RESTRICT THE USE OF THIS POWER UNIT TO PERSONS WHO READ, UNDERSTAND AND FOLLOW THE WARNINGS AND INSTRUCTIONS IN THIS MANUAL AND ON THE UNIT. BLADE THRUST- WHEN THE SPINNING BLADE CONTACTS ANYTHING IT CANNOT CUT, A DANGEROUS REACTION MAY OCCUR CAUSING THE ENTIRE UNIT AND OPERATOR TO BE THRUST VIOLENTLY IN ANY DIRECTION. THIS REACTION IS CALLED BLADE THRUST. AS A RESULT, THE OPERATOR CAN LOSE CONTROL OF THE UNIT. USE HANDLEBAR, SHOULDER HARNESS, AND KEEP METAL BLADE SHIELD IN PLACE, MAKE SURE OTHERS ARE AT LEAST 50 FEET (15 METERS) AWAY. KEEP BLADE SHARP. CUT AT FULL THROTTLE AND FROM YOUR RIGHT TO LEFt. KEEP HANDS, FEET AND UNIT IN PROPER POSITION; REFER TO "GUARD AGAINST BLADE THRUST," PROPER BLADEUSE ONLY THE 8 °'BRUSH BLADE OR 8" WEED BLADE AND PROPER HARDWARE AS SHOWN. THE USE OF ANY OTHER PARTS CAN RESULT IN SERIOUS INJURY. DO NOT USE ANY ACCESSORY OR ATTACHMENT OTHER THAN THOSE RECOMMENDED BY THE MANUFACTURER FOR USE WITH THIS UNIT. BLADES THAT ARE BENT, WARPED, CRACKED, BROKEN, OR DAMAGED CAN FLY APART AND CAUSE SERIOUS INJURY, DO NOT USE; THROW AWAY, BLADE THRUST IS a reaction that only occurs when using a bladed unit. This reaction can cause serious injury such as amputation. Carefully study this section. Itis importantthat you understandwhat causes blade thrust,how you can reducethe chance of it occurring, and how you can remain in controlof the unit if blade thrustoccurs. WHAT CAUSES BLADE THRUST? Blade Thrustcanoccurwhen thespinningbladecontacts an object that it does not cut. This contact causes the bladeto stop for an instantand then suddenlymove or "thrust"away fromthe objectthatwas hit.The "thrusting" reaction can be violentenough to cause the operator to be propelled in any direction and Josecontrolotthe unit. The uncontrolledunitcan cause sedous injuryif the blade contacts the operator or others. WHEN DOES BLADE THRUST OCCUR? Blade thrust can occur without warning if the blade snags, stalls, or binds. This ismore likelyto occurin areas where it isdifficultto see the matedal beingcut. By using the unit properly, the occurrenceof blade thrustwill be reduced and the operator will be less likelyto lose control. The forward tip on the metal bladeshieldhelpsto reduce the occurrence of blade thrustbut cannot prevent the occurrence. The operator must follow all warnings and safety instructionsin this manual to lessen the chance of blade thrustoccurringand to maintain controlof unit if the reactiondoes occur. -14- 8" WEED BLADE ARBOR (20MM) 8" BRUSH BLADE REDUCE THE CHANCE OF BLADE THRUST • Cut vegetation up to 2 1/2" diameter saplingswith saw blade. • Cut onlygrass,weeds, and woodybrushup to 1/2" in diameterwiththebrushtri-blade.

This oil is specially blended with fuel stabilizersfor increased fuel stability(extends fuel life up to 5 times longer) and reduced smoke. BE SURE TO READ THE FUEL SAFETY WARNING: INFORMATION IN THE SAFETY RULES SECTION ON PAGE 2 OF THIS MANUAL BEFORE YOU BEGIN. If CRAFTSMAN 40:1 2-cycle engine oil (AIR-COOLED) is not available, use a good quality 2-cycle engine oil (AIR-COOLED) that has a recommended fuel mix ratio of 40:t, IF YOU DO NOT UNDERSTAND THE FUEL SAFETY SECTION DO NOT ATTEMPT TO FUEL YOUR UNIT; SEEK HELP FROM SOMEONE WHO DOES UNDERSTAND THE FUEL SAFETY SECTION OR CALL THE CUSTOMER ASSISTANCE-HOTLINE AT 1-800-235-5878. IMPORTANT! Do no use: • AUTOMOTIVE OIL • BOAT OILS (NMMA, BIA, etc.) GASOLINE The two-cycle engine on this product requires a fuel mixture of regular unleadedgasoline and a high quality 40:1 2-cycle engine oil (AIR-COOLED) for lubrication of the bearings and other movingparts.The correct fuel/oil mixture is 40:1 (see Fuel Mixture Chart). Too little oil or the incorrect oil type will cause poor performance and may cause the engine to overheatand seize. Gasoline and oil must be premixed in a clean approved fuel container. Always use fresh regular unleaded gasoline. This engine is certified to operate on unleaded gasoline. IMPORTANT: Experience indicates that alcohol blended fuels called gasohol (or using ethanol or methanol) can attract moisture, which leads to oil/gas 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, then run the fuel out of the carburetor and fuel lines by starting the engine and letting it run until it stops.Use fresh fuel next season. See STORAGE instructions for additional information. Never use engine or carburetor cTeanerproducts in the fuel tank or permanent damage may occur, These oils do not have proper additives for 2-cycle AIRCOOLED engines and can cause engine damage. GASOLINE AND OIL MIXTURE Mix gasolineand oi! as follows: ° Consuifchart for correct quantities. • Do not mix gasoline and oil directly in the unit's fuel tank. FOR ONE GALLON: • Pour 3.2 ounces of high quality, 40:1 2-cycle engine oit (AIR-COOLED) into an empty, approved one gallon gasoline container. • Add one gallon of regular unleaded gasoline to the gallon container, then securely replace thecap. • Shake the container. • The mixture is now ready for use. Fuel stabilizer can be added at this time if desired; follow mixing instructions on the label. FUEL MIXTURE CHART 40:1 Fuel:Oil Mix Ratio 1 gallon 2.5 gallons Oil {fl.oz.) 3.2 8.0 f FUEL STABILIZER Fuel stabilizer is an acceptable alternative in minimizing the formation of fuel gum deposits during storage. Add stabilizer to gasoline in fuel tank or storage container. Always follow the fuel tank or storage container. Always follow the fuel mix ratiofound on the stabilizer container. Run engine at least 5 minutesafter adding stabilizer to ailow the stabilizer to reach the carburetor. You do not have to drain the fuet tank for storage if you are using fuel stabilizer. CRAFTSMAN 40:1 2-cycle engine oil (AIR-COOLED) is specially blended with fuel stabilizers. If you do not use this Sears oil, you can add a fuel stabilizer (such as CRAFTSMAN No.33500) to your fuel tank. -18- NOTE: Fuel containers may hold more than the specified amount. If too much gasoline is in the container, the resulting gas-to-oil fuel mixture witl not be correct for properengine operation. ||11| i ......

THE CAUTION: WEAR PROTECTIVE BLADE IS SHARP AND CAN CUTGLOVES YOU. -30. i i I Ill! i i ii illll | III FUEL SYSTEM Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur to fuel system components. Followthese instructions: • Drain the fuel from the unit into an approved fuel container. • Drain the fuel lines and carburetor by starting the : engine and letting it run until it stops. • Allow the engine to cool before storage. IMPORTANT: It is important to prevent gum deposits from forming in essential fuel system parts such as the carburetor, fuel filter, fuel hose or tank during storage. Also, experience indicates that alcohol blended fuels, those that use ethanol or methanol (called gasohol or oxygenated fuel), can attract moisture and form acidic gas which will damage your engine. To avoid engine problems, the fuel system should be emptied before storage of 30 days or longer. Fuel stabilizer is an acceptable alternative in minimizing the formation of fuel gum deposits during storage. Add stabilizer to the gasoline in the fuel tank or fuel storage container. Always follow the mix instructions found on stabilizer containers. Run engine at least 5 minutes after adding stabilizer to allow the stabilizer to reach the carburetor. CRAFTSMAN 40:1 2-cycle engine oil (AIR-COOLED) is specially blended with fuel stabilizer.If you do not use this Sears oil, you can add a fuel stabilizer (such as CRAFTSMAN No, 33500) to your fuel tank. INTERNAL ENGINE • Remove spark plug and pour 1 teaspoon of 40:1 2-cycle engine oil (AIR-COOLED) through the spark plug opening. Slowly pull the starter rope 8 to 10 times to distribute oil to Inner engine surfaces. • Replacespark plugwith a new one of the recommended type and heat range. Referto "Product Specifications". • Clean air filter. Refer to "Customer Responsibilities". • Re-install all covers and hardware removed for access; tighten all screws and fasteners. • Check entire unit for loose screws, nuts, and bolts. Replace any damaged, broken, or worn parts. • Lightlyoil extemal metal surface to prevent rust from forming. • Use fresh fuel having the proper gasoline to oil ratio at the beginningof the next season. OTHER - Do not store gasolinefrom one season to another. • Replace your gasoline can if your can starts to rust. Rust and/or dirt in your fuel system will cause problems. • Store your unit in a well ventilated area and covered, if possible, to prevent dust and dirt accumulation. Do not cover with plastic. Plastic cannot breathe and will induce condensationand eventual rust or corrosion. IMPORTANT: NEVER COVER UNIT WHILE ENGINE AND EXHAUST AREAS ARE STILL WARM. iiii iiii i i ....
