Draining The Fuel Tank - Komatsu SK818-5 Operation & Maintenance Manual

4.8.1.c

DRAINING THE FUEL TANK

When draining the fuel tank, avoid spilling fuel, since
q
this may cause fires.
If some fuel is accidentally spilled, clean the dirty area
q
immediately, in order to prevent it from getting slippery
and to avoid fires.
This operation serves to let all the impurities and the conden-
sate flow out of the tank.
Proceed as follows:
1 - Raise the engine hood (see "3.5.1 ENGINE HOOD").
2 - Lift the loader arm completely and engage the safety lock
(see "3.1.1 LOADER LOCKS").
3 - Rotate the lever (1) anticlockwise, until only clean fuel
flows out of the pipe connected to the drain cock of the
tank.
4 - Rotate the lever clockwise (1) to interrupt the fuel flow and
close the engine hood.
IMPORTANT
The tank must be drained before starting the engine,
q
with temperatures exceeding 0ºC; when the temperature
is below 0ºC, the tank must be drained at the end of
work or in any case with the machine at operating tem-
perature, to prevent the condensate from freezing.
The condensate and the impurities that may have accu-
q
mulated inside the tank must be eliminated before re-
fuelling.
