Single Line Installation
Go To Step 8 for SplitLine™ Installation
6. Take approximately 18 feet (5.4 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. 19). 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. 20). Wind the line in
the direction indicated on the inner reel. Place your index finger between
the two lines to stop the lines from over-lapping. Do not overlap the ends
of the line. Proceed to step 11.
SplitLine™ Installation
8. Take approximately 9 feet (3 m) of new trimming line. Insert one end of
the line through one of the two holes in the inner reel (Fig. 21). 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. 21).
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 head to operate incorrectly.
12. Insert the ends of the line into the two holding slots (Fig. 22).
