GENERAL SAFETY PRECAUTIONS
which stops the chain for an instant. The
result is a lightning fast, reverse reaction
which kicks the guide bar up and back to-
ward the operator.
S Pinch-Kickback can occur when the the
wood closes in and pinches the moving
saw chain in the cut along the top of the
guide bar and the saw chain is suddenly
stopped. This sudden stopping of the
chain results in a reversal of the chain
force used to cut wood and causes the
saw tomove in the opposite direction of the
chain rotation. The saw is driven straight
back toward the operator.
S Pull-In can occur when the moving chain
contacts a foreign ob ject in the wood in the
cut along the bottom of the guide bar and the
saw chain is suddenly stopped. This sudden
stopping pulls the saw forward and away
from the operator and could easily cause the
operator to lose control of the saw .
Avoid Pinch--Kickback:
S Be extremely aware of situations or obstruc-
tions that can cause material to pinch the top
of or otherwise stop the chain.
S Do not cut more than one log at a time.
S Do not twist the saw as the bar is with-
drawn from an undercut when bucking.
Avoid Pull--In:
S Always begin cutting with the engine at full
speed and the saw housing against wood.
S Use wedges made of plastic or wood.
Never use metal to hold the cut open.
Kickback Path
Clear The
Working Area
Avoid Obstructions
REDUCE THE CHANCE OF
KICKBACK
S Recognize that kickback can happen.
With a basic understanding of kickback,
you can reduce the element of surprise
which contributes to accidents.
S Never let themoving chain contact any ob-
ject at the tip of the guide bar.
S Keep the working area free from obstruc-
tions such as other trees, branches, rocks,
fences, stumps, etc. Eliminate or avoid any
obstruction that your saw chain could hit
while you are cutting through a particular log
or branch.
S Keep your saw chain sharp and properly
tensioned. A loose or dull chain can increase
the chance of kickback occurring. Follow
manufacturer’s chain sharpening and main-
tenance instructions. Check tension at regu-
lar intervals with the engine stopped, never
with the engine running. Make sure the bar
clamp nuts are securely tightened after ten-
sioning the chain.
S Begin and continue cutting at full speed. If
the chain is moving at a slower speed, there
is greater chance of kickback occurring.
S Cut one log at a time.
S Use extreme caution when re-entering a
previous cut.
S Do not attempt cuts starting with the tip of
the bar (plunge cuts).
S Watch for shifting logs or other forces that
could close a cut and pinch or fall into chain.
S Use the Reduced--Kickback Guide Bar and
Low--Kickback Chain specified for your saw .
MAINTAIN CONTROL
Never reverse
hand p ositions
Stand to the left of
the saw
Thumb on underside of
handlebar
Elbow locked
S Keep a good, firm grip on the saw with both
hands when the engine is running and don’t
let go. A firm grip will help you reduce kick-
back and maintain control of the saw . Keep
the fingers of your left hand encircling and
your left thumb under the front handlebar .
Keep your right hand completely around the
rear handle whether your are right handed or
left handed. Keep your left arm straight with
the elbow locked.
S Position your left hand on the front handle-
bar so it is in a straight line with your right
hand on the rear handle when making
bucking cuts. Never reverse right and left
hand positions for any type of cutting.
S Stand with your weight evenly balanced on
both feet.
S Stand slightly to the left side of the saw to
keep your body from being in a direct line
with the cutting chain.
S Do not overreach. You could be drawn or
thrown off balance and lose control of the
saw.

S Mantenga redondeada la esquina
delantera del marcador de

AVISO: El extremo superior del
marcador de profundidad debe ser
parejo con la mitad delantera,
redondeada con una lima plana.

AJUSTE AL CARBURADOR
ADVERTENCIA: La cadena estará
en movimiento durante la mayor parte de
este prodecimiento. Use el equipo protector
y observe todad las precauciones de seguri-
dad. La cadena no debe moverse con el mo-
tor en marcha lenta.
El carburador ha sido ajustado cuidadosa-
mente en la fábrica. Posiblemente se hagan
necesarios ajustes si se nota cualquiera de las
siguientes condiciones:
S La cadena se mueve con el motor en mar-
cha lenta. V ea procedimiento de MARCHA
LENT A “T”.
S La sierra no anda a marcha lenta. V ea pro-
cedimi ento de MARCHA LENTA “T”.
Marcha Lenta “T”
Deje queel motor trabaje en marcha lenta. Si
la cadena se mueve, la marcha lenta es de-
masiado. Si el motor se para, la marcha len-
ta es demasiado lenta. Ajuste las revolu-
ciones hasta que el motor se mantenga en
marcha sin que la cadena se mueva (la mar-
cha lenta es demasiado) o que el motor se
ahogue (la marcha lenta es demasiado len-
ta). El tornillode la marcha lenta estásituado
arriba del bombeador y marcado con la “T”.
S Gire el tornillo de la marcha lenta “T” a la der-
echa (en el sentido del reloj) para aumentar
las revoluciones del motor .
S Gire el tornillo de la marcha lenta “T” a la iz-
quierda (en contra del sentido del reloj) para
bajar las revoluciones.
