GUARD AGAINST KICKBACK
Kickback is a dangerous reaction that can lead to
serious injury. Do not rely only on the safety devices
provided wtth your saw. As achin 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
an object atthe upper portionof the tip of the guide bar
or when the woodcloses inand pinches the saw chain
in the cut. Contactattheupperportionofthetipofthe
guidebarcan cause the chainto dig intothe object and
stop the chain for an instant. The result is a h'ghtning
fast, reversereaction which kicks theguide bar up and
back toward the operator, ff the saw chain is pinched
along the top of the guide bar, the guide bar can be
dttvenrapidly back towardthe operator. Either ol_these
reactions can cause loss of saw control which can
result in se,'lous injurj.
KICKBACK
PATH
Figure 1
1. Recognize that kickbackcan happen. With abasic
understandingofkickback, youcan reduce theele-
ment of surprise which contributes to accidents.
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
obstructionthat your saw chain couldhit while you
are cutting through aparticular log or 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 regular intervals with the motorstopped,
neverwiththemotor running.Makesurethatbarclamp
nuts are securelytightenedaftertensioningthe chain.
5, Begin and continue cutting only with the chain
moving at full speed. If the chain is moving at a
slower speed, there is greater chance for kickback
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. Watch for 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 your saw.

NOTE
Exposuretovibrations throughprolonged 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.

--A loose chain will wear the bar and itself.
--A loose chain can jump offthe bar while you are
cutting
-- A tight chain can damage the saw andlor break.
eThe chain stretches dudng use, especlallywhen
new. Check tension:
-- each time the saw is'used
-- more frequently when the chain is new
--as' the chain warms up to normal operating
temperature.
_WARNING
Avoid accidental starting. Always unplug the saw
from the power source before adjusting chain
tension.

• The guide bar and cutting chain require con-
tinuous lubrication inorderto remain in operating
condition.
--- Lack of oil will quickly ruin the bar and chain.
-- Too little oil will cause overheating shown by
smoke comingfrom thechain and/or discoloration
of the 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. IMPORTANT POINTS
a. RI! the oil tank every time you use the saw.
See "Specifications" for oil cap location.
b. Wipe off surfacesbe_reflliing with oil toavoid
sawdust ordebrisaccidentallyfallingintothetank

c. Use afunnel to fill the tank and wipe up all
spills. Do notuse the sawuntilitiswiped clean
and is completely dry from spilled oil.
d. Replace the oil cap securely to ensure pro-
per operation of the oiler.
e. Check the otl level indicator frequentJydur-
ing use. Locatetheindicatorinthe saw frame
just below and behindthe front handte. Figure
15. If oil is not visible in the slot when saw is
upright on a level surface, the tank requires
filling.
f. Let saw stand unplugged for 15 minutes
before storing, It isnormal fora small amount
of oil todripoff the barand chain when the saw
is not {n use. The excess oil should be wiped
from the saw before storing.
2. USING THE MANUAL OILER
Yoursaw isequipped withan oileractivatorwhich
manually supplies oil to the bar and chain.
The oiler activator must be used regularly and-
often enough to maintain athin film of oil on the
bar and chatn whlle the saw Is cutting. It is
recommended that the oiler activator be
operated six {6) times aminute and held for
approximately three (3) seconds each time It
is pressed.
a. Operate the oilerbypressingdown onthe oiler
activator with your rightthumb. Figure 15.

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.

A. BASIC CUTTING TECHNIQUE
1. IMPORTANT POINTS
a, Cut wood only. Do not cut metal, plastics,
masonry,non-woodbuildingmaterials,etc.Donot
use yoursawtopryorshoveawaylimbs,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 amount of dirt willquickly dull a chain and
thus, increase the possibilityof kickback.
AKICKBACKWARNING
Kickback can occur when the moving chain contacts
an object atthe upperportionofthetipof theguidebar
orwhen the wood closes inand pinches the sawochain
in the cut. Contact at the upperportion of the tip of the
guide barcan caLU+Sethe chainto d{ginto the object and
stop the chain foPan instant. The result is a lightning
fast, reversereaction which kicks the guide bar up and
back toward the operator, ff the saw chain is pinched
along the top of the guide bar,+the guide bar can be
drivenrapid/ybacktowardthe operator..Either of these
remmtionscan cause loss of saw control which can
result in serious injury.
2. UNDERSTAND REACTIVE FORCES
Pinch-Kickback and Pull-in occur when the chain
is suddenly stopped by being pinched, caught,
or by contacting aforeign object in therWOOd.This
results in areversal of the chain force used to cut
wood and causes the saw to move in the opposite
directionof chain rotation.Either reactioncan result
inlossofcontrolandpossibleseriousinjury+
*Pinch-Kickback:
-- occurswhenthechain, ontopofthe bar,issud-
denly stoppedwhen the topof the bar is used
for cutting.
_drives the sawstraightback towardthe operator.
* Pull-in:
-- occurswhenthe chainonthe bottomof the bar
is suddenly stopped
--pulls thesawforward.

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
•can snap and fall towardthe operator.
d. Check for broken or dead brancheswhichcould
fallonyouwhile cutting,
e. Make sure there is enough room for the tree to
fall. Maintaining a distance of 21/2tree lengths
from the nearest person or other objects.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 aslope.
h. Plan a clear retreat path to the rear and diagonal
to the line of fall. Figure 24. 13
gFELLING SMALL TREES _LESS THAN 6_'
IN DIAMETER
a. If youknowthe directionoffall:
1.) Make asingle felting cut on the sideaway
from the directionof fall
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 which way the tree 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 the notch.
NOTE: if the tree has large buttress roots, re-
move before making the notch Cut intothe but-
tresses ve,_calty, then horizontally Figure25.
a. Make the notchcut. Figure26.
1) Cut the bottom of the n0tch first, through
1/3 ofthe diameter of the tree.
2.) Complete the notch by making the slant
cut.
3.) Remove the notchof wood.
b, Make the feiling cut on the opposite side of the
notch about 2" higher than the bottom of the
notch.
c. Leave enough uncut wood between the felling
cut and the notch to form a hinge. Figure 27.
d,
NOTE: The hinge helps to keep the tree from
twistingand failinginthe wrong direction.
Use awedge if there is any chance that the
tree wil!notfall in the desired direction
HINGE HOLDS THE TREE ON STUMP
ANO CONTROLS THE FALL.
Figure26 F_jure27
AWARNING
Stay on the uphill side of the terrain to avoid the
tree rolling or sliding downhill after it is felled.
e_
g_
NOTE: Before the felling cut is complete,drive
wedges to open up the cut when necessaryto
controlthe directionof fall. Use wood or plastic
wedges but never metal, to avoid kickbackand
chain damage,
Be alert for signsthat the tree isreadyto fall:
1.) cracking sounds
2.) widening ofthe felling<:ut
3.) movement inthe upperbranches.
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
notcut downa partiallyfallentree withyoursaw.

C. BUCKING
Bucking is the term used for cuffing a fallen
tree to the desired log size.
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 log while cut-
ting and never holdthe logwithyourlegortoot.
d. Do not cut in an area where logs, limbs and
roots are tangled such as in a blown down
area. Drag the logsintoacleararea beforecut-
ting by pulling out exposed and cleared logs
first.
e. Make the first bucking cut 1/3 of the way
through the log and finish with a.2/3 cut on
the opposite side. As the log is being cut, it
will tend to bend. The saw can become
pinched or hung in the log if you make the first
cutdeeper than 1/3 ofthe diameter of the log.
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
stress on the log. Figure28,
2. TYPES OF CUTTING USED (Rgure 29)
-- Overcutting - beginon the top sideof the log
with the bottom of the saw against the log;
exert lightpressuredownward.
---Undercutting - beginon the underside of the
log withthe topof thesaw againstthe log;exert
light pressure upward. During undercutting,
the saw will tend topushback at you. Be pre-
pared for this reaction•and holdthe sawfirmly
to maintain control.

,£k WARNING
If saw becomes pinched or hung in a log, don't try to
force it out. Youcould lose control of the saw resulting
in personal injury and/or damage to the saw. Stop the
sawanddrivea wedge ofplasticor wood intothec_until
saw can be removed eastly, Figure 30. Restart the saw
and carefully reenter the cut. To avoid kickback and
chain damage, donot usea metal wedge. Donot attempt

2. PRUNING
a. Limit pruning to limbs shoulder height or
below. Do notcut if branches are higherthan
yourshoulder.Get a professionalto dothejob.
b. Refer to Figure 34 for pruning technique.
1.) Undercut 1/3 of the way throughthe limb
near thetrunk of the tree.
2.) Finish_vithan overcut fartheroutfromthe
trunk.
3.) Keep out of the way of the falling limb.
4.) Cut the stump flush near the trunk of the
tree.
A WARNING
Be alert forand guard against kickback. Do not allow
the moving chain to contact any other branches or
ob_=ctset the nose of the guide bar when debmnch-
ing or pruning. Allowing such contact can result in
serious Injury.

1. DEBRANCHING
a. Always debranch a tree after It is cut down.
Onlythen can debranchingbedone safelyand
properly.
b. Leave the langerlower limbs to support the
tree as you work.
c. Start at the base of the felled tree and work
towards the top, cutting branches and limbs.
Remove small limbs with one cut. Figure 33.
d. Keep the tree between you and the chain.
Cut from the side of the tree opposite the
branch you are cutting.
e. Remove larger, supporting branches with
the 1/3, 2/3 cutting techniques deecdhed in
the bucking section.

b, Clean oil holes at least once for each
five hours of operation.
c. Remove sawdust from the guide bar
groove periodically with a putty knife or
a wire. Figure44.

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.
