1. Make first cut on underside of log (see
Figure 15). Use top of guide bar to
make this cut. Cut 1/3 through diam-
eter of log. This cut will keep section
from splintering when cut.
2. Make second cut directly above first
cut. Cut down to meet first cut. This
cut will keep log from pinching guide
bar and chain.

Keep saw body clean. Use a soft cloth damp-
ened with a mild soap and water mixture.
Wipe saw body to clean.
CARE OF GUIDE BAR
Uneven bar wear causes most guide bar prob-
lems. Incorrect sharpening of chain cutter 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.
