Assembly Installing Trimmer Head Shield POTENTIAL HAZARD • Foreign objects can be thrown by Trimmer. POTENTIAL HAZARD • The cutoff blade is sharp. WHAT CAN HAPPEN • Contact with cutoff blade could cause serious cuts or personal injury. HOW TO AVOID THE HAZARD • Keep hands, feet and clothing away from cutoff blade. 1. Fasten the string cutoff blade to the trimmer head shield with two M5 x 25 screws, lock washers and hex nuts as shown (Fig 5).
Installing Trimmer Head Before Operation IMPORTANT: Make sure the trimmer head is for LEFT-HAND ROTATION (counterclockwise) as viewed from the operator’s position, and that the trimmer head adapter is a male, M8 x 1.25 left-hand thread. Oil and Fuel 1. Thread the trimmer head into the gearcase, tighten trimmer head firmly by hand (Fig. 6). 1 2 Figure 6 1. Gearcase 2. Trimmer Head POTENTIAL HAZARD • If the trimmer head is not adequately tightened, it can come loose from the Trimmer during use.
4. Always open the fuel tank cap slowly to release any possible overpressure inside the tank. 5. Do not overfill the fuel tank. Stop filling 1/4–1/2 inch (6mm–13mm) from the top of the tank. 6. Tighten the tank fuel cap carefully but firmly after refilling. 7. Wipe up any spilled fuel before starting the engine. 8. Move the String Trimmer at least 10 feet (3 m) away from the fueling location and fuel storage container before starting the engine (Fig. 2).

Hot Restart To start an engine that is already warmed up (hot restart), or if the ambient temperature exceeds 68 F (20 C): 1. Pump the primer bulb at the bottom of the carburetor until fuel can be seen flowing through the fuel return line to the fuel tank (Figs. 7 and 8). 2. Move the choke lever to the open ( ) position and move the stop switch to the “ON” position (Figs. 9 and 10). 3. Leave the throttle trigger in the idle position and pull the starter handle (Figs. 9 and 10). 4.
• Always wear gloves and protective clothing when operating the String Trimmer. • If the trimmer head becomes jammed, stop the engine immediately. • Make certain all moving parts have stopped and disconnect the spark plug before inspecting the equipment for damage. • Never use a String Trimmer that has chipped, cracked or broken trimmer head. m-2980 Figure 13 Cutting with Nylon Trimmer Line • The tip of the line does the cutting. The line should stay extended while cutting (Fig. 12).
Rewinding the Trimmer Spool Scaling To remove unwanted vegetation, hold the trimmer head about 3 in. (7.6 cm) above the ground and at an angle. Allow the tip of the line to strike the ground cutting the vegetation off at the surface (Fig. 15). POTENTIAL HAZARD • Use of improper line could cause line to break and be thrown in operator’s or bystander’s direction. WHAT CAN HAPPEN • Use of improper line could result in serious personal injury.

Clean the dirt from the inside of the spool parts if required. 4. Cut two (2) new lines (10’–15’) of equal length. 5. Place ends of line in holes on inside of spool (Figs. 19). 6. Place the two (2) lines through the slits and wind the line in even, tight layers onto the spool in the direction indicated on the spool (Figs. 19).

IMPORTANT: The air filter screen is designed to fit into the air filter cover ONE WAY ONLY. Make sure the cutouts in the screen fit onto the matching plastic posts in the air filter cover. The fit should be snug (Fig. 25). 5. While still holding on to the fuel hose, attach the new fuel filter. 6. Drop the new fuel filter back into the fuel tank. 7. Make sure that the fuel filter is not stuck in a corner of the tank, and that the fuel hose is not doubled over (kinked) before refueling.
When the throttle trigger is released, the engine should return to an idle speed between 2400 and 2800 RPM, or just below the clutch engagement speed. The trimmer head must not rotate and the engine should not stall (stop running) at engine idle speed (Fig. 27). m-2974 Figure 28 1. Idle Speed Adjustment Screw Maintenance Interval • The spark plug should be removed from the engine and checked after each 25 hours of operation.
3. Twist the high tension lead boot on the spark plug back and forth a couple of times to loosen the boot, then pull the boot off of the spark plug. 4. Remove the spark plug. 5. Clean the electrodes with a stiff brush (Fig. 32). 6. Adjust the electrode air gap to .024–.028 in. (0.6–0.7mm) (Fig. 32). m-2997 7. Replace the spark plug if it is oil-fouled, damaged, or if the electrodes are worn down. 8. Do not overtighten the spark plug when installing. The tightening torque is 95–148 in. lbs. (10.
Cylinder Cooling Fins Maintenance Interval The cylinder cooling fins should be cleaned after every 25 hours of operation, or once a week, whichever comes first. Air must flow freely around and through the cylinder cooling fins to prevent engine overheating. Leaves, grass, dirt and debris buildup on the fins will increase the operating temperature of the engine, which can reduce engine performance and shorten engine life. Cooling Fin Cleaning Figure 33 Model 53010 & 53011 1.
Spark Arrester Maintenance Model 53010 & 53011 1. With the engine at ambient (room) temperature, remove the socket head screw holding the muffler cover, then remove the muffler cover (Fig. 30). 2. Remove the four socket head screws holding the spark arrester assembly to the muffler (Fig. 34). 3. Remove and clean the tail, screen, gasket and plate with a safety solvent and a stiff brush. If any part cannot be thoroughly cleaned, it must be replaced. 4.
Gearcase Maintenance 5. Remove the spark plug and squirt a very small amount of oil into the cylinder (Fig. 36). The gearcase is a sealed unit which has been greased at the factory. No gearcase maintenance or lubrication is required or recommended. General Cleaning and Tightening POTENTIAL HAZARD • When engine is running, cutting head is rotating and other parts are moving. WHAT CAN HAPPEN • Contact with rotating cutting head or other moving parts could cause serious personal injury or death.
