Black & Decker BESTA525 Manuel D'utilisation page 10

ENGLISH
Maintain a cutting angle of 5° to 10° as shown in Fig. J.

Do not exceed 10° (Fig. J). Cut with the tip of the line.
To keep distance from hard surfaces use edge wheel (7).
Maintain a minimum distance of 600mm) between the

guard and your feet as shown in Fig. I. To acheive this
distance adjust the overall height of the trimmer as shown
in Fig. F.
Convert to edging mode (Fig. K)
The trimmer can be used in trimming mode or edging mode to
trim overhanging grass along lawn edges and flower beds.
Warning! Disconnect the plug from the power source before
making any adjustments.
Warning! When being used as an Edger, stones, pieces of
metal and other objects can be thrown out at high speed by
the line. The trimmer and guard are designed to reduce the
danger. However, MAKE SURE that other persons and pets
are at least 30m away.
To operate as a maintenance edger, turn the collar ( 5 ) as

shown in Fig. K.
Hold the metal shaft and rotate the lower housing 180°

as shown in Fig. K.
Turn the collar back until tight.

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
10
(Original instructions)
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.
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.
