Operating the Chainsaw
Chainsaw Model CS1200-091
• Thick limbs (greater than cm ( inch) 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 (),
then cut the limb all of the way through from
the top of the limb () to match the bottom
cut (Fig. ).
• After most of the limb has been removed,
make one smooth cut near the trunk (Fig. ).
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. 10).
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.
