Temperature drop brings drips.

COOL MORNINGS MEAN CONDENSATION CAN BUILD UP IN MY FUEL. THAT MAKES FOR ROUGH RUNNING IF YOU DON'T DRAIN IT!

A temperature drop means you'll have to do more than just grab a jacket, operators. Colder temps bring condensation that forms on the inside of your hydraulic excavator's fuel tank.

Water and fuel aren't a good mix. Water's bad enough, but it also lets crud grow inside your fuel tank. If you don't get it all out, the engine runs rough-or not at all.

To get that water and crud out, you need to drain the fuel/water separator on your Model 230 and 330 HYEX before every day's run. The separator is located behind the engine access door on the left side of the excavator.

Open the separator by turning its drain cock counterclockwise. Then push down on the press pump to get water out of the separator.

Some fuel is going to come out with that water, so make sure you dispose of it in an approved hazardous waste container. Never dump it down a drain or on the ground from the separator's drain hose.

The fuel should run clear after a few seconds. If it doesn't, close the valve and report it to your mechanic.

Draining the fuel/water separator for the Model 240 HYEX is handled differently. See WP 0086 in TM 5-3805-294-10 (Mar 11) for the specifics.
