C.BUCKING
Bucking is the term used for cutting a fallen tree to the desired log size.
1.IMPORTANT POINTS
a. Cut only one log at a time.
b.Cut shattered wood very carefully. Sharp pieces of wood could be flung toward the operator
c.Use a sawhorse to cut small togs. Never allow another person to hold the log while cut- ting and never hold the logwith your leg or foot
d.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 20.
e.Do not cut in an area where logs, limbs and
roots are tangled such as in a blown down area. Pullout exposed and cleared logsfirst.Drag
the logsinto a clear area before cutting.
f, Make the first bucking cut 1/3 of the way through the log and finish with a 2/3 cut on the opposite side. As the log is being cut, itwill 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 fo the log.
. TYPES OF cu'n'ING USED Figure 21.
Undercutting - begin on the underside of the !og with the spur against the log; exert light pressure upward. During undercutting,the saw willtend to push backat you.Be preparedfor this reactionand 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.
,_ WARNING
if saw becomes pinched or hung in a log, don'ttry 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 plastic or wood into the cut until the saw can be removed easily. Figure 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.BUCKING m WITHOUT A SUPPORT a. Overcut with a 1/3 diameter cut.
b, Roll log over and finishwith an overcut.
