REPLACING THE TRIMMING LINE
Only use the trimming line described in the Specifications section.
Other types of trimming line may cause the unit to overheat or fail.
WARNING:
Never use metal-reinforced line, wire, chain or
rope. These can break off and become dangerous projectiles.
NOTE: Always use the correct line length when installing trimming
line. The line may not release properly if the line is too long.
Part 1 - Removing the Inner Reel
1. Hold the cutting head in place (Fig. 27). Turn the bump knob
clockwise to unscrew it from the cutting head (Fig. 27).
NOTE: The outer spool (Fig. 28) will remain attached to the unit.
2. Inspect the bolt inside the bump knob to make sure it moves
freely (Fig. 27). Replace the bump knob if it is damaged.
3. Remove the inner reel from the outer spool (Fig. 28).
4. Remove the spring from the inner reel (Fig. 28).
5. Use a clean cloth to clean the inner reel, spring, arbor and inner
surface of the outer spool.
6. Check the indexing teeth and holding slots for wear (Fig. 29). If
necessary, remove burrs or replace the inner reel and outer spool.
Proceed to Part 2 - Winding New Trimming Line onto the Inner Reel.
Part 2 - Winding New Trimming Line onto the Inner Reel
• If using single line, refer to Winding Single Line.
• If using split line, refer to Winding Split Line.
• If using a prewound inner reel, proceed to Part 3 - Installing the
Inner Reel.
Winding Single Line
1. Cut one 18-foot (5.5 m) length of new single trimming line. Fold
the line in half to create a loop in the middle.
2. Insert the two line ends through the two holes in the inner reel (Fig.
30). Pull the line through the inner reel so that the loop is as small
as possible (Fig. 30). Make sure the line ends are of equal length.
3. Wind the line tightly in the direction shown on the bottom of the
inner reel until about 6 inches (150 mm) of line remains. Place
your index finger between the two lines to stop the lines from
overlapping.
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 holding slots (Fig. 31).
Proceed to Part 3 - Installing the Inner Reel.
Winding Split Line
1. Cut one 9-foot (2.7 m) length of new split line trimming line.
2. Insert one line end through one of the two holes in the inner reel.
Pull the line through the inner reel until about 4 inches (10 cm)
remain (Fig. 32).
3. Insert the end of the 4-inch section into the open hole in the
inner reel and pull the line tight to make the loop as small as
possible (Fig. 32).
4. Split the other line end about 6 inches (150 mm).
5. Wind the line tight in 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.
6. Insert the two 6-inch ends into the two holding slots (Fig. 31).
Proceed to Part 3 - Installing the Inner Reel.
