the ground while cutting.

work area often to help keep the work area clean and safe.
Branches under tension should be cut from the bottom up to aVOid
binding the chain saw.
Keep the tree between you and the chain saw while limbing. Cut
from the side of the tree oppOSite the branch you are cutiing.

main member.
Under-buck the branch

Your second cut should over-buck to drop the branch off.
Now make your finishing cut smoothly and neatly against the main
member so the bark will grow back to seal the wound.
SPRINGPOLES
A sprtngpole is any log. branch, rooted stump, or sapling which is
bent under tension by other wood so !hat it springs back if the
wood holding it is cut or removed. On
a
fallen tree, a rooted stump
has a high potential of springing back to the upright position during
the bucking
cut
to separate the log from the stump. Watch out for
springpoles, they are dangerous. They could result in severe or
fatal injury.
