USE THE FOLLOWING: SEARS CRAFTSMAN 2-cycle engine oil _ed at 40:1 is strongly recommended_ Consult the instructions on oil container for proper mixing. 1 PART OIL TO 40 PARTS GASOLINE= 3.2 ft. oz. oil to i gallon gasoline 8.0 ft. oz. oil to 2.5 gallon gasoline Not all air cooled 2-cycle engine oils have the same qualities. If SEARS CRAFI'SMAN 2-_cle engine_ oil is not available, use a good quality, 2-cycle engine oil recommended for air-cooled engines. Mix at a ratio of 16:1 (8 oz. oil to I gallon gasoline). A 16:1 fuet mixture with these oils will assure adequate lubrication for .....your engine. a. Use only recommended fuel mixtures. b. Mix and pour fuel outdoors and where there are no sparks or flames. c. Use a container approved for fuel. d. Do not smoke or allow smoking near fuel •or the unit or while using the unit. e. Wipe up all fuel spills before starting the engine. £ Move at least 10 feet (3 meters) away from fueling site before starting engine. g. Stop engine before removing fuel cap. Allow engine to cool before refueling. h. Before storing the unit, use up fuel left in ..... the fuel lines and carburetor by starting the engine and letting it _.Jn until it stops. i. Store unit and fuel m an area where fuel vapors cannot reach sparks or open flames from water heaters, electric motors or switches, furnaces, etc. 4. DO NOT USE: • 2. FUEL MIXTURE Marine Manufac(formerly BIA oil)-- ..... A CAUTION Experience indicates that alcohol blended fuels (tailed gasohol or using ethanol or methanol) can attract moisturewhich 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, do not leave fuel in the unit when storing for 30 days or longer. Start the engineand let it run until the fuel lines and carburetor are empty. Use fresh fuel next season. See the "Storage" section for additional information. Never use engine or carburetor cleaner products in the fuel tank or permanent damage can occur. 5. HOW TO MIX FIlL r _k" _l t_ :in ::: : Oil--National Association • AUTOMOTIVE OIL-Does not have proper additives for air-cooled0 2-cycle engines and can cause engine damage. e. Your unit is powered by a 2-cycle engine which requires a fuel mixture of regular unleaded gas?!ine and a high quality engine oil spemally made for 2-cycle, air cooled engines. The internal design of the 2-cycle engine requires lubrication of moving parts. Lubrication is provided when the recommended mixture of gasoline and oil is used. b. Genuine Sears 40:1, 2-cycle engine oil is strongly recommended for the protection of your unit. Extensive englneeringtests have proven that Sears 2-cycle engine oil resists break-down at operating temperatures common to 2-cycle engines, resulting in dependable performance and longer engine life. c. Gasoline must be clean and not over two months old. After a short period of time, gasoline wilt chemically break down and form compounds thatcausehard starting and dami age m 2-cycle engines. d. The correct measure of gasoline to oil is very important. Too much oil in the mixture will foul the spark plug. _ Too little oil or incorrect oil _iwill cause engine to overheat and seize. e_i:_ Always mi_ the fuel thoroughly in a con: ii tainer since gasoline and oil do not readily ::: combine. Do not mix gasoline and oil directly B. PRE-OPERATION NMM turers CHECKS .......................................... .....

CUTTING The trimmer line will advance approximately 2 inches each time the bottom oft.he trimmer head is tapped on the ground with theengine running at full throttle. • The most efficient llne length is the maximum length allowed by the line limiter. • Always keep the shield in place when tool zs being operated. Figure 10. • To Advance Line: • 3. Tap the bottom of the trimmer head lightly on the ground one time. See Figure 10. Approximately 2 inches of line will be advancedwith each tap. NOTE__:Always tap the trimmer head on a grassy area. Tapping on surfaces such as concrete or asphalt can cause excessive wear to the trimmer head. • The line will easily remove grass and weeds from around walls, fences, trees and flower beds, but it also can cut the tender bark of trees or shrubs and scar fences. To help avoid damage especia_y to delicate vegetation or trees with tender bark, shorten line to 4-5 inches and use at less than _ throttle.

NOTE: If the line is worn down to two inches or less, more than one tap win be required to obtain the most efficient line length. Cuts Line II The tip of the line does the cutting. You will achieve the best performance and minimum line wear by not crowding the Hne into the cutting area. The right and wrong ways axe shown in Figure 11. 1. Operate the engine at fu!l throttle. 2. Hold the trimmer head pamllet to and above Line _ter III ] A WARNING [ Use _um speed and do not crowd the line[ when cutting around hard objects (rock, gravel, J fenceposts, etc), which can damage the trimmerl head, become entangled in the line, or be[ thrown causing a serious hazard.

Hold the bottom of the trimmer head about 3 inches above the ground _ and at an angle. Allow only the tip of the line to make contact. Do not force the trimmer line into the work area. •:TRIMMING 3 Inches" Above Ground Figure 12 SCALPING - FIGURE 13. The scalping technique removes unwanted vegetation. Hold the bottom of the trimmer head about 3 inches above the ground and at an angle. Allow the tip of the line to strike the ground around trees, posts, monuments, etc. This technique increases line 2_ wear, Figure 13 . MOWINGfor mowing Figure 14. Your trimmer is ideal in places conventional lawn mowers MOWING cannot reach. In the mowing position, keep the line parallel to the ground. Avoid pressing the head into the ground as this can scalp the ground and damage the too!. Figure 14 J 1 SWEEPING - Figure 15.
