Line Head Line Replacement
The aluminum fixed
line
head uses either
2.5
mm (.105')
or 3.3 mm (.130") line. Because of the added load put on
the engine when using the thicker line, be sure to cut the
line to the proper length:
1.
To
replace the trimmer line, first cut the line to the
proper length mentioned above.
2.
Mark the center of the line with a felt tipped marker.
3. Thread the line through the cutter head guides as
shown in Figure 150. Make sure that the centerline
mark lines up on the cutter head shaft.

IMPORTANT While
it
is
possible to use two
lines with the metal fixed line head, best cutting
results are obtained by using only one line.

Line Head Removal
1. Remove the existing cutter line from the spool.
2.
Remove the cotter pin from the cutter head shaft.
3. Insert a flat bladed screwdriver into the slot in the
top of the shield to prevent the cutter head from
rotating during spool removal. Remove the nut by
turning
clockwise
(as viewed from the bottom of
the spool). See Figure 151.

Remove the spool being careful not to lose the
insert.
5.
Inspect the spool for damage. Pay particular
attention to the area where the line exits the spool.
Burrs in this area can lead to premature line
breakage at the point where
it
exits the spool.
See
Figure 152.
