into the cut so they do not touch the chain. Drive wedges in, little by little, to help
jack the tree over.
6. As the tree starts to fall, stop the chainsaw and put it down immediately. Retreat
along the cleared path, but watch the action in case something falls your way.
WARNING
Never cut through to the notch when making a back cut. The hinge controls the fall of
the tree; this is the section of wood between the notch and back cut.
REMOVING BUTTRESS ROOTS
See Figure 27.
A buttress root is a large root extending from the trunk of the tree above the ground.
Remove large buttress roots prior to felling. Make the horizontal cut into the buttress
first, followed by the vertical cut. Remove the resulting loose section from the work area.
Follow the correct tree felling procedure after you have removed the large buttress
roots.
BUCKING
See Figure 28.
Bucking is the term used for cutting a felled tree to the desired log length.
Cut only one log at a time.
Support small logs on a saw horse or another log while bucking.
Keep a clear cutting area. Make sure that no objects can contact the guide bar nose
and chain during cutting; this can cause kickback.
During bucking operations, stand on the uphill side so that the cut-off section of the
log cannot roll over you.
Sometimes it is impossible to avoid pinching (with just standard cutting techniques)
or difficult to predict which way a log will settle when cut.
BUCKING WITH A WEDGE
See Figure 29.
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.
