7 Proper Techniques for Basic Bucking, Limbing, Pruning and Felling
– When felling on a slope, the operator should stand
on the uphill side if possible.
When felling:
1
► Maintain a distance of at least 2 1/2 tree lengths from the
nearest person or structure.
► Take extra precautions in the vicinity of roads, railways
and power lines. Inform the police, utility company or
railway authority before beginning to cut.
7.5.2 Escape Path
Before making your first cut, prepare an escape path:
► First clear limbs and brush from the area around the base
of the tree. Remove vegetation from the lower portion of
the tree with an axe.

► Next, establish at least two clear paths of escape (B) and
remove any obstacles such as brush, small trees and
other vegetation. These paths should lead away from the
planned direction of the tree's fall (A) at a 45° angle from
the expected fall line. Place all tools and equipment a safe
distance away from the tree, but not on the escape paths.
7.5.3 Conventional Notch
For a conventional notch:
C
► The felling notch determines the direction of the tree's fall.
Make the felling notch perpendicular to the line of fall you
have determined, close to the ground.
► Be aware of conditions such as wind, limb and foliage
structure, tree lean, the slope of the terrain and other
factors that could alter the direction of fall.
► Cut down at a 45° angle to a depth of approximately 1/5 to
1/4 of the trunk diameter.
► Make a horizontal cut that meets the bottom of the first cut.
► Remove the resulting 45° piece. The size of the wedge will
vary by tree size. The larger the tree, the larger the wedge.
