CARE OF GUIDE BAR
Uneven bar wear causes most guide bar problems.
Incorrect sharpening of chain cutter and depth
gauge settings often cause this. When bar wears
unevenly, it widens guide bar groove (see Figure
21). 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.
