4. Hold the housing securely, then continue to rotate the spool in the
direction of the arrow an additional 1/4 inch or the width of the
channel to unlock the spool from the housing.
5. Lift the spool out of the housing and remove any remaining line
from the spool.
6. Measure approximately 20 feet (6 meters) of new line, then thread
one end through the hole in the ridge on the spool.
Pull the line until the two lengths are equal.
7. 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 line to get twisted.
It is important to prevent the two
lines from getting twisting over
each other. Position a finger
between the lines as you turn the
spool to prevent the lines from
twisting.
8. 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.
9. Feed both line ends
through the metal eyelets
in the housing.
It may be necessary to push down and rotate the outer drive until
the round lugs align with the metal eyelets.
10.Align the channels in the spool with the round lugs on the outer
drive. With the channels and notches aligned with the metal
eyelets, slide the spool into the housing with a continuous snap-in
motion. 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 if 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 your hear
it snap out of the notch.
11.Hold the housing and rotate the spool in the direction of the arrow
to lock the round lug into the half-round locking hole. Trim the lines
so they are equal length.
Removal and Installation
This section shows you how to remove and install either style trimmer
head from your trimmer.
1. Insert the tip of a 4 mm hex wrench, or equivalent, fully into the
gear case hole.
2. Turn the trimmer cutting-line head until you feel the tool drop into
the hole in the cover plate/spacer A. Verify the trimmer head does
not turn.
3. All output shafts use left-hand threads. Make sure the tool remains
in the hole, then grasp the trimmer head and turn in the direction of
the arrow to remove.
4. Remove spacer B and cover plate/spacer A from the output shaft
). Note the order and orientation of each part as you
remove them.
5. Installation is the reverse of removal. Always clean debris, dirt,
loose line, etc. from the trimmer head and output shaft area before
installation. Tighten the trimmer head securely.
