UK - Page 20 FELLING TREES HAZARDOUS CONDITIONS See Figure 29. OPERA TION C W ARNING: Do NOT fell trees near power lines or near buildings which could be struck by falling limbs or the tree itself.
UK - Page 21 PLANNED PATH OF SAFE RETREAT 135° FROM PLANNED LINE OF FALL PLANNED LINE OF FALL Fig. 30 RETREAT PLANNED LINE OF FALL 45° 45° 90° 135° 135° RETREAT SAFE RETREAT ZONE 90° PROPER PROCEDURE FOR TREE FELLING See Figure 30. 1. Pick your escape route (or routes in case the intended route is blocked).
UK - Page 22 3. Cut a notch about one-third the diameter of the trunk in the side of the tree. Make the notch cuts so they intersect at right angles to the line of fall. This notch should be cleaned out to leave a straight line. To keep the weight of the wood off the saw, always make the lower cut of the notch before the upper cut.
UK - Page 23 REMOVING BUTTRESS ROOTS A buttress root is a large root extending from the trunk of the tree above the ground. Remove large buttress roots before felling. Make the horizontal cut into the buttress first, f ollowed b y the ver tical cut. Remove the resulting loose section from the work area.
UK - Page 24 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 sa w may become pinched or hung in the log if you make the first cut deeper than a third of the diameter of the log.
UK - Page 25 LIMBING AND PRUNING Q Work slowly, keeping both hands on the saw with a firm grip. Maintain secure footing and balance. Q Keep the tree between you and the chain while limbing. Cut from the side of the tree opposite the branch you are cutting.
