OPERATION

nFelling Backcut. The backcut is always made level and horizontal, and at a minimum of 2 in. above the horizontal cut of the notch. See Figures 14 - 15.

nNever cut through to the notch. Always leave a band of wood between the notch and backcut (approximately 2 in. or 1/10 the diameter of the tree). This is called "hinge" or “hingewood.” It controls the fall of the tree and prevents slipping or twisting or shoot-back of the tree off the stump.

See Figures 14 - 15.

nOn large diameter trees, stop the back cut before it is deep enough for the tree to either fall or settle back on the stump. Then insert soft wooden or plastic wedges into the cut so they do not touch the chain. The wedges can be driven in, little by little, to help jack the tree over.

See Figure 16.

NOTE: When bucking or felling with a wedge, it may be necessary to remove the SAFE-T-TIP®anti-kickback device to allow the bar to be drawn through the cut. After the cut is complete, the tip should be reinstalled immediately.

nAs tree starts to fall, stop the chain saw by releasing the switch trigger and put it down immediately. Retreat along the cleared path, but watch the action in case something falls your way. Be alert for overhead limbs or branches that may fall and watch your footing.

WARNING:

Never cut through to the notch when making a backcut. The hinge controls the fall of the tree, this is the section of wood between the notch and backcut.

BUCKING

See Figures 17 - 20.

Bucking is the term used for cutting a fallen tree to the de- sired log length.

nAlways make sure your footing is secure and your weight is distributed evenly on both feet.

nCut only one log at a time.

nSupport small logs on a saw horse or another log while bucking.

nKeep a clear cutting area. Make sure that no objects can contact the guide bar nose and chain during cutting, this can cause kickback. To avoid the danger, keep the SAFE- T-TIP®anti-kickback device attached while cutting. Refer to “Kickback” earlier in this manual.

nWhen bucking on a slope, always stand on the uphill side of the log. To maintain complete control of the chain saw when cutting through the log, release the cutting pressure near the end of the cut without relaxing your grip on the chain saw handles. Do not let the chain contact the ground. After completing the cut, wait for the saw chain to stop before you move the chain saw. Always stop the motor before moving from tree to tree.

nSometimes it is impossible to avoid pinching (with just standard cutting techniques) or difficult to predict which way a log will settle when cut. To avoid pinching while cutting, rotate or move the log so that the pinch is elimi- nated.
