This section covers both SplitLine™ and standard single
line installation.
Always use original equipment manufacturer replacement
line. Use 0.095 in. (2.41 mm) line for the BL26BC, and
0.080 in. (2.03 mm) line for the BL26C0. Line other than
the specified may make the engine overheat or fail.
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. For the BL26BC, unscrew it clockwise
(Fig. 31). For the BL26C0, unscrew the Bump Knob
counterclockwise (Fig. 32).
Inspect the bolt inside the bump knob to make sure it
moves freely. Replace the bump knob if damaged.

LINE INSTALLATION
Your trimmer is equipped with one of two cutting
attachments. The BL26C0 & BL26BC use a bump head,
while the BL26SS is equipped with a SpeedSpool
cutting head. Refer only to the section that applies to
the type of cutting attachment your unit is equipped
with.
BUMP HEAD (BL26C0 & BL26BC)
Never use metal-
reinforced line, wire,
chain or rope. These can break off and
become dangerous projectiles.
