Stihl is a German company that produces a line of chain saws. The chain saws are almost universal among major tree-trimming and wood-cutting companies and are also favored by farmers, ranchers and homeowners who want a rugged, reliable saw that starts easily and can handle almost any cutting task. Discontinued models include the 015AV.
Out of Style But Still Popular
One saw you won't find today in Stihl's product line is the 015AV. It is still widely available through auctions and garage sales and is something of a collector's item. Stihl's website doesn't even have a listing for the 015AV, although a product history does mention it. Stihl doesn't list an 015AV manual on its website but will send one to anyone who asks.
It Was a "Hobby" Saw
Stihl says it made the 015AV from 1973 to 1983. A Stihl product history says it was introduced in 1974 as a "chainsaw for do-it-yourself hobby users." It was a small saw, equipped with bars from 10 to 14 inches in cutting length. It had a single-cylinder, two-stroke engine, standard on Stihl chainsaws, with a piston displacement of 1.95 cubic inches and a cylinder bore of 1.5 inches. Stihl's MS170, today's most popular homeowner model, is roughly comparable, with a displacement of 1.84 cubic inches and bore of 1.46 inches.
Fairly Hefty Saw
The 015AV was fairly hefty, weighing 11.5 lbs. with a 12-inch bar and chain, 9.6 pounds with the powerhead only. That compares to the MS170 which weighs 8.6 lbs. without a bar and chain, which can vary from 12 to 16 inches with 14 inches the standard. All except the most powerful Stihl saws today are under 10 lbs., with powerhead only.
Most Features Were Standard Stihl
The 015AV had a fuel capacity of .7 pint, using a standard 1:40 blend of Stihl two-stroke engine oil and gasoline. The MS170 has a capacity of .53 pint with a 1:50 fuel mix but is recommended to use only 89 octane or higher gasoline, while the 015AV used regular gasoline. Most other elements of the 015AV were standard for Stihl saws: felt element air filter, carburetor with integrated fuel pump, automatic chain oiling with constant delivery, a chain brake to stop the chain in kickback situations, and a chain catcher to block any broken saw chain.
