- Page 6 SAFETY INFORMATION KICKBACK (See Figure 1-2) W A R N I N G Kickback may occur when the moving chain contacts an object at the upper portion of the tip of the guide bar or when the wood closes in and pinches the saw chain in the cut. Contact at the upper portion of the tip of the guide bar can cause the chain to dig into the object and stop the chain for an instant.
- Page 7 SAFETY INFORMATION • Push and Pull - This reaction force is always opposite to the direction the chain is moving where wood contact is made. Thus, the operator must be ready to control the PULL when cutting on the bottom edge of the bar, and PUSH when cutting along the top edge. (See Figure 3) PULL PUSH...

Page 20: Felling Trees
OPERATING YOUR CHAIN SAW FELLING TREES HAZARDOUS CONDITIONS W A R N I N G Do not fell trees during periods of high wind or heavy precipitation. Wait until the hazardous weather has ended. When felling a tree, it is important that you heed the following warnings to prevent possible serious injury. - 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.
- Page 23 OPERATING YOUR CHAIN SAW (See Figure 16) REMOVING BUTTRESS ROOTS A buttress root is a large root extending from the trunk of the tree above the ground. Remove vertical cut. Remove the resulting loose section from the work area. Follow the correct tree felling procedure as stated in Proper Procedure For Tree Felling after you have removed the large buttress roots.
- Page 24 OPERATING YOUR CHAIN SAW (See Figure 18) BUCKING WITH A WEDGE 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. (See Figure 19) BUCKING LOGS UNDER STRESS side.
- Page 25 OPERATING YOUR CHAIN SAW LIMBING (See Figure 22) Limbing is removing branches from a fallen tree. • Work 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. •...
- Page 26 OPERATING YOUR CHAIN SAW CUTTING SPRINGPOLES (See Figure 24) A springpole is any log, branch, rooted stump, or sapling which is bent under tension by other wood so that it springs back if the wood holding it is cut or removed. On a fallen tree, a rooted stump has a high potential of springing back to the upright position during the bucking cut to separate the log from the stump.
