ARGENTO E-Bike Piuma Mode D'emploi page 40

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 by performing a braking test at low speed (max 6km/h) in
an area free of obstacles.
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.
If the bike has a mechanical disc braking system, to compensate for this type of wear,
the brake cable adjustment ring located behind the corresponding lever will need to be
adjusted to restore optimal braking conditions; if the brake pads are very worn, they must
be replaced.
If hydraulic disc brakes are present, progressive wear of the pads installed on the relevant
callipers, which reduces their thickness, will be automatically compensated for by the valve
system supplied with the braking system, guaranteeing the same braking efficiency until the
pads are worn out and need replacing.
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 for the presence and correct installation of the reflectors.
Check the condition and state of wear of the tyres. There must not be any cuts, cracks,
foreign bodies, unusual swelling, visible inner tube or 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).
Correctly pumped tyres reduce the risk of punctures and deterioration as well as improving
the movement of the wheel.
