Don’t cut with the saw overhead or the bar in a vertical position. If the
saw should kick back you may not have good enough control to pre-
vent possible injury.
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.

WARNING
DANGER
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 agencies have
attempted to prescribe various safety devices, but the best pro-
tection is to avoid kickback.
Comply with the Safety Precautions as listed on page 2 and 3 of
this manual.
DON’T cut with saw overhead!
Cutting, continued
