What’s an easy way to keep your Geoprobe® machine running at peak performance?

We get calls every week, “the engine cranks but will not start or will not run well.” The number one cause is improper fuel system maintenance. Whether it’s a Geoprobe® legacy machine or one in current production, it has at least one, if not two, fuel filters. We recommend changing the filters every 200 hours, making sure to follow the engine priming instructions (see owner’s manual for engine manufacturer recommendations). And NEVER pre-fill a fuel filter for your Geoprobe® rig. If you pre-fill a filter you’re putting unfiltered fuel on the downstream side of the filter element which will contaminate the fuel injection system ... a costly mistake!

If you constantly source your fuel from a tender truck, out of portable fuel cans, or similar sources, expect to change your fuel filters more often. The cleanliness of these sources is marginal, at best. In the winter, it’s best to run a fuel additive as well. If you have a contaminated fuel system, you’ll be changing fuel filters more often, and it’s advisable that you keep an extra set of filters for the machine on hand. If you’re working in a remote area, keep a set of filters with the machine. And always fill your rig’s fuel tank at the end of the day. This will negate condensation collection inside the tank due to humidity/temperature swings which will lead to contamination issues.

Fuel System Maintenance Summary
    •  Service the fuel system at recommended intervals or sooner if conditions warrant
