DANGER
•
When draining the fuel tank, avoid spilling fuel, since this
may cause fires.
•
If some fuel is accidentally spilled, clean the dirty area im-
mediately, in order to prevent it from getting slippery and
to avoid fires.
This operation serves to let all the impurities and the condensate
flow out of the tank; open the cock (1) at the base of the tank
and wait until clean fuel flows out.
IMPORTANT
☞
•
The tank must be drained before starting the engine, with
temperatures exceeding 0°C; when the temperature is be-
low 0°C, the tank must be drained at the end of work or in
any case with the machine at operating temperature, to
prevent the condensate from freezing.
•
The condensate and the impurities that may have accu-
mulated inside the tank must be eliminated before refuel-
ling.
