Note: The metal shaft and housing will only rotate in
one direction.
To return to the trimming position, loosen the lock collar
and rotate the lower housing back 180° and retightening
the collar.
Edging (Fig. L)
Optimum cutting results are achieved on edges deeper than
50 mm. Do not use this trimmer to create trenches.
Using the edging wheel (7), or the wire guard, guide the
trimmer as shown in Fig. L.
Position the edging wheel on the edge of the pavement
or abrasive surface so the cutting line is over the grass or
dirt area to be edged.
Note: The Auto Feed System may not operate correctly if
wheeled edge guide is not used.
Note: You will experience faster than normal cutting line wear
if the edging wheel is positioned too far from the edge with the
cutting line positioned over the pavement or
abrasive surface.
To make a closer cut, slightly tilt the trimmer.
Return to the trimming postion by loosening the lock collar
and rotating the lower housing back 180°. The tool will
lock in the trimmer position.
Cutting Line / Line Feeding
Your trimmer uses 1.65 mm diameter, ROUND nylon line. During
use, the tips of the nylon lines will become frayed and worn and
the special self feeding spool will automatically feed and trim a
fresh length of line. Cutting line will wear faster and require more
feeding if the cutting or edging is done along pavements or other
abrasive surfaces or heavier weeds are being cut. The advanced
automatic line feeding mechanism senses when more cutting line
is needed and feeds and trims the correct length of line whenever
it's required. Do not bump trimmer on ground in attempt to feed
line or for any other purposes.
Helpful Cutting Tips
Use the tip of the string to do the cutting; do not force
string head into uncut grass.
Wire and fences cause extra string wear, even breakage.
Stone and brick walls, curbs, and wood may wear string
rapidly.
Do not allow spool cap to drag on ground or other surfaces.
In long growth, cut from the top down and do not exceed
300 mm high.
Keep trimmer tilted toward the area being cut; this is the
best cutting area.
The trimmer cuts when passing the unit from the left to
right. This will avoid throwing debris at the operator.
Avoid trees and shrubs. Tree bark, wood moldings, siding,
and fence posts can easily be damaged by the string.
(Original instructions)
Replacing the spool (Fig. M, N, O, P)
Warning! To reduce the risk of serious personal injury, turn
unit off and disconnect it from power source before making
any adjustments or removing/installing attachments or
accessories. An accidental start-up can cause injury
Depress the tabs (15) and remove the spool cap (25) from
the spool housing (16) in the trimmer head (Fig. M).
For best results, replace spool with BLACK+DECKER
model no. A6481.
Grasp empty spool with one hand and spool housing with
other hand and pull spool out.
If lever (17) (Fig. N) in base of housing becomes
dislodged, replace in correct position before inserting new
spool into housing.
Remove any dirt and grass from the spool and housing.
Unfasten the end of the cutting line and guide the line
into the eyelet (19) Fig. O.
Take the new spool and push it onto the boss (18) in the
housing (Fig. N). Rotate the spool slightly until it is
seated. The line should protrude approximately 136mm
from the housing.
Align the tabs on the spool cap with the slots (20) in the
housing (Fig. P).
Push the cap onto the housing until it snaps securely into
place.
Warning! To avoid trimmer damage, if the cutting line
protrudes beyond the trimming blade, cut it off so that it just
reaches the blade.
Rewinding spool from bulk line (Fig. Q, R, S)
Replacement spools of cutting line are available from your
BLACK+DECKER dealer. Packs containing 3
spools of cutting line are also available.
Unplug the tool.
Remove the empty spool from the trimmer as described
in "REPLACING THE SPOOL".
Remove any remaining cutting line from the spool.
Make a fold at the end of the cutting line at about 19mm
(21). Feed the cutting line into one of the line anchoring
slots (22) as shown in Fig. Q.
Note: Take care not to allow the the line on the spool to
unravel. Hold it firmly with one hand at all times.
Insert the 19mm end of the bulk line into the hole (23) in the
spool adjacent to the slot as shown in Fig. R. Make sure the
line is pulled tight against the spool as shown in Fig. S.
Wind the cutting line onto the spool in the direction of the
arrow on the spool. Make sure to wind the line on neatly
and in layers. Do not crisscross (Fig. S).
When the wound cutting line reaches the recesses (24),
cut the line. (Fig. R).
Fit the spool onto the trimmer as described in
"REPLACING THE SPOOL.
