WARNINGS AND SAFETY INSTRUCTIONS
(See Additional Safety Instructions throug^hout this Manual)
GUARD AGAINST KICKBAGK
^ckback is a dangerous reaction that can lead to serious in
jury. Do not rely only on the safety devices provided with
your saw. As a chain saw user, you must take special safety
recautions to help keep your cutting jobs free from acci-
§
ent or iniuiy.
!^cKback occur when the moving chain con
tacts ^ olnect at the upper portion of the tip of
the goide bar or when the wood closes in and
pincnes 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
lightning fast j reverse reaction which kicks the
lide 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 rapidly dnven back to
ward the operator. Either of these reactions cap
cause loss of saw control which can result in seri
ous injury

A KICKBACK WARNING
....
___________________
REDUCE THE CHANCE OF KICKBACK
1.
Recognize that kickback can happen. With a
basic understanding of kickback, you can reduce the
element of surprise which contributes to accidents.
2.
Never let the moving chain contact any object
at the tip of the guide ban Figure 1.
3.
Keep the working area free from obstructions
such as other trees, brandies, rocks, fences, stumps,
etc. Figure 2, Eliminate or avoid any obstruction
that your saw chain cotdd hit while you áre cutting
throu^ a particular log or branch,
4.
^ep your saw chain sharp and properly ten
sioned. A loose or dull chain can increase the chance
of kickback to occur. Follow manufacturer’s chain
shaipening and maintenance instructions. Check
tension at regular intervals with the engine stopped,
never with the engine running. Make sure the bar
clamp nuts are securely ti^tened after tensioning
the cnain.
Begin and continue cutting at full throttle. If
5,
the chain is moving at a slower speed, there is greater
chance for kickback to occur.
Cut one log at a time.
6.
Use extreme caution when re-entering a pre
7.
vious cut.
8,
Do not attempt plunge cuts.
Watch for shifting logs or other forces that could
9.
close a cut and pinch or fall into chain.
lO^Use the Reduced-Kickback Guide Bar and
Low-Kickback Chain specified for your saw;
MAEVTAIN CONTROL
Keep a good, firm grip on the saw with both

your are right handed or left handed. Keepyourleft
arm straight with the elbow locked.
2. Position your left hand on the front handlebar
so it is in a straight line with your right hand
on the rear handle when making bucking cuts.
Figure 3 . Never reverse right ana left hand posi
tions for any t3pe of cutting.
3. Stand with your weight evenly balanced on
both feet.
4i. Stand slightly to the left ride of the saw to
keep your body from being in a direct line
with the cutting chain. Figure 3 .
5. Do not overreach. You could be drawn or thrown
off balance and lose control of the saw.
6., Do not cut above shoulder height. It is difficult
to maintain control of the saw above shoulder height
^' places the moving chain dangerously close to
yoxu* upper body.

1. Read your operator's manual carefully until
you completely understand and can follow all safety
rules, precautions, and operating instructions before
attempting to operate the unit.
Restrict the use of your saw to adult users who
2.
imderstand and can follow safety rules, precautions,
and operating instructions fouhd in this manu;^.
4. Do not attempt to use your chain saw during
bad weather conditions such as strong wind, rain,
snow, ice, etc., or at night.
5. Carefully plan your sawing operation in ad
vance. Do not start cutting tmtif you have a clear
work area, secure footing, and, if you are fellingtrees,
a planned retreat path.
AVOID REACTIVE FORCES
Pinch-Kickback and Pull-In occur when the chain
is suddenly stopped by beingpinched, caught, or by
contacting a foreign object m the wood. This sudden
stopping of the chain results in a reversal of the (bain force
usea to cut wood and causes the saw to move in the opposite
direction of the chain rotation. Pinch-Kickbaek drives
the saw straight hack toward the operator. Pull-In pulls
the saw away from the operator. Either reaction can result
in loss of control and possibly serious injury.
To avoid Pinch-Kickback;
1. Be extremely aware of situations or obstruc
tions that can cause material to pinch the top of or
otherwise stop the chain.
2. Do not cut more than one log at a time.
3. Do not twist the saw as the bar is withdrawn from
an under-cut when bucking.
To avoid Pull-In;
1. Always begin cutting with the engine at full
throttle and the saw housing against wood.
2. Use wedges made of plastic or wood, (never of
metal) to hold the cut open.
PIANAHEIAD
1. Wear protective gear. Figure 4 v Always use

away limbs, roots, or other objects.
6.
Make sure the chain will not make contact
with any object while starting the engine.
Never tiy to start the saw when the guide bar is in a
cut or kerf
7. Use extreme caution when cutting small size
brush and saplings. Slender matenal can catch
the saw chain and be whipped toward you or pull you
off balance.
8. Be alert for sprin^ack 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 re
leased.
9. 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
1. Have aU chain saw service performed by a qualiHed service dealer with the exception of me
items listed in the maintenance section of this manu
al. For example, if improper tools are used to remove
or hold the flywheel when servicing the clutch, struc
tural damage to the flywheel can occur and cause the
flywheel to burst.
2.
Keep ftiel apd oil caps, screws, and fasteners
securely tightened.
Keep the handles dry, clean, and free of oil or

4.
Make certain the saw chain stops moving
when the throttle trigger is released. For cor
rection, refer to “Carburetor Adjustments.”
5.
Stop the saw if the chain strikes a foreign ob
ject. Check for alignment, binding, breakage, and
mounting of moving parts and any other condition
that may affect the operation of the unit. Check
guards and all other parts to see if each will operate
properly and perform its intended function. Any part
that is damaged should be properly repaired or re
placed by using the instructions in mis manual or by
taking your unit to your Authorized Service Dealer.
6. Disconnect the spark plug before performing
any maintenance except for carburetor ac(just-
ments.
7. Never modi^ your saw in any way. Use only at
tachments supplied or specifically recommend^ by
the manufacturer.
8. Always replace the handguard immediately if
it becomes damaged, broken, or is other wise
removed,
CAIUIY AND STORE YOUR SAW SAFELY
1. Hand carry with the engine stoppe^ the
muffler away from your body, and the ^de bar
and chain to the rear covered preferably with a scab
bard,
2. Before transporting in any vehicle or storing
in any enclosure, allow^oursawto cool complete
ly, cover the bar and chain, and properly secure to
avoid turnover, fuel spillage, or damage.
3. Empty the hiel tank before storing the took
Use up the fuel left in the carburetor bv starting flie
engine and letting the engine run until it stops.
4. Store unit and hiel 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, electric motors or switches, furnaces, etc.
NOTE: Exposure to vibrations through prolonged use
of gasoline powered hand tools could cause blood ves
sel or nerve damage in the fingers, hands, and wrists
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, orvmsts, discon
tinue the use of this tool and seek medical attention.

KNOW YOUR UNIT
A. INTRODUCTION
Your saw has been designed with safety in mind and in
cludes the following safety features as standard equip
ment:
• Reduced-Kickback Guide Bar
• Low-Kickback Chain
• , Handguard
• Spark Arrestor
• Temperature Limiting Muffler
• Anti-vibration System
• Turbo Clean"* Air Filter System
A WARNING
The following features aré included on your saw
to he^ reduce the hazard of kickback; however,
such léatures will not totally eliminate this dan
gerous 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 iiijury.
B. KICKBACK SAFETY FEATURES
• RedUced-Eickback Guide Bar, designed with a
small radius tip which reduces the size of the kickback danrer zone on the bar tip. Figure 5. A Redu
ced-Kickback Guide Bar is one which has been dem
onstrated to significantly reduce the number and se
riousness of kickbacks when tested in accordance
with the safety requirements for gasoline powered
chain saws as set by the American National Stan
dards Institute, Inc., Standard B175.1 -1991.
• Low-Kickback Chain, designed with a contoured
depth gauge and guard link which deflect kickback
force and allow wood to gradually ride into the cut
ter. Figure 5. Low-Kickback Chain is chain which
has met kickback perform2mce requirements of
ANSI B175.1 (Safety Requirements for GasolinePowered Chain Saws) when tested on a rejiresentative sample of chain saws below 3.8 cubic inch dis
placement specified in ANSI B175.1.
• Handguard, designed to reduce the chance of your
left hand contacting the chain ifyourhand slips off
the front handlebar.
• Position of front and rear handlebars, de
signed with distance between handles and “in-line”
with each other. The ^read and “in-line” position
of the hands prorided by this design work together
to give balance and resistance in controlling
ot of the saw back toward the operator
occurs.

1. READ YOUR OPERATOR’S MANUAL
CAREFULIY
Your Operator’s Manual has been developed to help
you prepare your saw fpr use and to understand its
safe operation. It is important that you read your
manual completely to become familiar with the
unit before you begin assembly or attempt opera
tion. Your POULAN PRO dealer is available to
show you how to operate your saw Be sure to ask
for his assistance.
B. ATTACHING THE SPUR (Optional)
The spur is a special piece of equipment de
signed to assist thei cutting operation. When as
sembled to saw, the spur will dig into tree or log and:
• relieve contact pressure adding ease to the
sawing operation.
• allow the saw to be more easily rotated or
pivoted into the cut.
To Install:
1. Remove the bar clamp nuts, bar clamp, and plastic
spacer. Figure 6. Discard plastic spacer.
NOTE; Be sure to remove the plastic spacer on the
bar stud (between bar clamp and crankcase).
2. Remove the isolator bracket screw. Figure?.
3. Remove and discard the spacer under the isolator
bracket. Figure 7.
4. Position the spur over the two holes in the shroud.
Figure 6, Make sure the bottom screw hole tab on
the spur is positioned betw^eh the shroud and the
isolator bracket (where the spacer was removed).
5. Insert the two spur screws and tighten evenly and
securely.

e. ATTACHING THE BAR AND CHAIN
• Your saw is equ^ped with a Reduced-Kick
back Bar and a Low-^ckback Chain.
• Always use the Reduced-Backback Guide
Bar and Low-Kickback Chain specified for
your chain saw model when replacing these
parts. See the “Specifications^ section.
A WARNING
Do not start the engine without the guide bar and
chain completely assembled. Otherwise, the
clutch can come off and serious injury can result.
I CAUnON: I Wear protective gloves when han
dling or operating your saw. The chain is sharp
and can cut you even when it is not moving!
1. Removetheharclampnuts, bar clamp, and ]}}astic
spacer if you have not already done so. Discaard
plastic spacer.
2. Turn the adjusting screw (Fig^ lO) counter
clockwise to move the adjusting pin almost as far as
it will go to the rear.
3. Mount the guide bar imth the slotted end over the
moimting studs. Figi^ 8 . Position the adjusting
pin in the adjusting pin hole. Figure 8.
4. Hold the chain with the cutters facing as shown in
Figure 9 (inset).
5. Place the chain over and behind the clutch drum
and onto the sprocket. Figure 9 . Fit the bottom of
the drive links between the teeth in the sprocket.
6. Slide the ^de bar towaid the rear of the saw as far
as possible.
7. Start at the top of the bar and fit chain drive links
into the groove around the guide bar. Figure 9.
8. Turn the adjusting pin clockwise until the chain is
snug in the guide bar groove. Figure 10.
D. CHAIN TENSION
• Ck>rrect Chaiu Tensipu is very im^rtant—
- A loose chain will wear thè bar and itself
- A loose chain can jtunp off the bar while you are
cutting
- A tight chain can break or damage the saw and/
orbar.
• The chain stretches during use, especi^y
when new. Check tension periodically as follows:
- each time the saw is used;
- more frequently when the chain is nev^
- as the chain warms up to normal operating
temperature.
• Chain tension is correct when the chain:
~ can be lifted about 1/8" from the Guide Bar at a
point near the middle of the bar and
will move freely around the bar.
installing a new chain, allowthe chain to
be lifted 1/4" from the bar. Thereafter, follow the
instructions as indicated.
• Chain tensioning procedure:
I WARNING: i Always wear ^oves when handl-
ihg the chain. The chain is shaxm and can cut
you even when it is not moving!
NOTE; The bar clamp nuts must be no more than
finger tight to tension the chain correctly.
NÓTE; Hold tip of guide bar up through step 4.
1. yft up the tip of the guide bar and turn the adjust
ing screw clockwise until the chain does not sag be
neath the guide bar. Figúrelo.
2. Check the tension by lifting the chain from the
guide bar at the center of the bar. Figure 11.

6. Wipe up all fuel spills before starting the engine.
6. Move at least 10 feet away from the fueling site
before starting the engine.
7. Stop the engine before removing the fuel cap.
Allow the engine to cool before refueling.
8. Empty the fuel tank before storing the tool. Use
up fuel left in the carburetor by starting the en
gine and letting it run until it stops.
9. 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.
B. FUEL MIXTURE
• Your unit is powered by a two-cycle en
gine which requires a fuel mixture of reg
ular unleaded gasoline and a high quality
engine oil specially made for 2-cycle, air
cooled engines. The intemal design of the
2-<ycle engine requires lubrication of moving
parts. Lubrication is provided when the recom
mended mixture of gasoline and oil is used.
• Genuine POULAN PRO 40:1 engine oil is
strongly recommended for the protection
of your unit. Extensive engineering tests have
proven that POULAN PRO oh resists break
down at operating temperatures common to
2-cycle engines, insulting in dependable per
formance and longer engine life.
• Gasoline must be clean and not over two
months old. Gasoline will chemically break
down and form compounds that cause hard
starting and damage in 2-cycle engines.
• Tbe correct measure of gasoline to oil is
very unportant. Too much oil in the mixture
will foul the spaik plug.
GAUTION! \ Too little oil or incorrect oil will
bause the engine to overheat and seize.
f ^ways mix the fuel thoroughly in a con
tainer since gasoline and oil do not readily
combine. Do not mixgasoUne and oil dir&^ly in
the fuel tank,
C. USE THE FOLLOWING ONLY:
POULAN PRO 40:1 engine oil is strongly recom
mended. Any other POULAN PRO, POULAN,
WEED EATER, or PARAMOUNT brand engine oil
is acceptable if mixed according to the instructions
on the container.
If POULAN PRO, POULAN, WEED EATER, or
PARAMOUNT brand oil is not available, use a good
quality, 2-cycle engine oil mixed at a ratio of 16:1 (8
oz. oil to 1 gal. gasoline).
Does not have proper additives for air-cooled,
2-<ycle engines and can cause engine damage.
• AUTOMOTIVE OIL—
Does not have proper additives for air-cooled,
2-cycle engines and can cause engine damage.
A WARNING
Alcohol blended fuels (called gasohol or using
ethanol or methanol) can attract moisture which
leads to separation and formation of acids dur
ing storage. Acidic gas can damage the fuel sys
tem of an engine while in storage. To avoid en
gine problems, the fuel system should he emp
tied before storage. Drain the gas tank, start the
engine, and let it lom until the fuel lines and car
buretor are empty Use fresh friel after taMng
the unit out of storage* See the “Storage”^ sec
tion for additional information. Never use en
gine or carburetor cleaner products in the fuel
tank or permanent damage may occur.
E. HOWTO MIX FUEL AND FILL TANK
1. Pour the proper measure of en^ne oil into an
approved, marked fuel container. Thqn, fill the
cxintainer with regular unleaded gasoline.
NOTE: If fuel is already in the container, add the
proper measure of engine oil. Then, close the
container tightly and shake it momentarily.
NOTE: Do not mix gasoline and oil directly in the
fuel tank
2i Using a spout or funnel, fill the fuel tank with
fuel mix.
3. Reinstall ihe fuel cap securely.

E BAR AND CHAIN OIL
• The Guide Bar and Cutting Chain require
continuous lubrication to remain in operat
ing condition. Lubrication is provided by theautomatic oiler system when the on 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 discol
oration of the guide bar rails.
• GenuinePOULANorPOULANPROBarand
Chmn Oil is recommended to protect your
unit against excessive wear froin heat and
friction. POULAN or POVLAN PRO oU resists
high temperature thinning. If POULAN or
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.
e ^ freezing weather oil will thicken, making
it necessary 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 lubrica
tion,
6. USE THE FOLLOWING:
30® or above —100% lubricant — undiluted.
30 °-0 ®F — 95% lubricant to 5% #1 Diesel Fuel or
IcGlTOSOHO
Below 0 ®F—90% lubricant to 10% #1 Diesel Fuel
or kerosene.
;—To decrease the oil flow, turn the oil adjust-
i)^ smew clocliwise.
• K the oiler is adjusted to decrease the oil
flow, be sure to readjust the oiler before returning
• When the saw is run at high speed for long
periods of time during certian types of cut
ting, such as pruning and debrancmng:, more oil
canoe delivered than is required. To avoid running
out of chain oil before running out of fuel, check the
oil tank periodically.
9. IMPORTANT POINTS TO
REMEMBER
Fill the oil tank each time you refill the
a.
fuel tanük to ensure that there ^1 be sufflcient
oil for the chain vdienever you start and run the
saw.
Keep sawdust and debris cleaned from
b.
the oil holes in the miide bar to allow an ad
equate oil flow to the bar and chain.
c. ]Efeep spilled and spattered oil wiped from
the unit to avoid sawdust and debris
build-up* P^y particular attention to oil on the
fan housmg and starter assembly to avoid over
heating the engine.
d. It is normal for a small amount of oil to
appear under the saw after the engine
stops. This is excess oil draining from the bar
ana chain when the saw is not in use.
7. HOW TO FILL THE OIL TANK
a.
Stop the engine.
b.
Turn saw on its side with oil cap up. Figure 12.
Loosen cap slowly and wait for pressure in the

1. >^Checkoverthe safety rules and precautions
in this manual. Make certain you completely un
derstand and can apply each one.
2. Check protective gear. Always use eye, hearing,
and head protection devices; safety footwear; protec
tive gloves; and snug fitting clothing.
3.
Check the saw for loose bolts, nuts, or fit*
tin^. Tighten, repair, or r^lace paits as necess^.
Tools required are listed in '^Getting Ready” section.
4.
Check the air filter. Clean the filter before
starting the engme. For location, see the “Air Filter”
section.
3. CONTROL DEVICES
Understanding the control devices on your saw
is an important part of learning how to properly
and safely operate the unit.

5. P^Check the saw chain. The chain should be sharp
and at the correct tension.
6. Check the fuel tank and oil tank. Both tanks
should be filled.
7. P^Check the handles. Handles should be <hy and
free of fuel mixture and oil.
8. P-^Check weather conditions. Do not use your
saw at night or during bad conditions such as strong
wind, rain, snow; etc.
9. P^Check the work area. Keep children, bystand
ers, and animals a safe distance away from tne work
area when starting or operating the saw—a mini
mum of 30 feet.
1. The Start/Stop Switch is moved forward for the
“Start” position and rearward for the “Stop” posi
tion.
2. The two-position Choke helps to start the saw by
controlling the air flow the the fuel system.
3. The Trigger accelerates and controls the speed of
the engine and is designed to be used with the
throttle lock-out.
4. The Throttle tiocfc-out prevents the trigger from
becoming accidentally engaged. The throttle lock
out must be pressed before the trigger can be acti
vated.
5. The Throttle Lock holds the throttle lock-out and
trigger in position while the engine is being started.
Release the throttle lock after the engine is started
by lightly squeezing the trigger.

TYPES OF CUTTING
3. IMPOIOVUilT POINTS TO №MEMBER
a. When pulling the starter rope, do not use the
full ^ent of the rope as this can cause the rope to
break. Do not let the starter rope snap back—
hold the handle and let the rope rewind slowly.
b. If the engine floods, let the unit sit for a few
minutes, then repeat starting procedure using the
half-choke position.
c. For cold weather starting, allow the engine to
warm up (1-2 min.) at the half-^hoke position,
then move choke to the“Off” position. Do not cut
material with choke at “Full” or “Half” position.
■K'
A. BASIC CUTTING TECHNIQUE
1. IMPORTANT POINTS
a.
Cut wood only. Do not cut metal* plastics; ma
sonry; non-wood building materials; etc.
b.
Stop the saw if the chain strikes a foreign
object. Inspect the saw ^d repair or replace
p^s as necessary.
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 WARNING
Kickback can occur when the moving chain con
tacts an object at the upper portion of the tip of the
guide bar or when the wood closes in and pinches
the saw chsw in the cut. Cont<ict at the upper nor- tion of the tip of the guide bar can cause the chai
to dig into the object and stop the chain for an in
stant. The result is a lightning fast, reverse reac
tion which kicks the guide bar up and back toward
the operaton If the saw chain is pinched along the
tpp of the guide bar, the guide oar can be drivjen
rapidly back toward ike operaton Either of these
reactions can cause loss of saw control which can
result in serious injury,________________________

spur égainst the log.
Figure 16
_
2. UNDERSTANDm 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 re
versal of the chain force used to cut wood and causes
the sawto move in the opposite direction of chain ro
tation. Either reaction can result in loss of control
and possible serious injuiy.
• Pinch-Kickback—
occurs when the chain on top of the bar is sudden
ly stopped.
— rapidly drives saw straight back toward operator
• PuU-In~
— occurs Tiriien the chain on the bottom of the bar is
suddenly stopped.
— pulls the saw rapidly forward.
3. PROCEDURE
Practice cutting a few small logs using the following
technique to get the “feel” of using your saw before
you begin a m^'or 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 lo^ Figure 16.
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, dam^
to the bar, chain, or engine can result.
e. Release the throttle trigger as soon as the
cut is completed, allowing the engine to idle. K
you run tiie saw at full throttle without a cutting
load, imnecessaiy wear can occur to the chain,
bar, and engine.
f 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 af
ter cutting.
ST^EFELLI^
1. CAREFULLY PLAN YOUR SAWING OPERA-
TtONINAD
a. Clear the work area. You need a clear area all
at all times.
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
-12-
might not be apparent due to uneven or slop-
ing tenain. Use a plumb or level to determine
the direction of tree lean.
3. ) WEIGHTED and BRANCHES on one side.
4. ) Surrounding TREES and OBSTACLES.
c.
Look for decay and rot. If the tnink is rotted, it
can snap and fail toward the operator.
d.
Check for broken or dead branches which
can fall on you while cutting.
Make sure there is enough room for the
e.
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.
Page 13
£ Remove dirt, stones, loose bark, ii^^, sta
ples, and wire from the tree where cuts are
to be made.
g^. Plan to stand on the up-hill side when cut
ting on a slope. Figure 17.
h. Plan a clear retreat path to the rear and di
agonal to the line of fall. Figure IS.
2.
FEtONG SMALL TREES--LESS THAN
6” IN DIAMETER
If you know the direction of fall:
a.
1. ) Make a single felling cut on the side away from
the direction of fall.
2. ) Cut all the way through,
3. ) Stop the saw, put it down, and get away quickly
h.
DO NOTCIJK A WARNING
—near electrical wires or buildings.
--if you do not know the direction of tree fall.
--St night since you will not be able to see well.
—during bad weather — rain, snow, strong
wind, etc.
3. FELLING LARGE TREES—6” IN DIAMETER
OR MORE
The notch method is used to fell largje 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
the 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 but
tresses vertically, then horizontally. Figure 19,
a. Make the notch cut. Figure 19 .
b.
c.
NOTE; The hinge helps to keep the tree from twist
ing and falling in the wrong direction,
d. Use a wed№ if there is any chance that the tree
on your planned retreat path.
If you are not sure which way the tree will fall, use
the notch method described for felling large trees.
1. ) Cut the bottom of the notch first, througdi 1/3
of the diameter of the tree.
2. ) Complete the notch by niaking the slant cut.
3. ) Remove the notch of wood.
Make the felling cut on the opposite side of the
notch about 2” higher than the bottom of the
notch.
Leave enough uncut wood between the felling cut
and the notch to form a hinge. Figure 20.
will not fall in the desired direction.
A WARNING
Stay on thè uphill side of the terrain to avoid in
jury from the tree rolling or sliding downhill af
ter it is felled. Figure 18 .
NOTE; Before the felling cut is complete, use wedges
to open the cut when necessary to control the direc
tion of fall. Use wood or plastic wed^s, but never
steel or iron, to avoid kickback and chain damagCr
DON’T PUT YOURSELF IN THESE POSITIONS
e. Be alert to signs that the tree is ready to fall:
1. ) Cracking sounds,
2. ) ^dening of the Felling Cut.
^ 3.) Movement in the upper branches.
f. As tree starts to fall, stop thesaw,piait doiun^ and
vei away quickly on your planned retreat path.
g. Be extremely cautious "mth partially fallen trees
that msy 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
taclde, or tractor. To avoid ixquiy, do not cut down
a partially fallen tree with your saw.

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.
Cut shattered wood veiy carefolly. Sharp
b.
pieces of wood could be flung toward the operator.
c.
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.
d.
Bo not cut in an area where logs, limbs, and
roots are tangled such as in a blown down
area. Bre^ the logs into a clear area before cut
ting by pulling out exposed and cleared logs first.
Make the first buckihg cut 1/3 of the way
e.
through the log and HmsH with a 2/3 cut on
the opposite side. As the log is being cut, it will
tend to bend. The saw can become pinched or
himg in the log if you make the firet cut deeper
than 1/3 of the diameter of the log.
f. 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 21.
2. TYPES OF CUTTING USED {Figure 22):
— Overcutting — begin on the top side of the log
with the bottom of me saw against the log; exert
light pressure downward.
— Undercutting—begin on the imder side of the
log with the top of the saw against the log; exert
li^t pressure upward. During undercutting, the
saw will tend to push back at you. Be prepared for
this reaction and hold the saw firmly to maintain
control.
AWARNING
Never turn the saw upside down to undercut. The
sjftw cannot be contr<med in this position.

A WARNING
If saw becomes pinched or hung in a log, don^t try
to forae it out. You can lose control of the saw re
sulting in i^ury and/or damage to the saw. Stop
thé saw, drive a wedge of plastic or wood into the
cut until the saw canbe removed easily. Figure 23.
Réstart the saw and carefully reenter thè eut. To
avoid kickback and chain damage, do not use a
metal wedge. Do not attem]pt to restart your saw
when it is pinched or hung m a log.

D. LIMBING AND PRUNING
A WARNING
Do not stand on the log being cut* Any {k»rtion
can roll causing loss of footing and controL
Use Common Sense
Maintain Secure Footing
• Work slowly, keeping both hands firmly
gripped on the saw. Maintain secure footing and
balance.
• Watch out for springpoles. Use extreme caution
when cutting small size limbs. Slender material may
catch the saw chain and be whipped toward you or
pull you off balance.
• Be xdert for springback. Watch out for branches
that are bent or under pressure as you are cutting to
avoid being struck by the branch or the saw when the
tension in the wood fibers is released.
• Keep a clear work area. Frequently clear
branches out of the way to avoid tripping over them.
AWARNING
Never climb into a tree to limb dr pnme. Do not
stand on ladders, platforms, a log, or in any posi*
tidn which can cause you to lose your balance or
control of the saw.
1. LIMBING
a. Always limb a tree after it is cut doum. Only
then can limbing be done safely and properly.
b. Leave the larger limbs imderheath the
felled tree to support the tree as you work.
c. Start fd the base ofthe felled tree and work
toward the top, cutting branches and liinbs. Re
move small limbs with one cut- Figure 26.
4- Keep the irpe between you and the chain.
Cut from the side of the tree opposite the brmich
you are cutting.
e. Remove larger, supporting branches with
the 1/3/2/3 cutting techniques described in
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.
h. Refer to Figure 27 for the pruning tech
nique.
1. ) U ndercut 1/3 of the way through the limb near
the trunk of the tree.
2. ) Finish with an overcut farther out from the
trunk,
3. ) Keep out of the way of the falling limb.
4. ) Cut the stump flush near the trunk of the tree.
AWARNING
Be alert for and guard against kickback. Do not
allow the moving chain to contact any other
branebes or objects at the nose of the guide bar
when lithbing or pruning. Allowing such contact
can result in sermus iiqnry.

GENERAL MAINTENANCE
A good maintenance program of regular inspection
and care will increase the service life and help to main
tain the safety and performance of your saw.
• Make all aiiyustments or repairs (except car
buretor a^ustments) with:
— spark plug wire disconnected.
— engine cool as opposed to a saw that has just
been run.
A. GUTOE BARAND CHAIN
Increase the service life of your Guide Bar and
Chain by;
— Using the saw properly and as recommended in this
—- Maintaining correct chain tension, page 8.
— Proper lubrication, page 10.
—• Regular maintenance as described in this section.
1, CHAIN MAINTENANCE
• Sharpen the chain 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.
I CAUTlONi I Always wear gloves when handling the
chain. The chain can be sharp enough to cut you
even though it is too dull to cut wood.
1. ) Stop the engine and discohnect the
sparkplug.
2. ) Adjust the chain for proper tension. Page 8.
3. ) Work at the midpoint of the bar, moving the
chain forward by hand as each cutter is filed.
4. ) Sharpen Cutters.
a.) Position the file holder level at a 10
angle on the top plate of the cutter and
depth ^uge. Figure 28.
h.) Align the 25® file holder marks with the
bar and parallel to the center of the chain.
Figures 29 & 31.
NOTE; If your file holder has a 30 ® markj disre
gard this mark and file at a 25® angle.
c. ) File from inside toward outside of cutter,
straight across on forward stroke in one
direction only. Use 2 or 3 strokes per cuttingedge. FigureSO.
d. ) Keep all cutters the same length. Fig
ure 30 .
e. ) File enough to remove any damage to the
cutting edges (side plate add top plate) of
the cutter. Figure 30.
f. ) File chain to meet specifications shown in
Figure 31.
A WARNING
Maintain the proper hook angle accordingto the
ni^ufacturer*» specMcation for the chain you
using. Too much hook angle will increase the
chj^c^ of kickback which can result in serious
iidury« Figures 31 & 33 .___________________

**lVouble Shooting Chart** before proceed
ing with carburetor adjustments.
• For best results, it is recommended that you
have a qualified service dealer make all car
buretor su^ustments. Your dealer has the train
ing, experience, and tools necessary to properly ad
just you saw to meet our factory performance speci
fications. Ì^isseruicc is reoi cowered èyicammJiy. If
it becomes necessary for you to make carburetor
a^* *ustments yourself, follow the described proce
dures very carefully.
• The cwburetor has been adijusted at the fac
tory for sea level conditions. Adjustments may
become nwessaiy if the saw is used at significantly
higher altitudes or if you notice any of the following
conditions:
NOTE; Be sure to properly prepare the saw as de
scribed in “1. Preparation” (below) before making
any adjustments.
— Chain moves when the engine runs at idle speed.
See **2. Idle Speed Adjustment.”
— Saw will not idle. See “2. Idle Speed Adjust
ment” and “3. Low Speed Mixture Adjust
ment.”
■— Engine dies or hesitates when it should acceler
ate. See “4. Acceleration Adjustment.”
— Loss of cutting power which is not corrected by
air filter cleaning. See “5. High Speed Mixture
Adjustment.”
I CAVTfQNlJ perm^ent damagé will occur to
any 2-cycle engine if incorrect carburetor
aijgustments are made.
• If the unit will not operate properly after
makmg these acljustments, take the saw to a
qualified service dealer.
A WARNING
The chain will be moving during most of this pro
cedure. Wear your protective gear and observe
all safety precautions.
1. PREPARATION
a. Stop the engine.
b. Use a fresh fuel mixture with proper gasoline/oil
ratio,
c. Place the saw on a solid, flat surface and make
sure the chain will not contact any object.
d. Locate the three (3) carburetor adjusting screw
openings to the right of the air filter cover. Fig
ure 41.
e. Start the engine and allow engine to idle three
(3) minutes to wann up. The en^Tie must be at
operating temperature for proper adjustrnents to
oeniade.

2. IDLE SPEED ADJUSTMENT
a. Allow the engine to idle.
b. Adjust the Idle Speed Screw imtil the engine
continues to run without stalling and without
the chain moving.
— Turn screw cUxkwise to increase engine
speed if engine ataUs or dies,
— Turn screw coimterclockwise to slow en^ns
down andfor to keep the chain from turning,
c. No further adjustments are necessary if
the chain does not move at idle speed and
if performance is satisfactory.
A WARNING
In Low Speed Mixture Adjustment,** recheck
idle speed ^ter each adjustment. The chain
must not move at idle speed.
3. LOW SPEED MIXTURE ADJUSTMENT
a. Allow engine to idle.
b. Turn the Low Speed Mixture Screw slowly
clockwise until the RPM starts to drop. Note
the position.
c. Turn the Low Speed Mixture Screw slowly
counterclockwise until the RPM speeds up and
starts to drop again. Note the position.
d. Set the Low Speed Mixture Screw at the mid
point between the two positions.
4. AGCELERATION ADJUSTMENT
If the engine dies or hesitates instead of accelerat
ing, turn the Low Speed Mixture Screw 1/16 of a
turn at a time counterclockwise until you have
smooth acceleration.
5. HIGHSPEED MIXTURE ADJUSTMENT
I
CAUTION; j Adjustments as small as 1/16 of a
turn can afiect engine performance. It is im
portant to turn the screw only 1/16 of a turn
per adjustment and test the performance of
the saw before making further adjustments.
a. Make a test cut.
b. Adjust the High Speed Mixture Screw 1/16 of a
tipn as folloyi^:
-— Clockwise if saw smokes or loses power.
— Counterclockwiseifthesawhas speed out of
the cut but lacks power in the cut.
c. Repeat test cut.
d. Continue 1/16 of a turn adjustments imtil the
saw runs smoothly in cut.

E. AIR FILTER
• A dirty air filter:
— reduces cutting power.
— increases fuel consumption.
• Clean the air filter as follows:
— check filter after eveiy 10 tanks of fuel or 5
hours of operation, whichever is less.
— more frequently in very dusty conditions.
1. Clean off carburetor cover and the area around it.
2. Pull the choke to the full position to prevent dirt
from entering the carburetor.
3. Remove the carburetor cover. Figure 42,
4. Carefully remove the air filter.
5. Remove the single air filter screw and separate the
two halves.
I CAUTfQ£jlJ Do not úse gasoline or other flam
mable liquid to clean the filter to avoid
creating a fire hazard.
6. Wash the filter in soap and water.
7. Brush away all dust and debris from the filter.
8. Allow the filter to diy.
9. Reassemble the filter.
10. Brush away all dpt and debris from the surfaces bn
vdiich the filter is to be placed.
11. Reinstall the filter and carburetor coven

F. CLUTCH AND DRUM/SPROCKET
A WARNING
Do not start the engine without the guide bar,
chain, and bar clamp housing comjmetely as
sembled. The clutch can come ofl without the
guide bar and chain completely assembled, and
serious ipjury can result. The clutch shoes and
drum can separate causing the clutch to violent-
ly fly apart and serious iigury can result.
Take the saw to your Authorized Service
Dealer for full clutch inspection and service
after each 100 hours of operation. Itis remm-
mended that you do not tr^sy to service the clutch or
drum!^rocket yourself unless you are a competent
small engine mechanic and have the proper clutch
Service tools. Proper disassembly and repair of the
clutch is extremely important to the life of the en
gine and the safety of the operator.
Inspect the sprocket regularly for wear. A
worn sprocket will make the chain rim erratically
and will shorten the life of the bar and chain. Fig
ure 43.
G. STORAGE
When your saw is to be stored for over 80 days.
Clutch maintenance is required when:
— the chain continues to turn while the engine
idles after the idle speed screw has been
adjusted to its capacity.
— slippage ocisurs during a cut
— a chattering noise occurs during cutting.
Clean the clutch, drum, sprocket^ and sur
rounding area daily during heavy use of the
saw. Check to see that the clutch drum turns freely
and smoothly.
.^ways have a worn sprocket replaced by
your Authorized Service Dealer whenever a
new chain is installed to gain the full life expec
tancy of the chain.

Engine—Fuel Safety.'’
2. Start engine and allow to run at idle speed until the
engine stops.
NOTE; Running the eni;ine until it stops will re
move most of the fuel from the fuel system,
NOTE; It is important to prevent gum deposits
from formingin essential fuel systems parts such as
the earburetorj fuel filter, fuel nosei or tank during
storage. 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 sys
tem of an engine while in storage.
