Bleeding the cooling system
To bleed the cooling system, fill in approx. 0.8 liters (0.2 US gallons) of
coolant and remove the bleeder bolt

Then, fill in the coolant until it reaches a level about 10 mm above the
radiator fins.
After a short ride, check the coolant level once more.

cable
Start the engine and, at idling speed, slowly pull the hand

To adjust move back the protective cover
and correct the adjustment screw
