► Remove the resulting 45° piece. The size of
the wedge will vary by tree size. The larger the
tree, the larger the wedge. This model chain

Open-faced Notch
For an open-faced notch:

► The felling notch determines the direction of
the tree's fall. Make the felling notch perpen‐
dicular to the line of fall you have determined,
close to the ground.
► Be aware of conditions such as wind, limb and
foliage structure, tree lean, slope of the terrain
and other factors that could alter the direction
of fall.
► Cut down at a 50° angle to a depth of approxi‐
mately 1/5 to 1/4 of the trunk diameter.
► Make a second cut that meets the bottom of
the first cut from below at a 40° angle.
► Remove the resulting 90° piece. The size of
the wedge will vary by tree size. The larger the
tree, the larger the wedge. This model chain
saw is not intended for felling large diameter
trees.

Sapwood Cuts
Sapwood cuts help prevent soft woods in sum‐
mer from splintering when they fall:
► Make cuts at both sides of the trunk, at the

back cut. The hinge helps control the fall of the
tree. Cutting through the hinge will eliminate
the feller's ability to control the tree's fall and
may result in serious or fatal personal injury or
property damage.
never stand directly behind the tree when it is
about to fall, since part of the trunk may split
and come back towards the operator (barber-
chairing), or the tree may jump backwards off
the stump.
When the tree starts to fall, withdraw the bar,
release the trigger switch, engage the chain
brake and walk away briskly on the pre-plan‐
ned escape path.
When the tree hangs or for some other reason
does not fall completely, set the saw aside and
pull the tree to the ground with a cable winch,
block and tackle or tractor. Trying to cut it
down with your saw is extremely dangerous
and may result in serious or fatal injury. Trees
of this nature can fall suddenly and often are
under tension.
