Guide bar
Turn the guide bar once in a while to avoid wearing it out on one side.
The guide track on the guide bar should have straight edges. Check for wear: Press a ruler
against the guide bar and up against the outside of a guide link. If a gap between them is seen
then the guide bar is good. If no gap is seen then the guide track is worn and the guide bar must
be changed.
