SERVICE STATION MANUAL

SR MAX 125 ie

This manual provides the main information to carry out regular maintenance operations on your vehicle.

This manual is intended to aprilia Dealers and their qualified mechanics; several concepts have been

deliberately omitted as they are considered unnecessary. As it is not possible to include complete

mechanical notions in this manual, users should have basic mechanical knowledge or minimum

knowledge about the procedures involved when repairing scooters. Without this knowledge, repairing or

checking the vehicle may be inefficient or even dangerous. As the vehicle repair and check procedures

are not described in detail, be extremely cautious so as not to damage components or injure individuals.

In order to optimise customer satisfaction when using our vehicles, Piaggio & C. S.p.a. commits itself

to continually improve its products and the relative documentation. The main technical modifications and

changes in repair procedures are communicated to all Aprilia Sales Outlets and its International

Subsidiaries. These changes will be introduced in the subsequent editions of the manual. In case of

need or further queries on repair and check procedures, consult Aprilia CUSTOMER DEPARTMENT,

which will be prepared to provide any information on the subject and any further communications on

updates and technical changes related to the vehicle

This section describes the general specifications of the vehicle.

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 naked 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 APRILIA spare parts and lubricants recommended by the Manufacturer. Non-original or

non-conforming spare parts 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 tapered couplings, before refitting these parts.

- 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 vehicle.

- When carrying out maintenance operations on the vehicle that involve the electrical system, make

suretheelectricconnectionshavebeenmadeproperly,particularlythe ground andbattery connections.
