Emptying the float chamber
Should the float chamber need to be emptied, use the following
procedure when the engine is cold. Close the fuel cock and
place pipe 4 in a container to collect the fuel that will flow out.
Open drain screw 5 and drain the fuel. Close the drain screw
again, open the fuel cock and check the seal of the system.
WARNING: Fuel is toxic and highly flammable. Handle it
with the utmost care. Never work on the fuel system near
heat sources or open flames. Always allow the engine to
cool down. Clean any excess fuel with a rag. Materials soaked
in fuel are also highly flammable. In case of ingestion or contact
with sensitive body parts, immediately seek medical attention.
Dispose of fuel in accordance with the law.
Coolant
Check the coolant level when the engine is cold. Follow
these steps:
– Unscrew cap A and visually check the level of the coolant.
When the engine is cold, the liquid should be about 10 mm
above the radiator fins.
– If the coolant does not cover the radiator fins, add coolant un-
til the level is restored.
The capacity of the circuit is shown in the table in Chapter 3.
WARNING: To avoid burns, never unscrew the radiator
filler cap when the engine is hot.
