Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids. Dispose of all fluids according to local regulations and mandates. |
Fuel quality is critical to the performance and to the service life of the engine. Water in the fuel can cause excessive wear to the fuel system.
Water can be introduced into the fuel tank when the fuel tank is being filled.
Condensation occurs during the heating and cooling of fuel. The condensation occurs as the fuel passes through the fuel system and the fuel returns to the fuel tank. This causes water to accumulate in fuel tanks. Draining the fuel tank regularly and obtaining fuel from reliable sources can help to eliminate water in the fuel.
Drain the Water and the Sediment
Fuel tanks should contain some provision for draining water and draining sediment from the bottom of the fuel tanks.
Open the drain valve on the bottom of the fuel tank in order to drain the water and the sediment. Close the drain valve.
Check the fuel daily. Allow 5 minutes after the fuel tank has been filled before draining water and sediment from the fuel tank.
Fill the fuel tank after operating the engine in order to drive out moist air. Helping to prevent condensation. Do not fill the tank to the top. The fuel expands as the fuel gets warm. The tank may overflow.
Some fuel tanks use supply pipes that allow water and sediment to settle below the end of the fuel supply pipe. Some fuel tanks use supply lines that take fuel directly from the bottom of the tank. If the engine is equipped with this system, regular maintenance of the fuel system filter is important.
Drain the water and the sediment from the fuel storage tank at the following intervals:
- Weekly
- Service intervals
- Refill of the tank
Helping to prevent water or sediment from being pumped from the storage tank into the engine fuel tank.
If a bulk storage tank has been refilled or moved recently, allow adequate time for the sediment to settle before filling the engine fuel tank. Internal baffles in the bulk storage tank will also help trap sediment. Filtering fuel that is pumped from the storage tank helps to ensure the quality of the fuel. When possible, water separators should be used.

Drain valve (1) is located at the bottom of the fuel tank in the belly pan of the machine.
- Open the drain valve and allow the water and sediment to drain into a suitable container.
- Close the drain valve.
Note: If water and sediment are regularly found at weekly maintenance intervals, drain the sediment daily.
