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

instructions 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 leads to

formation 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:

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.

system with MAX FIRE IGNITION™, which signifi-

cantly reduces the effort required to start the engine.

You must pull the starter rope out far enough to hear

the engine attempt to start. There is no need to pull

the rope briskly--there is no harsh resistance when

pulling. Be aware that this starting method is vastly

different from (and much easier than) what you may

be used to.

5. Pull starter 4 to 6 times-when unit starts move choke

to position 3. If unit fails to start move choke to posi-

tion 2 and pull 4-6 times until it starts. (Fig.13 & 14 )

6. Once engine starts move choke to position 3.

7. After unit starts apply 1/4 throttle slightly and slowly

then allow engine to warm up for 30 seconds.

8. Pull throttle to run.

Fig. 12

NOTE: If engine fails to start after repeated attempts,

refer to Troubleshooting section.

NOTE: Always pull starter rope straight out. Pulling

starter at an angle will cause rope to rub against the eye-

let. This friction will cause the rope to fray and wear more

quickly. Always hold starter handle when rope retracts.

Never allow rope to snap back from extended position.

This could cause rope to snag or fray and also damage

the starter assembly.

COLD STARTS (below 55˚F)

1. Switch to “RUN (I)” position.

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 two years.

• 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.
