SAFETY RULES
WARNING: Always disconnect spark
plug wire and place wire where it cannot
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 safe-
ty rules, precautions, and operating in-
structions 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.

snug-fitting clothing; heavy-duty, non-slip
gloves; eye protection such as non-fog-
ging, vented goggles or face screen; an
approved safety hard hat; and sound bar-
riers (ear plugs or mufflers) to protect your
hearing. Regular users should have hear-
ing checked regularly as chain saw noise
can damage hearing. Secure hair above
shoulder 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 condi-
tion that might be aggravated by strenu-
ous work, check with your doctor before
operating a chain saw.
SCarefully plan your sawing operation in
advance. Do not start cutting until you
have a clear work area, secure footing,
and, if you are felling trees, a planned re-
treat path.
OPERATE YOUR SAW SAFELY
SDo not operate a chain saw with one
hand. Serious injury to the operator, help-
ers, bystanders or any combination of
these persons may result from one-
handed operation. A chain saw is in-
tended 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, unless you are specifically trained to
do so.
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.
SBe alert for springback when cutting a
limb that is under tension so you will not
be struck by the limb or saw when the ten-
sion in the wood fibers is released.
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 im-
proper tools are used to remove or hold
the flywheel when servicing the clutch,
structural damage to the flywheel can oc-
cur and cause the flywheel to burst.
SMake certain the saw chain stops moving
when the throttle trigger is released. For
correction, refer to “Carburetor Adjust-
ments.”
SNever modify your saw in any way. Use
only attachments supplied or specifically
recommended by the manufacturer.
SKeep the handles dry, clean, and free of
oil or fuel mixture.
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.
SKeep fuel and oil caps, screws, and fas-
teners securely tightened.
SUse only Poulan or Poulan Pro accesso-
ries and replacement parts as recom-
mended.
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 engine to cool before refueling.
SMix and pour fuel in an outdoor area on
bare ground; store fuel in a cool, dry, well

3
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: Kickback can occur when
the moving chain contacts an object at the
upper portion of the tip of the guide bar or
when the wood closes in and pinches the
saw chain in the cut. 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 light-
ning fast, reverse reaction which kicks the
guide bar up and back toward the operator.
If the saw chain is pinched along the top of
the guide bar, the guide bar can be driven
rapidly back toward the operator. Either of
these reactions can cause loss of saw con-
trol which can result in serious injury.Guard
against kickback
Rotational Kickback is the rapid upward
and backward motion of the chain saw that
can occur when the moving saw chain near
the upper portion of the tip of the guide bar
contacts an object such as a log or a
branch.
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 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. Pinch-Kickback drives the
saw straight back toward the operator. Pull-
In pulls the saw away from the operator. Ei-
ther reaction can result in loss of control and
serious injury.
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.
A v o i d P u l l --- I n :
SAlways begin cutting with engine at full
speed and saw housing against wood.
SUse wedges made of plastic or wood.
Neverusemetaltoholdthecutopen.
Kickback Path
Clear the work area; avoid obstructions.
REDUCETHECHANCEOF
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
object 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 through a
particular log or branch.
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
tension at regular intervals with the en-
gine stopped, never with engine running.
Make sure the bar clamp nuts are secure-
ly tightened after tensioning the chain.
SBegin and continue cutting at full speed. If
chain is moving at a slower speed, there is
greater chance of kickback occurring.
SCutonelogatatime.
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 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 encircling
and your left thumb under the front handle-
bar. Keep your right hand completely
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 han-
dlebar so it is in a straight line with your
right hand on the rear handle when mak-
ing bucking cuts. Never reverse right and
left hand positions for any type of cutting.
Never reverse
hand positions
Stand to the left of
the saw
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 saw.
SDo not cut above shoulder height. It is dif-
ficult 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 dangerous reac-
tion. 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.
SReduced-Kickback Guide Bar, designed
with a small radius tip which reduces the
size of the kickback danger zone on 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.

NOTE:If this saw is to be used for com-
mercial logging, you must order and
install a chain brake to comply with Feder-
al OSHA Regulations for Commercial Log-
ging. Contact your Authorized Service
Dealer or call 1-800-554-6723.
SAFETY NOTICE: Exposure to
vibrations through prolonged use of
gasoline powered hand tools could cause
blood vessel or nerve damage in the
fingers, hands, and joints of people prone
to circulation disorders or abnormal
swellings. Prolonged use in cold weather
has been linked to blood vessel damage in
otherwise healthy people. If symptoms
occur such as numbness, pain, loss of
strength, change in skin color or texture, or
loss of feeling in the fingers, hands, or joints,
discontinue the use of this tool and seek
medical attention. An anti-vibration system
does not guarantee the avoidance of these
problems. Users who operate power tools
on a continual and regular basis must
monitor closely their physical condition and
the condition of this tool.
SPECIAL NOTICE: Your saw is
equipped with a temperature limiting
muffler and spark arresting screen which
meets the requirements of California Codes
4442 and 4443. All U.S. forest land and the
states of California, Idaho, Maine,
Minnesota, New Jersey, Oregon, and
Washington require many internal
combustion engines to be equipped with a
spark arrestor screen by law. If you operate
a chain saw in a state or locale where such

5
regulations exist, you are legally
responsible for maintaining the operating
condition of these parts. Failure to do so is
a violation of the law. Refer to the SERVICE
section for maintenance of the Spark
Arrestor.
Failure to follow all Safety Rules and Precau-
tions can result in serious injury. If situations
occur which are not covered in this manual,
use care and good judgement. If you need
assistance, contact your Authorized Service
Dealer.
ASSEMBLY
The assembly tool provided with your saw
is the only tool needed for assembly. Pro-
tective gloves (not provided) should be
worn during assembly.
ATTACHING THE BAR & CHAIN
(If not already attached)
WARNING: Recheck each assembly
step if the saw is received assembled. Al-
ways wear gloves when handling the chain.
The chain is sharp and can cut you even
when it is not moving!
SLoosen and remove the clamp nuts and
the bar clamp from the saw.
SRemove the plastic shipping spacer (if
present).

SAn adjusting pin and screw is used to ad-
just the tension of the chain. It is very im-
portant when assembling the bar, that the
pin located on the adjusting screw aligns
into a hole in the bar.
Adjustment
Screw
STurn the adjusting screw counterclock-
wise to move the adjusting pin almost as
far as it will go to the rear. This should al-
low the pin to be near the correct position.
Further adjustment may be necessary as
you mount the bar.
SMount the bar as illustrated.
SSlide the bar toward the rear of the saw as
far as possible.
SPrepare the chain by checking the proper
direction. Without following the illustration
it is easy to place the chain on the saw the
wrong direction. Use the illustration of the
chain to determine the proper direction.
Proper chain direction
Tip of Bar
SPlace the chain onto the sprocket located
behind the clutch drum. Fit the chain be-
tween the teeth in the sprocket.
SStart at the top of the bar and fit chain into
groove around the guide bar.
SAfter chain is installed, pull bar forward
until chain is snug in the groove of the bar.
SHold guide bar against the saw frame
making sure the adjusting pin is aligned
with the hole in the bar. Remember this
pin moves the bar forward and backward
as screw is turned. Install the bar clamp.
SReplace the bar clamp nuts and tighten
finger tight. Once the chain is tensioned
you will need to tighten bar clamp nuts.
CHAIN TENSION (Including units with
chain already installed)
NOTE:When adjusting chain tension,
make sure the bar nuts are finger tight only.
Attempting to tension the chain when the
bar nuts are tight can cause damage.
Checking the tension:
Use the screwdriver end of the combination
screwdriver/wrench tool to move the chain
around the bar. If the chain does not rotate, it
is too tight. If too loose, the chain will sag be-
low the bar.

6
Adjusting the tension:
Chain tension is very important. Chain
stretches during use. This is especially true
during the first few times you use your saw.
Always check chain tension each time you
use and refuel your saw.
You can adjust chain tension by loosening
the bar clamp nuts and turning adjusting
screw 1/4 of a turn while lifting up on the bar.
SIf chain is too tight, turn adjusting screw
1/4 turn counterclockwise.
SIf chain is too loose, turn adjusting screw
1/4 turn clockwise.
SLift up the tip of the bar and tighten the bar
clamp nuts with the assembly tool.
SRecheck chain tension. Tension is correct
when chain does not sag below the bar
but still can be moved around the bar.

FUELING & LUBRICATION
FUELING ENGINE
This engine is certified to operate on
unleaded gasoline. Before operation,
gasoline must be mixed with a good quality
2-cycle air-cooled engine oil. We
recommend Poulan/W eed Eater brand oil. If
you do not use this oil, use a good quality
2-cycle air-cooled oil designed to be mixed at
a ratio of 40:1 (A 40:1 ratio is obtained by
mixing 3.2 onces of oil with 1 gallon of
unleaded gasoline). When mixing fuel follow
the instructions printed on the container.
Always read and follow the safety rules
relating to fuel before fueling your unit.
BAR AND CHAIN LUBRICATION
The bar and chain require continuous lu-
brication. Lubrication is provided by the au-
tomatic 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 lu-
brication.
SAlways stop the engine before removing
the oil cap.

STARTING
WARNING: The chain must not move
when the engine runs at idle speed. If the
chain moves at idle speed refer to CARBURE-
TOR ADJUSTMENT within this manual. Avoid
contact with the muffler. A hot muffler can
cause serious burns.
To stop the engine move the switch to the
STOP or OFF position.
To star t the engine hold the saw firmly on
the ground as illustrated below. Make sure
the chain is free to turn without contacting
any object.

Difficult starting or flooded engine:
The engine may be flooded with too much
fuel if it has not started after 10 pulls.
Flooded engines can be cleared of excess
fuel by following the warm engine starting
procedure listed above. Insure the ignition
switch is in the ON or START position.
Starting could require pulling the starter
rope handle many times depending on how
badly the unit is flooded. If engine fails to
start refer to the troubleshooting chart or call
your Authorized Service Dealer.
CUTTING METHODS
IMPORTANT POINTS
SCut wood only. Do not cut metal, plastics,
masonry, non-wood building materials, etc.
SStop the saw if the chain strikes a foreign
object. Inspect the saw and repair parts
as necessary.
SKeep the chain out of dirt and sand. Even a
small amount of dirt will quickly dull a chain
and increase the possibility of kickback.
SPractice cutting a few small logs using the
following techniques to get the “feel” of
using your saw before you begin a major
sawing operation.
SSqueeze the throttle trigger and allow the
engine to reach full speed before cutting.
SBegin cutting with the saw frame against
the log.
SKeep the engine at full speed the entire
time you are cutting.
SAllow the chain to cut for you. Exert only
light downward pressure.
SRelease the throttle trigger as soon as the
cut is completed, allowing the engine to
idle. If you run the saw at full throttle with-
out a cutting load, unnecessary wear can
occur.
STo avoid losing control when cut is com-
plete, do not put pressure on saw at end
of cut.
SStop the engine before setting the saw
down.
TREE FELLING TECHNIQUES
WARNING: Do not cut near buildings or
electrical wires if you do not know the direc-
tion of tree fall, at night since you will not be
able to see well, or during bad weather such
as rain, snow, or strong winds. as fall is un-
predictable.
Carefully plan your sawing operation in ad-
vance. You need a clear area all around the
tree so you can have secure footing. Check
for broken or dead branches which can fall
on you causing serious injury.
Natural conditions that can cause a tree to
fall in a particular direction include:
SThe wind direction and speed.
SThe 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 de-
termine the direction of tree lean.
SWeight and branches on one side.
SSurrounding trees and obstacles.
Look for decay and rot. If the trunk is rotted,
it can snap and fall toward the operator.
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. 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.

FELLING LARGE TREES
(6 inches 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
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.
NOTCH CUT AND FELLING THE TREE
SMake notch cut by cutting the top of the
notch first. Cut through 1/3 of the diameter
of the tree. Next complete the notch by
cutting the bottom of the notch. See il-
lustration. Once the notch is cut remove
the notch of wood from the tree.
SAfter removing the cutout of wood, make
the felling cut on the opposite side of the
notch. This is done by making a cut about
two inches 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 falling in the wrong direction.

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.
SBe alert to signs that the tree is ready to
fall: cracking sounds, widening of the fell-
ing cut, or movement in the upper
branches.
SAs tree starts to fall, stop saw, put it down,
and get away quickly on your planned re-
treat path.
SBe 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 tractor.
To avoid injury, do not cut down a partially
fallentreewithyoursaw.
CUTTING A FALLEN TREE
(BUCKING)
Bucking is the term used for cutting a fall-
en tree to the desired log length.
WARNING: Do not stand on the log be-
ing cut. Any portion can roll causing loss of
footing and control. Do not stand downhill
of the log being cut.
Important points
SCut only one log at a time.
SCut shattered wood very carefully; sharp
pieces of wood could be flung toward op-
erator.
SUse 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.
SDo not cut in an area where logs, limbs,
and roots are tangled. Drag the logs into a
clear area before cutting by pulling out ex-
posed and cleared logs first.
TYPES OF CUTTING USED
FOR BUCKING
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. Restart
the saw and carefully reenter the cut. Do not
attempt to restart your saw when it is
pinched or hung in a log.
Overcutting begins on the top side of the
log with the saw against the log. When over-
cutting use light downward pressure.
Overcutting
Undercutting
Undercutting involves cutting on the un-
derside of the log with top of saw against the
log. When undercutting use light upward
pressure. Hold saw firmly and maintain con-
trol. The saw will tend to push back toward
you.
WARNING: Never turn saw upside
down to undercut. The saw cannot be con-
trolled in this position.

SRoll log over; finish with a second overcut.
SGive 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.
BUCKING USING A LOG OR
SUPPORT STAND
SRemember your first cut is always on the
pressure side of the log.
SYour first cut should extend 1/3 of the
diameter of the log.

LIMBING AND PRUNING
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.
IMPORTANT POINTS
SWatch out for springpoles. Use extreme
caution when cutting small size limbs. Slen-
der material may catch saw chain and be
whipped toward you or pull you off balance.
SBe alert for springback. Watch out for
branches that are bent or under pressure.
Avoid being struck by the branch or the
saw when the tension in the wood fibers is
released.
SFrequently clear branches out of the way
to avoid tripping over them.
LIMBING
SAlways limb a tree after it is cut down. Only
then can limbing be done safely and
properly.
SLeave the larger limbs underneath the
felled tree to support the tree as you work.
SStart at base of the felled tree and work to-
ward the top, cutting branches and limbs.
Remove small limbs with one cut.
SKeep the tree between you and the chain
as much as possible.
SRemove larger, supporting branches with
the 1/3,2/3 cutting techniques described
in the bucking section.
SAlways use an overcut to cut small and
freely hanging limbs. Undercutting could
cause limbs to fall and pinch saw.
PRUNING
WARNING: Limit pruning to limbs shoul-
derheightorbelow.Donotcutifbranches
are higher than your shoulder. Get a profes-
sional to do the job.
SMake your first cut 1/3 of the way through
the bottom of the limb.
SNext make a 2nd cut all the way through
the limb. Then cut a third overcut leaving
a 1 to 2 inch collar from the trunk of the
tree.

AIR FILTER
CAUTION: Do not clean filter in gasoline
or other flammable solvent to avoid creating
a fire hazard or producing harmful evapora-
tive emissions.
A dirty air filter decreases engine perform-
ance and increases fuel consumption and
harmful emissions. Always clean after every
5 hours of operation.
Cleaning the air filter:
SClean the cover and the area around it to
keep dirt and sawdust from falling into the
carburetor chamber when the cover is re-
moved.
SRemove the parts as illustrated.
SWash the filter in soap and water.
SReplace parts.
BAR MAINTENANCE
If your saw cuts to one side, has to be forced
through the cut, or been run with an improp-
er amount of bar lubrication it may be nec-
essary to service your bar. A worn bar will
damage your chain and make cutting
difficult.
Replace your bar if bent or the inside rails of
the bar are worn.
SClean the oil holes after each 5 hours of
operation
SRemove sawdust from bar groove period-
ically with a wire or putty knife.

CARBURETOR ADJUSTMENTS
Carburetor adjustment is critical and if done
improperly can permanently damage your
unit. We recommend you contact an Autho-
rized Service Dealer for adjustments.
IDLE SPEED ADJUSTMENT: Turn the Idle
Speed Screw clockwise until it stops. Now
turn the screw counterclockwise 4-1/2
turns. This should allow the engine to run
without the chain turning. If the chain moves
at idle speed, do not use your unit. Contact
an Authorized Service Dealer. Idle speed is
correct when engine runs without stalling
and chain does not turn.
MIXTURE ADJUSTMENTS: If your carbu-
retor includes limiter caps (Plastic caps on
the mixture screws) , do not force the screws
beyond the stops of the limiter caps or dam-
age will occur. Do not remove these caps.
Small adjustments will affect your unit. Do
not adjust more than 1/16th turn without
checking performance.
CHAIN SHARPENING
Chain sharpening is a complicated task that
requires special tools. We recommended
you refer chain sharpening to a professional
chain sharpener
IGNITION TIMING
Ignition timing is fixed and nonadjustable.
SPARK PLUG
Replace the spark plug yearly. Gap to .025”.
STORAGE
WARNING: Stop engine and allow to
cool, and secure the unit before storing or
transporting 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 cannot accidentally
cause injury to passersby. Store the unit out
of reach of children.
SBefore storing, drain all fuel from the unit.
Start engine and allow to run until it stops.
SClean the unit before storing. Pay particu-
lar attention to the air intake area, keeping
it free of debris. Use a mild detergent and
sponge to clean the plastic surfaces.
SDo not store the unit or fuel in a closed
area where fuel vapors can reach sparks
or an open flame from hot water heaters,
electric motors or switches, furnaces, etc.
SStore in a dry area out of reach of children.
CAUTION: It is important to prevent gum
deposits from forming in essential fuel sys-
tem parts such as the carburetor, fuel filter,
fuel hose, or fuel tank during storage. Alco-
hol blended fuels (called gasohol or using
ethanol or methanol) can attract moisture
which leads to fuel mixture separation and
formation of acids during storage. Acidic gas
can damage the engine.
