SOME GOOD SAW CHAIN ADVICE
1. Saw chain is made to cut only one thing: wood. Do not use saw
chain to cut other materials, and never let your chain contact rocks
or dirt during operation. Dirt may seem soft. But, in fact, dirt is
extremely abrasive and will wear away your chain's vital chrome
plating within seconds.
2. Never force dull chain to cut. When it is sharp, saw chain is
designed to feed itself into the wood, and needs only light pressure
to cut efficiently. Dullness, or sharpness, is also indicated by the
sawdust your chain is producing. Dull chain produces fine wood
dust, which can clog your saw's air filter. Sharp chain produces
wood chips.
