Storage, Maintenance And Cleaning - ARGENTO Alpha Manual De Instrucciones

Brakes
The braking system installed on the product provides for the presence of mechanical disc brakes that can be operated on the
front wheel and on the rear wheel through the corresponding levers positioned on the handlebar, individually equipped with a
device (cut-off sensor) through which, by operating the brake lever to which it is connected, the immediate disengagement of
the propulsive action of the motor takes place.
The brake lever on the right side of the handlebar activates the rear brake and stops the rear wheel whereas the brake lever
on the left side of the handlebar activates the front brake and stops the front wheel.
The front and rear brake levers must be positioned and adjusted so they are comfortable to use and favour the natural
position of the hand and fingers used to pull them, thus minimising the force and amount of time required to pull the brake
lever whilst ensuring that the brake is applied evenly.
Check the operation of the brakes with a low speed brake test (max 6km/h) in an obstacle-free zone.
As the brake pads on the callipers become worn and their thickness is reduced, the brake lever will have to be pulled further
to exert the same braking force.
To compensate for this type of wear, it will be necessary to act on the adjustment ring nut of the brake cable, located behind
the corresponding lever, to restore the optimal braking conditions; in the presence of excessive wear of the brake pads, a
replacement will be necessary.
Gear change and drive
The cable gear change system supplied with the product is indexed and allows you to change the gear ratio and pedal
stroke metrics by adjusting the control device on the handlebar, determining the sideways movement of the chain on the
corresponding sprocket of the cassette installed on the rear wheel via the derailleur.
Make sure the gear change and its adjustment are correct and that the chain and drive gears are clean and properly
lubricated.
Wheels and tyres
Check the correct centring, suitable tensioning of the spokes and correct installation and tightening of the pass-through pins
and/or the quick release mechanism of the front wheel (if present).
Check the presence and correct installation of the reflectors.
Check the condition and state of wear of the tyres: there must be no cuts, cracks, foreign bodies, abnormal swelling, visible
canvases and other damage.
Check the tyre pressure by referring to the specific range of minimum and maximum values shown on the side of the tyre
(suitable pressure must be customised according to the weight being carried, the weather conditions and road surface).
Properly inflated tyres, in addition to improving wheel slip, reduce the risk of punctures and deterioration.

9. Storage, maintenance and cleaning

To ensure and maintain a good level of safety and functionality of the bike, it must be regularly checked and periodically
serviced.
Some checks and servicing tasks can be carried out directly by the user or anyone who has basic mechanical skills, ability and
access to the right tools.
Other operations require the expertise and specific tools of a qualified operator.
The dealer will be able to provide all the information about the checks which can be carried out directly by the user and
suggest which routine maintenance tasks should be periodically carried out based on how frequently the bike is used and the
conditions of its use.
All the maintenance operations must be performed with the battery detached and the bike resting on the kickstand.
The different parts that make up the bike are subject to various types of wear from use.
In particular, the following components should be regularly checked and serviced: tyres, wheels, brakes, gears, chain,
suspension and frame.
The tread of the tyres installed on the bike is liable to be consumed which can be accentuated by how and where it is used.
The rubber of the tyres also tends to harden over time.
The correct pressure of the inner tube in the tyres should be constantly checked to reduce the risk of punctures, limit
deterioration and ensure safer use and performance of the bike.
Periodically inspect the state of wear and ageing/deterioration of the tyres and replace the tyres, if necessary, with ones that
have the same characteristics.
