INSTALLING FIXED LINE
Always use 17.5 inches of precut .105”
TrimmerPlus
®
spiral line or 17.5 inches
of .110” trimming line. Lines other than
these may make the unit overheat or
fail.
To install the trimming line:
1. Insert each end of the replace-
ment line into the holes on either
side of retention hook (Fig. 5).
2. Push the ends through until
they stick out of the sides of the
head (Fig. 6).
3. Pull the ends through making
sure that the ends are of equal
length and the middle of the line
is centered between the insertion
holes (Fig. 7).
4. If the ends are not of equal
length, push the longer end back
through the head part way and
pull the shorter end to
compensate. Repeat until both
ends are the same length.
5. Push the trimmer line behind the
hook to secure it from coming
loose while running (Fig. 8).
