Felling A Tree - Oregon CS300 Manuel D'instruction

OREGON® Cordless Tool System
CHAIN SAW MODEL CS300
• Thick limbs (greater than 4 inch (10 cm)
in diameter) can splinter or pinch the
chain when making a single cut from
the top . To avoid pinching or splintering,
first make one shallow relief cut on the
bottom surface of the limb (1), then cut
the limb all of the way through from the
top of the limb (2) to match the bottom
cut (Fig . 31) .

• After most of the limb has been
removed, make one smooth cut near
the trunk (Fig . 32) .

OPERATING THE SAW

FELLING A TREE

CAUTION: A TREE IS LIKELY TO
ROLL OR SLIDE DOWNHILL AFTER IT
IS FELLED. Plan and clear a retreat path
before cuts are started. The retreat path
should extend back and diagonally to the rear
of the expected line of fall (Fig. 33).

RETREAT PATH
OPTIONS
DIRECTION
OF FALL
Felling is cutting down a tree .
• Before felling is started, consider the
natural lean of the tree, the location of
larger branches and the wind direction
to judge which way the tree will fall .
• Remove dirt, stones, loose bark, nails,
staples and wire from the tree where
felling cuts are to be made .
• When bucking and felling operations
are being performed by two or more
persons at the same time, separate
the felling operation from the bucking
operation by a distance of at least twice
the height of the tree being felled .
• Trees should not be felled in a manner
that would endanger any person, strike
any utility line or cause any property
damage . If the tree contacts any utility
line, immediately leave the area and
notify the utility company .
• Use the metal spikes on the front of the
saw to support the saw on the wood .
Set metal spiked bumper into the wood
and use as a leverage point to increase
stability when cutting large diameter
wood .
