Chain Speed
« on: April 10, 2017, 07:05:16 PM »
Howdy Folks:

I have an almost new Stihl MS250 with a factory 20 inch bar and chain.  With the engine not under load and at WOT how many times would a tooth pass a certain point on the bar in a given time period?

I work in a (gulp) big box store and we sell a lot of chainsaws to one time or causal user type people, however, we sell very few safety items such as chainsaw helmets or chaps.  If I could educate our employees and customers it could save a life.

God Bless, Ward and Mary.

Dull chains cause accidents.  Accidents cause shorter life spans.
You don't sharpen a chain when it gets dull.  You sharpen a chain to keep it from getting dull.

Roughly, the chain travels at 88 FPS when engine RPM is 12k. So, if your chain is 48" long, 1 tooth should travel 22 rotations in a second.

I believe that the MS 250 is a class 1 saw that means 20-22m/s chain speed. So simply put for each second the chains bite into your leg it moves 20m(60 feet).
That means on a 16" chain it has the ability to (in theory) to cut 15-16" deep each second so two- three seconds at the most for a leg.
In Denmark the biggest problem is also to get Mr and Mrs. Denmark to buy safety gear and not think as a chain saw is a toy og just a fancy hand saw.
