6. Reset the spiked bumper at a low point when
cutting thicker logs by pulling the product slightly
backwards until the gripping teeth release, and
reposition at lower level to continue sawing. Do not
remove the product completely from the wood.
7. Do not force the saw chain while cutting, let the
chain do the work, using the gripping teeth of
spiked bumper to apply minimal leverage pressure.
8. Do not operate the product with arms fully extended
or attempt to saw areas which are difficult to reach,
or on a ladder. Never use the product above
shoulder height.
9. Optimum sawing is achieved if the chain speed
remains constant during cutting.
10. Be careful when reaching the end of the cut. The
weight of the product may change unexpectedly as
it cuts free from the wood. This can cause accidents
to the legs and feet. Always remove the product
from a wood cut while the product is running.
11. Check the chain tension and oil feeding regularly.
Most 'kickback' accidents happen during limbing! Pay
close attention to the position of the 'kickback' zone of
the bar when you are 'limbing' branches that are under
tension.
1. When bucking and felling operations are being
performed by two or more persons at the same
time, the felling operations should be separated
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 does make contact
with any utility line, the utility company should be
notified immediately.
2. The product operator should keep on the uphill
side of the terrain as the tree is likely to roll or slide
downhill after it is felled.
3. An escape path should be planned and cleared as
necessary before cuts are started. The escape path
should extend back and diagonally to the rear of the
expected line of fall(Fig.20).

4. 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.
5. Remove dirt, stones, loose bark, nails, staples and
wire from the tree.
Make the notch (B) 1/3 the diameter of the tree,
perpendicular to the direction of falls. Make the lower
horizontal notching cut first. This will help to avoid
pinching either the saw chain or the guide bar when the
second notch is being made.
Make the felling back cut (A) at least 1.97in.(5 cm )
higher than the horizontal notching cut. Keep the felling
back cut parallel to the horizontal notching cut. Make
the felling back cut so enough wood is left to act as a
hinge. The hinge (C) wood keeps the tree from twisting
and falling in the wrong direction. Do not cut through the
hinge.
As the felling gets close to the hinge, the tree should
begin to fall. If there is any chance that the tree may
not fall in desired direction or it may rock back and bind
the saw chain, stop cutting before the felling back cut is
complete and use wedges of wood, plastic or aluminum
to open the cut and drop the tree along the desired line
of fall.
When the tree begins to fall remove the chainsaw from
the cut, stop the engine put the chainsaw down then
use the retreat path planned. Be alert for overhead
limbs falling and watch your footing(Fig.21).
