Removing Buttress Roots; Bucking; Bucking With A Wedge - Ryobi RY10519A Operator's Manual

REMOVING BUTTRESS ROOTS

See Figure 25.
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
as stated in Proper Procedure For Tree Felling
after you have removed the large buttress roots.

BUCKING

See Figure 26.
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 SAFE-T-TIP
anti-kickback device attached while cutting.
Refer to Kickback in the Specific Safety Rules
section of this manual for more information.
 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 dif-
ficult to predict which way a log will settle when
cut.

BUCKING WITH A WEDGE

See Figure 27.
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 SAFE-T-TIP
device to allow the bar to be drawn through the
cut. After you complete the cut, reinstall the tip.
