5.13.1. FUEL TANK
Check the fuel level at the gauge on the instrument panel. To prevent moisture due to condensation,
the fuel tank must be filled at the end of each day’s operation.

FUEL STRAINER (if equipped)
The fuel strainer is installed in the filler pipe. Access is possible upon the removal of filler cap (1)
and retainer. The fuel strainer performs a coarse filtration of fuel facilitating the operation of the fuel
filters. Keep the fuel strainer clean. Use kerosene or diesel fuel for cleaning.
FUEL TANK BREATHER
The breather is located on the right side of the fuel tank, close to the engine crankcase. Access is
possible upon lifting the hood (Fig. 5.48, 5.48A and 5.48B) or the radiator grill (Fig. 5.48A). Clean the
breather with a suitable solvent and dry with compressed air.
DRAINING WATER
Drain water daily before starting the operation of a machine. Remove drain plug (2) located on the
front wall of the tank in its lowest point. Wait until clean fuel starts to flow. Reinstall the drain plug.
Drain fuel to a clean container. Allow water and sediment to collect on the bottom of the container
and refill the clean fuel collected above the sediment and water.
5.13.2. CHANGING THE FUEL FILTERS
1. There is a strainer in the fuel line (Fig. 5.31A). The strainer must be periodically replaced. Before
replaced, it is necessary to close the fuel shut valve located under fuel tank and loosen the
hoses farting clamps. Install the new strainer that way the arrow on the strainer is orientated the
fuel flow.
2. The engine is equipped with two filters (one with water separator). The filters must be replaced
every 500 hours of operation or every 6 months. Lift the hood (Fig. 5.48, 5.48A and 5.48B), clean
the area around the fuel filters. Using a filter wrench, remove the fuel filters (Fig. 5.30), remove
the O-ring. Clean the fitter gasket surfaces of the filter header for each filter (Fig. 5.31). Fill the
new filters with clean diesel fuel. Install the new O-ring supplied with a filter. Then apply a thin
coat of clean engine oil to the seal of the filter. Install the filters on the filter header.
