Maintenance - Black & Decker STC1820EPC Original Instructions Manual

ENGLISH (Original instructions)
Convert to edging mode (Fig. L, M)
Warning! The wheeled edge guide should only be used when
in the edging mode.
The trimmer can be used in trimming mode or edging mode to
trim overhanging grass along lawn edges and flower beds. For
edging, the trimmer head should be in the position shown in
Figure M. If it is not:
Remove the battery from the trimmer.
u
Grasp the flip-to-edge collar (7) and push down as
u
shown in part 1 of Figure L.
Rotate the flip-to-edge collar 180° counterclockwise as
u
shown in part 2, until the handle snaps back into the
upper half of the trimmer.
To return to trimming position, pull the flip-to-edge collar
u
down and rotate the head clockwise back to its original
position.
Note: You will experience faster than normal cutting line wear
if the trimmer line is positioned directly over the sidewalk or
abrasive surface.
Edging (Fig. M)
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 30 m away. Optimum cutting results are achieved
on edges deeper than 50 mm.
Do not use this trimmer to create trenches.
u
Using the edging wheel (9), guide the trimmer as shown in
u
Figure M.
Position the edging wheel on the edge of the sidewalk or
u
abrasive surface so the cutting line is over the grass or dirt
area to be edged.
To make a closer cut, slightly tilt the trimmer.
u
Speed control & runtime extension mode (Fig. N)
This string trimmer gives you the choice to operate at a
more efficient speed to extend the runtime for larger jobs, or
accelerate the trimmer speed for high-performance cutting
(Figure N).
To extend runtime, pull the speed-control switch back
u
toward the battery (12) into position #1. This mode is best
for larger projects that require more time to complete.
To accelerate the trimmer, push the speed-control switch
u
forward toward the trimmer head (8) into position #2.
This mode is best to cut through heavier growth and for
applications that need higher RPM.
Note: When in acceleration mode (#2), runtime will be
decreased as compared to when trimmer is in extended
runtime mode (#1).

Helpful cutting tips
Use the tip of the string to do the cutting; do not force
u
string head into uncut grass. Use edge guide along
such things as fences, houses and flower beds for best
practices.
Wire and picket fences cause extra string wear, even
u
breakage. Stone and brick walls, curbs, and wood may
wear string rapidly.
Do not allow spool cap to drag on ground or other
u
surfaces.
In long growth cut from the top down and do not exceed
u
300 mm high.
Keep trimmer tilted toward the area being cut; this is the
u
best cutting area.
The trimmer cuts when passing the unit from the right to
u
left. This will avoid throwing debris at the operator.
Avoid trees and shrubs. Tree bark, wood moldings, siding,
u
and fence posts can easily be damaged by the string.
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
sidewalks 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 unit on ground in attempt to feed line or for any other
purposes.
Clearing jams and tangled line (Figures O, P, Q)
Warning! Remove the battery from the trimmer before
making any assembly, adjustments or changing accessories.
Such preventive safety measures reduce the risk of starting
the appliance accidentally. From time to time, especially
when cutting thick or stalky weeds, the line feeding hub may
become clogged with sap or other material and the line will
become jammed as a result. To clear the jam, follow the steps
listed below.
Remove the battery from the trimmer.
u
Press the release tabs (23) on the line spool cap (24),
u
as shown in Figure O and remove the cap by pulling it
straight off.
Pull the nylon line spool out and clear any broken line or
u
cutting debris from the spool area.
Place spool and line into spool cap with line "parked" in
u
slots provided as shown in Figure P1.
Insert the line end through the appropriate hole in the
u
spool housing. Pull slack line through until it pulls out of
the holding slots as shown in Figure P2.
Press the spool down gently and rotate it until you feel it
u
drop into place and then push to snap 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
u
the spool.
Align the spool cap tabs with the slots on the spool
u
housing.
Snap the spool cap back on as shown in Figure Q by
u
depressing lugs and pressing into spool housing.
Note: Make sure that cover is fully positioned, listen for two
audible clicks to ensure both lugs are correctly located. Power
the appliance on. In a few seconds or less you'll hear the
nylon line being cut automatically to the proper length.
Warning! To avoid appliance damage, if the cutting line
protrudes beyond the trimming blade, cut it off so that it just
reaches the blade.
Note: Other replacement parts (guards, spool caps, etc.) are
available through BLACK+DECKER service centers. To find
your local service location visit www.blackanddecker.com.
Warning! The use of any accessory not recommended by
BLACK+DECKER for use with this appliance could be
hazardous.
Replacing the spool (Fig. O, P, Q, R)
Remove battery from appliance.
u
Depress the tabs (23) and remove the spool cap (24) from
u
the spool housing (11) (Figure O).
Grasp empty spool with one hand and spool housing with
u
other hand and pull spool out.
If lever (25) or spring (26) in base of housing (Figure R)
u
becomes dislodged, replace in correct position before
inserting new spool into housing.
Remove any dirt and grass from the spool and housing.
u
Unfasten the end of the cutting line and guide the line into
u
the eyelet (P2) Figure P.
Take the new spool and push it onto the boss (27)
u
(Figure R) in the housing. Rotate the spool slightly until it
is seated. The line should protrude approximately 136 mm
from the housing.
Align the tabs on the spool cap with the slots in the
u
housing (Figure Q).
Push the cap onto the housing until it snaps securely into
u
place.
Rewinding spool from bulk line (Fig. S, T, U)
Bulk line is also available for purchase from your local retailer.
Note: Hand wound spools from bulk line are likely to become
tangled more frequently than BLACK+DECKER factory
wound spools. For best results, factory wound spools are
recommended. To install bulk line, follow the steps below:
Remove battery from appliance.
u
(Original instructions) ENGLISH
Remove the empty spool from the appliance as described
u
in "Replacing the spool."
Remove any remaining cutting line from the spool.
u
Make a fold at the end of the cutting line at about 19 mm
u
(28). Feed the cutting line into one of the line anchoring
slots (29) as shown in Figure S.
Insert the 19 mm end of the bulk line into the hole (30) in
u
the spool adjacent to the slot as shown in Figure T. Make
sure the line is pulled tight against the spool as shown in
Figure T.
Wind the cutting line onto the spool in the direction of the
u
arrow on the spool. Make sure to wind the line on neatly
and in layers. Do not crisscross (Figure U).
When the wound cutting line reaches the recesses (31),
u
cut the line (Figure T).
Fit the spool onto the appliance as described in "Replacing
u
the spool".
