To bleed the air, with the circuit completely drained
from the coolant, proceed as follows:

• Fit a tube in the coupling (A) of the bleed nipple on the
cylinder head.
• Refill the expansion reservoir with coolant, as
described: (S/B - P. 16).
• Release and remove the filler (B).
• Pour some coolant in the main radiator (left).
• Slacken the coupling (A) and go on refilling the main
radiator until some liquid would drip off the tube (with
regular flow).
• Now, close the bleed nipple (coupling - A) and fill in up
to the rim of the main radiator.
• Slacken the bleed screw (C), until some liquid drips off
with regular flow.
• Close the screw and top up the liquid.
• Open the bleed nipple on the cylinder head and check the
tubes for liquid dripping, showing that the bleeding has
been correctly carried out.

slacken the screw (D), to let any remaining air out of the
right radiator.
• Tighten the bleed screw (D), which act as the ground
screw.
• Open the bleed nipple on the cylinder head and check
the tubes for liquid dripping, showing that the bleeding
