CARE OF GUIDE BAR
Uneven bar wear causes most guide bar
problems. Incorrect sharpening of chain cut-
ter and depth gauge settings often cause this.
When bar wears unevenly, it widens guide
bar groove (see Figure 17). This causes
chain clatter and rivet popping. Saw will not
cut straight. Replace guide bar if this occurs.
Inspect guide bar before sharpening chain.
A worn or damaged guide bar is unsafe. A
worn or damaged guide bar will damage
chain. It will also make cutting harder.
