Saw Chain
To keep your cutting system of chain, bar, and
sprocket working at peak efficiency - and to minimize
wear - there are a number of things every user should
do periodically. There are specific maintenance tasks
that should be performed and there are more general
“common-sense” things to do, some of which need to
occur with greater frequency, some with lesser frequen-
cy. And there are some things you should never do.
To help you know what to do and how often, Oregon
®
uses five symbols that tell the frequency at which each
of the different activities should occur. Here are the five
symbols, what they mean, and an example of a task or
activity that corresponds to each.
