SAFETY RULES

WARNING: Always disconnect

spark plug wire and place wire where it can-

not contact spark plug to prevent accidental

starting when setting up, transporting, ad-

justing or making repairs except carburetor

adjustments.

Because a chain saw is a high-speed wood-

cutting tool, special safety precautions must

be observed to reduce the risk of accidents.

Careless or improper use of this tool can

cause serious injury.

PLAN AHEAD

SRead this manual carefully until you com-

pletely understand and can follow all safety

rules, precautions, and operating instruc-

tions before attempting to use the unit.

SRestrict the use of your saw to adult users

who understand and can follow safety

rules, precautions, and operating instruc-

tions found in this manual.

SWear protective gear. Always use steel-toed

safety footwear with non-slip soles; snug-fit-

ting clothing; safety chaps; heavy-duty, non-

slip gloves; eye protection such as non-fog-

ging, vented goggles or face screen; an

approved safety hard hat; and sound barri-

ers (ear plugs or mufflers) to protect your

hearing. Regular users should have hearing

checked regularly as chain saw noise can

damage hearing. Secure hair above shoul-

der length.

SKeep all parts of your body away from the

chain when the engine is running.

SKeep children, bystanders, and animals a

minimum of 30 feet (10 meters) away from

the work area. Do not allow other people

or animals to be near the chain saw when

starting or operating the chain saw.

SDo 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 aggravated by strenuous work,

check with your doctor before operating a

chain saw.

SCarefully plan your sawing operation in ad-

vance. Do not start cutting until you have a

clear work area, secure footing, and, if you

are felling trees, a planned retreat path.

OPERATE YOUR SAW SAFELY

SDo 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.

SOperate the chain saw only in a well-venti-

lated outdoor area.

SDo not operate saw from a ladder or in a

tree.

SMake 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.

SDo 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.

SStop the engine before setting the saw

down.

SDo 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.

SWith 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

SHave all chain saw service performed by a

qualified service dealer with the exception

of the items listed in the maintenance sec-

tion of this manual. For example, if improp-

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.

SMake certain the saw chain stops moving

when the throttle trigger is released. For

correction, refer to CARBURETOR AD-

JUSTMENTS.

SNever modify your saw in any way.

SKeep the handles dry, clean, and free of oil

or fuel mixture.

SKeep fuel and oil caps, screws, and fas-

teners securely tightened.

SUse only Poulan PRO accessories and

replacement parts as recommended.

HANDLE FUEL WITH CAUTION

SDo not smoke while handling fuel or while

operating the saw.

SEliminate all sources of sparks or flame in

the areas where fuel is mixed or poured.

There should be no smoking, open flames,

or work that could cause sparks. Allow en-

gine to cool before refueling.

SAlways have fire extinguishing tools avail-

able if you should need them.

SMix 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.

SMove at least 10 feet (3 meters) from fuel-

ing site before starting engine.

STurn the engine off and let saw cool in a

non-combustible area, not on dry leaves,

straw, paper, etc. Slowly remove fuel cap

and refuel unit.

SStore the unit and fuel in an area where fuel

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 the guide bar contacts any

object such as a log or branch, or when the

wood closes in and pinches the saw chain in

the cut. Contacting a foreign object in the wood

can also result in loss of chain saw control.

SRotational 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.

SPinch-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.

SPull-In 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:

SBe extremely aware of situations or ob-

structions that can cause material to pinch

the top of or otherwise stop the chain.

SDo not cut more than one log at a time.

SDo not twist the saw as the bar is with-

drawn from an undercut when bucking.

Avoid Pull--In:

SAlways begin cutting with the engine at full

speed and the saw housing against wood.

SUse wedges made of plastic or wood.

Never use metal to hold the cut open.

void Obstructions

Clear The Working Area

REDUCE THE CHANCE OF

KICKBACK

SRecognize that kickback can happen.

With a basic understanding of kickback,

you can reduce the element of surprise

which contributes to accidents.

SNever let the moving chain contact any ob-

ject at the tip of the guide bar.

SKeep 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.

SKeep 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 chain brake nuts are se-

curely tightened after tensioning the chain.

SBegin and continue cutting at full speed. If

the chain is moving at a slower speed,

there is greater chance of kickback occur-

ring.

SCut one log at a time.

SUse extreme caution when re-entering a

previous cut.

SDo not attempt cuts starting with the tip of

the bar (plunge cuts).

SWatch for shifting logs or other forces that

could close a cut and pinch or fall into chain.

SUse the Reduced--Kickback Guide Bar

and Low--Kickback Chain specified for

your saw.

MAINTAIN CONTROL

SKeep 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.

SPosition 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.

SStand with your weight evenly balanced on

both feet.

SStand slightly to the left side of the saw to

keep your body from being in a direct line

with the cutting chain.

SDo not overreach. You could be drawn or

thrown off balance and lose control of the

saw.

SDo not cut above shoulder height. It is diffi-

cult to maintain control of saw above

shoulder height.

KICKBACK SAFETY FEATURES

WARNING: The following features

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 rely only on safety de-

vices. You must follow all safety precau-

tions, instructions, and maintenance in this

manual to help avoid kickback and other

forces which can result in serious injury.

SReduced--Kickback Guide Bar, 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.

SPosition of front and rear handlebars, de-

signed with distance 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

SChain Brake, designed to stop the chain in

the event of kickback.

WARNING: WE DO NOT REP-

RESENT AND YOU SHOULD NOT AS-

SUME THAT THE CHAIN BRAKE WILL

PROTECT YOU IN THE EVENT OF A

KICKBACK. Kickback is a lightning fast ac-

tion 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 the danger zone with any hard object.

Kickback can also be caused by pinching the

saw chain along the top of the guide bar. This

action may push the guide bar rapidly back

toward the operator. 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. 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.

STip contact in some cases may cause a

lightning fast reverse REACTION, kicking

the guide bar up and back toward the oper-

ator.

SPinching the saw chain along the top of the

guide bar may push the guide bar rapidly

back toward the operator.

SEither of these reactions may cause you to

lose control of the saw which could result

in serious injury.Do not rely exclusively

upon the safety devices built into your saw.

WARNING: 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 with

CSA (Canadian Standards Association) and

ANSI standards. When purchasing replace-

ment 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 rep-

resented in the non-activated column indi-

cate total energy and angle associated with-

out 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.

SIf chain is too loose, it will sag below the

guide bar. DO NOT operate the saw if the

chain is loose.

NOTE: The chain is tensioned correctly when

the weight of the chain does not cause it to sag

below the guide bar (with the chain saw sitting

in an upright position), but the chain still moves

freely around the guide bar.

WARNING: If the saw is operated

with a loose chain, the chain could jump off the

guide bar and result in serious injury to the op-

erator and/or damage the chain making it un-

usable. If the chain jumps off the guide bar, in-

spect each drive link for damage. Damaged

chain must be repaired or replaced.

provides additional fuel to the engine during

cold starting.

CHAIN BRAKE

The CHAIN BRAKE is a device designed to

stop the chain if kickback occurs. The chain

brake activates automatically in the event of

kickback. The chain brake activates manu-

ally if the front hand guard is pushed forward.

The chain brake is disengaged by pulling the

front hand guard back toward the front han-

dle as far as possible.

CHAIN TENSION

It is normal for a new chain to stretch during

first 15 minutes of operation. You should check

your chain tension each time before you start

thechainsaw.SeeCHAINTENSIONinthe

ASSEMBLY section.

WARNING: If the saw is operated

with a loose chain, the chain could jump off

the guide bar and result in serious injury to

the operator and/or damage the chain mak-

ing it unusable.

BEFORE STARTING ENGINE

WARNING: Muffler is very hot dur-

ing and after use. Do not touch the muffler or

allow combustible material such as dry

grass or fuel to do so.

WARNING: Be sure to read the fuel

handling information in the safety rules sec-

tion of this manual before you begin. If you do

not understand the fuel handling information

do not attempt to fuel your unit. Seek help

from someone that does understand the in-

formation or call the customer assistance

help line at 1-800-554-6723.

FUELING ENGINE

WARNING: Remove fuel cap slow-

ly when refueling.

HELPFUL TIP

To obtain the correct oil mix

ratio, pour 3.2 ounces of

2--cycle synthetic oil into

one gallon of fresh gas.

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. Mix

gasoline and oil at a ratio of 40:1. A 40:1 ratio is

obtained by mixing 3.2 fluid ounces of oil with 1

gallon of unleaded gasoline. Included with this

saw is a 3.2 ounce container of oil. Pour the

entire contents of this container into 1 gallon of

gasoline to achieve the proper fuel mixture. DO

NOT USE automotive oil or boat oil. These oils

will cause engine damage. When mixing fuel,

follow instructions printed on container. Once

oil is added to gasoline, shake container

momentarily to assure that the fuel is

thoroughly mixed. Always read and follow the

safety rules relating to fuel before fueling your

unit.

CAUTION: Never use straight gasoline in

your unit. This will cause permanent engine

damage and void the limited warranty.

FUEL REQUIREMENTS

This engine requires the use of minimum 87

octane [R+M]/2 clean gasoline.

IMPORTANT

Use of alcohol blended fuels (called gasohol or

using ethanol or methanol) can cause major

engine performance and durability problems.

WARNING: Alternative fuels (not

gasoline) such as E--15 (15% alcohol), E--20

(20% alcohol), E--85 (85% alcohol) are NOT

classified as gasoline and are NOT approved

for use in 2--stroke gasoline engines. Use of al-

ternative fuels will cause problems such as: im-

proper clutch engagements, overheating, va-

por lock, power loss, lubrication deficiency,

deterioration of fuel lines, gaskets and internal

carburetor components, etc. Alternative fuels

cause high moisture absorption into the fuel/oil

mixture leading to oil and fuel separation.

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 overheating

shown by smoke coming from the chain and/

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 or Poulan PRO bar and

chain oil is recommended to protect your unit

against excessive wear from heat and

friction. Poulan or Poulan PRO oil resists

high temperature thinning. If Poulan or

Poulan PRO bar and chain oil is not

available, use a good grade SAE 30 oil.

SNever use waste oil for bar and chain lubri-

cation.

SAlways stop the engine before removing

the oil cap.

CHAIN BRAKE

Ensure chain brake is disengaged by pulling

the front hand guard back toward the front han-

dle 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 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.

Hold saw firmly while pulling starter rope.

Use only 15”---18” of rope per pull.

the operator at risk of serious injury due to

loss of control of the chain saw.

IMPORTANT POINTS TO REMEMBER

When pulling the starter rope, do not use the full

extent of the rope as this can cause the rope to

break. Do not let starter rope snap back. Hold

the handle and let the rope rewind slowly.

For cold weather starting, start the unit at

FULL CHOKE; allow the engine to warm up

before squeezing the throttle trigger.

NOTE: Do not cut material with the choke/

fast idle lever at the FULL CHOKE position.

HELPFUL TIP

If your engine still does not

start after following these

instructions, please call

1--800--554--6723.

STARTING A COLD ENGINE (or warm

engine after running out of fuel):

NOTE: In the following steps, when the

choke/fast idle lever is pulled out to the full

CHAIN BRAKE

WARNING: 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 authorized service

dealer if any part is worn to less than 0.020″

(0.5 mm) thick. Repairs on a chain brake

should be made by an authorized service deal-

er. Take your unit to the place of purchase if

purchased from a servicing dealer, or to the

nearest authorized master service dealer.

SThis saw is equipped with a chain brake.

The brake is designed to stop the chain if

kickback occurs.

SThe inertia--activated chain brake is

activated if the front hand guard is pushed

forward, either manually (by hand) or

automatically (by sudden movement).

SIf the brake is already activated, it is

disengaged by pulling the front hand guard

back toward the front handle as far as

possible.

SWhen cutting with the saw, the chain brake

must be disengaged.
