h Carry out maintenance as described in
chapter 7.8.3 Maintenance and inspection
plan.
Water must be drained daily from the fuel
system through the fuel tank and the fuel pre-
filter.
Collect the fuel/water mixture in a
suitable reservoir. Do not allow it to
seep into the ground or water! Give
to an authorized waste disposal
company to dispose of in an envi-
ronmentally-friendly manner.
Fuel tank

Remove the fuel drain plug (195/1) from
the fuel tank and replace it with the drain
valve from the tool box included in the
scope of supply.
â–º
Screw the drain hose onto the drain valve
and drain the condensate. Once fuel in-
stead of water starts to flow, close the
drain valve.
Keep the level of fuel in the tank high to prevent
condensation from building up.

If the message (196/37) "Water in fuel"
appears in the display, open the drain valve
(193/2) on the fuel pre-filter. Collect the
water/fuel mixture that drains out in a suit-
able container. Close the drain valve
(193/2) when only fuel flows out. Dispose
of the collected water/fuel mixture properly.
