DRAINING THE FUEL TANK 4
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.
1. Swing the turret so that the drain valve (1) is positioned
between the tracks.
2. Open the radiator cover. For details, see paragraph
"RADIATOR COVER (3-33)".
3. Open the drain valve (1) and drain the sediments and
water collected at the bottom together with the fuel.
Collect fuel and sediments into a container with suitable
capacity.
4. When clean fuel flows out, close the drain valve (1).
NOTICE
q
The tank must be drained before starting the engine,
with temperatures exceeding 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
operating temperature, in order to prevent the
condensate from freezing.
q
The condensate and the impurities that may have
accumulated inside the tank must be drained before
refuelling.
q
Never use trichloroethylene to wash the inside of the
tank. Use exclusively diesel oil.
