Cutting Instructions - EarthWise CS30116 Manual Del Operador

As the tree starts to fall, stop the chain saw and put it down
immediately. Retreat along the cleared path, but watch the action
in case something falls your way. Be alert for overhead limbs or
branches that may fall and watch your footing.
WARNING: Never cut through to the notch when making a
back-cut. The hinge controls the fall of the tree, this is a section
of wood between the notch and back-cut.
Bucking is the term used for cutting a fallen tree to the desired log
length.
Always make sure your footing is secure and your weight is
distributed evenly on both feet.
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 kick-
back.
When bucking on a slope, always stand on the uphill side of the
log. To maintain complete control of the chain saw when cutting
through the log, release the cutting pressure near the end of the
cut without relaxing your grip on the chain saw handles. Do not let
the chain contact the ground. After completing the cut, wait for the
saw chain to stop before you move the chain saw. Always stop the
motor before moving from tree to tree.
BUCKING LOGS UNDER STRESS
When the log is supported along its entire length, it should be cut
from the top or over-bucking.
When the log is supported on one end, cut 1/3 diameter from the
underside or under-bucking. Then make the finishing cut by over-
bucking to meet the first cut.
As the log is being cut, it will tend to bend. The saw can become
pinched or hung in the log if you make the first cut deeper than 1/3
of the diameter of the log.
Give special attention to logs under stress to prevent the bar and
chain from pinching.
OVERBUCKING – Begin on the top side of the log with the bottom
of the saw against the log; exert light pressure downward. Note
that the saw will tend to pull away from you.
UNDER-BUCKING – Begin on the under side of the log with the
top of the saw against the log; exert light pressure upward. During
under-bucking, the saw will tend to push back at you. Be prepared
for this reaction and hold the saw firmly to maintain control.

LIMBING
Limbing is removing branches from a fallen tree.
Work slowly, keeping both hands on the chain saw with a firm
grip. Always make sure your footing is secure and your weight is
distributed evenly on both feet.
Leave the larger support limbs under the tree to keep the tree off the
ground while cutting.
Limbs should be cut one at a time. Remove the cut limbs from the
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 cutting.
WARNING: Never climb into a tree to limb or prune. Do not stand on
ladders, platforms, a log, or in any position which can cause you to
lose your balance or control of the saw.
CUT LIMBS ONE AT A TIME AND LEAVE
SUPPORT LIMBS UNDER TREE UNTIL

PRUNING
Pruning is trimming limbs from a live tree.
Work slowly, keeping both hands on the chain saw with a firm
grip. Always make sure your footing is secure and your weight is
distributed evenly on both feet.
When pruning trees it is important not to make the finishing cut next
to the main limb or trunk until you have cut off the limb further out to
reduce the weight. This prevents stripping the bark from the main
member.
Under-buck the branch 1/3 through for your first cut.
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.
WARNING: SPRINGPOLES
A springpole is any log, branch, rooted stump, or sapling which is
bent under tension by other wood so that 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.
