Always use Genuine Factory Parts™ 0.095 in. (2.41 mm) replacement line. Line other than the specified may make the engine overheat or fail. WARNING: Never use metal-reinforced line, wire, chain or rope. These can break off and become dangerous projectiles. There are two methods to replace the trimming line: • Wind the inner reel with new line • Install a prewound inner reel Winding the Existing Inner Reel 1. Hold the outer spool with one hand and unscrew the Bump Knob clockwise (Fig. 31). Inspect the bolt inside the bump knob to make sure it moves freely. Replace the bump knob if damaged. 2. Remove the inner reel from the outer spool (Fig. 31). 3. Remove spring from the inner reel (Fig. 31). 4. Use a clean cloth to clean the the inner reel, spring, shaft and inner surface of the outer spool (Fig. 32). 5. Check the indexing teeth on the inner reel and outer spool for wear (Fig. 33). If necessary, remove burrs or replace the reel and spool.

Single line can be used on either type of inner reel. Use Figure 35 to identify the inner reel you have. NOTE: Always use the correct line length when installing trimming line on the unit. The line may not release properly if the line is too long. Fig. 35 Loop Single Line Installation Go To Step 8 for SplitLine™ Installation 6. Take approximately 40 feet (12.2 m) of new trimming line, loop it into two equal lengths. Insert each end of the line through one of the two holes in the inner reel (Fig. 35). Pull the line through the inner reel so that the loop is as small as possible. 7. Wind the lines in tight even layers, onto the reel (Fig. 36). Wind the line in the direction indicated on the inner reel. Place your index finger between the two lines to stop the lines from overlapping. Do not overlap the ends of the line. Proceed to step 11. Fig. 36 SplitLine™ Installation 8. Take approximately 20 feet (6.1 m) of new trimming line. Insert one end of the line through one of the two holes in the inner reel (Fig. 37). Pull the line through the inner reel until only about 4 inches is left out. 9. Insert the end of the line into the open hole in the inner reel and pull the line tight to make the loop as small as possible (Fig. 37). 10. Before winding, split the line back about 6 inches. 11. Wind the line in tight even layers in the direction indicated on the inner reel. NOTE: Failure to wind the line in the direction indicated will cause the cutting attachment to operate incorrectly. Loop Fig. 37 12. Insert the ends of the line into the two holding slots (Fig. 38). 13. Insert the ends of the line through the eyelets in the outer spool and place inner reel with spring inside the outer spool (Fig. 39). Push the inner reel and outer spool together. While holding the inner reel and outer spool, grasp the ends and pull firmly to release the line from the holding slots in the reel. Holding Slots Fig. 38 NOTE: The spring must be assembled on the inner reel before reassembling the cutting attachment. 14. Hold the inner reel in place and install the bump knob by turning counterclockwise. Tighten securely. Spring Fig. 39 19 6. If the level is low, add a small amount of oil to the oil fill hole and recheck (Fig. 41). Repeat until the oil level reaches the top of the dipstick. NOTE: Do not overfill the unit. Fig. 41 NOTE: Make sure the O-ring is in place on the oil fill plug/dipstick when checking and changing the oil (Fig. 41).
