OPERATION
REMOVING BUTTRESS ROOTS
See Figure 34.
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. Refer to “Operation – Proper Procedure for Tree Felling” earlier in this manual.
BUCKING
See Figure 35.
Bucking is the term used for cutting a fallen 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. To avoid the danger, keep the
■During bucking operations, stand on the uphill side so that the
■ 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 36.
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.
Note: When bucking or felling with a wedge, you may need to remove the
