Fuel Prefilter Water Separator
The fuel prefilter is equipped with a water separator. An
electronic water level sensor signals when the maximum
permissible water level is reached inside the water
separator. To drain the water separator, perform the
following procedure:
1. Place a suitable container under the drain socket of
the drain plug (Figure 50).

2. Open the drain plug to drain water into the container.
3. As soon as fuel escapes, close the drain plug.
4. Dispose of the water/fuel mixture in an environmentally
responsible manner.
FUEL FINE FILTER
Replace the fuel fine filter every 500 hours or every 2 years.
1. Block the fuel feed line using the hose clip (Figure 51).

2. Place a suitable container under the filter to collect
emerging fuel.
3. Unscrew the fuel fine filter with a strap wrench
(Figure 51) and dispose of the filter according to local
environmental regulations.
4. Lightly oil the gasket of the new fuel fine filter. Install
the filter and tighten it by hand.
5. Release the fuel feed line.
OIL AND FUEL LINES
1. Check the oil and fuel lines and connections regularly
for leaks or damage. Repair or replace as necessary.
2. Replace the oil and fuel lines every two years to
maintain performance and flexibility.
V-BELT
Visually examine the V-belt (Figure 52) and determine if it
is full of tiny cracks, frayed, has pieces of rubber missing,
is peeling, or is otherwise damaged.

Also, examine the belt and determine if it is oil soaked
or 'glazed' (a hard, shiny appearance on the sides of the
belt). Either of these two conditions can cause the belt to
run hot, which can weaken it and increase the possibility
of it breaking.
Replace the V-belt immediately if it exhibits any of the above
wear conditions.
