Snug Protection

__foeet_ Safety Chap,

• Wear protective gear. Always use

steel-toed safety footwear with non-
slip soles; snug-fitting clothing;

heavy-duty, non-slip gloves; eye pro-
tection such as non-fogging, vented
goggles or face screen; an approved
safety hard hat; and sound barriers

(ear plugs or mufflers) to protect your
hearing. Regular users should have
hearing checked regularly as chain
saw noise can damage hearing.

• Secure hair above shoulder length. Do
not wear loose clothing or jewelry; they

can get caught in moving parts.

• Keep all parts of your body away
from the chain when the engine is
running.

• Keep children, bystanders, and ani-
mals at least 30 feet (10 meters)
away from the work area when start-

ing and using the saw.

• Do 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. If
you have any condition that might be
aggravated by strenuous work, check
with doctor before operating.

• Do not start cutting until you have a
clear work area, secure footing, and

especially if you are felling a tree, a
retreat path.

OPERATEYOUR SAW SAFELY

• Do not operate with one hand. Seri-
ous injury to the operator, helpers, or

bystanders may result from one-
handed operation. A chain saw is in-

tended for two-handed use.

• Operate the chain saw only in a well-
ventilated outdoor area.

• Do not operate saw from a ladder or

in a tree.

• 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.

• Do not put pressure on the saw, es-

pecially at the end of the cut. Doing
so can cause you to lose control
when the cut is completed.

• Stop engine before setting saw down.

• Hand carry saw only when engine is
stopped. Carry with muffler away
from body; guide bar& chain project-

ing behind you; guide bar preferably

covered with a scabbard.

• Do not operate a chain saw that is
damaged, improperly adjusted, or not
completely and securely assembled.
Always replace bar, chain, hand
guard, chain brake, or oher parts im-

mediately if hey become damaged,
broken, or are oherwise removed.

MAINTAIN YOUR SAW IN GOOD

WORKING ORDER

• Have all chain saw service per-
formed by a qualified service dealer
except the items listed in the MAINTE-

NANCE section of this manual.

• Make certain the saw chain stops

moving when the throttle trigger is
released. For correction, refer to

CARBURETOR ADJUSTMENT

• Keep the handles dry, clean, and
free from oil or fuel mixture.

• Keep caps and fasteners securely
tightened.

• Nonconforming replacement compo-

nents or lhe removal of safety devices
may cause damage to the unit and
possible injury to he operator or by-

standers. Use only Craftsman" acces-
sories and replacement parts as rec-
ommended. Never modify your saw.

• Maintain chain saw with care.

• Keep unit sharp and clean for better
and safer performance.

• Follow instructions for lubricating and
changing accessories.

• Check for damaged parts. Before fur-
ther use of the chain saw, a guard or
other part that is damaged should be
carefully checked to determine that it
will operate propedy and perform its
intended function. Check for alignment
of moving parts, binding of moving

parts, breakage of parts, mounting and
any other conditions hat may affect its
operation. A guard or other part that is
damaged should be properly repaired
or replaced by a Sears Sen/ice Center

unless olherwise indicated elsewhere
in the instruction manual.

• When not in use, chain saws should
be stored in a dry, high or locked-up

place out of the reach of children.

• When storing saw, use a scabbard or
carrying case.

HANDLE FUEL WITH CAUTION

• Do not smoke while handling fuel or
while operating the saw.

• Eliminate all sources of sparks or
flame in areas where fuel is mixed or

poured.

• Mix and pour fuel in an outdoor area
and use an approved, marked con-
tainer for all fuel purposes. Wipe up
al! fuel spills before starting saw.

• Move at least 10 feet (3 meters) from
fueling site before starting.

• Turn 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.

• Store the unit and fuel in a cool, dry
well ventilated space where fuel va-

pors cannot reach sparks or open
flames from water heaters, electric

motors or switches, furnaces, etc.

GUARD AGAINST KICKBACK

Follow all safety rules to help avoid

kickback and other forces which can
result in serious injury.

Kickback Path

....... F -

Clear The Working Area

z& _____°__

_WARNING: Avoid kickback which

can result in serious injury. Kickback

is the backward, upward or sudden for-
ward motion of the guide bar occurring
when the saw chain near the upper tip

of the guide bar contacts any object

such as a log or branch, or when the
wood closes in and pinches the saw

chain in the cut. Contacting a foreign

object in the wood can also result in

loss of chain saw control.

• Rotational Kickback can occur
when the moving chain contacts an

object at the upper tip of the guide

bar. This contact can cause the

chain to dig into the object, which
stops the chain for an instant. The

result is a lightning fast, reverse
reaction which kicks the guide bar up

and back toward the operator.

• Pinch-Kickback can occur when the
the wood closes in and pinches the

moving saw chain in the cut along
the top of the guide bar and the saw
chain is suddenly stopped. This sud-
den stopping of the chain results in a

reversal of the chain force used to
cut wood and causes the saw to

move in the opposite direction of the
chain rotation. The saw is driven

straight back toward the operator.

• Pull-In can occur when the moving
chain contacts a foreign object in the

wood in the cut along the bottom of
the guide bar and the saw chain is
suddenly stopped. This sudden stop-

ping pulls the saw forward and away
from the operator and could easily
cause the operator to lose control of

the saw.

REDUCE THE CHANCE OF
KICKBACK

• Recognize that kickback can happen.
With a basic understanding of kick-

back, you can reduce the element of

surprise which contributes to acci-
dents.

• Never let the moving chain contact
any object at the tip of the guide bar.

• Keep 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 cutting.

• When cutting a branch, do not let the
guide bar contact another branch or

other objects around it.

• Keep saw chain sharp and properly
tensioned. A loose or dull chain can

increase the chance of kickback.
Follow manufacturer's chain sharp-

ening and maintenance instructions.
Check tension at regular intervals,

but never with engine running. Make
sure chain brake nuts are securely
tightened.

• Begin and continue cutting at full
speed. If the chain is moving at a

slower speed, there is greater
chance of kickback occurring.

• Use extreme caution when reenter-
ing a cut.

• Do not attempt cuts starting with the
tip of the bar (plunge cuts).

• Watch for shifting logs or other forces
that could close a cut and pinch or

fall into chain.

• Use the specified Reduced-Kickback
Guide Bar and Low-Kickback Chain.

Avoid Pinch-Kickback:

• Be extremely aware of situations or
obstructions that can cause material

to pinch the top of or otherwise stop
the chain.

• Do not cut more than one log at a
time.

• Do not twist saw as bar is withdrawn
from an undercut when bucking.

Avoid Pull-In:

• Always begin cutting with the engine
at full speed and the saw housing
against wood.

• Use wedges made of plastic or
wood. Never use metal to hold the

cut open.

MAINTAIN CONTROL

• A good, firm grip on the saw with both
hands will help you maintain control.

Don't let go. Grip the rear handle with
your right hand whether you are right

or left handed. Wrap the fingers of
your left hand over and around the
front handlebar, and your left thumb

under the front handlebar. 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 han-
dle when making bucking cuts.

KICKBACK SAFETY FEATURES

.'I,

!ll, WARNING: The following features

are included on your saw to help reduce
hazard of kickback; however, such fea-

tures will not totally eliminate this danger.

Do not rely only on safety devices. Fol-
low all safety rules to help avoid kick-

back and o_er forces which can result
in serous injury.

• Front Hand Guard: designed to re-
duce 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.

• Reduced-Kickback Guide Bar: de-
signed with a small radius tip which

reduces the size of the kickback

danger zone on the bar tip. This type

bar has been demonstrated to signif-
icantly reduce the number and seri-

ousness of kickbacks when tested in
accordance with ANSI B175.1.

IIL _____.__

_WAKNIN_: WE DO NOT REP-

RESENT AND YOU SHOULD NOT AS-

SUME THAT THE CHAIN BRAKE WILL

PROTECT YOU IN THE EVENT OF A

KICKBACK. Kickback is a lightning fast
action which throws the bar and rotat-

ing chain back and up toward the op-
erator. Kickback can be caused by aI-

lowing contact of the bar tip in the
danger zone with any hard object.

Kickback can also be caused by
pinching the saw chain along the top
of the guide bar. This action may push
the guide bar rapidly back toward the
operator. Either ofthese events may

cause you to lose control of the saw
which could result in serious injury or

even death. DO NOT RELY UPON ANY
OF THE DEVICES BUILT INTO YOUR
SAW. YOU SHOULD USE THE SAW

PROPERLY AND CAREFULLY TO AVOID
KICKBACK. Reduced-kickback guide

bars and low-kickback saw chains re-
duce the chance and magnitude of

kickback and are recommended. Your
saw has a Iow kickback chain and bar

as original equipment. Repairs on a
chain brake should be made by an au-

thorized Sears Service Center. Take
your unit to the place of purchase or to

your nearest Sears Service Center.

• Tip contact in some cases may cause

a lightning fast reverse REACTION,
kicking guide bar up and back toward
operator.

• Pinching the saw chain along the top

of the guide bar may push the guide
bar rapidly back toward the operator.

• Either of _ese reactions may cause

you to lose control of _e saw which
could result in serious injury. Do not

rely exclusively upon safety devices

fuel handling information in the safety

rules section of this manual before you

begin. If you do not understand the
fuel handling information do not at-

tempt to fuel your unit. Seek help from

someone that does understand the in-
formation or call the customer assis-

tance help line at 1-800-235-5878.

GUIDE BAR AND CHAIN OIL
The bar and chain require lubrication.

The chain oiler provides continuous

lubrication to the chain and guide ba£

Be sure to fill the bar oil tank when you
fill the fuel tank (Capacity = 6.8 fi. oz.).

Lack of oil will quickly ruin the bar and

chain. Too little oil will cause overheat-

ing shown by smoke coming from the

chain and/or discoloration of the bar.

For maximum guide bar and chain life,
we recommend you use Craftsman

chain saw bar oil. If Craftsman bar oil

is not available, you may use a good

grade SAE 30 oil until you are able to

obtain Craftsman brand. The oil output

is automatically metered during opera-
tion. Your saw will use approximately

one tank of bar oil for every tank of fuel

mix. Always till the bar oil tank when

you fill the fuel tank.

FUELING ENGINE

='IL________

*!IJWARNING: Remove fuel cap

slowly when refueling.
This engine is certified to operate on

unleaded gasoline. Before operation,

gasoline must be mixed with a good

quality synthetic 2-cycle air-cooled en-

gine oil. We recommend Craftsman

brand synthetic oil. Mix gasoline and

oil at a ratio of 40:1. A 40:1 ratio is ob-
tained by mixing 3.2 ounces of oil with

1 gallon of unleaded gasoline. In-

cluded with this saw is a 3.2 ounce

container of Craftsman brand synthetic

oil. Pour the entire contents of this

container into 1 gallon of gasoline to

achieve the proper fuel mixture.

DO NOT USE automotive oil or marine

oil. These oils will cause engine dam-

age. When mixing fuel, follow instruc-
tions printed on the oil containen

Once oil is added to the gasoline,
shake container momentarily to assure
that the fuel is thoroughly mixed. Al-
ways read and follow the safety rules
relating to fuel before fueling your unit.
IMPORTANT

Experience indicates that alcohol

blended fuels (called gasohol or using
ethanol or methanol) can attract mois-

ture which leads to separation and
formation of acids during storage. Acidic
gas can damage the fuel system of an
engine while in storage. To avoid engine
problems, the fuel system should be
emptied before storage for 30 days or

longer. Drain the gas tank, start the en-
gine and let it run until the fuel lines and
carburetor are empty. Use fresh fuel

next season. See STORAGE instructions
for additional information.

Never use engine or carburetor clean-
er products in the fuel tank or perma-
nent damage may occur.

See the STORAGE section for addition-
al information.

CHAIN BRAKE

Ensure chain brake is disengaged by
pulling the front hand guard back to-

ward the front handle as far as pos-
sible. The chain brake must be disen-

gaged before cutting with the saw.
_tlI_WARNING: The chain must not

move when the engine runs at idle
speed. If the chain moves at idle
speed, refer to CARBURETOR ADJUST-

MENTwithin this manual. Avoid con-
tact with the muffler. A hot muffler can

cause serious burns.
STOPPING YOUR ENGINE

• Move ON/STOP switch to the STOP

position.

STARTING POSITION

• To start the engine, hold the saw

firmly on the ground as illustrated.
Make sure the chain is free to turn

without contacting any object.

call 1-800-235-5878.

CHAIN BRAKE

z%_____=__

*_IbWARNING: If the brake band is
worn too thin it may break when the

chain brake is triggered. With a broken
brake band, the chain brake will not stop

the chain. The chain brake must be re-
placed if any part is worn to less than

0.020 inch (0.5 mm) thick. Repairs on a
chain brake should be made by your
Sears Service Center. Take your unit to
the place of purchase or to the nearest

Sears Service Center.

• This saw is equipped with a chain

brake. The brake is designed to stop
the chain if kickback occurs.

• The inertia-activated chain brake is

activated if the front hand guard is
pushed forward, either manually (by
hand) or automatically (by sudden

movement).

• If the brake is already activated, it is

disengaged by pulling the front hand
guard back toward the front handle
as far as possibie.

• When cutting with the saw, the chain

brake must be disengaged.

CAUTION: The chain brake must be

checked several times daily. The en-
gine must be running when performing

this procedure. This is the only

instance when the saw should be
placed on the ground with the engine

running.
Place the saw on firm ground. Grip the

rear handle with your right hand and
the front handle with your left hand.
Apply full throttle by fully depressing
the throttle trigger. Activate the chain

brake by turning your left wrist against
the hand guard without releasing your

4;SWARNING: When performing the
following procedure, the engine must

be turned off.

Grip the rear handle with your right

hand and the front handle with your left

hand. Hold the chain saw approxi-

mately 14" (35 cm) above a stump or

other wooden surface. Release your

grip on the front handle and use the
weight of the saw to let the tip of the

guide bar fall forward and contact the

stump. When the tip of the bar hits the

stump, the brake should activate.

OPERATING TIPS

• Check chain tension before first use
and after 1 minute of operation. See

CHAIN TENSION in the MAINTENANCE
section.

• Cut wood only. Do not cut metal,

plastics, masonry, non-wood building
materials, etc.

• Stop the saw if the chain strikes a
foreign object. Inspect the saw and

repair parts as necessary.

• Keep the chain out of dirt and sand.

Even a small amount of dirt will

quickly dull a chain and increase the

possibility of kickback.

• Practice cutting a few small logs using
the following steps. This will help you
get the "feeF of using your saw before

you begin a major sawing operation.

• Squeeze the throttle trigger and a!-
low the engine to reach foil speed
before cutting.

• Begin cutting with the saw frame
against the log.

• Keep the engine at foil speed the
entire time you are cutting.

• Allow the chain to cut for you. Exert
only light downward pressure.

• 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. It is
recommended that the engine
not be operated for longer than

30 seconds at full throttle.

• To avoid losing control when cut is
complete, do not put pressure on
saw at end of cut.

• Stop engine before setting saw down.
TREE FELLING TECHNIQUES

d_!_WARNING: Check for broken or
dead branches which can fall while
cutting causing serious injury. Do not

cut near buildings or electrical wires if
you do not know the direction of tree
fall, nor cut at night since you will not
be able to see well, nor during bad

weather such as rain, snow, or strong
winds, etc. If the tree does make con-
tact with any utility line, the utility com-
pany should be notified immediately.

• Carefully pIan your sawing operation
in advance.

• Clear the work area. You need a
clear area all around the tree so you

can have secure footing.

• The chain saw operator should keep
on the uphill side of the terrain as the
tree is likely to roll or slide downhill

after it is felled.

• Study the natural conditions that can
cause the tree to fall in a particular

direction. These conditions include:

• The wind direction and speed.

• The lean of the tree. The lean of a

tree might not be apparent due to
uneven or sloping terrain. Use a

plumb or level to determine the di-
rection of tree lean.

• Weight and branches on one side.

• Surrounding 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. Engine
noise can drown out a warning call.

• Remove dirt, stones, loose bark,
nails, staples, and wire from the tree

where cuts are to be made.

I'" - _O _ - Direction of Fall

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 fail in

the direction of the notch.

NOTE: If tree has large buttress roots,
remove them before making the notch.

If using saw to remove buttress roots,
keep saw chain from contacting

ground to prevent dulling of the chain.
NOTCH CUT AND FELLING TREE

• Make 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. See

illustration. Once the notch is cut, re-
move the wedge of wood from tree.

First cut Felling cut here

\

Hinge

• After removing the wood from the

notch, make the felling cut on the op-
posite 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 be-
tween the felling cut and the notch to
form a hinge. This hinge will help pre-
vent the tree from falling in the wrong

direction.

Hinge holds tree on

stump and helps
control fall

Opening of

Closing
of notch

NOTE: Before felling cut is complete,
use wedges to open the cut when
necessary to control the direction of

fall. To avoid kickback and chain
damage, use wood or plastic wedges,

but never steel or iron wedges.

• Be alert to signs that the tree is

ready to fall: cracking sounds, widen-
ing of the felling cut, or movement in
the upper branches.

• As tree starts to fall, stop saw, put it

down, and get away quickly on your
planned retreat path.

• DO NOT use your saw to cut down a

partially fallen tree. 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 tractor.

CUTTING A FALLEN TREE
(BUCKING)

Bucking is the term used for cutting a
fallen tree to the desired log size.

_WARNING: Do not stand on the
log being cut. Any portion can roll

causing loss of footing and control. Do
not stand downhill of the log being cut.

IMPORTANT POINTS

• Cut only one log at a time.

• 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 tangled. Drag logs
into a clear area before cutting them
by pulling out exposed and cleared
logs first.

SUCKING TECHNIQUES

_WARNING: Ifsaw 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. Re-

start saw and carefully reenter the cut.

Do not use a metal wedge. Do not at-
tempt to restart your saw when it is
pinched or hung in a log.

11

Use a wed e to remove pinched saw

Turn saw OFF and use a plastic or
wooden wedge to force cut open.

Overcutting begins on the top side of

the log with the bottom of the saw

against the Iog. When overcuttiog use
light downward pressure.

Overcutting Undercutting

• Your first cut should extend 1/3 of the

diameter of the log.

• Finish with your second cut.

Using a log for support

2nuCut \

_% , 1st Cut

1stCut

Undercutting involves cutting on the
underside of the log with top of saw
against the log. When undercutting

use light upward pressure. Hold saw
firmly and maintain control. The saw
will tend to push back toward you.

_II, WARNING: Never turn saw up-

side down to undercut. The saw can-

not be controlled in this position.
Always make your first cut on the

compression side of the log. The com-

pression side of the Iog is where the

pressure of the log's weight is concen-
trated.

First cut on compression side of log

Second cut

BUCKING WITHOUT A SUPPORT

• Overcut through 1/3 of the diameter
of the log.

• Roll the log over and finish with a
second overcut.

• Watch for logs with a compression
side to prevent the saw from pinch-

ing. See illustrations above for cut-

ting logs with a compression side.

BUCKING USING A LOG OR
SUPPORT STAND

• Remember your first cut is always on
the compression side of the log. (Re-

fer to the illustrations below for your
first and second cut).

LIMNING AND PRUNING

_kWARNING: Be alert for and guard
against kickback. Do not allow the mov-

ing chain to contact any other branches
or objects at the nose of the guide bar

when Iimbiog or pruning. Allowing such
contact can result in serious injury.

_kI, WARNING: Never climb into a
tree to limb or prune. Do not stand on

ladders, platforms, a log, or in any po-
sition which can cause you to lose

your balance or control of the saw.
IMPORTANT POINTS

• Watch out for springpoles.
Springpoles are small size limbs
which can whip toward you, or pull
you off balance. Use extreme cau-

tion when cutting small size limbs.

• Be alert for springback from any
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.

• Frequently clear branches out of the
way to avoid tripping over them.

CHECK CHAIN TENSION

_kWARNING: Wear protective

gloves when handling chain. The
chain is sharp and can cut you even

when it is not moving.

Chain tension is very important. Chains
stretch 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.

1. Use the screwdriver end of the
chain adjustment tool (bar tool) to

move chain around guide bar to
ensure kinks do not exist. The

chain should rotate freely.

2. Loosen chain brake nuts until they
are finger tight against the chain

brake.

3. Turn adjusting screw clockwise un-
til chain solidly contacts bottom of

guide bar rail.

4. Using bar tool, roll chain around
guide bar to ensure all links are in

bar groove.

5. Lift up tip of guide bar to check for
sag. Release tip of guide bar, then

turn adjusting screw until sag does
not exist.

6. While lifting tip of guide bar, tighten
chain brake nuts securely with the

bar tool.

7. Use the screwdriver end of the bar
tool to move chain around guide bar.

8. If chain does not rotate, it is too
tight. Slightly loosen chain brake
nuts and loosen chain by turning

the adjusting screw counterclock-
wise. Retighten chain brake nuts.

9. If chain is too loose, it will sag be-
low the guide bar. DO NOT operate

the saw if the chain is loose.

ZIL
_I_WARNING: If the saw is operated

with a loose chain, the chain could

jump offthe guide bar and result in se-

rious injury.
CHECK CHAIN SHARPNESS

A sharp chain makes wood chips. A
dull chain makes a sawdust powder
and cuts slowly. See CHAIN SHARP-

ENING in the SERVICE AND ADJUST-
MENTS section.

CHECK GUIDE BAR
Conditions which require guide bar

maintenance:

• Saw cuts to one side or at an angle.

• Saw has to be forced through the cut.

• Inadequate supply of oil to bar/chain.

14

Check the condition of guide bar each

time chain is sharpened. A worn guide

bar will damage the chain and make
cutting difficult.

After each use, ensure ON/STOP

switch is in the STOP position, then
clean all sawdust from the guide bar

and sprocket hole.

To maintain guide bar:

• Move ON/STOP switch to STOP.

• Loosen and remove chain brake
nuts and chain brake. Remove bar

and chain from saw.

• Clean the oil holes and bar groove

after each 5 hours of operation.

• Burring of guide bar rails is a normal
process of rai! wear. Remove these

burrs with a flat file.

• When rail top is uneven, use a fiat

file to restore square edges and sides.

_j_ File Rail Edges_- _

Worn Groove Correct Groove

Replace guide bar when the groove is

worn, the guide bar is bent or cracked,

or when excess heating or burring of

the rails occurs. If replacement is nec-

essary, use only the guide bar speci-

fied for your saw in the repair parts list

or on the decal located on the chain
saw.

for loose or damaged parts. Clean

the unit and decals using a damp
cloth with a mild detergent.

• Wipe off unit with a clean dry cloth.
CHECK CHAIN BRAKE

• Bee CHAIN BRAKE in the OPERATION
section.

CLEAN AIR FILTER
A dirty air filter decreases the life and

performance of the engine and in-
creases fuel consumption and harmful

emissions. Always clean your air filter
after 15 tanks of fuel or 5 hours of op-

eration, whichever comes first. Clean
more frequently in dusty conditions. A

used air filter can never be completely
cleaned. It is advisable to replace your

air filter with a new one after every 50
hours of operation, or annually, which-

ever comes first. To clean filter:

1. Loosen 3 screws on cylinder cover.

2. Remove cylinder cover.

3. Remove air filter.

4. Clean the air filter using hot soapy

water. Rinse with clean cool water.
Air dry completely before reinstalling.

5. Lightly oil air filter before installing

to improve the efficiency of air filter.

Use 2-cycle engine oil or motor oil

(SAE 30). Squeeze excess oil from
filter.

6. Reinstall air filter.

7. Reinstall cylinder cover and 3

screws. Tighten securely.
