OIL AND FUEL INFORMA TION OIL AND FUEL MIXING INSTRUCTIONS Old and/or improperly mixed fuel ar e the main r easons 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 pr oper fuel/oil mixtur e. Definition of Blended Fuels T oday's fuels ar e 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. Using Blended Fuels If you choose to use a blended fuel, or its use is unavoid- able, follow recommended pr ecautions: ⢠Always use the fresh fuel mix explained in your opera- tor's manual ⢠Always agitate the fuel mix before fueling the unit ⢠Drain the tank and run the engine dry before storing the unit 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. If unavailable, use a good 2-cycle oil designed for air -cooled engines along with a fuel additive, such as ST A-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. To Obtain Correct Fuel Mix: Thoroughly mix the pr oper 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. NOTE: One gallon (3.8 liters) of unleaded gasoline mixed with one 3.2 oz. (95 ml.) bottle of 2-cycle oil makes a 40:1 fuel/oil ratio. NOTE: Dispose of the old fuel/oil mix in accordance to Federal, State and Local regulations. For proper engine operation and maxi- mum reliability , pay strict attention to the oil and fuel mixing instructions on the 2-cycle oil container . Using improperly mixed fuel can severely damage the engine. CAUTION: UNLEADED GAS 2 CYCLE OIL 1 GALLON US (3.8 LITERS) 3.2 FL. OZ. (95 ml) 1 LITER 25 ml MIXING RA TIO - 40:1 Gasoline is extremely flamma- ble. Ignited V apors may explode. Always stop the engine and allow it to cool before filling the fuel tank. Do not smoke while fill- ing the tank. Keep sparks and open flames at a distance from the ar ea. W ARNING: Remove fuel cap slowly to avoid injury from fuel spray . Never operate the unit without the fuel cap securely in place . W ARNING: Add fuel in a clean, well ventilated out- door area. Wipe up any spilled fuel immedi- ately . Avoid cr eating a sour ce of ignition for spilled fuel. Do not start the engine until fuel vapors dissipate. W ARNING: 8

ST AR TING/STOPPING INSTRUCTIONS NOTE: The unit uses the INCREDI-PULL⢠starting system with MAX FIRE IGNITION⢠, which signifi- cantly reduces the ef fort r equired to start the engine. Y ou must pull the starter r ope out far enough to hear the engine attempt to start. There is no need to pull the rope briskly--ther e is no harsh r esistance when pulling. Be aware that this starting method is vastly differ ent fr om (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.

OIL AND FUEL INFORMA TION OIL AND FUEL MIXING INSTRUCTIONS Old and/or improperly mixed fuel ar e the main r easons 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 pr oper fuel/oil mixtur e. Definition of Blended Fuels T oday's fuels ar e 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. Using Blended Fuels If you choose to use a blended fuel, or its use is unavoid- able, follow recommended pr ecautions: ⢠Always use the fresh fuel mix explained in your opera- tor's manual ⢠Always agitate the fuel mix before fueling the unit ⢠Drain the tank and run the engine dry before storing the unit 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. If unavailable, use a good 2-cycle oil designed for air -cooled engines along with a fuel additive, such as ST A-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. To Obtain Correct Fuel Mix: Thoroughly mix the pr oper 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. NOTE: One gallon (3.8 liters) of unleaded gasoline mixed with one 3.2 oz. (95 ml.) bottle of 2-cycle oil makes a 40:1 fuel/oil ratio. NOTE: Dispose of the old fuel/oil mix in accordance to Federal, State and Local regulations. For proper engine operation and maxi- mum reliability , pay strict attention to the oil and fuel mixing instructions on the 2-cycle oil container . Using improperly mixed fuel can severely damage the engine. CAUTION: UNLEADED GAS 2 CYCLE OIL 1 GALLON US (3.8 LITERS) 3.2 FL. OZ. (95 ml) 1 LITER 25 ml MIXING RA TIO - 40:1 Gasoline is extremely flamma- ble. Ignited V apors may explode. Always stop the engine and allow it to cool before filling the fuel tank. Do not smoke while fill- ing the tank. Keep sparks and open flames at a distance from the ar ea. W ARNING: Remove fuel cap slowly to avoid injury from fuel spray . Never operate the unit without the fuel cap securely in place . W ARNING: Add fuel in a clean, well ventilated out- door area. Wipe up any spilled fuel immedi- ately . Avoid cr eating a sour ce of ignition for spilled fuel. Do not start the engine until fuel vapors dissipate. W ARNING: 8

ST AR TING/STOPPING INSTRUCTIONS NOTE: The unit uses the INCREDI-PULL⢠starting system with MAX FIRE IGNITION⢠, which signifi- cantly reduces the ef fort r equired to start the engine. Y ou must pull the starter r ope out far enough to hear the engine attempt to start. There is no need to pull the rope briskly--ther e is no harsh r esistance when pulling. Be aware that this starting method is vastly differ ent fr om (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 thr ottle slightly and slowly then allow engine to warm up for 30 seconds. 8. Pull thr ottle to run. NOTE: If engine fails to start after repeated attempts, refer to T roubleshooting 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 mor e quickly . Always hold starter handle when rope r etracts. Never allow rope to snap back fr om extended position. This could cause rope to snag or fray and also damage the starter assembly . COLD ST ARTS (below 55 Ë F) 1. Switch to âRUN (I)â position. 2. Prime 10 times. 3. Choke in position â â. 4. Do not press thr ottle lock or trigger . 5. Pull rope until engine starts should be 1-10 times. 6. Move choke to position â â. 7. After unit starts apply 1/4 throttle slightly and slowly then allow engine to warm up for 30 seconds. 8. Press trigger to run. IMPORT ANT IDLING INFORMA TION In some cases due to operating conditions (altitude, tem- perature etc.) your blower may need a slight adjustment to the idle speed. After warm up, If unit does not Idle after restarting 2 times, follow these steps to adjust idle. 1. Locate the idle adjustment scr ew (G) on the carbure- tor (Figure 15). 2. Using a Phillips or slotted scr ewdriver - turn screw 1/4 to 1/2 turn clockwise (to the right). Unit should then idle properly . STOPPING THE ENGINE Emergency Stopping Procedur e. When it is necessary to stop blower engine immediately , DEPRESS the OFF âSTOP â switch (A) until the engine stops completely (Figure 16). Normal Stopping Method. For normal stopping, release trigger and allow engine to return to idle speed. Then DEPRESS the OFF âSTOP â switch (A) until the engine stops completely . (Figure 16) ST ARTING A WARM ENGINE (Engine has been stopped for no more than 15-20 minutes). 1. Set throttle latch (see step 2 for starting a cold engine), pull starter rope briskly . 2. If engine does not start, or starts and then stops after 5 rope pulls, follow pr ocedur e âST ARTING A COLD ENGINEâ. Fig. 12 Fig. 13 Fig. 14 Fig. 15 11 1 2 3 1 3 G 2 Fig. 16 A

In California and the 49 states, new small off-r oad engines must be designed, built and equipped to meet stringent anti-smog standar ds. Sears must war- rant the emission control system on your small of f-r oad engine for the periods of time listed below provided ther e has been no abuse, neglect or improper maintenance of your small of f-r oad engine. Y our Emission contr ol system may include parts such as the carbur etor 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 r epair your small of f-r oad engine at no cost to you including diagnosis, parts and labor . The 2005 and later small off-r oad engines ar e warranted for two years. If any emission-related part on your engine is defective, the part will be repair ed or r eplaced by Sears. Ownerâ s Warranty Responsibilities ⢠As the small off-r oad engine owner , you are r esponsible for the performance of the r equired maintenance listed in your operatorâ s manual. Sears recommends that you r etain all r eceipts covering maintenance on your small off-r oad engine, but Sears cannot deny warranty solely for the lack of receipts or for your failur e to ensur e the performance of all scheduled maintenance. ⢠As the small off-r oad engine owner , you should however be aware that Sears may deny you warranty coverage if your small off-r oad engine or a part has failed due to abuse, neglect, impr oper maintenance or unapproved modifications. ⢠Y ou ar e responsible for pr esenting your small of f-road engine to a Sears authorized service center as soon as pr oblem exists. The warranty repairs should be completed in a r easonable amount of time, not to exceed 30 days. If you have any questions regar ding your warranty rights and r esponsibilities, you should call 1-800-4-MY -HOME®. Manufacturerâ s W arranty Coverage ⢠The warranty period begins on the date the engine or equipment is delivered to the r etail pur chaser . ⢠The manufacturer warrants to the initial owner and each subsequent pur chaser , that the engine is free fr om 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 char ge 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 r equir ed maintenance or which is scheduled only for regu- lar inspection to the effect of âRepair or Replace as Necessaryâ is warranted for the period. Any warranted part which is scheduled for replacement as r equir ed maintenance will be warranted for the period of time up to the first scheduled r eplacement point for that part. ⢠The owner will not be char ged 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 failur e of a warranted part still under warranty . ⢠Failures caused by abuse, neglect or impr oper maintenance ar e not covered under warranty . ⢠The use of add-on or modified parts can be grounds for disallowing a warranty claim. The manufactur er 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 near est authorized Sears Service Center . W arranty service or r epairs will be provided at all authorized Sears Service Centers. ⢠Any manufacturer appr oved r eplacement part may be used in the performance of any warranty maintenance or repair of emission related parts and will be pr ovided without char ge to the owner .
