or when thewood €loses in and ptncheethesew chain
in the cut, Contact at the upper portton of the tip of the
guide barcan cause the chain to dig into theobject and
stop the chain for an Instant. The result is s lightning
fast, reverse reaction which k_cksthe guide bar upand
back toward the operator, ff the saw chain ispinched
along the top of the gulde bar, the guide bar can be
driven rapidly back toward the operator. Either of
these reactions can cause loss of saw control which

KICKBACK
Begin and continue cutting at lull throttle, if the
chain is moving at a slower speed, there is greater
chance for kickback.
Cut only one log at a time.
Use extreme caution when re-entering a cut.
Do not attempt plunge cuts.
Watch for shifting logs orotherforces that could
close a cut and pinch or fail into the chain.
Use only the Reduced-Kickback Guide Bar and
Low.Kickback Chain specifiedfor yoursaw.
MAINTAINING
AVOID
OBSTRUCTIONS
!
..............,=, ,,
1. Recognize that kickback can happen. With a
basic understanding of kickback, you can reduce
the element of Surprise which contributes to
accidents.
2. Never iat the moving chain €ontact anyobject at the
Up of the guide bar. Figure1.
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 could hit while you
are cutting through a particular log or branch.
4. Keep your saw chain sharp and properly tensioned. FollowSears chainsharpeningand maintenance instructions.Checktensionat regular intervals
withtheenginestopped,neverwiththeenginerunning.
Make sure the bar clamp nuts are securelytightened
after tensioningthe chain. A looseor dull chain can
increasethe chance of kickback.

CONTROL
Keep a good firm gdp on the saw with both hands
when the engine is running and don't let go.
Figu_r_e
3, A firm grip can neutralize kickback and
help you 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
you are right handed or left handed. Keep your left
arm straight with the elbow locked.
Position your left handon the front handlebar SOit
isin a streight line with your dght hand onthe rear
handle when making bucking cuts. Figure3. Never
reverse right and left hand positionsfor any type of
cutting.
Stand with your weight evenly balanced on
both feet.
Stand slightly to the left side of the saw to keep
your body and head from being in a direct line
with the cutting chain. Figure 3.
Do not overreach. You could be drawn or thrown
Loftbalance and lose control of the saw.
Never cut above shoulder height. It is difficultto
maintaincontrolofthe saw aboveshoulderheight and
places the chain dangerously close to your upper
body.

TENSION
• Correct chain tension is very important:
--a loose chain wilt wear the bar and itself.
--a loose chain can jump off the bar while
you are cutting.
--a tight chain can damage the saw and/or
break.
• The chain stretches during use, especially
when new. Check tension:
each time the saw is used
-- more t_requentiywhen the chain isnew
as the chain warms up to normal operating temperature
• Chain tensioning procedure:
NOTE: The bar clamp nuts must be no more than
finger tight to tension the chain correctly.
NOTE: Hold up the tip of the Guide Bar through
step 4.
1. Hold thetipof theguide bar up and turnthe adjusting

1. FUEL SAFETY
a. Use only recommended fuel mixtures.
b. MIx and pour fuel outdoors and where there are
no sparks or flames.
c. Use a container approved for fuel.
d. Do not smoke or allow smoking near fuelor the
tool or while using the tool.
e. Wipe up all fuel spills before starting engine.
h Move at least 10 feet away from fueling site
before starting engine.
g, Stop engine before removing fuel cap. Allow
the engine to cool before refueling.
h. Before storing the tool, use up fuel left in the
carburetorand fue!linesbystartingthe engineand
letting it run until it stops.
i.
Store tool and fuel in an area where fuel vapors
cannot reach sparks or open flames from water
heaters, electric motors or switches, furnaces,
etc.
2. FUEL
MIXTURE
* Your tool Is powered by • two-cycle engtne
which requires a fuel mixture of regular
• unleaded ga=ollne and a high quality engine oll
specially made for 2-cycle, air cooled engines.
The internal design of the 2-cycleengine requires
lubricationof moving parts.Lubricationisprovided
when therecommendedmixture ofgasolineand oil
is used.
• Gasoline must be clean and not over two months
old. Gasolinewill chemicallybreak down and form
compounds thatcause hardsta_ingand damage in
2-cycle engines.
important. Toomuch oil in the mixturewill foulthe
spark plug.
[CAUTION:! Toolittle oil or incorrect oil will cause
the engine to overheat and seize.
• Always mix the fuel thoroughly in a container
since gasolineand oildo notreadilycombine.Donor
mix gasolineand oi! directlyin the fuel tank.
3. USE THE FOLLOWING
ONLY:
SEARS CRAFTSMAN 2-CYCLE ENGINE OIL
MIXED AT 40:1 IS*STRONGLY RECOMMENDED.
CONSULT THE INSTRUCTIONS ON THE OIL
CONTAINER FOR PROPER MIXING.
1 Part Oil to 40 Parts Gasoline :
3.2 FI Oz Oil to 1 Gallon Gasoline
8.0 FI Oz Oil to 2.5 Gallon Gasoline
Not all air-cooledengine oilshavethe same qualities.If Sears Craftsman2-cycleengine oil is not
available, use a good quality,2-cycle engine oil
recommendedfor air-cooledengines Mix at a ratio
of 16:1(8 07. oilto 1 gallon gasoline).A 16:1 fuel
mixturewith these oilswillassure adequate lubricationfor your engine.
4. DO NOT USE:
• NMMA Oil -- National Marine Manufacturers
Association {formerly BIA)
Does not have proper additives for 2-cycle, aircooled engines and can c_use engine damage.
• AUTOMOTIVE OIL -Does not have proper additives for 2-cycle, aircooled engines and can cause engine damage.
CAUTION
Experience indicates that alcohol blended fuels (called
gasohol or using ethanol or methanol) can attract
moisture which leads to separation and formation of
acids dudng storage. Acidic gas can damage the fuel
system of an engine while in storage.To avoid engine
problems, do not leave fuel in the unit when storing
for 30 days or longer. Start the engine and let it run
until the fuel lines and carburetor are empty. Use fresh
fuel next season. See the "Storage" section for additional information. Never use engine or carburetor
cleaner pmdu,#_s in the fuel tank or permanent
damage can occur.
NOTE: if you do not want to remove the gasoline
from your unit, SEARS CRAFTSMAN Fuel
Stabilizer(#71-33500) may be added to gasoline
te_ in the tank to minimize gum deposi_ and
adds. If the tank is almost empty, mix stabilizer
with fresh gasoline in a separate containerand
add to the tank.
5. HOWTO MiX FUELAND FILL TANK
a. pour the proper measure of engine oil intoan approved,
marked container. The, fill the container with regular
unleaded gasoline,
NOTE: If fuel is already in the container, add the proper
measureof engine oil. Then, close the containertightlyand

CUTTING
II I
A KICKBACK WARNING
Kickbackcan occur when the moving chain contacts an
object st the upper portion of the tip of the guide bar or
when the wood closes in and pinches the saw chain in
the cut. Contact at the upper portion of the tip of the
guide barcan causa the chsin to dig into the object and
stop the chain for an instant. The result is s lightning
fast, reveme reaction which kicks the guide bar up and
back toward the operator. If the saw chain is pinched
along the top of the guide bar, the guide bar can be
drivenrapidlybacktowardtheoperator.
Eitherof these
reactions can cause loss of saw control which can
result in serious/injury.
2. UNDERSTAND
REACTIVE FORCES
Pinch-Kickback and Pult-ln occur when the chain
is suddenly stopped by being pinched, caught, or
by contacting a foreign object in the wood. This
resultsina reversalofthe chainforceused to cutwood

TECHNIQUES
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 of the tree.
3.) WEIGHTED with BRANCHES on one side.
4.) SurroundingTREES and OBSTACLES.
c. Look for decay and rot. If the trunk is rotted,
itcould snap and fall toward the operator.
d. Check for broken or dead branches which
could fal! on you while cutting.
e. Makesure there is enough room for thetreeto
fall. Maintaina distance21/2tree lengths from the
nearest personor other object.Engine noisecan
drown out a warningcall.
f. Remove dirt, stones, loose bark, nails,
staples, and wire from the tree where cuts
are to be made.
g. Plan rostand on the up-hill side when cutting on a slope. Figure 16.
h. Plan s clear retreat path to the rear and
diagona! to the line of fall. Figure 17.
2. FELUNG SMALL TREES _ LESS THAN 6"

a Ifyou knowthedirectionoffall:
1.) Make a single,horizontalfelling cut on the
side away from the directionof the fall.
2.) Cut allLheway through.
3.) Stop the saw, put it down, and get away
quicklyon yourplannedretreat path.
b. If you are not sure which way the tree willfall,
use the notchmethod describedfor fellinglarge

PRUNING
2. PRUNING
• Work slowly, keeping both hands firmly gripped .
on the saw. Maintain securefootingand balance.
• Watch out for spfingpoles. Use extreme caution
when cutting small size limbs.Slender material can
catchthesaw chain-andbewhippedtowardyouor pull
you off balance.
• -Be alert for springback. Watch Outfor branches
that are bent or under pressure as yOUare cutting
to.avoidbeing struck bythe branch orthe saw when
the tension in the woodfibersisreleased.
• Keep a clear workarea. Frequently,clear branches
•out ofthe way to avoidtrippingover them.
_kWARNING
Never climb into a tree to debmnch or prune. Do not
stand on ladders, platforms, a log, or in any position
which can cause you to lose your balance orcontroi of
thesaw.
,
MAINTAIN SECURE FOOTING
a. Limit pruning to limbs Shoulder height or
below. Do not cut if branches are higherthan
your shoulder. Get a professional to do the
job.
b. Refer to Figure 27 for the pruning technique.
1.) Undercut 1/3 of the way throughthe limb
near the trunkof the tree.
2.) Finish with an overcutfarther out from the
trunk.
3.) Keep out of the wayof thefalling timb.
4.) Cut the stump flush near the trunkof the
tree.
=_IbWARNING
Be alert for and guard against kickback. Do not allow
the moving chain to contact any other branches or
objects at the nose of the guide bar when debranching
orpruning. Allowingsuch,contact can resultin seriotJs
injury.
DEBRANCH!NG
/
a. Always debranch a tree after it is cut down.
Only then can debranching be done safely
and properly.
b. Leave the larger lower limbs to support the
tree as you work.
c. Start at the base of the felled tree and work
toward the top, cutting branches and
limbs. Remove smal! limbswith one cut. Figure26.
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 described in

A WARNING
Maintain the proper hook angle according to the
manufacturer's specification for the chain you are
using. Improper hook angle will increase the chance of
kickback which can result in serious injury. Figures31
&33.
5.)Correct Depth Gauges.
2. GUIDE BAR MAINTENANCE
• Conditions which can require guide bar
maintenance:
--saw cuts to one side
--saw has to be forced through a cut
--inadequate
supply of oil to bar and
chain;
• Check the condition of the guide bar each
time the chain is sharpened. A worn guide
bar will damage the chain and make cutting
more difficult,Reversebar after every cleaning.
• Replace the guide bar when:
--the inside groove of the guide bar rails is
a.) Place depth gauge tool over each cutter

ACCELERATION ADJUSTMENT
tfengine diesor hesitatesinsteadofaccelerating,turn
the Low Speed Mixture Screw 1/16of a turn at a
time counterclockwise until you have smooth
acceleration.
HIGH SPEED MIXTURE ADJUSTMENT
CAUTI_..]
Adjustments as small as 1/16 of a
turn can affect engine performance. It is important to turn thescrew only 1/16of a turn per ad|ustment and test the performance of the saw before
making further adjustments.
a. Make a testcut.
b. Adiust theHigh Speed MixtureScrew 1/16ofa turn
as follows:
---- C!ockwJseff saw smokesor losespower.
-- Counterclockwiseif the saw has speed out of
the cutbut lacks powerin the cut.
c. Repeat testcut.
d. Continue 1116of a turn adjustmentsuntilthe saw
runs smoothlyincut.
Atoo lean highspeed setting (clock°
wise adjustment) will cause engine damage to
any 2,cycle engine from overheating and lack of
lubrication. Never set the high speed mixture
screw so farclockwise th*atyou have high engine
speed but lack power while cutting. An effective
approach follows:
-- Turn screw counterclockwise until engine
loses power while cutting,
-- Then, turn screw clockwise in 1/16 of a turn
increments only until the engine has power
while cutting.
NOTE: if the unit will not operate properly after
makingthese adjustments, takethe unitto yourSears

AIR FILTER
• A dirty airfilter:
-- reduces cutting power.
-- increases fuel consumption
• Clean the air filter:
-- hequenlly, especiallyin very dusty+
conditions.
-- always alter 10 tanks of fuel mixture or 5 hours
of operation, whichever is less.
• Replace the air filter if it is damaged.
Never operate theunit without the
air filter in place to avoid damage to the engine.
+• +Take the saw to your Seam Service Center for
full clutch inspection and service alter each 100
hours of operation. It is recommendedthatyou do
nottty toser_ce theclutch ordrum/sprocket
yourself
unlessyou are a competentsmall engine mechanic
and have theproper clutchservicetools.Properdisassemblyand repairofthe clutchisextremelyimportant to the life of the engine and the safety of the
operator.
• Clutch maintenance is required when :
-- the chain continues to turn while engine idles
after the idle speed screw has been adjusted
to its capacity.
-- slippage occurs during a cut.
-- a chattering noise occurs during cutting.
• Clean the clutch, drum, sprocket, and surrounding +
area daily during heavy use ofthe s_w, Checktosee
thatthe clutchdrum turnsfreelyand smoothly.
• Inspect the sprocket regularly for wear. A worn

O. STORAGE
2O
When your saw is to be stored for over 30 days;
always:
1. Runthe fuel out ofthe fueltank,carburetor,and fuel
linesby startingthe engine and allowingitto run at
idlespeed untilitstops. (See "Fueling YourEngine:')
NOTE: Itisimportanttopreventgum depositsfrom
formingin essentialfuel systemsparts suchas the
carburetor, fuel filter, fuel hose, or tank during
storage. Alcohol blended fuels(called gasoholor
using ethanol or methanol) can attract moisture
which leads to separation and formationof acids
during storage. Acidic gas can damage the fue!
system of an engine while in storage.
NOTE: If you do not want to remove the gasoline
from your unit, SEARS CRAFTSMAN Fuel
Stabilizer (#71-33500) may be added to gasoline
left in the tank to minimize gum deposits and
acids. If the tank is almost empty, mix stabilizer
with fresh gasoline in a separate container and
add to the tank.
ICAUTiON:I Wear protective gloves when handling the chain. The chain is sharp and can
cut you even when it is not moving.
2. Drain oil tank.
3 Remove, clean, and dry the bar and chain.
4.
To protect the chain from rust, store it in a container
filled with oil.
5. Apply a coating of oil to the entire surface of
the bar and wrap it in heavy paper, cloth, or
plastic.
6. Clean the outside surfaces of the engine.
7. Store the saw in adry place, out of the reach of chil+
dren, and away from where fuel vapors can reach
open flames from hot water heaters, furnaces, etc.
