4.8.10.e DRAINING THE FUEL TANK
WARNING
q
When draining the fuel tank, avoid spilling fuel, since this may cause fires.
q
If some fuel is accidentally spilled, clean the dirty area immediately, in order to prevent it from getting
slippery and to avoid fires.
q
Do not smoke and do not use naked flames when carrying out this operation.
q
Wear waterproof gloves and safety goggles, as fuel may be sprayed out.
q
Oils, filters, the coolant and the battery are considered special waste and must be collected and dis-
posed of according to the regulations in force.
CAUTION
q
This operation must be carried out when the fuel level on the indicator is above the reserve mark. Its pur-
pose is to let out any impurity and condensate that may have accumulated in the fuel tank, without let-
ting air into the engine fuel supply lines.
1 - To let the condensate flow out, loosen the drain plug (1) and
wait until no more water is present in the fuel that flows out.
IMPORTANT
q
The tank must be drained before starting the engine, at
temperatures over 0°C; when the temperature is below 0°C,
the tank must be drained at the end of work or in any case
with the machine at a temperature of 40–45°C, in order to
prevent the condensate from freezing when the tempera-
ture drops, thereby making the draining operation impossi-
ble.
q
The condensate and the impurities that may have accumu-
lated inside the tank must be eliminated before refuelling.
