The Saw Chain is one of the most common replacement parts on a chain saw or pole saw as its location causes it to be exposed to heat, dirt, and debris which cause it to grow dull with extended use. Never continue working with the chain until it is completely dull, a chain file used at regular intervals can quickly restore sharpness. When selecting a new saw chain, make sure you consider which is the right type for the jobs you plan to undertake, such as a low profile, narrow kerf, or ripping chain.
