Continued
6. When stal_ing a cut, place moving chain against
wood. Hold saw firmly in place to avoid possible
bouncing or skating (sideways movement) of saw.
7. Guide saw using light pressure. Do not force
saw. The motor will overload and can burn out.
It will do the job better and safer at the rote for
which it was intended.
8. Remove saw fiom a cut with saw running at full
speed. Stop saw by releasing trigger. Make sure
chain has stopped before setting saw down.
9. Practice until you can maintain a steady, even
cutting rate.

(Cutting
Down
a Tree)
_WARNING:
• Avoid kickback.
Kickbackcan
result in
severe injury or death. See Kickback,
page 3, to avoid risk of kickback.
• Do not fell a tree without ample skill or
expert help.
• Keep children,animNs,
and bystanders
away from area when felling a tree.
• If two or more persons perform buck-
ing and felling operations at the same
time, provide ample distance
between
operations. Provide distance of at least
twice the height of tree being felled.
d_k WARNING: When felling atree, be aware
of yoursurroundings.
Do not endangerany
person, strike utility lines, orcause property
damage, if tree strikes utility lines, contact
utility company at once.
Felling is the process of cutting down a tree. Make
sure your footing is firm. Keep feet apart. Divide
your weight evenly on both feet. Follow directions
below to fell a tree.
Before
Felling
a Tree
1. Before felling, inspect tree. Make sure there are
no dead limbs or branches that may fall on you.
Study natural lean of tree, location of larger
branches, and wind direction. This will help you
judge which way tree will fall.
2. Clear work area around tree.
3. Plan and clear a retreat path before felling. Make
retreat path opposite to planned direction of fall
of tree and at 45 ° angle (see Figure 10).
4. Remove dill, stones, loose bark, nails, staples, and
wire from tree where you will make felling cuts.
5. Stay on uphill side when felling tree. Tree could
roll or slide downhill after falling.
Felling
Procedure
A) Felling
Notch
A properly placed felling notch will determine direc-
tion tree will fall. Place telling notch on side of tree in
direction you want tree to fall (see Figure 11). Follow
directions below to create a telling notch.
1. Make lower notch cut as close to ground as pos-
sible. Hold saw so guide bar is horizontal. Cut
1/3 the diameter of tree trunk (see Figure l l).
Note: Always make this horizontal lower notch
cut first. If you make this cut second, tree can
pinch chain or guide bar.
2. Stal_ upper notch cut the same distance above
first cut as first cut is deep.
Example: If lower notch cut is eight inches deep,
start upper notch cut eight inches above it. Cut
downward at 45 °angle. The uppernotch cut should
meet end of lower notch cut (see Figure 1l).
3. Remove tree trunk wedge created by notching cuts.
B) geIHng
Cut
1. Make telling cut two inches higher than lower
notch cut and on opposite side of tree (see Figure
11). Keep telling cut parallel to lower notch cut.
2. Cut towards notch.
_,
WARNING:
Do not cut all the way
through
tree. Leave about two inches
of tree diameter
uncut directly
behind
felling
notch (see Figure 11).This uncut
portion acts as a hinge.The
hinge helps
keep tree from twisting
and falling
in
wrong direction.
3.
As Mling cut negus Nnge, tree should begin to falL
Note: If needed, drive wedges into telling cut to
control direction of fall. If tree settles back and
pinches chain, drive wedges into telling cut to re-
move saw. Only use wedges made of wood, plastic,
or aluminum. Never use wedge made of steal. This
could cause kickback and damage to chain.
4.
When tree begins to fall quickly
• remove saw from telling cut
• release trigger to turn saw off
• put saw down
• exit area using retreat path
_lb WARNING: Be alert for falling
over=
head limbs. Watch your
footing
while
exiting area.
