4. Insert the line end through the eyelet in the spool hub, as shown
in figure 19. Pull the line through the hole to maintain tension

OPTION 1: ACCESSORY REPLACEMENT SPOOL
Use Black & Decker replacement spool Model No. AF-100. Discard
old spool.
OPTION 2: REWINDING SPOOL USING BULK LINE
Bulk line for your trimmer/edger is available at extra cost from your
local dealer or Black & Decker Service Center. To install bulk line,
follow the steps below. (Use .065 in. diameter ROUND
line only)
1. Insert one end of the bulk line
into the hole in the spool as
shown in figure 21 about
1/2 in. (12 mm).
2. Hold the line in the hole and
pull the rest of the line through
the slot in the spool.
3. Snugly and evenly wind the
bulk line onto the spool in the
direction of the arrow on the
spool until the line builds up to
the notches in the spool rim.
Do not overfill spool. The spool holds 30 feet (10 m) of line.
3. Unwrap about one foot (30 cm)
of line to ensure that itʼs
undamaged. If it is OK rewind it
and insert the line end through
the eyelet in the spool hub as
shown in figure 19. Pull
4 in. (10 cm) of the line through
the hole and maintain tension
while placing the spool down
into the hub with the arrow up,
as shown in figure 20.
4. Press the spool down GENTLY
and rotate it until you feel it drop
into place. (When in place, the
spool will turn a few degrees left
and right freely). Take care to
keep the line from becoming
trapped under the spool.
5. Snap the hub cap back on, and
power the tool on. In a few
seconds or less youʼll hear the
nylon line being cut
automatically to the proper length.
