If you do not understand the safety rules, do not attempt to fuel your unit. Call 1-800-235-5878. FUELING Experience indicates that alcohol blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage. ENGINE This engine is certified to operate on unleaded gasoline. Before operation, gasoline must be mixed with a good quality 2-cycle air-cooled engine oil. We recommend Craftsman brand oil. To avoid engine problems, empty the fuel system before storage for 30 days or longer. Drain the gas tank, start the engine and let it run until the fuel lines and carburetor are empty. Use fresh fuel next season. Mix gasoline and oil at a ratio of 40:1 (A 40:1 ratio is obtained by mixing 3.2 ounces of oil with 1 gallon of unleaded gasoline). DO NOT USE automotive oil or boat oil. These oils will cause engine damage. When mixing fuel, follow instructions printed on container. Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur. See the STORAGE section for additional information. 9 STOPPING YOUR ENGINE Starter _,.

While the lockout lever is depressed, squeeze and hold the throttle trigger. Lock Button _/ Throttle Trigger Lockout Lever _C__'_Z_,_ • Before releasing the throttle trigger, press the lock button. While this button is still depressed release the throttle trigger. NOTE: This should allow the throttle trigger to remain in the depressed position for starting. You may want to practice this a few times before you first start the unit. • DO NOT squeeze throttle trigger during starting; otherwise, it will be necessary to reset the throttle lock. COLD ENGINE OR WARM ENGINE AFTER RUNNING OUT OF FUEL WARNING: The blade or trimmer head will turn while starting the engine. Avoid any contact with the muffler. A hot muffler can cause serious burns. • Rest engine and shield on ground, supporting trimmer head off ground. • Move the switch to the on position. • Slowly press the primer bulb 6 times. • Move choke to Full Choke position. Primer Bulb • Set the throttle trigger in the starting postion using the throttle lock feature. Keep throttle trigger in the starting position until the engine runs smoothly. • Pull starter rope sharply until engine attempts to run or 5 times. • Move choke lever to Half Choke. • Pull starter rope sharply until engine runs, but no more than 6 pulls. NOTE: If the engine has not started after 6 pulls (at half choke), check to make sure the choke lever is in the proper position. Then, move the choke to the Full Choke position and press the primer bulb 6 times; pull the starter rope 2 more times. Move the choke lever to Half Choke and pull the starter rope until the engine runs, but no more than 6 more pulls. If the engine still has not started, it is probably flooded. Proceed to "Starting a Flooded Engine." • Allow the engine to run 10 seconds, then move choke lever to Off Choke. Let the engine run 30 more seconds at Off Choke before releasing the throttle lock. Release throttle lock by squeezing and releasing the trigger. STARTING A WARM ENGINE • Move the switch to the on position, and choke to Half Choke position. • Set the throttle trigger in the starting postion using the throttle lock feature. Keep throttle trigger in the starting position until the engine runs smoothly. • Pull starter rope sharply until engine runs, but no more than 5 pulls. • Allow engine to run 15 seconds, then move the choke lever to Off Choke. NOTE: If engine has not started, pull starter rope 5 more pulls. If engine still does not run, it is probably flooded. 10 DIFFICULT STARTING OR STARTING A FLOODED ENGINE Flooded engines can be started by moving choke lever to Off Choke; then, pull the rope to clear the engine of excess fuel. This could require pulling the starter handle many times depending on how badly the unit is flooded. If the unit still doesn't start, refer to TROUBLESHOOTING chart or call 1-800-235-5878. OPERATING POSITION Control Handle in Right Hand Position Operating Clip shoulder strap onto clamp and stand to operating position. • Arms extended with hands holding the handlebar grip. • Right hand holding control handle, with fingers on throttle trigger. • Engine below waist level. • Shoulder strap pad centered on left shoulder. • Danger sign centered on your back. • Full weight of tool on left shoulder. • Without operator bending over, the blade or semi-automatic head is near and parallel to the ground and easily contacts material to be cut. OPERATING INSTRUCTIONS FOR USE WITH TRIMMER HEAD Bring the engine to cutting speed before entering the material to be cut. Do not run engine at a higher speed than necessary. The cutting line will cut efficiently when engine is run at less than full throttle. At lower speeds, there is less engine noise and vibration. The cutting line will last longer and will be less likely to "weld" onto the spool. If the trimmer head does not turn when the engine is in operation, make sure the drive shaft housing is properly seated in engine shroud. Always release the throttle trigger and allow the engine to return to idle speed when not cutting. To stop engine: • Release the throttle trigger. • Move the On/Stop switch to the STOP position. • If engine does not stop, move choke to the Full Choke position. ADVANCING THE TRIMMER LINE The trimmer line will advance approximately 2 in. (5 cm) each time bottom of trimmer head is tapped on the ground with the engine running at full throttle. The most efficient line length is the maximum length allowed by line limiter. Always keep the shield in place when the tool is being operated. To Advance Line: • Operate the engine at full throttle. • Hold the trimmer head parallel to and above the grassy area. • Tap bottom of trimmer head lightly on ground one time. Approximately 2 in. (5 cm) of line will be advanced with each tap. The line limiter on the shield will cut line to the correct length. "_¥ _C__:<" .,he Umiter 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. If line is worn down to 2 in. (5 cm) or less, more than one tap will be required to obtain the most efficient line length. WARNING: Use only .095" (2.4 mm) diameter line. Other sizes of line will not advance properly and can cause serious injury. Do not use other materials such as wire, string, rope, etc. Wire can break off during cutting and become a dangerous missile that can cause serious injury. CUTTING METHODS WARNING: Use minimum speed and do not crowd the line when cutting around hard objects (rock, gravel, fence posts, etc.), which can damage the trimmer head, become entangled in the line, or be thrown causing a serious hazard. 11 • Thetipofthelinedoes thecutting.

TipoftheLine I Line Crowded into Does TheCutting Work Area Right :"_:_'-"_,1 Wrong = " posts, monuments, etc. This technique increases line wear. Scalping MOWING '" • 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 especially to delicate vegetation or trees with tender bark, shorten line to 4-5 in. (10-13 cm) and use at less than full throttle. • For trimming or scalping, use less than full throttle to increase line life and decrease head wear, especially: • During light duty cutting. • Near objects around which the line can wrap such as small posts, trees or fence wire. • For mowing or sweeping, use full throttle for a good clean job. WARNING: Always wear eye protection. Never lean over the trimmer head. Rocks or debris can ricochet or be thrown into eyes and face and cause blindness or other serious injury. TRIMMING - Hold the bottom of the trimmer head about 3 in. (8 cm) above the ground and at an angle. Allow only the tip of the line to make contact. Do not force trimmer line into work area. Trimming il > - Your trimmer is ideal for mowing in places conventional lawn mowers cannot reach. In the mowing position, keep line parallel to ground. Avoid pressing head into ground as this can scalp ground and damage tool. Mowing SWEEPING - The fanning action of rotating line can be used for a quick and easy clean up. Keep line parallel to and above the surfaces being swept and move the tool from side to side. _/- _.z OPERATING INSTRUCTIONS FOR USE WITH A BLADE • 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. It is important that you understand what causes blade thrust, how you can reduce the chance of its occurring, and how you can remain in control of unit if blade thrust occurs. • WHAT CAUSES BLADE THRUST Blade Thrust can occur when spinning blade contacts an object that it does not cut. This contact causes blade to 3 in. (8 cm) ;'_"_.":'_"_=--,_ 2 2, Above Ground _i_l_._,_" _" stop for an instant and then suddenly move or "thrust" away from object that was hit.

CARBURETOR ADJUSTMENT WARNING: The trimmer head or blade will be spinning during most of this procedure. Wear protective equipment and observe all safety precautions. After making mixture adjustments, recheck idle speed. Carburetor adjustment is critical and if done improperly can permanently damage the engine as well as the carburetor. If you require further assistance or are unsure about performing this procedure, call our customer assistance help line at 1-800-235-5878. Old fuel, a dirty air filter, a dirty fuel filter, or flooding may give the impression of an improperly adjusted carburetor. Check these conditions before adjusting the carburetor. The carburetor has been carefully set at the factory. Adjustments may be necessary if you notice any of the following conditions: • Engine will not idle. See "Idle Speed" under adjusting procedure. • Engine dies or hesitates instead of accelerating. See "Acceleration Check" under adjusting procedure. • Loss of cutting power. See "Mixture Adjustment" under adjusting procedure. There are three adjustment screws on the carburetor. The low speed adjustment screw is marked with the letter L, and the high speed adjustment screw is marked with the letter H. The third screw is the idle adjustment screw. L Screw Idle Adjustment CARBURETOR PRESETS When making carburetor preset adjustments, do not force plastic limiter caps beyond stops or damage will occur. If carburetor presets are not needed, proceed to "Adjusting Procedure, Idle Speed." To adjust presets: • Turn both mixture screws counter- clockwise to the midpoint between the limiter cap stops. • Turn the idle speed screw clockwise until it stops. Now turn counterclockwise 4-1/2 turns. • Start motor, cut grass for 3 minutes, and proceed to the adjustment section. If engine does not start, refer to troubleshooting chart or call 1-800-235-5878. • If engine performance is acceptable at the preset positions, no further adjustment is necessary. ADJUSTING Idle Speed PROCEDURE Adjustment Allow engine to idle. Adjust speed until engine runs without stalling. • Allow engine to idle. Be sure trimmer line is extended to the maximum length allowed by the line limiter. • Adjust idle speed screw until engine continues to run without stalling. • Turn the screw clockwise to increase engine speed if the engine stalls or dies. • Turn screw counterclockwise to slow engine down. • Follow instructions in "Acceleration Check." • No further adjustments are necessary if performance is satisfactory and trimmer head does not turn at idle speed. Low Speed Adjustment "L" When making carburetor adjustments, do not force plastic limiter caps beyond stops or damage will occur. • Allow the engine to idle. • Turn screw "L" slowly clockwise until the speed begins to drop. Note the position of the screw. Do not attempt to adjust beyond the stops as damage can occur. • Slowly turn the screw counterclockwise until the speed increases and then begins to drop. • Adjust the screw to the midpoint between the two positions. • Check the acceleration by following the steps outlined under ACCELERATION CHECK. The trimmer head must not turn at idle speed. 16 High Speed Adjustment "H" CAUTION: Do not operate engine at full speed for prolonged periods while making mixture adjustments as damage to the engine can occur. When making carburetor adjustments, do not force plastic limiter caps beyond stops or damage will occur. • Support lower end of the unit so that it is off the ground and will not make contact with any objects. Be sure the trimmer line is extended to maximum length allowed by the line limiter. • Start the engine and allow to idle. • Squeeze the throttle trigger fully. • Keep unit running at full speed; turn screw "H" very slowly clockwise until the speed begins to slow down. • Do not let go of the throttle trigger, and turn screw counterclockwise until the engine begins to run roughly. • Still holding the throttle trigger, turn the screw slowly a small amount until Prepare unit for storage at end of season or if it will not be used for 30 days or more.
