4.7.3.f DRAINING THE WATER SEPARATOR
DANGER
•
Fuel is flammable; neither use naked flames, nor smoke
while draining the water separator.
•
If some fuel should inadvertently be spilled, clean the dirty
area immediately.
This operation serves to drain the condensate water and must be
carried out with full tank, in order to prevent air from entering the
fuel supply circuit.
The condensate must be drained at the end of work, before the
engine has completely cooled down, in order to prevent freezing if
the temperature gets very low.
The water separator can be reached by opening the engine hood
(see “3.5.1 ENGINE HOOD”).
The condensate must be drained by loosening the plug (1) and
waiting until only clear diesel oil flows out. (Use a 13 mm span-
ner).
