dealers. This manual is addressed to Piaggio service mechanics who are supposed to
have a basic knowledge of mechanics principles and of vehicle repairing techniques and procedures.
Any significant changes made to the vehicle characteristics or to specific repair operations will be
promptly communicated by updates to this manual. Nevertheless, no work can be satisfactory if the
necessary equipment and tools are not available. It is therefore advisable to read the sections of this
manual relating to special tools as well as the tool catalogues.
N.B. Provides key information to make the procedure easier to understand and carry out.
CAUTION Refers to specific procedures to carry out for preventing damages to the vehicle.
WARNING Refers to specific procedures to carry out to prevent injuries to the repairer.
Personal safety Failure to completely observe these instructions will result in serious risk of personal
injury.
Safeguarding the environment Sectionsmarked with this symbol indicatethe correct use of thevehicle
to prevent damaging the environment.
Vehicle intactness The incomplete or non-observance of these regulations leads to the risk of serious
damage to the vehicle and sometimes even the invalidity of the guarantee.

Rules
This section describes general safety rules for any maintenance operations performed on the vehicle.
Safety rules
- If work can only be done on the vehicle with the engine running, make sure that the premises are well-
ventilated, using special extractors if necessary; 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. 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.
- Fuel 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 brake 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 friction material. Even though the latter
contains no asbestos, inhaling dust 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 appropriate tools designed for this vehicle.
- Always use new gaskets, sealing rings and split pins upon refitting.
- After removal, clean the components using non-flammable or low flash-point solvents. 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 removal, 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
suretheelectricconnectionshavebeenmadeproperly,particularlythegroundandbatteryconnections.

Air is drawn through the opening «A», goes through the first filter and is channelled through the opening
«B».
Air gets to the second filter «B» through the opening shown in the figure. Now, the filtered air enters
the diaphragm device, and then is channelled to the head.
The air passes through a rigid pipe connected to the head and reaches a discharge joint in order to
supply oxygen to the unburned gases before the catalytic converter, thus favouring an improved reac-
tion of the catalytic converter.
