CARE OF GUIDE BAR
Uneven bar wear causes most guide bar problems.
Incorrect shaq)ening of chain cutter and depth gauge
settings often cause this. When bar wears unevenly,
it widens guide bar groove (see Figure 16). This
causes chain clatter and rivet popping. Saw will not
cut straight. Replace guide bar if this occurs.
Inspect guide bgu belbre shaq)ening chain. A worn or
dgunaged guide bar is unsafe. A worn or damaged guide
bgu will dgunage chain. It will also make cutting harder.

into wood and cutting creates only sawdust with few
large chips, chain is dull.
