C. BUCKING Bucking is the term used for cutting a fallen tree to the desired log size. I. IMPORTANT POINTS a. Cut only one log at a time. b. Cut shattered wood very carefully Sharp pieces ofwood could be flungtoward the operator. c. Use a sawhorseto cut smalllogs.Neverallow another person to hold the log while cutting and never hold the log with your leg or foot. d. Do not cut in an area where logs, limbs, and roots are tangled such as in a blown down area. Drag the logs into a clear area before cutting by pulling out exposed and cleared logs fast. e. Make the first bucking cut 1/3 of the way through the log and finish with a2/3 cut on the opposite side. As the logis beingcut, it will tend to bend. The saw can become pinched or hung in the log if you make the first cut deeper than 1/3 of the diameter of the log. f. Give special attention to logs under strain to prevent the saw from pinching. Make the first cut on the pressure side to relieve the stress on the log. Figure 21 . 2. TYPES OF CUFFING USED (Figure 22): Overcutting - begin on the top side of the log with the bottom of the saw against the log-, exert light pressure downward. -- Undercutting - begin on the under side of the log with the top of the saw against the log; exert light pressure upward. During undercutting, the sawwill tend topush backatyou. Be prepared for this reaction and hold the saw firmly to maintain control. A WARNING Never turn the saw upside down to undercut. The saw cannot be controlled in this position. A WARNING If saw becomes pinched or hung in a log, don't try to force it out. You can lose control of the saw resulting in injury and/or damage to the saw. Stop the saw, drive a wedge of plastw or wood into the cut until the sawcan beremoved easilyFigure 23 . Restart the saw and carefully reenter the cut. To avoid kickback and chain damage, do not use a metal wedge. Do not attempt to restart your saw when'it is pinched or hung in a log. 3.

and
finish
with
a2/3
cut
on

As
the
log
is
being
