WARNINGS AND SAFETY INSTRUCTIONS
(See Additional Safety Instructions throughout this Manual)
GUARD AGAINST KICKBACK
Kickback is a dangerous reaction that can lead to serious
injury. Do not rely on the presence of the chain brake to pro-
tect you against injury from kickback. Although it may appear
that the chain brake is stopping quickly, it still may not be fast
enough to provide protection in the event of kickback. As a
chain saw user. you must take special safety precautions to
help keep your cutting jobs free from accident or injury.
A KICKBACK WARNING
Contact at the upper portion of the tip of the guide bar
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
toward the operator. This is kickback. 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 in serious injury.
Avoid
Obstructions
Clear The
Working Area
Figure 3
REDUCE THE CHANCE OF KICKBACK
I. Recognize that kickback can happen. With a basic
understanding of kickback. you can reduce the ele-
ment of surprise which contributes to accidents.
- Never let the moving chain contact any object at
the tip of the guide bar. Figure 2.
. Keep the working area free from obstructions such
as other trees. branches. rocks. fences, stumps, etc.
Figure 3. Eliminate or avoid any obstruction that your
saw chain at the bar tip could hit while you are cut-
ting.
Keep your saw chain sharp and properly ten-
sioned. À loose or dull chain can increase the chance
of kickback. Check sharpness and tension at regular
intervals with the engine stopped. never with the
engine running. Make surc the bar clamp nuts are
securely tightened after tensioning the chain.
N
ad

—4-
5. Begin and continue cutting at full throttle, If the
chain is moving at a slower speed. there is greater
chance for kickback.
. Cut one log at a time.
Use extreme caution when re-entering a previous
cut.
Do not start cutting with the bar tip (plunge or
boring cuts).
9. Watch for shifting logs or other forces that could
close a cut and pinch or fall into chain.
10.Use the Reduced-Kickback Guide Bar and Low-
Kickback Chain specified for your saw.

CHAIN BRAKE
e A chain brake is:
— A device for stopping the chain when activated.
Figures 4 and 5.
— To be used only in an emergency. Do not use oth-
erwise except for testing or making adjustments.
e A chain brake will not:
— Prevent kickback.
— Work if it is not maintained properly. Check to
see if the brake works properly before every cutting
job. If the chain does not appear to stop instantly,

Keep a good, firm grip on the saw with both hands
when the engine is running and don’t let go. Figure
7. 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. Keep your left arm straight
with the elbow locked.
Position your left hand on the front handlebar so
it is in a straight line with your right hand on the
rear handle. Figure 7.
. Never reverse right and left hand positions for any
type of cutting. There are no left handed chain saws.
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 cut-
ting chain. Figure 7.
. 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 difficult to
maintain control of saw above shoulder height.

. Do not operate a chain saw that is damaged,
improperly adjusted, or not completely and
securely assembled.
Operate the chain saw only outdoors.
Do not operate saw from a ladder or in a tree.
Position all parts of your body away from the saw
chain when the engine is running.
Cut wood only. Do not use your saw to pry or shove
away limbs. roots, or other objects.
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 or kerf.
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.
. 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.
. Do not put pressure on the saw at the end of a cut.
Applying pressure 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
Have all chain saw service performed by a quali-
fied 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 fly-
wheel to burst.
. Keep fuel and oil caps, screws, and fasteners
securely tightened.
. Keep the handles dry, clean, and free of oil or fuel
mixture.
Make certain the saw chain stops moving when
the throttle trigger is released. For correction, refer
to “Carburetor Adjustments.”
Stop the saw if the chain strikes a foreign object.
Inspect the unit and repair or replace parts as necessary.
Never modify your saw in any way. Use only
attachments recommended by the manufacturer.
Always replace the handguard immediately if it
becomes damaged, broken, or removed.
CARRY AND STORE YOUR SAW SAFELY

>
>
Hand carry with the engine stopped, the muffler
away from your body, and the guide bar and chain
to the rear covered preferably with a scabbard.
. Before transporting 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.
. Empty the fuel tank before storing the tool. Use
the fuel left in the carburetor by starting the engine
and letting the engine run until it stops.
Store unit and fuel in a dry area out of the reach
of children. Do not store where fuel vapors can reach
sparks or an open flame from hot water heaters, elec-
tric motors or switches, furnaces, etc.
KICKBACK SAFETY FEATURES
Low-Kickback Chain, designed with a contoured
depth gauge and guard link which deflect kickback
force and allow wood to gradually ride into the cutter.
Figure 8. Low-Kickback Chain is a chain which has
met kickback performance requirements of American
National Standards Institute, Inc. (ANSI) B175.1
(Safety Requirements for Gasoline-Powered Chain
Saws) when tested on a representative sample of
chain saws below 3.8 cubic inch displacement speci-
fied in ANSI B175.1.
Reduced-Kickback Guide Bar, designed with a
small radius tip which reduces the size of the kickback
danger zone on the bar tip. Figure 8. A Reduced-
Kickback Guide Bar is one which has been demon-
strated to significantly reduce the number and serious-
ness of kickback when tested in accordance with
ANSI BI175.1.
Handguard, designed to reduce the chance of your
left hand contacting the chain if your hand slips off
the front handlebar.
Position of front and rear handlebars, designed
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 kickback occurs.
WARNINGS AND SAFETY INSTRUCTIONS (continued)
A WARNING
The following features are included on your saw to help
reduce the hazard of kickback; however, such features
will not totally eliminate this dangerous reaction. As a
chain saw user, do not rely only on safety devices. You
must follow all safety precautions, instructions, and
maintenance in this manual to help avoid kickback and
other forces which can result in serious injury.

e Chain tension is very important —
— A loose chain will wear the bar and itself.
— A loose chain can jump off bar while you are cut-
ting.
~ A tight chain can break or damage the saw and/or
bar.
The chain stretches during use, especially when
new. Check tension periodically as follows:
— each time the saw is used;
— more frequently when the chain is new;
— as the chain warms up to normal operating temper-
ature.
Chain tension is correct when the chain will move
freely around the bar and chain does not sag beneath
the guide bar.

D. BAR AND CHAIN OIL 1. USE THE FOLLOWING:
® The Guide Bar and Cutting Chain require contin-
uous lubrication 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.
Genuine POULAN/POULAN PRO Bar and Chain
Oil is recommended to protect your unit against
excessive wear from heat and friction. POULAN/
POULAN PRO oil resists high temperature thinning.
If POULAN/POULAN PRO Bar and Chain Oil is not
available. use a good grade SAE 30 oil. Never use
waste oil for bar and chain lubrication.
In freezing weather oil will thicken, making it nec-
essary to thin bar and chain oil with a small
amount 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.
30° or above — 100% lubricant — undiluted.
30°-0°F~ 295% lubricant to 5% #1 Diesel Fuel or
kerosene.
Below 0° F- 90% lubricant to 10% #1 Diesel Fuel
or kerosene.
2. HOW TO FILL THE OIL TANK
a. Stop the engine.
b. Turn the saw on its side with oil cap up. See oil cap
location. Figure 15.
ce. Loosen cap slowly and remove.
d. Fill the oil tank.
e. Replace the oil cap securely.
3. USING THE OILER
Your saw is equipped with an automatic oiler.
e The automatic oiler supplies lubrication to the bar
and chain at all times while the engine is running.
4. IMPORTANT POINTS TO REMEMBER
a. Fill the oil tank each time you refill the fuel tank
to ensure that there will be sufficient oil for the
chain whenever you start and run the saw.
b. The saw will normally use approximately one
tank of bar and chain oil for each tank of fuel
mixture. If less oil is used, check for a plugged oil
hole in the guide bar.
. Keep sawdust and debris cleaned from the oil
holes in the guide bar to allow an adequate oil
flow to the bar and chain.
. Keep spilled and spattered oil wiped from the
unit to avoid sawdust and debris build-up. Pay
particular attention to oil on the fan housing and
starter assembly to avoid overheating the engine.
o
a
e. It is normal for some oil to appear under the
saw after the engine stops. This is excess oil
draining from the bar and chain when the saw is
not in use.

GASOLINE
The two-cycle engine on this product requires a fuel
mixture of regular unleaded gasoline and a high quality
engine oil for lubrication of the bearings and other mov-
ing parts. The correct fuel/oil mixture is 40:1 (see Fuel
Mixture Chart). Too little oil or the incorrect oil type
will cause poor performance and may cause the engine
to overheat and seize.
Gasoline and oil must be premixed in a clean container
approved for gasoline. Always use fresh regular unlead-
ed gasoline.
This engine is certified to operate on unleaded gasoline.
2-CYCLE AIR-COOLED OIL
POULAN PRO 40:1, 2-cycle engine oil is strongly rec-
ommended. POULAN PRO oil is specially blended with
fuel stabilizers and reduced smoke additives.
Fuel stabilizers protect the fuel from oxidation and
the formation of gum and varnish.
Under average conditions, regular unleaded gasoline
stays fresh for only 30 to 60 days out of the refinery.
. POULAN PRO 40:1, 2-cycle engine oil with fuel sta-
bilizers will extend the fuel life up to 5 times.
‚0
If POULAN PRO 40:1, 2-cycle engine oil is not avail-
able, use a good quality 2-cycle engine oil, formulated
for AIR-COOLED engines, that has a recommended
fuel mixture of 40:1.
IMPORTANT! Do not use:
¢ AUTOMOTIVE OIL
® BOAT OILS (NMMA, BIA, etc.)
These oils do not have proper additives for 2-cycle, AIR-
COOLED engines and can cause engine damage.
GASOLINE AND OIL MIXTURE
Mix gasoline and oil as follows:
e Consult Fuel Mixture Chart for correct mixture.
e Do not mix gasoline and oil directly in the fuel tank
of the engine.
FOR ONE GALLON OF FUEL:
e Pour 3.2 ounces of high quality, 2-cycle engine oil
into an empty container approved for gasoline.
® Add one gallon of regular unleaded gasoline to the
container, then securely replace the cap. Shake the
container momentarily to assure oil is thoroughly
mixed. The fuel is ready for use.

without contacting any object.
Grip the front handle with your left hand and place your
right foot through the opening in the rear handle.
Set fast idle by depressing the throttle lock with your
right hand. Then squeeze throttle trigger and hold.
With your thumb, press the fast idle lock down and
hold. Next, release the throttle trigger.
If throttle trigger is squeezed accidentally during
starting it will be necessary to reset the fast idle
lock.
Pull starter rope handle with your right hand until
engine attempts to start. Then push the blue choke
knob in to the half position..Continue pulling the
starter rope handle until the engine starts.
Push choke knob in to the OFF position, then squeeze
and release the throttle trigger to allow engine to idle.
IMPORTANT POINTS TO REMEMBER
e When pulling the starter rope, do not usc the full
extent of the rope as this can cause the rope to break.
Do not let the starter rope snap back -- hold the han-
dle and let the rope rewind slowly.
If the engine floods, let the unit sit for a few minutes,
then repeat starting procedure.
For cold weather starting, allow the engine to warm
up (30-45 sec.) at half-choke position, then move
choke to the “Off” position. Do not cut material with
the choke at the “Full” or “Half” position.

TYPES OF CUTTING
A. BASIC CUTTING TECHNIQUE
1. IMPORTANT POINTS
a. Cut wood only. Do not cut metal; plastics; mason-
ry; non-wood building materials; etc.
b. Stop the saw if the chain strikes a foreign object.
Inspect the saw and repair or replace parts as nec-
essary.
c. Keep the chain out of dirt and sand. Even a
small amount of dirt will quickly dull a chain and
thus increase the possibility of kickback.
A KICKBACK WARNING
Contact at the upper portion of the tip of the guide bar
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
toward the operator. This is kickback. 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 in serious injury.

Figure 19
2. OTHER REACTIVE FORCES
Pinch-Kickback and Pull-In occur when the chain
is suddenly stopped by being pinched, caught, or
by contacting a foreign object in the wood. This
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 chain rotation. Either reaction
can result in loss of control and possible serious injury.
® Pinch-Kickback —
— occurs when the chain on top of the bar is sud-
denly stopped.
— rapidly drives the saw straight back toward the
operator.
e Pull-In —
— occurs when the chain on the bottom of the bar is
suddenly stopped.
— pulls the saw rapidly forward.
>
USING YOUR CHAIN SAW
Practice cutting a few small logs using the following
technique to get the “feel” of using your saw before
you begin a major sawing operation.
a. Accelerate engine to full throttle before entering
cut by squeezing the throttle trigger.
b. Begin cutting with the saw frame against the
log. Figure 19.
c. Keep the engine at full throttle the entire time
you are cutting.
d. Allow the chain to cut for you; exert only light
downward pressure. If you force the cut, damage to
the bar, chain, or engine can result.
. Release the throttle trigger as soon as the cut is
completed, allowing the engine to idle. If you run
the saw at full throttle without a cutting load,
unnecessary wear can occur to the chain, bar, and
engine.
. To avoid losing control when cut is complete, do
not put pressure on saw at end of cut.
g. Stop the engine before setting the saw down.

B. TREE FELLING TECHNIQUES
1. CAREFULLY PLAN YOUR SAWING OPERA-
TION IN ADVANCE
a. Clear the work area. You need a clear area all
around 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 direction and speed.
2.) The LEAN of the tree. The lean of a tree
might not be apparent due to uneven or sloping
terrain. Use a plumb or level to determine the
direction of tree lean.
3.) WEIGHTED and BRANCHES on one side.
4.) 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
fall on you while cutting.
. Make sure there is enough room for the tree to
fall. Maintain a distance of 2 1/2 tree lengths from
the nearest person or other objects. Engine noise
can drown out a warning call.
eo? о
o
—
f. Remove dirt, stones, loose bark, nails, staples,
and wire from the tree where cuts are to be
made.
g. Plan to stand on the up-hill side when on a
slope. Figure 20.
h. Plan to clean retreat path to the rear and diago-
nal to the line of fall. Figure 21.

A WARNING
DO NOT CUT:
— near electrical wires or buildings.
— if you do not know the direction of tree fall.
— at night since you will not be able to see well.
— during bad weather - rain, snow, strong wind, etc.
2. FELLING TREES
The notch method is used to fell trees. A notch is cut
on the side of the tree in the desired 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. Cut into the buttresses
vertically. then horizontally. Figure 20.
a. Make notch cut. then felling cut. Figure 22.
Cut 1 Cut top of the notch first, through 1/3 of the
diameter of the tree.
Cut 2 Complete the notch by making bottom cut.
Remove the notch of wood.
Cut 3 Make felling cut on opposite side of the
notch about 2" higher than bottom of notch.
“ b. Leave enough uncut wood between the felling cut
and the notch to form a hinge. Figure 23.
NOTE: The hinge helps to keep the tree from twist-
ing and falling in the wrong direction.
с. Use a wedge if there is any change that the tree will
not fall in the desired direction.

A WARNING
Stay on the uphill side of the terrain to avoid injury
from the tree rolling or sliding downhill after it is felled.
Figure 21.
NOTE: Before felling cut is complete, use wedges to
open the cut when necessary to control the direction
of fall. Use wood or plastic wedges, but never steel or
iron, to avoid kickback and chain damage.
Figure 23
d. Be alert to signs that the tree is ready to fall:
1.) Cracking sounds.
2.) Widening of the Felling Cut.
3.) Movement in the upper branches.
e. As tree starts to fall, stop saw, and get away quickly
on your planned retreat path.
f. Be extremely cautious with partially fallen trees
that may be poorly supported. When a tree doesn’t
fall completely, set the saw aside and pull down the
tree with a cable winch, block and tackle, or trac-
tor. To avoid injury, do not cut down a partially
fallen tree with your saw.
DON’T PUT YOURSELF IN THESE POSITIONS
Check the wind — Check the lean —
Check the balance —
Don’t cut down wind Don’t cut on lean side Don’t cut on weighted side
— 12 —
C. BUCKING
Bucking is the term used for cutting a fallen tree to
the desired log size.
1. IMPORTANT POINTS
a. Cut only one log at a time.
b. Cut shattered wood very carefully. Sharp pieces
of wood could be flung toward operator.
Use a sawhorse to cut small logs. Never allow
another person to hold the log while cutting and
never hold the log with your leg or foot.
.Do not cut in an area where logs, limbs, and
roots are tangles such as in a blown down area.
Drag the logs into a clear area before cutting by
pulling out exposed and cleared logs first.
. Give special attention to logs under strain to
prevent the saw from pinching. Make the first cut
on the pressure side to relieve the stress on the log.
Figure 24.
Cc.
o
ba
TYPES OF CUTTING USED (Figure 25)
— Overcutting — begin on the top side of the log with
the bottom of the saw against the log: exert light
pressure downward.
— Undercutting — begin on the under side of the log
with the top of the saw against the log; exert light
pressure upward. During undercutting, the saw will
tend to push back at you. Be prepared for this reac-
tion and hold the saw firmly to maintain control.
A WARNING
Never turn the saw upside down to undercut. The saw
cannot be controlled in this position.
A WARNING
If saw becomes pinched or hung in a log, don’t try to
force it out. You can lose control of the saw resulting in
injury and/or damage to the saw. Stop the saw, drive a
wedge of plastic or wood into the cut until the saw can
be removed easily. Figure 26. Restart the saw and care-
fully re-enter the cut. To avoid kickback and chain dam-
age, do not use a metal wedge. Do not attempt to restart

out of the way to avoid tripping over them.
A WARNING
Never climb into a tree to limb or prune. Do not stand
on ladders, platforms, a log, or in any position which
can cause you to lose your balance or control of the saw.
1. LIMBING
a. Always limb a tree after it is cut down. Only then
can limbing be done safely and properly.
b. Leave the larger limbs underneath the felled
tree to support the tree as you work.
c. Start at the base of the felled tree and work
toward top, cutting branches and limbs. Remove
small limbs with one cut. Figure 29.
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 the
bucking section.
1.) Undercut 1/3 of the way through the log.
2.) Finish with an overcut.
f. Always use an overcut to cut small and freely
hanging limbs. Undercutting could cause limbs to
fall and pinch the saw.
Be alert for springback. Watch out for branches that —
;
Keep a clear work area. Frequently clear branches
2. PRUNING
a. Limit pruning to limbs shoulder height or
below. Do not cut if branches are higher than your
shoulder. Get a professional to do the job.
b. Refer to Figure 30 for pruning technique.
Undercut 1/3 of the way through the limb near
the trunk of the tree.
2.) Then make an overcut farther out from the
trunk.
Keep out of the way of the falling limb.
Finish with a cut flush to the trunk of the tree.

GENERAL MAINTENANCE
A good maintenance program of regular inspection and
care will increase the service life and help to maintain
the safety and | performance of your saw.
© Make all adjustments or repairs (except carburetor
adjustment) with:
— spark plug wire disconnected.
— engine cool as opposed to a saw that has just been
run.
® Use only POULAN PRO accessories and replace-
ment parts as recommended.
. GUIDE BAR AND CHAIN
Increase the service life of your Guide Bar and Chain by:
— Using the saw properly and as recommended in this
manual. -
— Maintaining correct chain tension, page 8.
— Proper lubrication, page 9.
— Regular maintenance as described in this section.
1.CHAIN MAINTENANCE
* Have the chain sharpened by a qualified service
dealer when:
— wood chips are small and powdery. Wood chips
made by the saw chain should be about the size of
the teeth of the chain. -
— saw has to be forced through the cut.
— saw cuts to one side.
CAUTION: JAlways wear gloves when handling the
chain. The chain can be sharp enough to cut you even
though it is too dull to cut wood.
2.GUIDE BAR MAINTENANCE
e Check the saw for loose bolts, screws, nuts, and fit-
tings regularly. Loose fasteners can cause an unsafe
condition as well as damage to your saw.
A WARNING
Have all chain saw service performed by a qualified ser-
vice dealer other than the items listed in the mainte-
nance section of this manual.
e 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.
e Replace the guide bar when: ~~
— the inside groove of guide bar rails is worn.
— the guide bar is bent or cracked. See Figure 31.
e Use only the replacement Reduced-Kickback
Guide Bar specified for your saw in the “Specifi-
cation” section.
a. Remove the guide bar to service.
b. Clean the oil holes at least once after every five
hours of operation. ‚
c. Remove sawdust from the guide bar groove peri-
odically with a putty knife or a wire.

2. Remove the muffler cover screws and muffler cover.
Figure 32.
3. Remove the spark arrestor screen. Figure 32.
4.Clean the screen with a wire brush or replace if
breaks are found.
AIR FILTER
® A dirty air filter decreases the life and performance
of the engine and may increase fuel consumption and
harmful emissions.
e Clean the air filter as follows:
— check filter after every 20 hours of operation.
— more frequently in very dusty conditions.
I. Remove the cylinder cover screws and cylinder cover.
Figure 33.
2. Pull out the air filter.
3. Wash the filter in soap and water.
ОМ: Ро not use gasoline or any other flam-
mable liquid to clean the filter; doing so can create
a fire hazard and produce harmful evaporative
emissions.

D. CHAIN BRAKE
I. Keep the clutch drum and brake band clean and
free of sawdust. tree sap, and dirt so the brake will
stop the chain in the shortest possible time.
2. Clean the entire mechanism thoroughly every 10
tanks of fuel or every 5 hours of operation, whichever
is less. Do not allow oil or grease to get on the band
or drum. Figure 34.
3. Inspect the assembly for worn or damaged parts
after every time the unit is cleaned. The entire unit
must be replaced when any part is broken, bent, or
damaged in any other way. If any portion of the brake
band is less than 1/32" thick, the entire chain brake
must be replaced.
4. Check to see if the brake works properly after any
maintenance. If the chain does not appear to stop
instantly, the chain brake needs replacement. Any time
the chain brake operation has noticeably changed it
has exceeded its service life and must be replaced.

Figure 34
A WARNING
The effectiveness of a chain brake in reducing injuries
has not been fully determined. Poulan/Poulan Pro cannot
represent that a chain brake is an effective safety device
to prevent or reduce the hazard of injuries resulting from
kickback. Do not assume that the chain brake will pro-
tect you in the event of kickback. Instead, use the saw
properly and carefully to avoid kickback. Proper opera-
tion is outlined in the Operator's Manual. Repairs on the
chain brake must be made by qualified service personnel.
Take you saw/chain to the place of purchase if purchased
from a servicing dealer, or to the nearest Poulan/Poulan
Pro Authorized Master Service Dealer.
E. SPARK PLUG -- Replace the spark plug yearly.

F. CARBURETOR ADJUSTMENTS
Carburetor adjustment is critical and if done improperly can permanently damage the engine as well as the carbure-
tor. Please read all instructions and consult the Troubleshooting section of this manual before beginning this process.
If the engine does not operate according to these instructions after repeating the adjusting steps, do not use the unit.
For further assistance, contact your Authorized Service Dealer.
The carburetor has been adjusted at the factory for sea
level conditions. Adjustments may become necessary if
the saw is used at significantly higher altitudes or if you
notice any of the following conditions:
® Chain moves when the engine runs at idle speed. See
“Idle Speed Adjustment.”
Saw will not idle. See “Idle Speed Adjustment” and
“Low Speed Mixture Adjustment.”
Engine dies or hesitates when it should accelerate.
See “Acceleration Adjustment.”
Loss of cutting power which is not corrected by air
filter cleaning. See “High Speed Mixture Adjust-
ment.”
A WARNING
The chain will be moving during most of this procedure.
Wear your protective equipment and observe all safety
precautions.
A WARNING |
In “Low Speed Mixture Adjustment,” recheck idle
speed after each adjustment. The chain must not move
at idle speed. `
CARBURETOR PRESETS (Figure 35)
If your engine will not start due to suspected improper
carburetor adjustment, the following presets may be
required. If used, it is recommended that all steps within
the adjustment procedure be completed in order to
assure a properly set carburetor. If presets are not need-
ed, proceed to section “Idle Speed Adjustment.”
When making adjustments be careful not to force the
plastic limiter caps beyond the stops or damage will
occur.
Very small adjustments can affect engine performance. It
is important to turn the screw a very small amount per
adjustment and test performance before making further
adjustments. Each adjustment should be no more than
the width of the slot in the adjusting screw.
Turn both of the mixture screws counterclockwise
until they stop.
Turn idle speed screw clockwise until it stops. Now
turn counterclockwise 4 1/2 turns.
If engine fails to start after performing carburetor pre-
sets, the unit may be flooded. .
Start the engine and operate for three (3) minutes to
warm up. Go to “Adjusting Procedure.”

ADJUSTING PROCEDURE
Idle speed adjustment
e Allow the warm engine to idle.
e Adjust the idle speed screw until the engine contin-
ues to run without stalling and without the chain
moving.
— Turn screw clockwise to increase engine speed if
engine stalls or dies.
— Tum screw counterclockwise to slow engine down
and/or to keep the chain from turning.
® No further adjustments are necessary if the chain
does not move at idle speed and if performance is
satisfactory.
Low speed mixture adjustment
e Allow engine to idle.
® Тит the low speed mixture screw slowly clockwise
until the RPM starts to drop. Note the position.
© Turn the low speed mixture screw counterclockwise
until the RPM speeds up and starts to drop again.
Note the position.
e Set the low speed mixture screw at the midpoint
between the two positions.
High speed mixture adjustment
IMPORTANT: Do not operate engine at full throttle for
prolonged periods while making high speed adjustments
as damage to the engine can occur.
e Make a test cut.
e Based on performance of the saw while cutting,
adjust the high speed mixture screw in 1/16 turn
increments as follows:
— Clockwise if saw smokes or loses power in the cut.
Do not adjust for best power by sound or speed,
but judge by how well the saw performs in the cut.
— Counterclockwise if the saw has speed while out
of the cut, but dies in the cut or lacks power while
cutting.
e Repeat the test cut.
e Continue with 1/16 tum adjustments until the saw
performance is acceptable while cutting.
e After completing adjustments, check for acceleration.
Acceleration check
e If the engine dies or hesitates instead of accelerating,
turn the low speed mixture screw 1/16 of a turn at a
time counterclockwise until you have smooth accel-
eration.
® Check the idle speed for stability and no chain
movement. Adjust as necessary.
e Recheck for smooth acceleration and stable idle.
Repeat process as necessary for acceptable perfor-
mance.
[CAUTION:]A carburetor setting that is too lean
(clockwise adjustment on high speed screw for maxi-
mum speed) will cause engine damage to any 2-cycle
engine from overheating and lack of lubrication. Never
set the high speed screw so far clockwise that you have
high engine speed lacking power to cut. An effective
approach follows.
— Tum high speed screw counterclockwise until engine
loses power while cutting.
— Turn high speed screw clockwise using 1/16 turn
increments only until the engine has power while cut-
ting.

G. STORAGE
Immediately prepare your unit for storage at the end of
the season or if it will not be used for 30 days or more.
Allow the engine to cool, and secure the unit before stor-
ing or transporting it in a vehicle. Store unit and fuel in
an area where fuel vapors cannot reach sparks or open
flames from water heaters, electric motors or switches,
furnaces, etc. Store unit with all guards in place.
Position so that any sharp object such as the chain can-
not accidentally cause injury to passers by. Store the
unit out of the reach of children.
A WARNING
GAS CHAIN SAW STORAGE INSTRUCTIONS
If your chain saw is to be stored for a period of time,
clean it thoroughly prior to storage. Remove any dirt,
sawdust. leaves, oil, grease, etc. Store in a clean dry
area.
Clean the entire unit.
Clean air filter. Refer to “General Maintenance”
Inspect the bar clamp area and clean any dirt, saw-
dust, grass, or debris that has collected. Inspect the
guide bar and chain; replace a guide bar that is bent,
warped, cracked, broken, or damaged in any other-
way. Replace a damaged or worn chain.
Lightly oil external metal surfaces to prevent rust
from forming.
x
CAUTION: |Wear gloves when handling the chain.
The chain is sharp and can cut you even when it is not
moving.
Apply a coating of oil to the entire surface of the
guide bar and chain: wrap it in heavy paper or cloth.
Be sure all handles and guards are in place and are
securely fastened. Replace any damaged parts.
ENGINE
Never use engine or carburetor cleaner products in the
fuel tank or permanent damage may occur to fuel system
components.
Follow these instructions:
—
=
[95
- Drain the fuel from the unit into an approved fuel
container.
Drain the fuel lines and carburetor by starting the
engine and letting it run until it stops.
- Allow the engine to cool before storage.
—18_
IMPORTANT: It is important to prevent gum deposits
from forming in essential fuel system parts such as the
carburetor, fuel filter, fuel line, or tank during storage.
Also, experience indicates that alcohol blended fuels
called gasohol (or using ethanol or methanol) can attract
moisture, which leads to oil/gas separation and forma-
tion of acids during storage which will damage your
engine. To avoid engine problems, the fuel system
should be emptied before storage of 30 days or longer.
Fuel stabilizer is an acceptable alternative in minimizing
the formation of fuel gum deposits during storage. Add
stabilizer to the gasoline in the fuel tank or fuel storage
container. Run engine at least 5 minutes after adding sta-
bilizer to allow stabilizer to reach the carburetor.
Poulan Pro 40:1 2-cycle engine oil is specially blended
with fuel stabilizers.
Remove spark plug and pour 1 teaspoon of 40:1 oil
mix through the spark plug opening. Slowly pull the
starter rope 8 to 10 times to distribute oil to inner
engine surfaces.
Replace spark plug with a new one of the recom-
mended type and heat range.
Clean air filter. Refer to “General Maintenance.”
Reinstall all covers and hardware removed for access;
tighten all screws and fasteners.
Check entire unit for loose screws, nuts, and bolts.
Replace any damaged, broken, or worn parts.
Use fresh fuel having the proper gasoline to oil ratio
at the beginning of the next season.
OTHER
Do not store gasoline from one season to another.
Replace your gasoline can if your can starts to rust.
Rust and/or dirt in your fuel system will cause prob-
lems.
Store your unit in a well ventilated area and covered,
if possible, to prevent dust and dirt accumulation. Do
not cover with plastic. Plastic cannot breathe and will
induce condensation and eventual rust or corrosion.
IMPORTANT: Never cover unit while engine and
exhaust areas are still warm.
