HEAD
Once  the  water  circuit  is  emptied,  it  is  re-
commended to blow compressed air into 
the  sleeve  connected  to  the  head  in  order 
to  be  sure  there  is  no  fluid  in  the  thermal 
unit.
Once  the  water  sleeve  is  disconnected,  lo-
osen the spark plug, then the seven screws 
that fasten the external cap to the cylinder. 
Lift the head and once it is placed on a le-
vel  surface,  remove  the  spark  plug.  Lightly 
press  the  spark  plug  housing  to  decouple 
the combustion  chamber from the external 
cap.  If  necessary,  proceed  with  the  desca-
ling procedures of the combustion chamber 
and the internal part of the cap.
