  • Page 21 OPERATING YOUR CHAIN SAW PROPER PROCEDURE FOR TREE FELLING (See Figure 12-15) ‡ Felling a tree — When bucking and felling operations are being performed by two or more persons, at the same time, the felling operation should be separated from the bucking operation by a distance of at least twice the height of the tree being felled.
  • Page 22 OPERATING YOUR CHAIN SAW NOTE: Never cut through to the notch. Always leave a band of wood between the notch and back cut (ap- proximately 2" (5 cm) 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.
