DANGER
Change the precleaner after work, when the engine has cooled down to 40÷45°C.
When these operations are carried out, fuel may be spilled; clean the dirty areas immediately, in order
to prevent any risk of slipping or fire.
Oils, filters, the coolant and the battery are considered special waste and must be collected and dis-
posed of according to the anti-pollution regulations in force.

4 - Remove the clamp (3) and disconnect the pipe (4) from the
precleaner.
5 - Remove the clamp (5), disconnect the pipe (5) from the used
precleaner and throw the latter away.
6 - Connect the pipes (4) and (6) to a new precleaner and fasten
them with the clamps (3) and (5).

ply circuit (See "4.7.9.b CHANGING THE FUEL FILTER").
