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 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 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.

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.
