The nominal size of a rotary hammer, on the other hand, refers not to the capacity of the chuck, but to the largest hole that the manufacturer recommends drilling with it. There are three classes of rotary hammers on the market, each of which uses a different--and noninterchangeable--chuck design.SDS-plus rotary hammers are designed for drilling holes from 5/32 inch to 3/4 inch. Because most masonry drilling falls into that size range, this is the most popular class of tool. SDS-plus rotary hammers are also available in cordless versions.

Gene Gall, sales manager for the Cim-Tek unit from Central Illinois Manufacturing, Bement, Illinois, says fuel suppliers who use the unit typically learn the same thing. "There''s a lack of proper fuel maintenance on many farms. Farmers don''t change tank filters regularly, and they don''t drain deposits from the bottom of tanks."Caring for stored fuelChuck Hamilton, technical service engineer with Country Energy in Minneapolis, Minnesota, says 90% of the diesel fuel problems he sees are from dirt, rust, and water contamination. "Even many cold-weather problems are from water contamination, not fuel gelling. The vast majority of these problems can be eliminated with proper fuel tank maintenance on the farm," he says.

While the analyst views the moves positively, he says "much bolder moves are necessary" to bring return on assets up. The C316 series cold saws have a vertical column construction that is said to provide stable saw frame guidance, resulting in vibration-free sawing. The saws can operate in a conventional 90 degree cutoff mode, or with the turn of the locking lever, the saw frame can be swiveled to any angle up to 45 degrees left or 60 degrees right for miter sawing. The mitering device has a visible vernier scale and a preset zero return stop. The saws are available in a completely manual model, or a manual model with a quick-clamping air vise.According to the company, all saws feature a precision-ground saw bed, heavy-duty drive and TEFC motors, enclosed transmission, full coolant system, removable full blade guarding and a powered rotary brush cleaner to eliminate plugging and loading that can cause premature blade failure. The beauty of snoring is that the perpetrator can plead temporary amnesia and get away with it. After all, you can saw wood for hours without disturbing yourself. To your other half, however, it''s like sleeping next to a landing strip. And that, unless you''re strictly into one-night stands, is the reason why many guys finally do something about it.
