SERVICING YOUR HONDA TRIMMER
Manual Cutting-Line Head
1. Clean any mud, dirt, debris, etc. from the area around the trimmer head; otherwise, it will make it
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.
