OPERATE YOUR SAW SAFELY
Do not operate a chain saw w_th one hand Serious injury to the operator, helpers, by-
standers or any combination of these per- sons may result from one-handed operation
A chain saw is intended for two-handed use
Operate the chain saw only in a welFventi- Iated outdoor area.
Do not operate saw from a ladder or in a tree
Make sure the chain will not make contact with any object while starting the engine.
Never try to start the saw when the guide bar is in a cut.
Do not put pressure on the saw atthe end of
the cut Applying pressure can cause you to
lose control when the cut is completed.
Stop the engine before setting the saw down.
Do not operate a chain saw that is dam- aged, improperly adjusted, or not com-
pIetely and securely assembled. Always rep}ace bar, chain, hand guard, or chain brake immediately ifit becomes damaged, broken or is otherwise removed.
With the engine stopped, hand carry the chain saw with the muffier away from your
body, and the guide bar and chain to the rear. preferably covered with a scabbard
MAINTAIN YOUR SAW IN GOOD WORKING ORDER
Have all chain saw service performed by a qualified service dealer with the exception of the items tisted in the maintenance sec-
tion ofthis manual For example, ifimprop-
er tools are used to remove or hold the fly- wheel when servicing the clutch, structural damage to the flywheel can occur and
cause the flywheel to burst.
Make certain the saw chain stops mowng when the throttle trigger is released. For correction, refer to CARBURETOR AD-
JUSTMENT.
Never modify your saw in any way
Keep the handles dry, clean, and free of oil or fuel mixture.
Keep fuel and oil caps, screws, and fas- teners securely tightened.
Use only Poulan PRO accessories and re- placement parts as recommended.
HANDLE FUEL WITH CAUTION
Do not smoke while handIing fuel or while operating the saw.
Eliminate all sources of sparks or flame in
the areas where fuel is mixed or poured. There should be nosmoking, open flames,
or work that could cause sparks. Allow en- gine to cool before refueling.
Mix and pour fuel in an outdoor area on bare ground; store fuel in a cool, dry, well
ventilated place; and use an approved, marked container for all fuel purposes.
Wipe up all fuel spills before starting saw
Move at least fOfeet (3 meters) from fuel- ing site before starting engine.
Turn the engine off and let saw cool in a non-combustible area, not on dry _eaves,

KICKBACK
WARNING: Avoid kickback which
can result in serious injury Kickback is the backward, upward orsudden forward motion
of the guide bar occurring when the saw chain near the upper tip of theguide bar con-
tacts any object such as a fag or branch, or when the wood cfases in and pinches the
saw chain in the cut. Contacting a foreign ob- ject in the wood can also result in fass of chain saw control
Rotational Kickback can occur when the moving chain contacts an object at the up-
per tip of the guide bar. This contact can cause the chain to dig fato the object,
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
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 to move in the opposite direction of the chain rotation. The saw is driven straight
back toward the operator.
Pull4n can occur when the moving chain contacts a foreign object 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:
Be extremely aware of situations or ob- structions that can cause material to pinch the top of or otherwise stop the chain.
Do not cut more than one log at a time
Do not twist the saw as the bar is with- drawn from an undercut when bucking.
Avoid Pull-In:
Always begin cuttfag with the engine at full speed and the saw housing against wood.
Use wedges made of plastic or wood. Never use metal to hold the cut open
REDUCE THE CHANCE OF KICKBACK
Recognize that kickback can happen With a basic understanding of kickback,
you can reduce the element of surpdse which contributes to accidents.
Never Ietthe moving chah contact any ob-
ject at the tip of the guide bar.
Keep the working area free from obstruc- tions such as other trees, branches, rocks,
fences, stumps, etc. EIiminate or avoid
any obstruction that your saw chain could hit while you are cutting. When cutting a
branch, do not let the guide bar contact branch or other objects around it.
Keep your saw chain sharp and properly
tensioned. A loose or dull chain can in-
crease the chance of kickback occurring. Follow manufacturer's chain sharpening
and maintenance instructions. Check ten- sion at regular intervals with the engine
stopped, never with the engine running Make sure the bar nuts are securely tight-
ened after tensioning the chain.
Begin and continue cutting at ful} speed. If the chain is moving at a slower speed, there
_sgreater chance of kickback occurring.
Cut one fag at a time
Use extreme caution when re-entering a previous cut.
Do not attempt cuts starting with the tip of
the bar (p_unge cuts).
Watch for shifting logs or other forces that could cIose a cut and pinch or fall into chain
Use the Reduced-Kickback Guide Bar and Low-Kickback Chain specified for
your saw.

Stand with your weight evenly balanced on both feet.
Stand slightly to the left side of the saw to keep your body from being in a direct line
with the cutting chain.
Do not overreach. You could be drawn or thrown off balance and lose control of the
saw.
Do not cut above shoulder height, it is diffi- cuSt to maintain control of saw above
shoulder height.
KICKBACK SAFETY FEATURES
,li_ WARNING: Thefollowingfeatures
are included on your saw to help reduce the hazard of kickback; however, such features
wilt not totalty eliminate this danger. As a chain saw user, do not rely only on safety de-
vices. You must follow alt safety precau- tions, instructions, and maintenance in this
manuaI to help avoid kickback and other forces which can resuIt in serious injury.
Reduced-Kickback Guide Ba£ designed with a small radius tip which reduces the
size of the kickback danger zone on the bar tip. A Reduced-Kickback Guide Bar has been demonstrated to significantly re- duce the number and seriousness of kick- backs when tested in accordance with
safety requirements for gasoline powered chain saws as set by ANSI B175.1
ReducedKickbackSymmetricalGuideBar
Low-Kickback Chain, designed with a contoured depth gauge and guard link
which deftect kickback force and allow wood to gradually ride into the cutter Low-
Kickback Chain has met kickback per- formance requirements when tested on a
representative sampte of chain saws be- low 3.8 cubic inch displacement specified in ANSI 8175.1

Front Hand Guard, designed to reduce the chance of your left hand contacting the chain
if your hand slips oft the front handlebar.
Position of front and rear handlebars, de- signed w_thdistance between handles and
"in-line" with each other. The spread and "in-line" position of the hands provided by
this design work together to give balance
and resistance in controlling the pivot of
the saw back toward the operator if kick-
back occurs.
CHAIN BRAKE AND CKA ANGLE

nlo cutter
,_I_WARNING: WE DO NOT REP-
RESENT AND YOU SHOULD NOT AS- SUME THAT THE CHAIN BRAKE WILL
PROTECT YOU IN THE EVENT OPA KICK- BACK. Kickback is a lightning fast action
which throws the bar and rotating chain back and up toward the operator. Kickback can be
caused by allowing contact of the bar tip in time danger zone with any hard object Kickback
can also be caused by pinching the saw chain along the top of the guide baE This action may push the guide bar rapidly back toward the op-
erator. Either of these events may cause you to lose control of the saw which could result in
serious injury or even death. DO NOT RELY UPON ANY OF THE DEVICES BUILT iNTO
YOUR SAW. YOU SHOULD USE THE SAW PROPERLY AND CAREFULLY TO AVOID KICKBACK. Reduced-kickback guide bars
and low-kickback saw chains reduce the chance and magn_ude of kickback and are
recommended. Your saw has a low kickback chain and bar as edgina_ equipment. Repairs
on a chain brake should be made by an autho- rized servicing dealer. Take your unit to the place of purchase if purchased from a servic-
ing dealer, or to the nearest authorized master service dealer.
_p contact insome cases may cause a light- ning fast reverse REACTION, kicking guide
bar up and back toward operator.
Pinching the saw chain along the top of the guide bar may push the guide bar rapidly
back toward the operator
Either of these reactions may cause you to lose control of the saw which could result in
serious injury. Do not rely exc}usively upon devices built into your saw.
_ILWARNING: Computed kickback
angle (CKA) listed on your saw and listed in the CKA table below represents angle of kickback
your bar and chain combinations will have when tested in accordance w_h CSA (Cana-
dian Standards Association) and ANSI stan- dards. When purchasing replacement bar and
chain, considera_ons shouid be given to the lower CKA values. Lower CKA values repre-
sent safer angles to the user, higher values in- dicate more angle and higher kick energies. Computed angles represented indicate total
energy and angle associated without activation

FUELING ENGINE
_lJ WARNING: Remove fuel cap slow- ly when refue}ing.
This engine is certified to operate on un- leaded gasoline Before operation, gasoline
must be mixed with a good quality synthetic 2-cycle air-cooled engine oil designed to be
mixed at a ratio of 40:1. Poulan/WEED
EATER brand synthetic oil _s recom-
mended. A 40:1 ratio is obtained by mixing
3.2 ounces (95 mb of oil with 1 gallon (4Irters) of unleaded gasoline included with this saw
is a 3.2 ounce (95 ml) container of Poulan/ WEED EATER brand synthetic oil Pour the
entire contents of this container into f gallon (4 liters) of gasoline to achieve the proper fuel
m_xture.
DO NOT USE automotive or manne oil.
These oils will cause engine damage. When mixing fuel follow the instructions printed on the container. Always read and fo}low the
safety rules listed under HANDLE FUEL WITH CAUTION.
BAR AND CHAIN LUBRICATION
The bar and chain require continuous lubri- cation. Lubrication is provided by the auto-
matic oiler system when the oil tank is kept filled. Lack of oil wJII quickly ruin the bar and chain. Too little oil will cause overheating
sbewn by smoke coming from the chain and/ or discolorapen of the bar.
In freezing weather oil will thicken, making it
necessary to thin bar and chain oiI with a smafl amount (5 to 10%) of #1 Diesel Fuel or kerosene Bar and chain oil must be free
flowing for the oil system to pump enough oiI for adequate lubdcation.
Genuine Poutan or Poulan PRO bar and chain oil is recommended to protect your unit against excessive wear from heat and fric-
tion. Poulan or Poulan PRO oil resiets high temperature thinning.
If Poulan or Poulan PRO bar and chain oilis
not availabIe, use a good grade SAE 30 oil.
Never use waste oil for bar and chain lubri- cation.
Always stop the engine before removing the oil cap.
IMPORTANT
Expebence indicates that aIcobel-blended
fuels (ca_led gasobel or using ethanol or meth-
ano/) can attract moisture which leads to sepa- rabon and formation of acids dudng storage
Acidic gas can damage the fuel system of an engine while in storage. To avoid engine prob- lems the fuel system should be emptied before
storage for 30 days or longer. Drain the gas tank, start the engine and let it run untiI the fuel
lines and carburetor are empty. Use fresh fuel next season See STORAGE section for addi-
tional informabon. CHAIN BRAKE
Ensure chain brake is disengaged by pulling the front hand guard back toward the front ben- die as far as possible. The chain brake must be
disengaged before cutting with the saw.
_,WARNING: The chain must not
move when the engine runs at idle speed. If the chain moves at idle speed refer to CAR-
BURETOR ADJUSTMENT within this manual. Avoid contact with the muffler. A hot
muffler can cause serious bums. To stop the engine move the ON/STOP switch to the STOP position. To start the engine beld the saw firmty on the
ground as illustrated Make sure the chain is free to turn without contacting any object
Use only 15" - 18" (40 - 45 cm) of rope per pull
Hold saw firmty while pulling starter rope.

should be pieced on the ground with the en- gine running.
Piece the saw on firm ground. Grip the rear handIe with your right hand and the front hen- die with your _efthand. Apply full throttle by
fully depressing the throttle trigger. Activate the chain brake by turning your left wrist
against the hand guard without releasing your grip around the front handle The chain should stop immediately

_I, WARNING: When performing the
following procedure, the engine must be turned off
Grip the rear handle w_th your right hand end the front handle with your ]eft hand. Hold the chain sew approximately tg" (35 cm) abovea
stump or other wooden surface. Release your grip on the front handle and use the weight of
the sew to let the tip of the guide bar fall forward and contact the stump When the tip of the bar
hits the stump, the brake should activate.

OPERATING TIPS
Check chain tension before first use and
after 1 minute of operation. See CHAIN TENSION in the ASSEMBLY section.
Cut wood onIy. Do not cut metal, plastics,
masonry, non-wood poilding materials, etc.
Stop the saw if the chain strikes a foreign
object, inspect the saw and repair or re- place parts as necessary.
Keep the chain out of dirt and send Even a
small amount of dirt will quickly dull a chain and thus increase the possibility of kickback.
Practice cutting a few small logs using the
folJowing techniques to get the "feel" of us- ing your saw before you begin a major
saw_ng operation.
Squeeze the thro_e trigger and allow the engine to reach fuII speed before cutting.
Begin cutting with the saw frame against the log.
Keep the engine at full speed the entire time you are cutting
Allow the chain to cut for you. Exert only light downward pressure. If you force the cut, damage to the bar, chain, or en-
gine can result.
Release the throttle trigger as soon as the cut is completed, allowing the en-
gine to idIe If you run the saw at full throttle without a cutting Ioad, unneces-
sary wear can occur to the chain, bar, and engine. It is recommended that
the engine not be operated for lon- ger than 30 seconds at full throttle.
To avoid Iosing control when cut is com- plete, do not put pressure on saw at end
of cut.
Stop the engine before setting the saw down after cutting.
TREE FELLING TECHNIQUES
,It_WARNING: Check for broken or
dead branches which can fall while cutting causing serious _njury. Do not cut near build-
ings or electrical wires if you do not know the direction of tree fall, nor cut at night since you
will not be ale to see welI, nor during bad weather such as rain, snow, or strong winds,
etc. Ifthetreemakes contact with any utility line, the utility company shouId be notified
immediately.
•CarefuIiy plan your sawing operation in ad- vance.
Cleartheworkarea Youneedacieararea all around the tree so you can have secure footing.
The chain saw operator should keep on the uphill side of the terrain as the tree is
likely to rol_or slide downhill after it is felled.
Study the natural conditions that can cause the tree to fali in a particular direction.
Natural conditions that can cause a tree to falI in a particular direction include:
The wind direction and speed.
The lean of the tree. The lean of a tree might not be apparent due to uneven or
sIoping terrain. Use a plumb or level to de- termine the direction of tree lean.
Weight and branches on one side
Surrounding trees and obstacles.
Look for decay and rot. If the trunk is rotted, it can snap and fall toward the operator
Check for broken or dead branches which can fail on you while cutting.
Make sure there is enough room for timetree to fall Maintain a distance of 2 1/2 tree lengths
from the nearest person or other objects. En- gine noise can drown out a warning call Remove dirt, stones, loose bark, nails, sta- ples, and wire from the tree where cuts are to
be made. P_an a clear retreat path to the rear and diag-
onal to the line of fail.

FELLING LARGE TREES (6 inches (t5 cm) in diameter or larger)
The notch method is used to fell large trees. A notch is cut on the side of the tree in the de-
sired direction of fall After a failing cut is made on the opposite side of tree, the tree
will tend to fail into the notch NOTE: If the tree has large buttress roots,
remove them before making the notch, tf us- ing saw to remove buttress roots, keep saw
chain from contacting ground to prevent dull- ing of the chain.
NOTCH CUT AND FELLING THE TREE
Make notch cut by cutting the top of the nctch first. Cut through 1/3 of the diameter of the tree. Next complete the notch by c ut-
ting the bottom of the notch. See illustra- tion. Once the notch is cut remove the
nctch of wood from the tree
Final (failing) cut here, 2 inches (5 cm) above center of notch.
Notch _ . =
First cut _1 -__f
After removing the wood from the notch, make the felling cut on the opposite side of
the notch. This is done by making a cut about
two inches (5 cm) higher than the center of the notch. This will leave enough uncut wood
between the felling cut and the notch to form a hinge. This hinge will help prevent the tree
from falting in the wrong direction
