How to con
fi
rm:
1)
Turn
o
ff
the
engine.
2)
Holding
the
chain
saw
horizontally,
release
your
hand
from
the
front
handle,
hit
the
tip
of
the
guide
bar
to
a
stump
or
a
piece
of
wood,
and
con
fi
rm
brake
operation.
Operating
level
varies
by
bar
size.
In
case
the
brake
is
not
e
ff
ective,
ask
our
dealer
for
inspection
and
repairs.
If
the
engine
keeps
rotating
at
high
speed
with
the
brake
engaged,
the
clutch
will
overheat
causing
trouble.
When
the
brake
engages
during
operation,
immediately
release
the
throttle
trigger
to
stop
the
engine.
WARNING
Do
not
carry
the
machine
with
the
engine
running.
Stopping (Fig. 18)
Decrease
engine
speed,
and
push
ignition
switch
(16)
to
stop
position.
WARNING
○
Do
not
overreach
or
cut
above
shoulder
height.
○
Use
extra
caution
when
felling,
and
do
not
use
the
saw
in
a
nose-
high
position
or
above
shoulder
height.
CHAIN CATCHER
The
chain
catcher
is
located
on
the
power
head
just
below
the
chain
to
further
prevent
the
possibility
of
a
broken
chain
striking
the
chain
saw
user.
WARNING
Do
not
stand
in-line
with
chain
when
cutting.
BASIC
TECHNIQUES
FOR
MAKING
FELLING,
LIMBING
AND
BUCKING
CUTS
The
intention
of
the
following
information
is
to
provide
you
with
the
general
introduction
to
wood
cutting
techniques.
WARNING
○
This
information
does
not
cover
all
speci
fi
c
situations,
which
may
depend
on
di
ff
erences
in
terrain,
vegetation,
kind
of
wood,
form
and
size
of
trees,
etc.
Consult
your
servicing
dealer,
forestry
agent
or
local
forestry
schools
for
advice
on
speci
fi
c
woodcutting
problems
in
your
area.
This
will
make
your
work
more
e
ffi
cient
and
safer.
○
Avoid
cutting
in
adverse
weather
conditions,
such
as
dense
fog,
heavy
rain,
bitter
cold,
high
winds,
etc.
Adverse
weather
is
often
tiring
to
work
in
and
creates
potentially
dangerous
conditions
such
as
slippery
ground.
High
winds
may
force
the
tree
to
fall
in
an
unexpected
direction
causing
property
damage
or
personal
injury.
CAUTION
Never
use
a
chain
saw
to
pry
or
for
any
purpose
for
which
it
is
not
intended.
WARNING
○
Avoid
stumbling
on
obstacles
such
as
stumps,
roots,
rocks,
branches
and
fallen
trees.
Watch
out
for
holes
and
ditches.
Be
extremely
cautious
when
working
on
slopes
or
uneven
ground.
Shut
o
ff
the
saw
when
moving
from
one
work
place
to
another.
Always
cut
at
wide
open
throttle.
A
slow
moving
chain
can
easily
catch
and
force
the
saw
to
jerk.
○
Never
use
the
saw
with
only
one
hand.
You
cannot
control
the
saw
properly
and
you
may
lose
control
and
injure
yourself
severely.
Keep
the
saw
body
close
to
your
body
to
improve
control
and
reduce
strain.
When
cutting
with
the
bottom
part
of
the
chain
the
reactive
force
will
pull
the
saw
away
from
you
towards
the
wood
you
are
cutting.
The
saw
will
control
the
feeding
speed
and
sawdust
will
be
directed
towards
you.
(
Fig. 19
)
○
When
cutting
with
the
upper
part
of
the
chain
the
reactive
force
will
push
the
saw
towards
you
and
away
from
the
wood
you
are
cutting.
(
Fig. 20
)
○
There
is
a
risk
of
kickback
if
the
saw
is
pushed
far
enough
so
that
you
begin
to
cut
with
the
nose
of
the
bar.
The
safest
cutting
method
is
to
cut
with
the
bottom
part
of
the
chain.
Sawing
with
the
upper
part
makes
it
much
more
di
ffi
cult
to
control
the
saw
and
increases
the
risk
of
kickback.
○
In
case
the
chain
locked,
immediately
release
the
throttle
trigger.
If
the
throttle
trigger
keeps
rotating
at
high
speed
with
the
chain
locked,
the
clutch
will
overheat
causing
trouble.
NOTE
Always
keep
the
spiked
bumper
face
to
a
tree,
because
the
chain
may
suddenly
be
drawn
into
a
tree.
FELLING
Felling
is
more
than
cutting
down
a
tree.
You
must
also
bring
it
down
as
near
to
an
intended
place
as
possible
without
damaging
the
tree
or
anything
else.
Before
felling
a
tree,
carefully
consider
all
conditions
which
may
e
ff
ect
the
intended
direction,
such
as:
Angle
of
the
tree.
Shape
of
the
crown.
Snow
load
on
the
crown.
Wind
conditions.
Obstacles
within
tree
range
(e.g.,
other
trees,
power
lines,
roads,
buildings,
etc.).
WARNING
○
Always
observe
the
general
conditions
of
the
tree.
Look
for
decay
and
rot
in
the
trunk
which
will
make
it
more
likely
to
snap
and
start
to
fall
before
you
expect
it.
Look
for
dry
branches,
which
may
break
and
hit
you
when
you
are
working.
○
Always
keep
animals
and
people
at
least
twice
the
tree
length
away
while
felling.
Clear
away
shrubs
and
branches
from
around
the
tree.
Prepare
a
path
of
retreat
away
from
the
felling
direction.
BASIC RULES FOR FELLING TREES
Normally
the
felling
consists
of
two
main
cutting
operations,
notching
and
making
the
felling
cut.
Start
making
the
upper
notch
cut
on
the
side
of
the
tree
facing
the
feeling
direction.
Look
through
the
kerf
as
you
saw
the
lower
cut
so
you
do
not
saw
too
deep
into
the
trunk.
The
notch
should
be
deep
enough
to
create
a
hinge
of
su
ffi
cient
width
and
strength.
The
notch
opening
should
be
wide
enough
to
direct
the
fall
of
the
tree
as
long
as
possible.
Saw
the
felling
cut
from
the
other
side
of
the
tree
between
one
and
two
inches
(3–5
cm)
above
the
edge
of
the
notch.

)

minimum

Hinge
24.
Felling
cut
Never
saw
completely
through
the
trunk.
Always
leave
a
hinge.
The
hinge
guides
the
tree.
If
the
trunk
is
completely
cut
through,
you
lose
control
over
the
felling
direction.
Insert
a
wedge
or
a
felling
lever
in
the
cut
well
before
the
tree
becomes
unstable
and
starts
to
move.
This
will
prevent
the
guide
bar
from
binding
in
the
felling
cut
if
you
have
misjudged
the
falling
direction.
Make
sure
no
people
have
come
into
the
range
of
the
falling
tree
before
you
push
it
over.
FELLING CUT, TRUNK DIAMETER MORE THAN TWICE GUIDE
BAR LENGTH
Cut
a
large,
wide
notch.
Then
cut
a
recess
into
the
center
of
the
notch.
Always
leave
a
hinge
on
both
sides
of
the
center
cut.
(
Fig. 22
)
Complete
the
felling
cut
by
sawing
around
the
trunk
as
in
the
Fig. 23
.
WARNING
These
methods
are
extremely
dangerous
because
they
involve
the
use
of
the
nose
of
guide
bar
and
can
result
in
kickback.
Only
properly
trained
professionals
should
attempt
these
techniques.
LIMBING
Limbing
is
removing
the
branches
from
a
feller
tree.
