(28).
u Wind the cutting line onto the spool in the direction of the
arrow. Make sure to wind the line on neatly and in layers.
Do not criss-cross (fig. O).
u When the wound cutting line reaches the recesses (29),
cut the line. Let the line protrude approx. 11 cm from the
spool and hold a finger on the line to keep it in place (fig.

u Proceed as described above to fit the spool on the tool.
Warning! Only use the appropriate type of Black & Decker
cutting line.
u Keep the tool away from hard objects and delicate plants.
Troubleshooting
u Cutting line will wear faster and require more feeding if
the cutting is done along pavements or other abrasive
surfaces or heavier weeds are being cut.
If your tool seems not to operate properly, follow the instruc-
tions below. If this does not solve the problem, please contact
your local Black & Decker repair agent.
u If the tool starts running slowly, reduce the load.
Warning! Before proceeding, remove the battery from the
Edging
tool.
Optimum cutting results are achieved on edges deeper than
50 mm.
Appliance runs slowly
u Check that the spool housing can rotate freely. Carefully
clean it if necessary.
u Check that the cutting line does not protrude more than
11 cm from the spool housing. If it does, cut it off so that it
just reaches the line trimming blade.
u Do not use the tool to create edges. To create edges, use
an edging spade.
u Guide the tool on its wheel (10) or edge guide (11) as
shown in fig. K.
u To make a closer cut, slightly tilt the tool.
Fitting a new spool of cutting line (fig. L)
Replacement spools of cutting line are available from your

the eyelet (24). The line should protrude approx. 11 cm
from the spool Housing.
Automatic line feed does not work
u Keep the tabs depressed and remove the spool cover
from the housing.
u Pull the cutting line until it protrudes 11 cm from the hous-
ing. If insufficient cutting line is left on the spool, install a
new spool of cutting line as instructed above.
u Align the tabs on the spool cover with the cut outs in the
housing.
u Push the cover onto the housing until it snaps securely
into place.
