SPECIAL SAFETY SECTION
GUARD AGAINST KICKBACK
Kickback isa dangerous reaction that can lead to serious
personal injury. Do not rely only on the safety devices
provided with your saw. As a chain saw user, you must
take special safety precautions to help keep your cuffing
jobs free from accident or injury.
. _\KICKBACK WARNING
Kickback can occurwhen the moving chain contacts
anobject atthe upper portion ofthe tip of the guide bar
orwhen the wood closesin and pinches thesaw chain
inthecut, Contact at theupper portion of the tip of the
guide barcan cause the chain to dig intothe object and
stop the chain for an instant. The result is a lightning
fast, reverse 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
driven rapidly back toward the operator. Either of
these reactions can cause loss of saw control which
can result inserious personal injury.
, // i: . OKBACKPAT.
REDUCETHECHANCEOF
KICKBACK
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 letthemoving chain contact anyobject atthe
tip of the guide bar. Figure1.
3. Keep the working area free from obstructions
such as other trees, branches, recks, fences,
stumps, etc. Figure 2. Eliminate or avoid any
obstruction that your saw chain could hit while you
are cutting through a particular log or branch.
4. Keep your saw chain sharp and properly ten-
sioned. Followmanufacturer'schainsharpeningand
maintenance instructions.Check tension at regular
intervalswiththeenginestopped,neverwiththeengine
running. Make sure the bar clamp nutsare securely
tightened aftertensioningthe chain. A looseor dull
chaincan increasethechance of kickbacktooccur.
5. Begin and continue cutting at full throttle. If the
chain is moving at a slower speed, there is greater
chance for kickback to occur.
6. Cut one log at a time.
7. Use extreme caution when re-entering a previous
cut.
8. Do not attempt plunge cuts.
9. Watch for shifting logs or other forees that could
close a cut and pinch or fall into the chain.
10. Use the Reduced-Kickback Guide Bar and Low-
Kickback Chain specifiedfor your saw.

MAINTAIN CONTROL
1. Keep a good firm grip on the saw with both hands
when the engine is running and don't let go.i
Figure 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 Orleft handed. Keep your left
arm straight with the elbow locked.
2. Position your left hand on the front handlebar so it
isin a straight line with your right hand on the rear
handle when making bucking cuts. Figure3. Never
reverserightand lefthand positions.
3. Stand with your weight evenly balanced on
both feet.
4. Stand slightly to the left side of the saw, to keep
your body from being in a direct line with the
• cutting chain. Figure 3.
5. Do not overreach. You could be drawn or thrown
off balance and lose control of the saw.
6. Do not cut above shoulder height. It is difficult to
maintain control of the saw above shoulder height.

KNOW YOUR SAW
1. Read your Operator's Manual carefully untilyoucom-
pletely understand and can follow all safety rules and
operating instructions before attempting tooperatethe
unit.
2. Restrfot the use of your saw toadultusarswhounder-
stand and follow the safety rules, precautions, and
operating instructionsfoundin this manual.
PLAN AHEAD
1. Wear personal protective gear. Figure 4. Always use
steel-toedsafetyfootwear Withnon-slipsoles;snug-fitting
clothing;heavy-dutynon-s!ipgloves;eye protectionsuch
as non-fogging,vented g0ggles or face screen;an ap-
provedsafety hard hat, andsoundbarders -- earplugsor
mufflers to protectyour hearing. Regular users should
have hearingchecked regularly as chain saw noisecan
damage hearing.
2. Keep children, bystanders, and pets Out of the work
area -- a minimum of 30 feet (10 meters). Donotallow
other people or animals to be near the chainsaw when
starting oroperating the chain saw.
3. Do not handle or operate a chain saw when you are
fatigued, ill, or upset; or if you have taken alcohol,
drugs or medication. You must be in good physical
condition and mentally alert. Chain saw work is
strenuous. If you have any condition that might be
aggraveted bystrenuous work, check withyour doctor
before operating a chain saw.
4. Do not attempt to use your chain saw during ba
weather conditions such as strong wind, rain, sno_
etc., or at night.
5. Plan your sawing operation carefully in advance, r

AVOID REACTIVE FORCES
Pinch-Kickback and Pull-in occur when the chain i
suddenly stopped by being pinched, caught, or b
contacting a foreign object in the wood. This resultsin,
reversalofthechainforce usedtocutvKx:x:landcausesthesat
to move in the oppositedirectionof chain rotation. Pinch
Kickback drives the saw straight back towardthe operato
Pull-in pulls the saw awayfrom the operator.Either reaction:
canresult inloss ofcontrolandpossibleseriouspersonalinjuq
To avoid Pinch-Kickback:
1.
Be extremely aware of situations or obstruction=
that can cause material to pinch the top of or other
wise stop the chain.
2.
Do not cut more than one log at a time.
3.
Do not twist the saw as the bar iswithdrawn from ar
under-cut when bucking,
TO
avoid Pull-in:
1.
Always begin cutting with the engine at full throttk
and the spur against the wood.
2;
Use wedges made of plastic or wood, (never of metar
to holdthe cutopen.
HANDLE FUEL WITH CAUTION
t. Eliminate all soumes of sparks or flame in the area._
where fuel is mixed, poured, or stored. There shoulc
be no smoking, open flames, orwork that couldcaus_
sparks.
2. Mix and pour fuelin an outdoor area, on bare ground
store fuel ina cool, dry,well-ventilated place; andusE
an approved, marked container for all fuel purposes
3. Wipe up all spilled fuel before starting your saw
4. Move at least .10feet (3 meters) away from fuel an(
fueling site before starting the engine.
5. Do not smoke while handling fuel or while operatin.(
the saw.
6. Turn the engine off and let your saw cool befon
removing the fuel tank cap and refueling the unit
7. Let the saw cool in a non-combustible area, notor
dry leaves, straw, paper, etc.
OPERATE YOUR SAW SAFELY
1. Do not operate a chain saw that is damaged, im-
properly adjusted, or not completely and securely
assembled.
2. Operate the chain saw only in outdoor areas.
3. Do not operate the saw from a ladder or in a tree.
4. Position all parts of your body to the leff of cut and
away from the saw chain when the engine is
running.
5. Cut wood only. Do not use your saw to pry or shove 3.
away limbs, roots or other objects.
6. Make sure the chain willnot make contact with any ob- 4.
ject while starting the engine. Nevertrytostartthe saw
when the guide bar is in acutor kerf.
7. Use extreme caution when cutting small size brush
and saplings. Slender material can catch the saw
chain and be whipped toward you or pull you off
balance.
8. Be alert for springback when cutting a limb that is
under tension so you will not be struck by the limb or
saw when the tension in the wood fibers is released.
9. Do not put pressure on the saw at the end of a cut.
This can cause you to lose control when the cut is
completed.
10. Stop the engine before setting the saw down.
MAINTAIN YOUR SAW IN GOOD
WORKING ORDER
1. Have all chain saw service performed by a qualified
service dealer with the exception of the items listed
in the maintenance section of this manual. For
example, if improper tools are used to remove or hold
the flywheel when servicing the clutch, structural
:damage to the flywheel can occur and cause the
flywheel to burst.
2. Keep fuel and oil caps, screws and fasteners
securely tightened.
3. Keep the handles dry, clean, and free of oil or fuel
mixture.
4. Make certain the saw chain stops moving when the
throttle trigger is released. For correction, refer to
page 20 for carburetor idle adjustment instructions.
5. Stop the saw if the chain strikes a foreign object. In-
spect the unit and repair or replace parts as necessary.
6. Disconnect the spark plug before performing any
maintenance except for carburetor adjustments.
7. Never modify your saw in any way. Use only attach-
ments supplied or specifically recommended by the
manufacturer.
8. Always replace the handguard immediately if it
becomes damaged, or broken or is otherwise
removed.
CARRY AND STORE YOUR SAW SAFELY
1. Hand carry the unit with the engine stopped, the
muffler away from your body, and the guide bar and
chaintothe rearcovered preferablywitha scabbard.
2.
Beforetransporting in any vehicle or storing in any
enclosure, allow your saw to cool completely, cover
the bar and chain and properly secure to avoid
turnover, fuel spillage or damage.
Drain oil and fuel tank before storing for more than
30 days.
Store in a dry area out of reach of children and away
from where fuel vapors can reach sparks or an open
flame from hotwaterheaters,furnaces, etc.
NOTE: Exposure to vibrations through prolonged use of
chain saws may produce Whitefinger disease
(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
chainsaws ona regular orsustained basis. An anti-
vibration system does not guarantee the
avoidance ofWhitefinger disease. Continual and
regular users must monitor closely their use of
chain saws and physical condition.
Notice: Refer to the Code of Federal Regulations, Section
1910.266(5); 2.5.1 of American National Standard
Safety Requirements for Pulpwood Logging, ANSI
03.1-1978; and relevant state safety codes when
usinga chainsaw for loggingpurposes.

E. CHAIN TENSION
• Correct chain tension is very important:
--a loose chain will 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.
• Chain tension is correct when the chain:
--can be lifted about 1/8" from the Guide Bar
at a point near the middle of the bar, and
--will move freely around the bar.
..• The chain stretches during use, especially
when new. Checktension:
-- each time the saw isused
-- more freduently when the chain isnew
-- as thechainwarms upto normal operating tem-
perature
• The Bar Clamp Nuts must be slightly loose,to
tension the chain correctly.
1. Hold the tip of the Guide Bar up and turn the
_djusting Screw just until the chain does not
sag beneath the Guide Bar.Figure 14.
NOTE: Turn screw clockwise to tighten ten-
sion. Turn screw counterclockwise to loosen
tension.
3. Continue turning the Adjusting Screw until
the tension is correct.
4. Hold the tip of the Guide Bar up and tighten
the Bar Clamp Nuts with the Scrench.

F. ENGINE FUEL MIXTURE
• Your chain saw ispowered bya two-cycle engine
which requires a fuel mixture of regular,
unleaded gasoline and a high quality engine oil
specially made for 2-cycle, air-cooled engines.
The internaldesign of the 2-cycle engine requires
lubricationof moving parts. Lubricationis provided
when youusethe recommended mixtureofgasoline
and oil.
Gasoline must be clean and not over two
months old. After a short period of time,
gasoline begins to chemically break down
and will form compounds that can cause hard
starting and damage in 2-cycle engines.
• The correct measure of gasoline to oil is very
important.
--Too much oil in the mixture will foul the
spark plug.
--Too little oil will cause the engine to over-
heat resulting in damage.
• Mix the fuel thoroughly in a container since
gasoline and oil do not readily combine. Do not
try to mix fuel directly inthe fuel tank.
Rgure 15
1. USETHE FOLLOWING FUEL MIXTURES:
2. DO NOT USE:
• BIA Oil (Boating Institute of America)
--Does not have proper additives for air-
cooled, 2-cycle engines and could cause
damage.
• AUTOMOTIVE OIL-
- Does not have proper additives for 2-cycle
engines and could cause damage.
• GASOLINE CONTAINING ALCOHOL-
(High Test, Premium or Gasohol)
-- Stiffens critical carburetor fuel metering ele-
ments and causes engine damage from
overheating.
-- Increases vapodock (causes hard starting).
-- Attracts water causing corrosion damage.
9
3. HOW TO MIX FUEL 4. IMPORTANT POINTS
a. Pour one-half of the gasoline into an ap-
proved, marked container. Do not try to mix
oil and gasoline directly in the fuel tank.
b. Add entire measure of 2-cycle Engine Oil.
c. Mix.
d. Add remainder of gasoline.
e. Mix thoroughly for one minute.
Figure 16
G. BAR AND CHAIN OIL
• The guide bar and cutting chain require con-
tinuous lubrication in order to remain in
operating condition. Lubrication is provided
by the automatic oiler system when the oil
tank is kept filled.
--Lack of oil will quickly ruin the bar and
chain.
--Too little oil will cause overheating shown
by smoke coming from the chain and/or
discoloration of the guide bar rails.
• Use Sears Bar and Chain Lubricant #71-36554
or clean SAE 30W oil.
• In freezing weather oil will thicken, making it
necessary to thin bar and chain oil with a
sm_ill amount of Diesel Fue! #1 or Kerosene.
Bar and chain oil must be free flowing for the
oil system to pump enough oil for adequate
lubrication.
a. Use only recommended fuel mixtures.
b. Eliminate all soumes of sparks or flame inthe
areas where fuel is mixed, poured, or stored.
Thereshouldbe nosmoking,openflames orwork
thatcouldcause sparks.
c. Usean approved, marked container for all fuel
purposes.
d. Mix and pour fuel In an outdoor area on bare
ground. Store fuel in a cool, dry, well-
ventilatedplace. Gasolinevaporsare harmfulto
your healthand are a seriousfire hazard. Use a
funnel or spoutwhen pouringfuel.
e. Avoid overfilling the fuel tank. Allow3/4inchfor
expansion.Tighten FuelCap securely.Figure16.
f. Wipe up all fuelspllls. Wipooffanyfuel spilledon
thesaw.Completelydry thesaw before using.
g. Move at least 10feet(3 meters) away from fuel
_nd fueling site before starting the engine.
1. USE THE FOLLOWING:
3O°F or above -- Lubricant -- undiluted.
30°F - O°F -- 95% lubricant to 5% Diesel
Fuel #1 or Kerosene.
Below 0°F -- 90% lubricant to 10%
Diesel Fuel #1 or Kerosene.
2. HOW TO FILL THE OIL TANK
a. Stop the engine.
b. Turn saw on its side with oil cap up. Figure
17.
c. Loosen cap slowly and wait for pressure in

3. IMPORTANT POINTS TO REMEMBER
a. Fill the oil tank each time you refill the fuel
tank to ensure there will be sufficient oil for
the chain whenever you start and run the
saw.
b. The saw will use about 1/2 tank of chain oil
for each tank of fuel mixture. If less oil is
used, check for a plugged oil hole in the
guide bar.
c. It is normal for a small amount of oil to ap-
pear under the saw after the engine stops.
This is due to oil draining from the bar and
chain when not in use.
