GUARD AGAINST KICKBACK
Kickback is a dangerous reaction that can lead to
serious injury. Do not rely only on the safety devices
provided wtthyoursaw. Asa chin saw user, you must
take special safety precautions to help keep your
cutting jobs free from accident or injury.
_k KICKBACK WARNING
Kickback can occur when the moving chain contacts
anobject atthe upper portionofthetip ofthe guide bar
or when the woodclosesinand pinches the saw chain
in the cut. Contactattheupperportionofthetipofthe
guidebarcan cause thechainto digintothe objectand
stop the chain for an instant. The result is a h'ghtning
fast, reversereaction which kickstheguide bar upand
back toward the operator, ff the saw chain ispinched
along the top of the guide bar, the guide bar can be
dttvenrapidlyback towardtheoperator. Either ol_these
reactions can cause loss of saw control which can
resultin se,'lous injurj.
KICKBACK
PATH
Figure 1
1. Recognize that kickbackcan happen. With abasic
understandingofkickback,youcanreduce theele-
mentof surprisewhichcontributestoaccidents.
2. Never let the moving chain contact any object at
the tip of the guide bar.Figure 1.
3. Keep the working area free from obstructions
such as other trees, branches, rocks, fences,
stumps, etc. Figure 2. Eliminate or avoid any
obstructionthatyoursaw chain couldhit whileyou
are cutting through a particular logor branch.
4. Keep your saw chain sharp and properly
tensioned. A loose or dull chain can increase the
chance of kickback. Follow manufacturer's chain
sharpening and maintenance instructions.Check
tensionat regularintervals with the motorstopped,
neverwiththemotor running.Makesurethatbarclamp
nuts are securelytightenedaftertensioningthechain.
5, Begin and continue cutting only with the chain
moving at full speed. Ifthe chain is moving at a
slowerspeed, there isgreater chance forkickback
to o_ur.
6. Cut one log at a time.
7. Use extreme caution when reentering a previous
cut.
8."Do not attempt plunge cuts.
9. Watchfor shiffing logs Orother forces that could
close a cut and pinch or fall into the chain.
10. Use the Reduced-Kickback Guide Bar and Low-
Kickback Chain specified for yoursaw.

NOTE
Exposuretovibrationsthroughprolonged use of this tool may produce Whitefingerdisease (Raynaud's phenomenon)
This phenomenon reduces the hand's ability to feel and regulate temperature, produces numbness and burning
sensations and can cause nerve and circulation damage and tissue necrosis.
An anti-vibration system designed to reduce engine vibration is recommended for those using power tools on a
regular or sustained basis. An anti-vibration system does not guarantee the avoidance of Whitefinger disease,
Continual and regular users must monitor closely theii-use of power tools and physical condition.

-- Too little oil will cause overheating shown by
smokecomingfrom thechainand/ordiscoloration
ofthe guide bar rails.
• Use Sears Bar and Chain Lubricant #71-36554 to
fill the oil tank. Clean SAE 30W oil may also be
-used. Never use waste oi/for thispurpose.

1. Check the contact between the stone and
chain before advancing the Power Sharp _
Knob. If stone is contacting the chain, the
chain can be sharpened without advancing
the knob.
2. Do not advance the Power Sharp® Knob
more than one or two clicks at any one
sharpening. Otherwise, excessive wear to
the chain and sharpening stone can occur.
3. Note the flow of sparks visible during
automatic sharpening:
_A light flow of sparks indicates proper
sharpening.
--A heavy flow Of sparks or no sparks in-
dicates improper sharpening.
4. Keep all cutters the same length. The side
plates shou}d always bekept approximately
1132 of an inch longer than the top plate.
Figure 21.
5. Preserve the original cutter angles carefully
and uniformly.
6. Avoid hand filing into the bottom of the top
plates. Keep guide lines on file guide aligned
with the chain and guide bar.

A. BASIC CUTTING TECHNIQUE
1. IMPORTANT POINTS
a, Cut wood only. Do not cut metal, plastics,
masonry,non-woodbuildingmaterials,etc.Donot
useyoursawtopryorshoveawaylimbs,rootsor
otherobjects+
b. Stop the saw if the chain strikes a foreign
object. Inspecttheunitandrepairorreplaceparts
as necesary+
c. Keep the chain out of dirt and sand. Even a
small amountofdirtwillquickly dull a chain and
thus, increasethe possibilityof kickback.
A KICKBACKWARNING
Kickback can occur when the moving chain contacts
an object atthe upperportionofthetipof theguidebar
orwhen the woodcloses inand pinches thesawochain
in the cut. Contact at the upperportion ofthetip ofthe
guide barcan caLU+Sethe chaintod{gintothe object and
stop the chain foPan instant. The result is a lightning
fast, reversereaction whichkicksthe guide bar up and
back toward theoperator, ff the saw chain is pinched
along the top of the guide bar,+the guide bar can be
drivenrapid/ybacktowardthe operator..Eitherofthese
remmtionscan cause loss of saw control which can
result inserious injury.
2. UNDERSTAND REACTIVE FORCES
Pinch-Kickback and Pull-in occur when the chain
is suddenly stopped by being pinched, caught,
or bycontacting aforeignobject in therWOOd.This
results in a reversalof the chain force used tocut
wood and causes the sawto move in the opposite
directionofchainrotation.Eitherreactioncan result
inlossofcontrolandpossibleseriousinjury+
* Pinch-Kickback:

B. TREE FELLING TECHNIQUES
1. PLAN YOUR SAWING OPERATION CAREFULLY
IN ADVANCE
a. Clear the work area. You need a clear area all
around the tree where you+can have secure
footing+
+b+Study the natural conditions that can cause
the tree to fall in a particular direction,
1.)The WIND directionand speed+
2.)The LEAN ofthetree.
&)WEIGHTED withBRANCHES on one side.
4.) SurroundingTREES and OBSTACLES.
c. Look for decay and rot. If the trunk is rotted, it
• cansnap and falltowardtheoperator.
d. Check for broken or dead brancheswhichcould
fallonyouwhilecutting,
e. Make sure there is enough room for thetree to
fall. Maintaining a distance of 21/2tree lengths
from the nearest person or otherobjects.Motor
noisecan drownoutwarningcall.
f. Remove dirt, stones, loose bark, nails, staples,
and wire from the tree where cuts are to be
made.
g. Plan to stand on the up-hill side when cuffing
on a slope.
h. Plan a clear retreat path to the rearand diagonal
tothe line of fall. Figure24. 13
g FELLING SMALL TREES _ LESS THAN 6_'
IN DIAMETER
a. Ifyouknowthe directionoffall:
1.) Make a single felting cuton the sideaway
from the directionoffall
2.) Cut all the way through.
3.) Stop the saw, put it down, and get away
quickly on your planned retreat path.
b. If you are not sure whichway thetree willfall,
use the notch method described for felling
large trees.
AWARNING
Do not cut a tree in any manner that would en-
danger people, cause property damage, or strike
a utility line. Notify the utility company im-
mediately if a tree makes any contact with a utility
line.
,_, 4s
Figure24 Figure25
3. FELLING LARGE TREES-- 6" DIAMETER
OR MORE
The notch method is used to cut large trees, A
notch is cut on the side of the tree in the desired
direction of fall. After a felling cut is made on the
opposite side of the tree, the tree will tend to fall
into thenotch.
NOTE: if the tree has large buttress roots, re-
move before making the notch Cut intothe but-
tressesve,_calty, then horizontally Figure25.
a. Makethenotchcut. Figure26.
1) Cut the bottom of the n0tch first,through
1/3ofthe diameterof thetree.
2.) Complete the notch by making the slant
cut.
3.) Remove the notchof wood.
b, Make the feiling cuton theopposite side ofthe
notch about 2" higher than the bottom of the
notch.
c. Leave enough uncut wood between thefelling
cutand the notch to form a hinge. Figure 27.
d,
NOTE: The hinge helps to keep the treefrom
twistingand failinginthewrong direction.
Use a wedge if there is any chance that the
tree wil!notfall inthe desired direction
HINGE HOLDS THE TREE ON STUMP
ANO CONTROLS THE FALL.
Figure26 F_jure27
A WARNING
Stay on the uphill side of the terrain to avoid the
tree rolling or sliding downhill after itisfelled.
e_
g_
NOTE: Beforethe fellingcut is complete,drive
wedges to open up the cut when necessaryto
controlthe directionoffall. Use woodor plastic
wedges but never metal, toavoidkickbackand
chaindamage,
Bealert for signsthatthetree isreadytofall:
1.) cracking sounds
2.) widening ofthefelling<:ut
3.) movement intheupperbranches.
As the tree starts to fall, stop the saw; put it
down, and get away quickly onyour planned
retreat path.
Be extreme!y cautious with partially fallen
trees that may be poody supported.When a
tree doesn'tfall completely, set the saw aside
and pull down the tree with a cable winch,
block and tackle or tractor.To _oid injury,do

C. BUCKING
Bucking is the term used for cuffing a fallen
tree to the desired logsize.
1. IMPORTANT POIN_
a. Cutonlyone log ata time,
b. Cut shattered wood very carefully. Sharp
pieces of wood could be flung toward the
operator.
c. Use a sawhorse to cut small logs. Never
allow another personto holdthe logwhilecut-
tingand never holdthelogwithyourlegortoot.
d. Do not cut in an area where logs, limbs and
roots are tangled such as in a blown down
area. Dragthe logsintoa cleararea beforecut-
ting by pulling out exposed and cleared logs
first.
e. Make the first bucking cut 1/3 of the way
through the logand finish with a.2/3 cut on
the opposite side. As the logis being cut, it
will tend to bend. The saw can become
pinched or hung in the log if you make the first
cutdeeper than 1/3ofthe diameter of thelog.
f. "Give special attention to logs under strain
to prevent the saw from pinching, Make the
first cut on the pressure side to relieve the
stresson thelog. Figure28,
2. TYPES OF CUTTING USED (Rgure 29)
-- Overcutting - beginon the top sideof thelog
with the bottom of the saw against the log;
exert lightpressuredownward.
---Undercutting - beginon the underside ofthe
log withthe topofthesaw againstthelog;exert
light pressure upward. During undercutting,
the saw will tend topushback at you. Be pre-
pared for this reaction•and holdthe sawfirmly
tomaintain control.

SPROCKET
• Clean the sprocket and surrounding area
daily during heavy use of the saw.
• Inspect the sprocket regularly for wear. A
worn sprocket will cause the chain to run er.
raticatly and will shorten the life of the bar
and chain. Figure46.
• Replace the sprocket whenever a new chain
is installed. The sprocket matches the pitch
of the chain. If both the chain and sprocket
are replaced at the same time, they wilt wear
together. A worn sprocket will be out of pitch
with the new chain and thereby can cause un-
necessary wear.
