Fuel System; Cleaning/Replacement Of The Fuel Filter Element - Zetor UTILIX CL Operator's Manual

Fuel System

Use only low-sulfur diesel according to EN 590.
IMPORTANT: The diesel fuel system is susceptible to dirt and water, so minimize the risk of
system contamination.

Cleaning/Replacement of the Fuel Filter Element

The fuel filter/water separator (if equipped) is not usually supplied by Yanmar.
The following text describes a typical fuel filter/water separator.
Place a tray under the fuel filter in order to catch any fuel that might spill. Clean up any spilled fuel
immediately.
1. Close the fuel shutoff valve (if equipped).
2. Remove any contamination around the fuel system.
Note: If the fuel filter element is mot equipped with a drain, remove cap. Remove the nylon insert in order to
reduce the lever of fuel in the fuel filter element. A reduction in the level of fuel in the fuel filter element will
help prevent fuel from being spilled when the element is removed.
Notice: Do not use any tool to remove the fuel filter. If you attempt to remove the fuel filter with a filter
wrench or a filter installation aid, the sealing ring may be damaged.
3. Hold fuel filter and rotate quick release collar counterclockwise. Removed and discarded.
Note: If the element is equipped with a sediment bowl, remove the sediment bowl from the element.
Thoroughly clean the sediment bowl. Inspect the O-ring seals. Install new O-ring seals, if necessary. Install
the sediment bowl to the new element. Hand tighten the sediment bowl. Hand tighten the sediment bowl.
Hand tightening is the only method that should be used.
Notice: Do not fill fuel filters with fuel before installing them. Contaminated fuel will cause accelerated wear
to fuel system parts.
4. Make sure the bottom of the fuel filter is clean. Push the new filter element all the way into the bottom of
the fuel filter.
5. Hold the fuel filter in its place. Attach the detent ring. Turn the detent ring clockwise to attach the fuel filter
to the bottom part of the fuel filter.
6. Open the fuel shutoff valve (if equipped).
Important: Never use petrol thinner or any similar flammable material to clean the coarse fuel
filter. Always bleed the system after replacing the filter.
