whenever pulling the starter rope. The operator and unit  
must be in a stable position while starting. See  
Starting/Stopping Instructions.  
• Always move at least 10 feet (3 meters) from fueling site  
before starting saw.  
• Before you start the engine, make sure the area around  
the saw is clear. Never try to start the saw when the  
guide bar is engaged in a cut.  
• When re-fueling, turn the engine off and allow the saw to  
cool in a non-combustible area, do not place on dry  
leaves, straw, paper, etc. Slowly remove fuel cap and  
refuel unit.  
• Do not start cutting until you have a clear work area,  
secure footing, and a planned retreat path from the  
falling tree.  
• Always store the unit and fuel in a cool, dry, well-venti-  
lated space where fuel vapors cannot reach sparks or  
open flames from water heaters, electric motors or  
switches, furnaces, etc.  
• Do not operate a chain saw that is damaged, improperly  
adjusted, or not completely and securely assembled. Be  
sure that the saw’s chain stops moving when the throttle  
control trigger is released.  
• All chain saw service, other that the items listed in this  
instruction manual maintenance instructions, should be  
performed by a Sears or other qualified service dealer.  
• Shut off the engine before setting the chain saw down.  
• Use extreme caution when cutting small-sized brush  
and saplings because slender material may catch the  
chain saw and whip towards you or cause you to lose  
control.  
• Use the right tool. Only use this chain saw for its intend-  
ed purpose, to cut wood.  
• Never touch the chain or attempt to service the saw  
while the engine is running. Make sure all moving parts  
have stopped. Allow the chain saw to cool, as the chain  
can be hot.  
• When cutting a limb that is under tension, be alert for  
springback so that you will not be struck when the ten-  
sion in the wood fibers is released.  
• Check the bar and chain at frequent intervals for proper  
adjustment. Make sure the bar and chain are properly  
tightened and sharpened. Visually inspect for damage.  
Repair any damage before restarting or operating the  
chain saw.  
• Do not cut through nails, rods in the tree, railroad ties or  
pallets. Inspect a tree that you are going to cut for for-  
eign objects that could cause injury or damage to your  
chain saw.  
• After striking a foreign object, stop the engine and thor-  
oughly inspect for damage. Repair as necessary.  
KICKBACK may  
WARNING:

• Keep the handles dry, clean and free of the oil/fuel mix-  
ture.  
nose or tip of the guide bar touches an  
object, or when the wood closes in and  
pinches the saw chain in the cut. Tip con-  
tact in some cases may cause a lightning-  
fast reverse reaction, kicking the guide bar  
up and back towards the operator. Pinching  
the saw chain along the top of the guide bar  
may push the guide bar rapidly back toward  
the operator. Either of these reactions may  
cause you to lose control of the saw, which  
could result in serious personal injury. Do  
not rely exclusively upon the safety devices  
built into your saw. As a chain saw user,  
you should take several steps to keep your  
cutting jobs free from accident or injury.  
• We do not recommend using the chain saw in a tree or  
on a ladder.  
MAINTAIN YOUR SAW IN GOOD WORKING ORDER  
• All chain saw service, other than the items listed in this  
instruction manual maintenance instructions, should be  
performed by a Sears or other qualified service dealer.  
• Make sure all fasteners are in place and secure.  
• Unauthorized replacement parts or the removal of safety  
devices may cause damage to the unit and possible  
injury to the operator or bystanders. Use only Craftsman  
accessories and replacement parts as recommended.  
Never modify your saw.  
KICKBACK SAFETY PRECAUTIONS  
• When not in use, saw should be stored in a dry, highly  
secure location away from children.  
• With a basic understanding of kickback, you can reduce  
or eliminate the element of surprise. Sudden surprise  
contributes to accidents. Be alert to the potential for  
kickback at all times.  
• When storing saw use a scabbard or carrying case.  
HANDLE FUEL WITH CAUTION  
• Keep a good firm grip on the saw with both hands, the  
right hand on the rear handle and the left hand on the  
front handle, when the engine is running. Use a firm grip  
with thumbs and fingers encircling the chain saw handles.  
A firm grip will help you reduce kickback and maintain  
control of the saw. Don’t let go.  
• Do not smoke while handling fuel or while operating the  
saw.  
• Always eliminate all sources of sparks or flame in areas  
where fuel is mixed or poured.  
• Always mix and pour fuel in an outdoor area and use an  
approved, marked container for all fuels. Always wipe  
up all fuel spills before starting saw.

OIL AND FUEL INFORMATION  
To Obtain Correct Fuel Mix:  
OIL AND FUEL MIXING INSTRUCTIONS  
Thoroughly mix the proper ratio of 2-cycle engine oil with  
unleaded gasoline in a separate fuel can. Use a 40:1  
fuel/oil ratio. Do not mix them directly in the engine fuel  
tank. See the table below for specific gas and oil mixing  
ratios.  
Old and/or improperly mixed fuel are the main reasons for  
the unit not running properly. Be sure to use fresh (less  
than 60 days old) clean unleaded fuel. Follow the instruc-  
tions carefully for the proper fuel/oil mixture.  
Definition of Blended Fuels  
NOTE: One gallon (3.8 liters) of unleaded gasoline mixed  
with one 3.2 oz. (95 ml.) bottle of  
Today's fuels are often a blend of gasoline and oxy-  
genates such as ethanol, methanol, or MTBE (ether).  
Alcohol-blended fuel absorbs water. As little as 1% water  
in the fuel can make fuel and oil separate and lead to for-  
mation of acids during storage. When using alcohol-  
blended fuel, use fresh fuel.  
2-cycle oil makes a 40:1 fuel/oil ratio.

Using Blended Fuels  
If you choose to use a blended fuel, or its use is unavoid-  
able, follow recommended precautions:

Using Fuel Additives  
The bottle of 2-cycle oil that came with your unit contains  
a fuel additive which will help inhibit corrosion and mini-  
mize the formation of gum deposits. It is recommended  
that you use our 2-cycle oil with this unit.  
Gasoline is extreme-  
ly flammable. Ignited  
Vapors may explode. Always stop the engine  
and allow it to cool before filling the fuel  
tank. Do not smoke while filling the tank.  
Keep sparks and open flames at a distance  
from the area.  
WARNING:  
If unavailable, use a good 2-cycle oil designed for  
air-cooled engines along with a fuel additive, such as  
STA-BIL® Gas Stabilizer or an equivalent. Add 0.8 oz.  
(23 ml.) of fuel additive per gallon of fuel according to the  
instructions on the container. NEVER add fuel additives  
directly to the unit's fuel tank.

in a well-ventilated  
Experience indicates that alcohol blended with fuels  
(called gasohol or using ethanol or methanol) can  
attract moisture which leads to separation and forma-  
tion of acids during storage. Acidic gas can damage  
the fuel system of an engine when 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 engine and let it run until fuel lines and  
carburetor are empty. Use fresh fuel next season.  
Never use engine or carburetor cleaner products in the  
fuel tank or permanent damage can occur. See STOR-  
AGE instructions for additional information.

Section of this manual before you begin. If you do not  
understand the oil and fuel information, do not attempt  
to fuel your unit. For more information contact your  
CHAIN BRAKE  
Be sure the chain brake is disengaged by pulling the  
front hand guard back toward the front handle as far  
as possible. The chain brake must be disengaged  
before cutting with the saw.

GUIDE BAR AND CHAIN OIL  
WARNING: The chain brake must not move when the  
engine runs at idle speed. If the chain brake moves at  
idle speed, refer to CARBURETOR ADJUSTMENT in  
this manual. Avoid contact with the muffler. A hot muf-  
fler can cause serious burns.  
The bar and chain require lubrication. The chain oiler  
provides continuous lubrication to the chain and guide  
bar. Be sure to fill the bar oil tank when you fill the fuel  
tank. (Capacity = 6.8 fl. oz.). Lack of oil will quickly  
ruin the bar and chain. Too little oil will cause over-  
heating with smoke coming from the chain and discol-  
oration 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 the  
Craftsman brand. The oil output is automatically  
metered during operation. Your saw will use approxi-  
mately one tank of bar oil for every tank of fuel mix.  
Always fill the bar oil tank when you fill the fuel tank.  
IMPORTANT POINTS TO REMEMBER  
When pulling the starter rope, do not use the full  
extent of the rope as this can cause the rope to break.  
Do not let starter rope snap back. Hold the handle and  
let the rope rewind slowly. For cold weather starting,  
start the unit at FULL CHOKE; allow the engine to  
warm up before squeezing the throttle trigger.  
DO NOT attempt to cut material with the choke/fast idle  
lever in the FULL CHOKE position.  
FUELING THE ENGINE  
WARNING: Remove fuel cap slowly when refueling.  
This engine is certified to operate on unleaded gaso-  
line. Before operation, gasoline must be mixed with a  
good quality synthetic 2-cycle air-cooled engine oil.  
We recommend Craftsman brand synthetic oil. Mix  
gasoline and oil at a ratio of 40:1. 40:1 ratio is  
obtained by mixing 3.2 ounces of oil with 1 gallon of  
unleaded gasoline. Included with this saw is a 3.2  
ounce container of oil. Pour the entire contents of this  
container into one gallon of gasoline to achieve the  
proper fuel mixture. DO NOT use automotive oil or  
boat oil. These oils will cause engine damage. When  
mixing fuel, follow the instructions printed on the oil  
container. Once oil is added to the gasoline, shake  
container momentarily to assure that the fuel is thor-  
oughly mixed. Always read and follow the safety rules  
relating to fuel before fueling your unit.

Chain Lubrication  
A
Adequate lubrication of the saw chain is essential at all  
times to minimize friction with the guide bar. Never starve  
the bar and chain of oil. Running the saw with too little oil  
will decrease cutting efficiency, shorten saw chain life,  
cause rapid dulling of chain, and cause excessive wear of  
bar from overheating. Too little oil is evidenced by smoke,  
bar discoloration or pitch build-up.  
C
Fig. 10  
Automatic Oiler  
Your chain saw is equipped with an automatic gear driven  
oiler system. The oiler automatically delivers the proper  
amount of oil to the bar and chain. As the engine speed  
increases, so does the oil flow to the bar pad. The amount  
of oil flowing to the bar and chain may be changed by  
turning the adjustment screw (D) with a small slotted  
screwdriver as shown in Fig. 11. Turn the screw clockwise  
to DECREASE oil flow and counterclockwise to INCREASE  
the flow.

OPERATING INSTRUCTIONS  
FELLING  
Never walk in front of  
a tree that has been  
notched. When felling, keep at least 2 tree  
lengths away from your fellow workers.  
WARNING:  
Felling is the term for cutting down a tree. Small trees up  
to 6-7 inches (15-18cm) in diameter are usually cut in a  
single cut. Larger trees require notch cuts. Notch cuts  
determine the direction the tree will fall.  
Make the felling cut (D) from the other side of the tree and  
1.5 - 2.0 inches (3-5 cm) above the edge of the notch (C)  
(13 9).  
A retreat path (A)  
WARNING:  
should be planned  
and cleared as necessary before cuts are  
started. The retreat path should extend back  
and diagonally to the rear of the expected  
line of fall, as illustrated in Fig. 12.  
If felling a tree on  
CAUTION:  
sloping ground, the  
Hinge  
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.  
NOTE: Direction of fall (B) is controlled by the notching  
cut. Before any cuts are made, consider the loca-  
tion of larger branches and natural lean of the tree  
to determine the way the tree will fall.  
Fig. 13  
Never saw completely through the trunk. Always leave a  
hinge. The hinge guides the tree. If the trunk is completely  
cut through, control over the felling direction is lost.  
Before making the  
WARNING:  
final cut, always recheck  
the area for bystanders, animals or obstacles.  
B
Insert a wedge or felling lever in the cut well before the  
tree becomes unstable and starts to move. This will pre-  
vent the guidebar from binding in the felling cut if you  
have misjudged the falling direction. Make sure no  
bystanders have entered the range of the falling tree  
before you push it over.  
A
Felling Cut:  
1. Use wooden or plastic wedges (G) to prevent binding  
the bar or chain (H) in the cut. Wedges also control  
felling (Fig. 14).  
2. When diameter of wood being cut is greater than the  
bar length, make 2 cuts as shown (Fig. 15).

ing utility wires; notify the utility company  
before making any cuts.  
G
H
Normally felling consists of 2 main cutting operations,  
notching (C) and making the felling cut (D) (Fig. 13).  
Start making the upper notch cut (C) on the side of the  
tree facing the felling direction (E). Be sure you don t make  
the lower cut too deep into the trunk (Fig. 13).  
The notch (C) should be deep enough to create a hinge (F)  
of sufficient width and strength. The notch should be wide  
enough to direct the fall of the tree for as long as possible  
(Fig. 13).

OPERATING INSTRUCTIONS  
When bucking on a slope, always stand on the uphill side.  
1. Log supported along entire length: Cut from top (over-  
buck), being careful to avoid cutting into the ground  
(Fig. 17).  
2. Log supported on 1 end: First, cut from bottom  
(underbuck) 1/3 diameter of log to avoid splintering.  
Second, cut from above (overbuck) to meet first cut  
and avoid pinching (Fig. 18).  
3. Log supported on both ends: First, overbuck 1/3 diame-  
ter of log to avoid splintering. Second, underbuck to  
meet first cut and avoid pinching (Fig. 19).  
NOTE: The best way to hold a log while bucking is to use  
a sawhorse. When this is not possible, the log  
should be raised and supported by the limb  
stumps or by using supporting logs. Be sure the  
log being cut is securely supported.  
Fig. 15  
LIMBING  
Limbing a tree is the process of removing the branches  
from a fallen tree. Do not remove supporting limbs (A) until  
after the log is bucked (cut) into lengths (Fig. 16).  
Branches under tension should be cut from the bottom up  
to avoid binding the chain saw.

B. Keep the left arm as straight as possible.  
C. Keep weight on both feet.  
BUCKING  
Bucking is cutting a fallen log into lengths. Make sure you  
have a good footing and stand uphill of the log when cut-  
ting on sloping ground. If possible, the log should be sup-  
ported so that the end to be cut off is not resting on the  
ground. If the log is supported at both ends and you must  
cut in the middle, make a downward cut halfway through  
the log and then make the undercut. This will prevent the  
log from pinching the bar and chain. Be careful that the  
chain does not cut into the ground when bucking as this  
causes rapid dulling of the chain.  
While the saw is cut-

reduce the possibility of injury due to kick-  
back; however, it cannot provide the intend-  
ed measure of protection if the saw is oper-  
ated carelessly.  
D
Always test the Chain Brake® before using  
your saw and periodically while on the job.  
Your chain saw is equipped with a Chain Brake® that  
reduces possibility of injury due to kickback. The brake is  
activated if pressure is applied against brake lever when,  
as in the event of kickback, operator’s hand strikes the  
lever. When the brake is activated, chain movement stops  
abruptly.  
Fig. 28  
To Test the Chain Brake®:  
2. After making adjustment, and while still holding nose  
of bar in the uppermost position, tighten the bar  
retaining nuts securely. Chain has proper tension when  
it has a snug fit all around and can be pulled around  
by gloved hand.  
1. The Chain Brake® is DISENGAGED (chain can move)  
when BRAKE LEVER IS PULLED BACK AND  
LOCKED (A, Fig. 24).  
2. The Chain Brake® is ENGAGED (chain is stopped)  
when brake lever is in forward position. You should  
not be able to move chain (B, Fig. 30).  
NOTE: If chain is difficult to rotate on guide bar or if it  
binds, too much tension has been applied. This  
requires minor adjustment as follows:  
NOTE: The brake lever should snap into both positions. If  
strong resistance is felt, or lever does not move  
into either position, do not use your saw. Take  
your saw to a Sears or other qualified service  
dealer.  
A. Loosen the bar retaining nuts so they are hand tight.  
Decrease tension by turning the bar adjustment screw  
COUNTERCLOCKWISE slowly. Move chain back and  
forth on bar. Continue to adjust until chain rotates  
freely, but fits snugly. Increase tension by turning bar  
adjustment screw CLOCKWISE.

MAINTENANCE AND REPAIR INSTRUCTIONS  
Sprocket Tip Lubrication  
STORING A CHAIN SAW  
Storing a chain saw for longer than 30 days requires stor-  
age maintenance. Unless the storage instructions are fol-  
lowed, fuel remaining in the carburetor will evaporate,  
leaving gum-like deposits. This could lead to difficult start-  
ing and result in costly repairs.  
1. Remove the fuel tank cap slowly to release any pres-  
sure in tank. Carefully drain the fuel tank by running  
the unit dry or by tipping the motor housing/fuel tank  
over and draining oil/fuel mixture into a container with  
the same 2-cycle fuel mixture.  
The sprocket tip on  
your new saw has  
been pre-lubricated at the factory. Failure to  
lubricate the guide bar sprocket tip as  
explained below will result in poor perform-  
ance and seizure, voiding the manufacturer’s  
warranty.  
CAUTION:  
Lubrication of the sprocket tip is recom-  
mended after 10 hours of use or once a  
week, which ever occurs first. Always thor-  
oughly clean guide bar sprocket tip before  
lubrication.  
2. Start the engine and let it run until the unit stops to  
remove fuel from carburetor.  
3. Allow the engine to cool (approx. 5 minutes).  
4. Using a spark plug wrench, remove the spark plug.  
The Lube Gun (not included) is recommended for applying  
grease to the guide bar sprocket tip. The Lube Gun is  
equipped with a needle nose tip which is necessary for  
the efficient application of grease to the sprocket tip.  
5. Pour 1 teaspoon of clean 2-cycle oil into the combus-  
tion chamber. Pull starter rope slowly several times to  
coat internal components. Replace spark plug (Fig.  
36).  
NOTE: Store the unit in a dry place and away from possi-  
ble sources of ignition such as a furnace, gas hot  
water heater, gas dryer, etc.  
Fig. 37  
To lubricate the sprocket tip:  
1. Move the STOP switch up.  
NOTE: It is not necessary to remove the saw chain to  
lubricate the guide bar sprocket tip. Lubrication  
can be done on the job.  
2. Clean the guide bar sprocket tip.  
3. Using the Lube Gun (not included), insert tip of lube  
gun into the lubrication hole and inject grease until it  
appears at outside edge of sprocket tip (Fig. 37).  
4. Rotate saw chain by hand. Repeat lubrication procedure  
until the entire sprocket tip has been greased.

REMOVING A UNIT FROM STORAGE  
Never store a chain  
CAUTION:  
saw for longer than 30  
days without performing the following proce-  
dures.  
SAW CHAIN / BAR LUBRICATION  
Adequate lubrication of the saw chain is essential at all  
times to minimize friction with the guide bar.  
Never starve the bar and chain of oil. Running the saw  
with too little oil will decrease cutting efficiency, shorten  
saw chain life, cause rapid dulling of chain, and cause  
excessive wear of bar from overheating. Too little oil is evi-  
denced by smoke, bar discoloration or pitch build-up.  
1. Remove spark plug.  
2. Pull starter rope briskly to clear excess oil from com-  
bustion chamber.  
3. Clean and gap spark plug or install a new spark plug  
with proper gap.  
4. Prepare unit for operation.  
5. Fill fuel tank with proper fuel / oil mixture. See Oil and  
Fuel Information.  
NOTE: Saw chain stretches during use, particularly when  
it is new, and it will occasionally be necessary to  
adjust and tighten it. New chain will require adjust-  
ment after about 5 minutes of operation.  
GUIDE BAR MAINTENANCE  
Frequent lubrication of the guide bar (railed bar which  
supports and carries the saw chain) sprocket tip is  
required. Proper maintenance of the guide bar, as  
explained in this section, is essential to keep your saw in  
good working condition.

MAINTENANCE AND REPAIR INSTRUCTIONS  
Chain Lubrication  
GUIDE BAR MAINTENANCE:  
Always make sure the automatic oiler system is working  
properly. Keep the oil reservoir filled with Chain, Bar and  
Sprocket Oil.  
Adequate lubrication of the bar and chain during cutting oper-  
ations is essential to minimize friction with the guide bar.  
Never starve the bar and chain of lubricating oil. Running  
the saw dry or with too little oil will decrease cutting effi-  
ciency, shorten saw chain life, cause rapid dulling of chain,  
and lead to excessive wear of bar from overheating. Too  
little oil is evidenced by smoke or bar discoloration.  
Most guide bar problems can be prevented merely by  
keeping the chain saw well maintained.  
Insufficient guide bar lubrication and operating the saw with  
chain that is too tight will contribute to rapid bar wear.  
To help minimize bar wear, the following guide bar mainte-  
nance procedures are recommended.  
BAR WEAR - Turn guide bar frequently at regular intervals  
(for example, after 5 hours of use), to ensure even wear on  
top and bottom of bar.  
BAR GROOVES (B) Bar grooves (or rails which support  
and carry the chain) should be cleaned if saw has been  
used heavily or if saw chain appears dirty. Rails should  
always be cleaned every time saw chain is removed.  
OIL PASSAGES (A) Oil passages on the bar should be  
cleaned to ensure proper lubrication of the bar and chain  
during operation. This can be done using a soft wire small  
enough to insert into the oil discharge hole.  
Chain Sharpening  
Chain sharpening requires special tools to ensure that cut-  
ters are sharpened at the correct angle and depth. For the  
inexperienced chain saw user, we recommend that the  
saw chain be professionally sharpened by the nearest  
Authorized Service Center. If you feel comfortable sharp-  
ening your own saw chain, special tools are available from  
your Authorized Service Center.

enough to be pulled around by hand.  
Breaking in a New Saw Chain  
A new chain and bar will need chain readjustment after as  
few as 5 cuts. This is normal during the break-in period,  
and the interval between future adjustments will begin to  
lengthen quickly.  
Never have more  
WARNING:  
than 3 links removed  
from a loop of chain. This could cause dam-  
age to the sprocket.

California / EPA Emission Control Warranty Statement  
Your Warranty Rights and Obligations  
The California Air Resources Board, The Environmental Protection Agency and Sears, Roebuck and Co., are pleased to  
explain the emission control system warranty on your 2005 and later small off-road engine. In California and the 49 states,  
new small off-road engines must be designed, built and equipped to meet stringent anti-smog standards. Sears must war-  
rant the emission control system on your small off-road engine for the periods of time listed below provided there has been  
no abuse, neglect or improper maintenance of your small off-road engine.  
Your Emission control system may include parts such as the carburetor or fuel-injection system, the ignition system, and cat-  
alytic converter. Also included may be hoses, belts, connectors and other emission-related assemblies.  
Where a warrantable condition exists, Sears will repair your small off-road engine at no cost to you including diagnosis, parts  
and labor.  
The 2005 and later small off-road engines are warranted for two years. If any emission-related part on your engine is  
defective, the part will be repaired or replaced by Sears.  
Owner’s Warranty Responsibilities  
• As the small off-road engine owner, you are responsible for the performance of the required maintenance listed in your  
operator’s manual. Sears recommends that you retain all receipts covering maintenance on your small off-road engine, but  
Sears cannot deny warranty solely for the lack of receipts or for your failure to ensure the performance of all scheduled  
maintenance.  
• As the small off-road engine owner, you should however be aware that Sears may deny you warranty coverage if your small  
off-road engine or a part has failed due to abuse, neglect, improper maintenance or unapproved modifications.  
You are responsible for presenting your small off-road engine to a Sears authorized service center as soon as problem  
exists. The warranty repairs should be completed in a reasonable amount of time, not to exceed 30 days.  
If you have any questions regarding your warranty rights and responsibilities, you should call 1-800-4-MY-HOME®.  
Manufacturer’s Warranty Coverage  
• The warranty period begins on the date the engine or equipment is delivered to the retail purchaser.  
• The manufacturer warrants to the initial owner and each subsequent purchaser, that the engine is free from defects in mate-  
rial and workmanship which cause the failure of a warranted part for a period of one year.  
• Repair and replacement of warranted part will be performed at no charge to the owner at an authorized Sears service cen-  
ter. For the nearest location please contact Sears at: 1-800-4-MY-HOME®.  
• Any warranted part which is not scheduled for replacement, as required maintenance or which is scheduled only for regu-  
lar inspection to the effect of “Repair or Replace as Necessary” is warranted for the period. Any warranted part which is  
scheduled for replacement as required maintenance will be warranted for the period of time up to the first scheduled  
replacement point for that part.  
• The owner will not be charged for diagnostic labor which leads to the determination that a warranted part is defective if the  
diagnostic work is performed at an authorized Sears Service Center.  
• The manufacturer is liable for damages to other engine components caused by the failure of a warranted part still under  
warranty.  
• Failures caused by abuse, neglect or improper maintenance are not covered under warranty.  
• The use of add-on or modified parts can be grounds for disallowing a warranty claim. The manufacturer is not liable to cover  
failures of warranted parts caused by the use of add-on or modified parts.  
• In order to file a claim, go to your nearest authorized Sears Service Center. Warranty service or repairs will be provided at  
all authorized Sears Service Centers.  
• Any manufacturer approved replacement part may be used in the performance of any warranty maintenance or repair of  
emission related parts and will be provided without charge to the owner. Any replacement part that is equivalent in perform-  
ance or durability may be used in non-warranty maintenance or repair and will not reduce the warranty obligations of the  
manufacturer.  
• The following components are included in the emission related warranty: engine, air filter, carburetor, primer, fuel lines, fuel  
pick up/fuel filter, ignition module, spark plug and muffler.
