OPERATE YOUR SAW SAFELY
Do not operate a chain saw with one hand.
Serious injury to the operator, helpers, by- standers or any combination of these per- sons may result from one-handed opera- tion. A chain saw is intended for two-handed use.
Operate the chain saw only in a wetbventi-
lated outdoor area.
Do not operate saw from a ladder or in a
tree.
MakesurethechainwiH not makecontact
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 at the end
of the cut. Applying pressure can cause you to lose control when the cut is com-
pleted.
Stop the engine before setting the saw
down.
Do not operate a chain saw that is dam-
aged, improperly adjusted, or not com- pletely and securely assembled. Always replace bar, chain, hand guard, or chain
brake immediately if it becomes damaged, broken or is otherwise removed.
With the engine stopped, hand carry the
chain saw with the muffler 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 listed in the maintenance sec-
tion oftMs manual. Forexample, if improp- er tools are used to remove or hold the fly-
wheel when servicing the clutch, structura] damage to the flywheel can occur and
cause the flywheel to burst.
Make certain the saw chain stops moving
when the throttle trigger is released. For correction, refer to CARBURETOR AD_ JUSTMENTS.
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,_'; accessories and re-
placement parts as recommended.
HANDLE FUEL WITH CAUTION
Do not smoke while handling 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, orworkthat 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 1g feet (3 meters) from fuel- ing site before starting engine.
Turn the engine off and let saw coo] in a non-combustible area, not on dry leaves,
straw, paper, etc. Slowly remove fuel cap and refuel unit.
Storethe unit and fuetin an area wherefuel
vapors cannot reach sparks or open flames from water heaters, electric motors
or switches, furnaces, etc.
KICKBACK
,_WARNING: Avoid kickback which
can result in serious injury. Kickback is the backward, upward or sudden 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 log or branch, or when the wood closes in and pinches the
saw chain in the cut. Contactfl/g a foreign ob- ject in the wood can also result in loss 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 into 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-Kickbackcan 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.
Pull-In can occur when the moving chain contacts a foreign object in the wood in the
cut alcng the bottom of the guide bar and the saw chatn is suddenly stopped. This sudden
stopping pulls the saw forward and away
from the operator and could easily cause the
operator to lose contrc4 of the saw.
Avoid Pinch-Kickback:
Be extremely aware of situations or ob- structions that ca n ca use 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 cutting 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 surpbse
which contributes to accidents.
Never let the moving chain 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. Eliminate 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 maintenanceinstructions. Checkten- sion at regular intervals with the engine
stopped, never with the engine running. Make sure the chain brake nuts are se-
curely tightened after tensioning the chain.
Begin and continue cutting at full speed, if the chain is moving at a slower speed,
there is greater chance of kickback occur- ring.
Cut one log at a time.
Use extreme caution when re-entering a previous cut.
Do not attempt cuts starting with the tip of the bar (plunge cuts).
Watch for shifting logs or other forces that could close a cut and pinch or fall into chain.
Use the Reduced-Kickback Guide Bar and Low-Kickback Chain specified for
your saw.

Keep a good, firm grip on the saw with both hands when the engine is running and
don't let go. A firm grip will help you reduce kickback and maintain control of the saw.
Keep the fingers of your left hand encir- cling and your left thumb under the front
handlebar. Keep your right hand com- pletely around the rear handle whether
your are right handed or left handed. Keep your left arm straight with the elbow
locked.
Position your left hand on the front handle- bar so it is in a straight line with your right
hand on the rear handle when making bucking cuts. Never reverse right and left
hand positions for any type of cutting.
Stand with your weight evenly balanced on both feet.
Stand slightly to the ]eft 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.

KICKBACK SAFETY FEATURES
_ WARNING: The followingfeatures
are included on your saw to help reduce the hazard of kickback; however, such features
will not totally eliminate this danger As a chain saw user, do not re{y only on safety de-
vices. You must follow all safety precau- fions, instructions, and maintenance in this manua{ to help avoid kickback and other
forces which can result in serious injury.
Reduced-Kickback Guide Bar, designed
with a smalJ 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.

action may push the guide bar rapidly back toward the operator. Either of these events
may cause you to lose controt 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. Re-
duced-kickback guide bars and low-kick- back saw chains reduce the chance and
magnitude of kickback and are recom- mended. Your saw has a low kickback chain
and bar as original 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 ser- vicing dealer, or to the nearest authorized master service dealer.
T_pcontact in some cases may cause a light- ning fast reverse REACTION, kicking the
guide bar up and back toward the 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 controt of the saw which could result
in serious injury.Do not rely exclusively upon the safety devices built into your saw.
,1_ WARNING: Computed kickback
angle (CKA) listed on your saw and listed in the CKA table below represents angie of
kickback your bar and chain combinations will have when tested in accordance with
CSA and ANSI standards. When purchasing replacement bar and chain, considerations
should be given to the lower CKA values. Lower CKA values represent safer angles to
the user, higher values indicate more angle and higher kick energies. Computed angles
represented in the non-activated cotumn in- dicate total energy and angle associated
without activation of the chain brake during kickback. Activated angle represents chain
stopping time relative to activation angle of chain brake and resulting kick angle of saw. In all cases lower CKA values represent a
safer operating environment for the user. The following guide bar and chain combina-
tions meet kickback requirements of CSA Z62.1, Z62.3, & ANSI B175.1 when used on
saws listed in this manual. Use of bar and chain combinations other than those listed is
not recommended and may not meet the CKA requirements per standard.

FUELING ENGINE
This engine is certified to operate on unleaded 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 is
recommended. A 40:1 ratio is obtained by mixing 3.2 ounces (95 m0 ofoil with 1 gallon (4
liters) of unleaded gasotine. Included with this saw is a 3.2 ounce container of Poulan/Weed
Eater brand synthetic oil. Pour the entire
contents of this container into 1 gallon of gasoline to achieve the proper fuel mixture.
DO NOT USE automotive or boatoil. These oils will cause engine damage. When mixing fuel fotlow the instructions printed on the
container. Always read and follow 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 will quickly ruin the bar and chain. Too little oil will cause overheatin
shown by smoke coming from the chain and7 or discoloration of the bar.
In freezing weather oil will thicken, making it necessary to thin bar and chain oil with a
small 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 oil for adequate lubrication. Genuine Poulan_; bar and chain oil is
recommended to protect your unit against excessive wear from heat and friction.
Poulan®_ oil resists high temperature thinning, tfPouian_) barandchainoilisnot available, 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
Experience indicates that alcohol-blended fuels (called gasohol or using ethanol or
methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel
system of an engine while in storage. To avoid engine problems, the fuel system
should be emptied before storage for 30 days or longer. Drain thegns tank, start the engine and let it run until the fuel lines and
carburetor are empty. Use fresh fuel next season. See STORAGE section for addi-
tional information.
,mbWARNING: 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 burns. To stop the engine move the ON/STOP
switch to the STOP position. To start the engine hold the saw firmly on the
ground as illustrated. Make sure the chain is free to turn without contacting any object.
Use only 15 - 18 inches (38 - 45 cm) of rope per pull.
Hold saw firmiy while pulling starter rope.

1-500-554-6723.
CHAIN BRAKE
,_kWARNING: If the brake band is
worn too thin it may break when the chain brake is triggered. With a broken brake band,
the chain brake will not stop the chain. The chain brake should be replaced by an autho-
rized service dealer if any part is worn to less than 0.020" (0.5 ram) thick. Repairs on a
chain brake should be made by an autho- rized service dealer. Take your unit to the
place of purchase if purchased from a ser- vicing dea]eh or to the nearest authorized rnaster service dealer.
This saw is equipped with a chain brake.
The brake is designed to stop the chain if kickback occurs.
The inertia-activated chain brake is
activated if the front hand guard is pushed forward, either manually (by hand) or
automatically (by sudden movement).
If the brake is already activated, it is
disengaged by pulling the front hand guard back toward the front handle as far as
possible.
When cuttthg with the saw, the chain brake
must be disengaged.

brake should activate.
IMPORTANT POINTS
Check chain tension before first use and after I minute of operation. See CHAIN
TENSION in the ASSEMBLY section.
Cut wood only. Do not cut metat, plastics, masonry, non-wood building materials, etc.
Stop the saw if the chain strikes a foreign object, thspect the saw and repair or re-
place parts as necessary.
Keepthechain out of dirt and sand. Even a small amount of dirt will quickly bah a chain
and thus increase the possibility of kickback.
Practice cutting a few small logs using the
following techniques to get the "feeF of us-
ing your saw before you begin a major sawing operation.
Squeeze the throttle trigger and allow
the engine to reach full speed before cutting.
Begin cutting with the saw frame
against the log.
Keep the engine at full speed the entire
time you are cutting.

Release the throttle trigger as soon as the cut is completed, allowing the en-
gine to idle. If you run the saw at full throttle without a cuttthg load, 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 losing controlwhen 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
_I_WARNING: Check for broken or
dead branches which can fall while cutting causing serious injury. Do not cut near bui_d-
thgs or electrical wires Jfyou do not know the direction oftreefall, norcut at night since you
will not be ale to see well, nor during bad weather such as rain, snow, or strong winds,
etc. If the tree makes contact with any utility line, the utility company should be notified
immediately.
Carefully plan your sawing operation in ad- vance.
Cleartheworkarea. You needacleararea all around the tree so you can have secure footing.
Study the natural conditions that can cause the tree to fall in a pedicular direction.
Natural conditions that can cause a tree to
fall 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
sloping terrain. Use a ptumb or level to de- termine the direction of tree _ean.
Weight and branches on one side.
Surrounding trees and obstacles.
Look for decay and rot. tfthe trunk is rolled, it can snap and fatl toward the operator. Check for broken or dead branches which can fail on
you while cL_ting.
Make sure there is enough room for the tree to fall. Maintath a distance of 2-1/2 tree lengths from the nearest person or other objects. En-
gine nc4se can drown out a warnthg call.
Remove dirt, stones, loose bark, nails, staples, and wire from the tree where cuts are to be
made.
Plan a clear retreat path to the rear and diag- onal to the line of fall.

FELLING LARGE TREES (6 inches (15 cm) in diameter or targer)
The notch method is used to fell large trees. A notch is cut on the side of the tree in thede-
sired direction of fall. After a felling cut is made on the opposite side of tree, the tree
will tend to fall into the notch. NOTE: If the tree has large buttress roots,
remove them before making the notch. If 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 notch first. Cut through 1/3 of the diameter
ofthetree. Next complete the notch bycut-
ting the bottom of the notch. See illustra- tion. Once the notch is cut remove the
notch of wood from the tree.
Final felling cut here, 2 inches
5 cm above center o notch.

Notch _
Second cut_
After removing the cutout of wood, make
the felling cut on the opposite side of the
notch. This is done by making a cut about
twoinches (5 cm) higher than the center of the notch. This will leave enough uncut
wood between the felli ng cut and the notch to form a hinge. This hinge will help pre-
vent the tree from falling in the wrong direc- tion.
Hinge holds tree on stump and helps control fall
Closing of notch
NOTE: Before felling cut is complete, use wedges to open the cut when necessary to
controtthedirection of fall. To avoid kickback and chain damage, use wood or plastic
wedges, but never steel or iron wedges.
Be alert to signs that the tree is ready to falh cracking sounds, widening of the felling cut,
or movement in the upper branches.
As tree starts to fall, stop saw, put Jtdown, and get away quickly on your planned re-
treat path.
