5.Check the indexing teeth on the inner reel and outer spool for wear (Fig. 6-2). If necessary, remove burrs or replace the reel and spool.

NOTE: Membrane line can only be used with the inner reel with the slotted holes. Single line can be used on either type of inner reel. Use figure 6-3 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.

6.Take approximately 40 feet (12.2 m) of new trim- ming line, loop it into two equal lengths. Insert each end of the line through one of the two holes in the inner reel (Fig. 6-4). 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. 6-5). 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.

Membrane Line 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. 6-6). 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. 6-6).

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 indi- cated will cause the cutting attachment to operate incorrectly.

12.Insert the ends of the line into the two holding slots (Fig. 6-7).

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. 6-8). 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.

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.
