Workshop Manual
4.3. Functional test
A functional test needs to be carried out at the
end of each servicing operation, to check that the
operations made are effective. The test must be
performed in compliance with the safety regula-
tions regarding the use of the lawnmower on which
the engine is installed.
The functional test is carried out as follows:
a. Refuelling and checking the supply system
When you have refuelled the tank with new petrol,
check the seal of the tank, the cap and the car-
burettor pipe.
b. Hot and cold starting test
The engine is equipped with intelligent starter sy-
stem (AUTO-CHOKE), perform some cold and hot
starts to make sure they happen regularly
c. Check the engine rpm
When the engine is hot enough, check the engine
speed; the reading should be equal to the speci-
cations [
3.2].
If all of these operations have a positive result, the
engine can be considered fully serviceable and be
returned to the client.
