WARNING
Water contained in the fuel can corrode, damage or
wear the engine injection system.
NOTE: the WX 145 excavator is equipped with fuel
filter. The WX 165 and WX 185 excavators are
equipped with two fuel filters.
The fuel filters have the aim to filter impurities and to
separate the water contained in the fuel. The fuel fil-
ters are equipped with a preheating device and with
a water sensor.
The fuel filters are installed inside of the engine
compartment, in front of the engine and are accessi-
ble through the rear right cover.
A sensor (1) is fastened on the draining valve (2) of
the filters (3), this sensor activates the yellow lamp
(5) on the multi-function display, when the presence
of water is detected inside of the fuel filter separator.
A brief warning is sounded at the same time.
Beyond the error code 7048, in the middle lower
section of the multi-function display (4) appears a
short description of the error code:
"Error water in fuel sensor".
S
WARNING
Drain immediately water from the filter, when on the
multi-function display lights up the yellow lamp (5)
and the error code 7048 is shown. If within 30 min-
utes the error code is shown again, water has nec-
essarily to be drained from the tank.
Open the cooler side cover on the right side of the
upper structure.
Now the fuel filters (3) are accessible.
Place a container below the filters to collect the
water to be drained.

pulling it downward.

of the filter. Water drains.
