STIHL It could be the last chain saw you’ll buy. Here’s why; 1 Its precision made cylinder is designed to last longer In fact, twice as long 2 Hot chamber magnesium die castmg makes the housing tougher It also makes it lighter 3 The fuel and oil open ings are on top, so you won't spill one when you fill the other 4 The large metal fuel tank stores more fuel. Engine operating efficiency keeps it there longer. 5 The stainless steel fuel filter filters out everything but the fuel. 6 The faster the chain moves, the faster the gear driven automatic oil pump pumps But it only pumps when the chain is moving, which saves you oil when it's not 7 The oil tank is designed so you won’t have to stop for oil before you stop for fuel 8 The twin level air in take design keeps the engine cool and running And that keeps you cool and cutting 9 The sprocket-nosed guide bar increases power and helps eliminate friction Which helps eliminate wear Which helps eliminate broken chains as well as the time and money it takes to replace them 10 A threaded stainless steel insert keeps you from stripping out the spark plug hole And that keeps you from having to buy a new cylinder to replace it 11 A piston ported cylinder rather than an outdated reed valve system adds power to the engine, life to the saw, and nothing to the cost 12 A sophistocated muf fler makes it quieter, so you'll be able to hear yourself think ing about what you're doing 13 The muffler is enclos ed in the housing If you’ve ever burned yourself on a hot muffler, you'll know why 14 With over 4,000 Stihl dealers across the country, parts and service are no pro blem That is, if you ever need parts or service 15 We invented the chain saw 50 years ago Everything we learned about chain saws and woodcut ting in those 50 years has been in corporated into the Farm Boss Quite frankly, no other saw in the world could touch it 16 Because It's a Stihl.

The result is additional safety and health protection which the public is willing to bear. Acknowledging that this new awareness and approach to chemicals has saddled chemical companies .with increased costs, the EPA spokesman said much of the agency’s work involves reviews of old chemicals, let alone clearing new ones. “It’s a new ballgame -"one which din’t exist in 1955,” the spokesman added. Under present govern ment patent rulings, ex clusive rights to a chemical are good for 17 years. During that tune, no one but the registrar of a product may manufacture or sell it. Ther e’s a catch, though. As soon as a compound shows possiblities as a pesticide, herbicide or fungicide, the company developing it will immediately apply for a patent to protect their discovery. But, not an ounce may be merchandised until the compound is throughly tested and approved jiy various agencies. And, that may take up to eight out of the 17 exclusive-rights years to accomplish. Holding the two heaviest hatchets over the newly developed chemicals are the federal Environmental Protection Agency and Pennsylvania’s Department of Environmental Resources v “EPA keeps changing their regulations on test data requirements,” Cun ningham notes. “More and more samplings and results continue to be required.” Researchers hunting marketable chemicals must fust determine on what crops a new compound might be effective. " “A crop must be profitable enough for growers to buy ■' the chemicatTto-use on it,” adds the technician. Growers of specialty crops are probably the first to suffer from the huge costs incurred in proving test data. Companies are in creasingly reluctantio begin multi-million dollar research programs on compounds with obviously limited demand. Determining rates of usage is the next step in development. What applied poundage per acre will benefit the crop? How much more will destroy it? It may take up to three years of planting and lab scrutinizing Lancaster Farming, Saturday, September 10,1977 to computerize the needed data on promising products. If a chemical make-up shows its worth after the inital steps, the pointed fingers of intense en vironmental screening become the next challenge. All plant chemicals must pass residue teste. How long must the product be with drawn before harvesting the fruits or vegetables for human consumption? Does it pose any potential health problems to picking crews? If the crop is for animal feedstuffs, like alfalfa or clover, long-term tests must be carried out on herds of animals. Is any residue coming through the milk, meat, or eggs? Are there side effects to the animals themselves? Finding an swers to these questions comprise one of the most crucial and time-consuming steps in the complicated procedure. Grains such as wheat and com, which may be destined for use in processed flours and cerals, add another angle to testing. Does the chemical show up in the flour, and thus eventually in the loaf of bread or box of cornflakes brought home by American consumers? Chemicals are also scrutinized intensely as to how they might affect nature. Any spraying done over fields and streams may also involve the Department of the Interior. Census checks before and after spraying will be made of birds and wildlife, as well as on the insects they consume as food. Honeybees must not be harmed. Acquatic insects and larvae can not be killed, because they, too, are part of the food chain of fish and water-based species. “You’ve got to get all the bad guys while not harming the good guys,” is Cun ningham’s summation of the entire process. “But it protects the environment, it protects the grower, and it protects the company.” In line with the increasing regulations, farmers across Pennsylvania will be required after October 1 to be certified for purchase and use of all chemicals bearing the warning symbol of the skull and crossbones. As a representative of the sellers of these products, Cun ningham feels that cer tification will be beneficial in the long run. “The full-time fanner is in business to feed people and make money, not kill his crop,” he states. “It’ll make him more aware of potential dangers.” “And what it will also do is to keep the average home owner, or the guy with a few acres of corn, from buying toxic compounds. That’s who is most likely to not read the label and adhere to usage directions - and end up getting himself in trouble,” concluded Cunningham. 19
