OPERATION
BUCKING WITH A WEDGE
See Figure 19.
If the wood diameter is large enough for you to insert a soft bucking wedge without touching the chain, you should use the wedge to hold the cut open to prevent pinching.
NOTE: When bucking or felling with a wedge, you may need to remove the
BUCKING LOGS UNDER STRESS
See Figure 20.
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 you cut the log, 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.
Give special attention to logs under stress to prevent the bar and chain from pinching.
OVERBUCKING
See Figure 21.
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.
UNDERBUCKING
See Figure 22.
Begin on the under side of the log with the top of the saw against the log; exert light pressure upward. During underbucking, the saw will tend to push back at you. Be prepared for this reaction and hold the saw firmly to maintain control.
LIMBING
See Figure 23.
Limbing is removing branches from a fallen tree.
nWork slowly, keeping both hands on the chain saw with a firm grip. Always make sure your footing is secure and your weight is distributed evenly on both feet.
nLeave the larger support limbs under the tree to keep the tree off the ground while cutting.
nLimbs should be cut one at a time. Remove the cut limbs from the work area often to help keep the work area clean and safe.
