DRAINING
THE FUEL TANK
The draining of the fuel tank is recommended at times in an effort to remove water and contaminants that
may collect in the tank during normal operation and filling. Avoid refueling with cans because these may
contain traces of water which, being heavier than the diesel fuel, are at the bottom of the can and thus can
be introduced into the fuel tank of the machine.
Periodically open the fuel tank drain to remove the water from the fuel tank. Failure to
periodically drain the tank can allow small amounts of water to be injected into the engine.
It is also advisable to refuel at the end of the work shift to prevent the varying temperature range of the tank
walls from allowing condensation to form in the fuel tank overnight.
In conjunction with draining water from the fuel tank, replacing the fuel filter at the same time can help to
eliminate water from the entire fuel system.
