CAUTION
Wear suitable hearing protective device such as
earmuffs or earplugs to protect against
objectionable or uncomfortable loud noises.
Don’t cut with the saw overhead or the bar in a
vertical position. If the saw should kick back, you
may not have well 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.
WARNING 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 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 ON PAGE 1 OF THIS MANUAL
AND SAFETY MANUAL.
