this manual. Always include new drive

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 the bar wears
unevenly, it widens the guide bar groove
(See Fig. G). This causes chain clatter
and rivet popping. Saw will not cut
straight.
Replace guide bar if this occurs.
Inspect guide bar before sharpening
