OPERATION

BUCKING LOGS UNDER STRESS

Make the first bucking cut one-third of the way through the log and finish with a two-thirds cut on the opposite side. As you cut the log, it will tend to bend. The saw may become pinched or hung in the log if you make the first cut deeper than a third of the diameter of the log.

Give special attention to logs under stress to prevent the bar and chain from pinching.

OVER-BUCKING

See Figure 38.

Begin on the top side of the log with the bottom of the saw against the log; exert light pressure downward. Note that the saw will tend to pull away from you.

UNDER-BUCKING

See Figure 38.

Begin on the under side of the log with the top of the saw against the log; exert light pressure upwards. During under- bucking, the saw will tend to push back at you. Be prepared for this reaction and hold the saw firmly to maintain control.
