Keep in mind that the wood is heavy
and that it will bend and pinch the
saw if improperly supported. The
trunk will weaken at the point where
you make the cut unless the tree is
lying on perfectly flat ground or
supported as shown. If you make the
cut with the tree on the ground, don’t
let the saw’s chain dig into the earth;
it is harmful for the saw, and you
stand a good chance of being struck
by flying debris.
To cut the trunk, use the bucking and two-cut sequence shown. The first cut
should be no deeper than one-third the trunk diameter.
Chain And Guide Bar Combination
The following combinations are recommended for model CS-501P.
Use of replacement saw chain and/or guide bar other than that
specified, or operation without the optional Kick Guard
TM
in
place, may cause severe kickback resulting in serious injury.
Only use saw chain designated as, “LOW-KICKBACK,” that
meets ANSI B175.1 or CSA Z62.1, .3 Standard when tested on
the representative sample of chain saws below 3.8 C.I.D., and
Echo guide bar specified.
Chain and guide bar gauge size must be identical. Use Bar/Chain
combinations shown in table above.
