LINE INSTALLATION
This section covers both Membrane line and standard
single line installation.
Always use manufacturer’s 0.105 inch (2.67 mm)
replacement line. Line other than specified may make
the engine overheat or fail.
Never use metal-reinforced line, wire, chain, or
rope, etc. These can break off and become a
dangerous projectile.
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 clockwise (Fig. 6-1). Inspect the
bolt inside the Bump Knob to make sure it moves
freely. Replace the Bump Knob if damaged.
2. Remove the inner reel from the outer spool
(Fig. 6-1).
3. Remove spring from the inner reel (Fig. 6-1).
4. Use a clean cloth to clean the the inner reel, spring,
shaft, and inner surface of the outer spool.
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.
Single Line Installation
Go To Step 8 for Membrane Line Installation
6. Take approximately 30 feet (9.1 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. 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.
