UNLESS they are properly protected from short circuits.
So when transporting individual battery packs, make
sure that the battery terminals are protected and well
insulated from materials that could contact them and
cause a shortcircuit.

The RBRC® Seal

The RBRC® (Rechargeable Battery
Recycling Corporation) Seal on the nickel
cadmium, nickel metal hydride or lithium­ion batteries (or battery packs) indicates
that the costs to recycle these batteries
(or battery packs) at the end of their useful life have already
been paid by BLACK+DECKER. In some areas, it is illegal
to place spent nickel cadmium, nickel metal hydride or
lithium-ion batteries in the trash or municipal solid waste
stream and the Call2Recycle® program provides an
environmentally consciousalternative.

Call 2 Recycle, Inc., in cooperation with BLACK+DECKER
and other battery users, has established the program in
the United States and Canada to facilitate the collection
of spent nickel cadmium, nickel metal hydride or
lithium-ion batteries. Help protect our environment and
conserve natural resources by returning the spent nickel
cadmium, nickel metal hydride or lithium-ion batteries to
an authorized BLACK+DECKER service center or to your
local retailer for recycling. You may also contact your local
recycling center for information on where to drop off the
spent battery. RBRC® is a registered trademark of Call 2

Important Safety Instructions for All
Battery Chargers



WARNING: Read all safety warnings

and all instructions for the battery pack, charger
and appliance. Failure to follow the warnings
and instructions may result in electric shock, fire
and/or seriousinjury.

• DO NOT attempt to charge the battery pack with
any chargers other than the ones in this manual.

The charger and battery pack are specifically designed to
worktogether.

• These chargers are not intended for any uses other

than charging BLACK+DECKER rechargeable
batteries. Any other uses may result in risk of fire, electric

shock orelectrocution.

• Do not expose the charger to rain orsnow.

• Pull by the plug rather than the cord when
disconnecting the charger. This will reduce the risk of
damage to the electric plug andcord.

• Make sure that the cord is located so that it will not

be stepped on, tripped over or otherwise subjected
to damage orstress.

• Do not use an extension cord unless it is absolutely
necessary. Use of improper extension cord could result in

risk of fire, electric shock orelectrocution.

• When operating a charger outdoors, always provide

a dry location and use an extension cord suitable
for outdoor use. Use of a cord suitable for outdoor use

reduces the risk of electricshock.

• An extension cord must have adequate wire size
(AWG or American Wire Gauge) for safety. The smaller
the gauge number of the wire, the greater the capacity
of the cable, that is, 16 gauge has more capacity than 18
gauge. An undersized cord will cause a drop in line voltage
resulting in loss of power and overheating. When using
more than one extension to make up the total length,
be sure each individual extension contains at least the
minimum wire size. The following table shows the correct
size to use depending on cord length and nameplate
ampere rating. If in doubt, use the next heavier gauge. The
lower the gauge number, the heavier thecord.

• Do not place any object on top of the charger or
place the charger on a soft surface that might block
the ventilation slots and result in excessive internal
heat. Place the charger in a position away from any heat

source. The charger is ventilated through slots in the top
and the bottom of thehousing.

• Do not operate the charger with a damaged cord

orplug.

• Do not operate the charger if it has received a sharp
blow, been dropped or otherwise damaged in any
way. Take it to an authorized servicecenter.

• Do not disassemble the charger; take it to an
authorized service center when service or repair
is required. Incorrect reassembly may result in a risk of

electric shock, electrocution orfire.

• Disconnect the charger from the outlet before

attempting any cleaning. This will reduce the risk of
electric shock. Removing the battery pack will not reduce

thisrisk.

• NEVER attempt to connect 2 chargerstogether.

• The charger is designed to operate on standard

120V household electrical power. Do not attempt to
use it on any other voltage. This does not apply to the

vehicularcharger.



WARNING: Burn hazard. Do not

submerge the battery pack in any liquid or allow any
liquid to enter the battery pack. Never attempt to open
the battery pack for any reason. If the plastic housing
of the battery pack breaks or cracks, return to a service
center forrecycling.



CAUTION: Burn hazard. To reduce the risk

of injury, charge only BLACK+DECKER rechargeable
battery packs. Other types of batteries may
overheat and burst resulting in personal injury and
propertydamage.

NOTICE: Under certain conditions, with the

charger plugged into the power supply, the charger
can be shorted by foreign material. Foreign materials
of a conductive nature, such as, but not limited to,
grinding dust, metal chips, steel wool, aluminum
foil or any buildup of metallic particles should be
kept away from the charger cavities. Always unplug
the charger from the power supply when there is no
battery pack in the cavity. Unplug the charger before
attempting toclean.

Charging a Battery

BLACK+DECKER chargers are designed to charge
BLACK+DECKER batterypacks.

NOTE: To ensure maximum performance and life of lithium
ion battery packs:

• Charge the battery pack fully before firstuse.

• Recharge discharged batteries as soon as possible
after everyuse.

• Do not discharge batteriesfully.

1. Plug the charger into an appropriate outlet before
inserting the batterypack.

2. Insert the battery pack into the charger.

3. The green LED will flash indicating that the battery is
beingcharged.

4. The completion of charge is indicated by the green LED
remaining on continuously. The pack is fully charged
and may be used at this time or left on thecharger.

Leaving the battery in the charger

The charger and battery pack can be left connected with
the green LED glowing indefinitely. The charger will keep
the battery pack fresh and fully charged.

Charger Cleaning Instructions



WARNING: Shock hazard. Disconnect

the charger from the AC outlet before cleaning. Dirt
and grease may be removed from the exterior of the
charger using a cloth or soft non-metallic brush. Do
not use water or any cleaningsolutions.

Important Charging Notes

1. Longest life and best performance can be obtained if
the battery pack is charged when the air temperature is
between 65°F and 75°F (18° – 24°C). DO NOT charge
the battery pack in an air temperature below +40°F
(+4.5°C), or above +104°F (+40°C). This is important
and will prevent serious damage to the batterypack.

2. The charger and battery pack may become warm to the
touch while charging. This is a normal condition, and
does not indicate a problem. To facilitate the cooling of
the battery pack after use, avoid placing the charger or
battery pack in a warm environment such as in a metal
shed or an uninsulatedtrailer.

3. If the battery pack does not charge properly:

a. Check operation of receptacle by plugging in a lamp

or other appliance;

b. Check to see if receptacle is connected to a light

switch which turns power off when you turn out the
lights;

c. Move the charger and battery pack to a location

where the surrounding air temperature is
approximately 65°F – 75°F (18° – 24°C);

d. If charging problems persist, take the battery pack

and charger to your local servicecenter.

4. The battery pack should be recharged when it fails to
produce sufficient power on jobs which were easily
done previously. DO NOT CONTINUE to use under these
conditions. Follow the charging procedure. You may
also charge a partially used pack whenever you desire
with no adverse effect on the batterypack.

5. Foreign materials of a conductive nature such as, but
not limited to, grinding dust, metal chips, steel wool,
aluminum foil, or any buildup of metallic particles
should be kept away from charger cavities. Always
unplug the charger from the power supply when there
is no battery pack in the cavity. Unplug the charger
before attempting toclean.

6. Do not freeze or immerse the charger in water or any
otherliquid.

Storage Recommendations

1. The best storage place is one that is cool and dry, away
from direct sunlight and excess heat orcold.

2. For long storage, it is recommended to store a fully
charged battery pack in a cool dry place out of the
charger for optimalresults.

NOTE: Battery packs should not be stored completely
depleted of charge. The battery pack will need to be
recharged beforeuse.

Operating the Trimmer (Fig. H)



WARNING: Keep the rotating string

roughly parallel with the ground (tilted no more than
30 degrees). This trimmer is not an edger. DO NOT
TILT the trimmer so that the string is spinning near
a right angle to the ground. Flying debris can cause
seriousinjury.

• With the unit on, angle unit and slowly swing the
trimmer side to side as shown in Fig.H.

• Maintain a cutting angle of 5° to 10° as shown in Fig. H1.
Do not exceed 10° (Fig. H2). Cut with the tip of the line.

• Maintain a minimum distance of 24 inches (609.6 mm)
between the guard and your feet as shown in Fig.H3.

Cutting Line / Line Feeding



CAUTION: Use only BLACK+DECKER

replacement spools and line. Using any other
manufacturer's line can reduce performance, damage
the trimmer or cause personalinjury. USE ONLY
.065inch (1.65 mm) DIAMETER ROUND NYLON LINE.
Do not use serrated or heavier gauge line, as they
will overload the motor and cause overheating. This
line is available at your local dealer or authorized
servicecenter.

Your trimmer uses .065 inch (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 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 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 picket 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 12 inches (304.8 mm)high.

• Keep trimmer tilted toward the area being cut; this is
the best cuttingmethod.

• The trimmer cuts when passing the unit from the left to
right. This will avoid throwing debris at theoperator.

ENGLISH

• Avoid trees and shrubs. Tree bark, wood moldings, siding,
and fence posts can easily be damaged by thestring.

MAINTENANCE



WARNING: To reduce the risk of

serious personal injury, turn unit off and remove
the battery pack before making any adjustments
or removing/installing attachments or
accessories. An accidental start-up can causeinjury.

1. Keep the air intake slots clean to avoidoverheating.

2. Your trimmer line can dry out over time. To keep your
line in top condition, store spare pre-wound spools or
bulk line in a plastic, sealable bag with a tablespoon
ofwater.

3. Plastic parts may be cleaned by using a mild soap and
a damprag.

4. The line cutter on the edge of the guard can dull over
time. It is recommended you periodically touch-up the
sharpness of the blade with afile.

Cleaning



WARNING: Blow dirt and dust out of all

air vents with clean, dry air at least once a week. To
minimize the risk of eye injury, always wear ANSI Z87.1
approved eye protection when performingthis.



WARNING: Never use solvents or other

harsh chemicals for cleaning the non-metallic parts
of the tool. These chemicals may weaken the plastic
materials used in these parts. Use a cloth dampened
only with water and mild soap. Never let any liquid
get inside the tool; never immerse any part of the tool
into aliquid.

Accessories



WARNING: Since accessories, other than

those offered by BLACK+DECKER, have not been tested
with this product, use of such accessories with this tool



WARNING: The use of any accessory not

recommended by BLACK+DECKER for use with this

Rewinding Spool From Bulk Line
(Fig. M–O)

(use only .065 in. ROUND diameter line)

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 pack fromtrimmer.

• 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
3/4inch (19mm)

27

. Feed the cutting line into one of

the line anchoring slots

28

as shown in Fig.M.

• Insert the 3/4 inch (19mm) end of the bulk line into
the hole

29

in the spool adjacent to the slot as shown
in Fig. N. Make sure the line is pulled tight against the
spool as shown in Fig.O.

• 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.O).

• When the wound cutting line reaches the recesses

30

,

cut the line. (Fig.N).

• Fit the spool onto the trimmer as described in
Replacing the Spool.

Troubleshooting

Trimmer Runs Slowly

1. Remove battery pack fromtrimmer.

2. Check that the spool housing can rotate freely. Carefully
clean it ifnecessary.

3. Check that the cutting line does not protrude more
than approximately 5-3/8 inches (136mm) from the
spool. If it does, cut it off so that it just reaches the line
trimmingblade.

Automatic Line Feed Does Not Work

1. Remove battery pack fromtrimmer.

2. Remove the spoolcap.

ENGLISH

11

3. Pull the cutting line until it protrudes approximately
5-3/8 inches (136mm) from the spool. If insufficient
cutting line is left on the spool, install a new spool of
cuttingline.

4. Ensure that the line is not crisscrossed on the spool as
detailed in Fig. O. If it is, unwind the cutting line, then
wind it back on the spool neatly so that the lines do
notcross.

5. Ensure the beginning of the cutting line is pulled tight
against the spool as shown in Fig.O.

6. Align the tabs on the spool cap with the cut outs in
thehousing.

7. Push the spool cap onto the housing until it snaps
securely intoplace.

8. If the cutting line protrudes beyond the trimming
blade, cut it off so that it just reaches the blade. If the
automatic line feed still does not work or the spool is
jammed, try the following suggestions:

a. Carefully clean the spool andhousing.

b. Remove the spool and check if the lever in the spool

housing can movefreely.

c. Remove the spool and unwind the cutting line,

then wind it on neatly again. Replace the spool into
thehousing.
