ABS ANTI-LOCK BRAKING SYSTEM
PRECAUTIONS
PRECAUTIONS DURING THE MAINTENANCE OF THE ABS
A series of important precautions must be adopted during the maintenance of the ABS system.
•
The ABS system has been designed to be fed by a 12V sealed battery. Do not use any other type of battery, only sealed 12V.
•
Do not invert cable connections of the battery. It would damage the ABS hydraulic unit.
•
To avoid damage to the ABS components, do not disconnect the battery cables or other electrical connections when the start
switch is positioned at ON or when the engine is running.
•
Be careful to not cause a short circuit between the cables directly connected to the positive terminal (+) of the battery and the
Earth of the frame.
•
Do not position the start switch at ON whilst the ABS electrical connectors are disconnected. The hydraulic unit
•
of the ABS memorises the maintenance codes.
•
Do not spray water onto the electrical components, the components of the Abs, cables, connectors or the cabling.
•
If there is a transmitter/receiver installed on the motorcycle, ensure that the functioning of the ABS system is not disturbed by
electromagnetic waves irradiated by the antenna.
•
Position the antenna as far away as possible from the hydraulic unit of the ABS.
•
Position the start switch at OFF before disconnecting the electrical connections of the ABS.
•
The components of the ABS must never be hit, for example by a hammer or must not be dropped onto a hard surface. These
impacts could cause damage to the components.
•
The ABS components cannot be disassembled. Even if there is a fault, substitute the ABS unit, do not try to disassemble and
repair the components.
•
The ABS system is made up of numerous circuits, tubes and cables of the brakes.
•
Furthermore, the ABS system is not capable of detecting problems of the conventional braking system (abnormal wear of the
brake discs,
•
brake pads and other mechanical faults). To avoid inconveniences, check that the brake circuits and tubes are arranged and
connected correctly, the cabling is opportunely laid out and the brakes are equipped with adequate braking power.
•
Check that there are no leaks of fl uid and then accurately bleed the brake circuits.
IMPORTANT NOTICE
Air in the brake tubes reduces the braking power that could cause a serious accident with severe injuries and even death. If
any union of the brake circuit, including the nuts of the ABS hydraulic unit joint, or the bleed valve are opened, the air entered
into the system must be completely bled from the brake circuit. If the brake lever is spongy when pressed, there could be air
in the tubes of the brake circuit, or the brake could be defective. In that case, do not use the vehicle and immediately repair
the brake system.
IMPORTANT NOTICE
Do not use the motorcycle if there is air in the brake circuit, otherwise the ABS system could function incorrectly.
IMPORTANT NOTICE
The use of tyres that are not recommended could cause malfunctioning of the ABS system and cause an increase in the
braking distance thereby causing a serious accident with severe injuries and even death. Always use the recommended
standard tyres for this motorcycle.
