Installing Replacement Nylon Line
First, determine which cutting-line head style is on your trimmer. A
manual-feed trimmer head has a three-sided knob on the bottom of
the head, while the semi-matic head has a spring-loaded round button
on the bottom of the head.
Do not use any kind of metal, wire, or wire rope line on the trimmer.
Use only genuine Honda replacement nylon trimmer line or
equivalent.
Honda trimmers come standard with low noise line. Using non-Honda
line may result in increased noise levels.
For original, factory-installed Honda cutting-line heads, use only nylon
monofilament line in the line sizes shown below.

1. Clean any mud, dirt, debris, etc. from the area around the trimmer
head; otherwise, it will be more difficult to service.
2. Rotate the left-hand threaded knob in the direction of the arrow and
remove the knob.
Remove the spring and spool from the housing then remove any
remaining old line from the spool.

3. Measure approximately 20 feet (6 meters) of line, then thread one
end through the hole in the ridge on the spool. Pull the line until the
two line lengths are equal.

4. Wind both lines tightly and evenly from side-to-side ignoring the
ridge. Feed the line while turning the spool in the direction of the
arrow. Do not allow the lines to get twisted.
It is important to prevent the two lines from getting twisted over
each other. Position a finger between the lines as you turn the
spool to prevent the lines from twisting.
5. When you have about 6 inches (150 mm) of line remaining, press
the lines into the two notches on the bottom of the spool. This will
hold the lines on the spool for reassembly.
NOTCHES
6. Feed both line ends through the metal eyelets in the housing.
Be careful not to let the line slip under the spool. When the spool
reaches the bottom of the housing, the lines should snap out of the
spool notches.
If you are not sure the lines have snapped out of the notches,
gently pull the spool away from the housing about an 1/8 inch to
inspect the lines. If necessary, gently pull each line until you hear it
snap out of the notch. Trim the lines so they are equal length.
