Checking the fuel level
NOTE! The fuel tank should be filled through the fuel filter
neck (4) at the end of each working day. This prevents the for-
mation of condensation water, as far as possible. In case of
excessive contamination of the fuel the fusel tank can be drai-
ned via the drain plug (under the left hand side of the frame).
Draining the fuel prefilter / water separator
Drain the fuel prefilter every 50 operating hours.
Before starting the engine check the sight glass of the fuel prefilter
(5) for the presence of water and dirt, drain through the drain valve
(5.2) if necessary. A ring indicates the condensation water level in
the prefilter.
1 Close fuel tap (5.1). Turn the fuel tap clockwise.
2 Open the drain valve (5.2) and let the collected water flow out.
3 Loosen spigot nut (5.3), remove the fuel prefilter element from
the fuel prefilter glass bowl (5.4) and clean it.
4 Empty the fuel prefilter bowl (5.4). After this reassemble the fuel
prefilter.
5 Close the drain valve (5.2) again.
Replacing the fuel prefilter / water separa-
tor
Replace the fuel prefilter every 500 operating hours.
1 Close fuel cock (5.1). Turn the fuel tap clockwise.
2 Loosen spigot nut (5.3) and remove the fuel prefilter element
from the fuel prefilter glass bowl (5.4).
