Indexing Teeth
Winding Single Line
1. Cut one 12-foot (3.7 m) length of new single trimming line. Fold
the line in half to create a loop in the middle.
2. Insert the loop into the slot in the split wall (Fig. 20). Wind the
line tightly in the direction shown on the bottom of the inner reel
until about 6 inches (150 mm) of line remains.
• TB22: Wind the line counterclockwise
• TB252S: Wind the line clockwise
Keep the top half of the line above the split wall and the bottom
half of the line below the split wall.
3. Insert the two 6-inch ends into the two .095 holding slots (Fig. 22).
NOTE: Failure to wind the line in the direction indicated will cause
the cutting head to operate incorrectly.
Proceed to Part 3 - Installing the Inner Reel.
Winding Split Line
1. Cut one 6-foot (1.8 m) length of new split line trimming line. Split
each end about 6 inches (150 mm).
2. Using one split end, insert one line into the top hole and the
other line into the bottom hole in the inner reel (Fig. 21).
3. Wind the line tightly in the direction shown on the bottom of the
inner reel.
• TB22: Wind the line counterclockwise
• TB252S: Wind the line clockwise
The split wall will automatically divide the line. Wind the line until it
is completely divided and about 6 inches (150 mm) of line remains.
NOTE: Failure to wind the line in the direction indicated will cause
the cutting head to operate incorrectly.
4. Insert the two 6-inch ends into the two .095 holding slots (Fig. 22).
