MAINTENANCE
Fuel system
☛
ATTENTION! Do not work close to an open fire and do not smoke when working on the fuel system.
Water separator inspection:
-
Turn hex screw „v“ 2 - 3 turns to detach.
-
Collect the emerging drops in a transparent container.
First water and then fuel drops will emerge, as water is
specifically heavier than diesel fuel. A clear separating line
will make this easily recognizable.
-
Turn the hex screw „v“ back in once only clear fuel emerges.
Fuel filter replacement:
-
Place an appropriate container under the filter to catch
any emerging fuel.
-
Close fuel supply line.
-
Pull fuel line „w“ off from both sides of the fuel
filter „x“ and then put in a new filter.
Important:
Pay attention to cleanliness and avoid letting any
dirt into the fuel line.
-
Always replace fuel filter. Pay attention to the flow
direction - look for the arrows.
-
Allow fuel to flow.
-
After a short test run make sure that fuel filter and line
do not leak.
Screwed connections control:
Make sure all accessible screwed connections are correctly
tightened and in good shape.
☛
ATTENTION!
Do not retighten cylinder head screws!
The adjusting screws for the speed governor
and at the injection system have been provided
with a safety lacquer; do not retighten nor
reset them.
