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
vertically with your body. If the saw should kick-
back, 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
bucking operations.
Keep both hands on the handles at all times.
Support 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.
DANGER
• 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
agencies have attempted to prescribe
various safety devices, but the best
protection is to avoid kickback.
• Comply with the safety precautions as
listed in this Manual and Safety Manual.
