Harvey says the major contaminants they have found are rust and dirt, as well as water and algae. "Algae is actually our biggest problem. It lives on water in the fuel and results in a dark-purplish sludge in the tank."Most of the tanks we cleaned are used for irrigation," adds Harvey. "That means they sit out in the middle of a field all year. The exposure to dirt and condensation is probably greater than with a tank sitting at the farmstead." In both of these efforts, the tanks were cleaned by using a Cim-Tek VII fuel recycling system. Country Energy plug-in has helped make these units available to local cooperatives through their KleanSweep program. Fuel is pulled from the bottom of the tank by a suction wand and circulated through a screen and filter element with a 10micron particle rating. Cleaned fuel is then returned to the storage tank.

Haslob has no hard feelings, he told the Register: "I don''t think he meant to do it." But Dupont was fired after the incident, and police have reportedly charged him with reckless endangerment. With the right equipment, you can work like a pro, and make lots of noise, dust and progress.Last week I noticed my neighbor breaking up his sidewalk with a sledgehammer. I strolled over to see how it was going. He had only been at it for an hour but was already sore, exhausted and thinking about hiring a pro to finish the job with a jackhammer. "You don''t need a pro," I told him. "All you need is a jackhammer."

In a hammer drill, the hammering action is provided by spinning disk. The toothed disks rotate against each other, causing the bit to move in and out at more than 40,000 blows per minute.[ILLUSTRATION OMITTED]Although rotary hammers deliver fewer blows per minute, they provide about five times the impact force of a hammer drill. A pneumatic piston powers the striker that transfers impact to the bit. This design reduces operator fatigue and makes drilling more efficient. Unlike the more versatile hammer drill, though, a rotary hammer can''t be used for drilling wood or metal.
