OPERATING INSTRUCTIONS ADJUSTING TRIMMING LINE LENGTH DECORATIVE TRIMMING Your unit is equipped with a cutting head that allows the operator to release more trimming line without stopping the engine. To release additional line, lightly tap the cutting head on the ground (Fig. 11) while operating the unit at high speed. Decorative trimming is accomplished by removing all vegetation around trees, posts, fences, etc. Rotate the entire unit so that the cutting head is at a 30° angle to the ground (Fig. 12).
MAINTENANCE AND REPAIR INSTRUCTIONS LINE INSTALLATION FOR THE SPEEDSPOOL® The trimming line in the speed spool may be replaced by two different methods. • Winding the existing inner reel with new line • Installing a prewound inner reel TO INSTALL NEW TRIMMING LINE, IT IS NOT NECESSARY TO REMOVE THE BUMP KNOB. 2. Insert 10 feet (2.5 m) of .080 in (2.03 mm) trimming line into one of the two eyelets and push it up through the line loading hole in the inner reel (Fig. 14).
MAINTENANCE AND REPAIR INSTRUCTIONS 5. Repeat the procedure with the second eyelet and use the same amount of line as specified in Step 2. 6. Wind the inner reel counterclockwise until approximately four (4) inches of line remains outside of the eyelets in the outer spool (Fig. 17). 1. If you need to remove the Bump Knob to clean the spool or remove jammed, excess line, hold the outer spool, and unscrew the Bump Knob counterclockwise (Fig. 19).
MAINTENANCE AND REPAIR INSTRUCTIONS NOTE: The inner reel must be completely dry before reinstalling it into the outer spool. Do not lubricate the inner reel or outer spool assembly. 4. Clean the shaft and the inner surface of the outer spool. To clean the shaft underneath the plunger, press down on the plunger (Fig. 22). Remove any dirt and/or debris from the shaft.

MAINTENANCE AND REPAIR INSTRUCTIONS 4. Apply enough clean motor oil to lightly coat the filter (Fig. 27). Fig. 27 The condition of the air filter is important to the operation of the unit. A dirty air filter will restrict the air flow, which upsets the fuel-air mixture in the carburetor. The resulting symptoms are often mistaken for an out-of-adjustment carburetor. Therefore, check the condition of the air filter before adjusting the carburetor. Refer to Air Filter Maintenance.
MAINTENANCE AND REPAIR INSTRUCTIONS REPLACING THE SPARK PLUG STORAGE Use a Champion RCJ-6Y spark plug (or equivalent). Correct air gap is 0.025 in. (0.655 mm). Remove plug after every 50 hours of operation and check its condition. 1. Stop the engine and allow it to cool. Pull the wire off of the spark plug. If the unit will be stored for an extended period of time, use the following storage procedure. 1. Drain all fuel from the fuel tank and drain into a container with the same 2-cycle fuel mixture.
