OREGON® CHAIN SAW
MODEL CS1500-091
• 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 18)

• After most of the limb has been removed,
make one smooth cut near the trunk

OPERATING THE CHAIN 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. 20).

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
