LIMBING
Limbing a fallen tree is much the same as bucking.
Never stand on the tree that you are limbing.
When limbing, caution is the word.
Be careful of the tip touching other limbs.
Always use both hands.
Don’t cut with the saw overhead or aligned vertical
-
ly with your body. If the saw should kickback, you
may not have enough control to prevent possible
injury.
BUCKING
Bucking is the sawing of a log or fallen tree into
smaller pieces.
There are a few basic rules which apply to all buck
-
ing operations.
Keep both hands on the handles at all times. Sup-
port logs if possible.
When cutting on a slope or hillside, always stand
uphill.
Keep in mind that the wood is heavy and that it will
bend and pinch the saw if improperly supported.
The trunk will weaken at the point where you make
the cut unless the tree is lying on perfectly flat
ground or supported as shown.
If you make the cut with the tree on the ground,
don’t let the saw’s chain dig into the earth; it is
harmful for the saw, and you stand a good chance
of being struck by flying debris.
To cut the trunk, use the bucking and two-cut
sequence shown.
The first cut should be no deeper than one-third
the trunk diameter.
WARNING
KICKBACK IS DANGEROUS
Kickback is generated when the rotation of the
chain is arrested for some reason. The most
dangerous effect of this action occurs when the
nose of the bar contacts another object, the chain
is momentarily stopped and all the energy of the
engine throws the bar upwards and backwards
towards the operator.
The chain saw industry and government agen
-
cies have attempted to prescribe various safety
devices, but the best protection is to avoid kick-
back.
Comply with the Safety Precautions as listed in
this manual.
