SAFETY WARNINGS AND INSTRUCTIONS
CHARGING THE BATTERY
1. This manual contains important safety and operating instructions.
2. Before using battery charger, read all instructions and cautionary markings on (1) battery
charger, (2) battery, and (3) product using battery.
CAUTION:
To reduce the risk of injury, charge only Black & Decker Power Packs.
3.
Other types of batteries may burst causing personal injury and damage.
4. Do not expose charger to rain or snow.
5. Use of an attachment not recommended or sold by Black & Decker may result in a risk
of fire, electric shock, or injury to persons.
6. To reduce risk of damage to electric plug and cord, pull by plug rather than cord when
disconnecting charger.
7. Make sure cord is located so that it will not be stepped on, tripped over, or otherwise
subjected to damage or stress.
8. An extension cord should not be used unless absolutely necessary. Use of improper
extension cord could result in a risk of fire, electric shock or electrocution.
a. Two-wire cords can be used with 2-wire or 3-wire extension cords. Only round jacketed
extension cords should be used, and we recommend that they be listed by Underwriters
Laboratories (U.L.). If the extension is to be used outside, the cord must be suitable for
outdoor use. Any cord marked for outdoor use can also be used for indoor work. The
letters "W" or "WA" on the cord jacket indicate that the cord is suitable for outdoor use.
b. An extension cord must have adequate wire size (AWG or American Wire Gauge) for
safety, and to prevent loss of power and overheating. 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. When using more than one extension to make up the total length, be sure
each extension contains at least the minimum wire size.

9. Use only the supplied charger when charging your unit. The use of any other charger
could damage the battery or create a hazardous condition.
10. Do not attempt to open the charger or the unit. There are no customer serviceable parts
inside. Return to any authorized Black & Decker service center.
11. DO NOT incinerate battery packs even if they are severely damaged or completely worn
out.
12. Do not incinerate the batteries. They can explode in a fire. A small leakage of liquid from
the battery cells may occur under extreme usage, charging or temperature conditions.
This does not indicate a failure. However, if the outer seal is broken and this leakage
gets on your skin:
a. Wash quickly with soap and water.
b. Neutralize with a mild acid such as lemon juice or vinegar.
c. If the battery liquid gets in your eyes, flush them with clean water for a minimum of 10
minutes and seek immediate medical attention. M E D I C A L NOTE: The liquid is a 25-35%
solution of potassium hydroxide.

IMPORTANT CHARGING SAFETY INSTRUCTIONS
CHARGING THE POWER PACK
THE BATTERIES IN YOUR POWER PACK ARE NOT FULLY CHARGED AT THE
FA C TO RY. BEFORE ATTEMPTING TO CHARGE THEM, THOROUGHLY READ A L L O F
THE SAFETY I N S T R U C T I O N S .
The charger is designed to use standard household 120 volt 60 Hz power.
1. Plug the charger into any standard 120 Volt 60 Hz electrical outlet. NOTE: Do not charge
by means of an engine generator or DC power source. Use only 120V AC.
2. Slide the charger onto the power pack as shown in Figure 6 & 7 and let the power pack
charge initially for 9 hours. After the initial charge, under normal usage, your power pack
should be fully charged in 3 to 6 hours.
3. Unplug charger, and remove the power pack. Place the power pack in the unit and be
certain that it is inserted fully into the battery cavity until it "clicks" into place.
NOTE: To remove the power pack from the unit, press down on the release button on
the back of the pack (Figure 8) and slide out.
I M P O R TANT CHARGING NOTES
1. After normal usage, your power pack should be fully charged in 3 to 6 hours. If the
power pack is run-down completely, it may take up to 6 hours to become fully charged.
Your power pack was sent from the factory in an uncharged condition. Before attempting
to use it, it must be charged for at least 9 hours.
2. DO NOT charge the power pack in an air temperature below +40°F(+4.5°C), or above
+105°F (+40.5°C). This is important and will prevent serious damage to the power pack.
Longest life and best performance can be obtained if power pack is charged when air
temperature is about 75°F (2 4 ° C ).
3. While charging, the charger may hum and become warm to touch. This is a normal
condition and does not indicate a problem.
4. If the power pack does not charge properly—(1) Check current at receptacle by plugging
in a lamp or other unit. (2) Check to see if receptacle is connected to a light switch which
turns power off when you turn out the lights. (3) Move charger and power pack to a
surrounding air temperature of 40°F (+4.5°C) to 105°F ( + 4 0 . 5 ° C ). (4) If the receptacle
and temperature are OK, and you do not get proper charging, take or send the power
pack and charger to your local Black & Decker service center. See Tools Electric in
yellow pages.
5. The power pack should be recharged when it fails to produce sufficient power on jobs
which were easily done previously. DO NOT CONTINUE using unit with its power pack in
a depleted condition.
6. The power pack will reach optimum performance after being cycled 5 times during normal
usage. There is no need to run the batteries down completely before recharging. Normal
usage is the best method of discharging and recharging the power pack.
LEAVING THE BATTERY PACK IN THE CHARGER
The charger and battery pack can be left connected with the red light glowing indefinitely.
The charger will keep the battery pack fresh and fully charged.
NOTE: A battery pack will slowly lose its charge when kept out of the charger. If the battery
pack has not been kept on maintenance charge, it may need to be recharged before use. A
battery pack may also slowly lose its charge if left in a charger that is not plugged into an
appropriate AC source.
ASSEMBLY INSTRUCTIONS

OPERATING INSTRUCTIONS
CAUTION:
A LWAY S W E A R E Y E P R O T E C T I O N .
•
C A U T I O N :
Inspect area to be trimmed and remove any wire, cord, or string-like objects
•
which could become entangled in the rotating line or spool. Be particularly careful to avoid
any wire which might be bent outwardly into the path of the tool, such as barbs at the base of
a chain link fence.
O P E R ATE THE TRIMMER/EDGER
• To turn trimmer on, pull the lock out button, shown in Figure 5, back and, then squeeze the
trigger switch. To turn the tool off, release the trigger.
• Slowly swing trimmer side-to-side as shown in Figure 9.
• To convert for maintenance edging, turn off the tool. (See Figure 10) Holding the trimmer with one
hand by the auxiliary handle, grasp the collar and push in direction of arrow and rotate the
trimmer head until it stops, (half turn), release your hand, (rotate clockwise when viewed from the
switch
end).
The tool is locked in the edger position.
Rotate the wire edge guide forward and down into place before edging, as shown in Figure 11 .
• To operate as a maintenance edger, position trimmer above sidewalk as shown in Figure 12.
• Return to trimming position by turning the tool off, push in direction of arrow and rotating the
trimmer head counter clockwise until it stops. When using the tool in the trimmer mode you may
choose to fold the wire edge guide up out of the way.
LINE FEEDING
Your trimmer uses 1.5mm diameter nylon line (AF-150-04 spool) to cut grass and weeds
quickly and easily. In time, the tip of the nylon line will become worn and the auto feed
mechanism will automatically feed and trim a fresh length of line.
The cutting line will wear faster if the cutting is done along sidewalks or other abrasive
surfaces or heavier weeds are being cut. The automatic feed mechanism senses when more
cutting line is needed and feeds and trims the correct length of line whenever it is required.
You don't even have to think about it. Do not bump unit on ground in attempt to feed line or
for any other purpose.
REPLACING SPOOL/CLEARING JAMS AND TANGLED LINES
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.
• Turn off the trimmer and remove the battery.
• Press the release tabs on the line spool cover, as shown in Figure 13 and remove the cover
by pulling it straight off.
• Lift the spool of nylon line out of the hub and clear any broken line or cutting debris from the
spool area.
• In case of jams and tangled line unwrap about one foot (30cm) of line to ensure that it is
undamaged. If it is OK rewind it and insert the line end through the eyelet in the spool hub,
as shown in Figure 14. Pull the line through the hole to maintain tension while placing the
spool down into the hub with the notched side exposed, as shown in Figure 15.
• Press the spool down GENTLY and rotate it until you feel it drop into place. (When in place,
the spool will turn a few degrees left and right freely.)
• Snap the spool cover back on, insert the battery and turn the tool on. In a few seconds or
less you'll hear the nylon line being cut automatically to the proper length.

THE RBRC™ SEAL
The RBRC™ (Rechargeable Battery Recycling Corporation) Seal on the
nickel-cadmium battery (or battery pack) indicates that the costs to recycle the
battery (or battery pack) at the end of its useful life have already been paid by
Black & Decker. In some areas, it is illegal to place spent nickel-cadmium batteries in the
trash or municipal solid waste stream and the RBRC program provides an environmentally
conscious alternative.
RBRC in cooperation with Black & Decker and other battery users, has established
programs in the United States and Canada to facilitate the collection of spent nickel-
cadmium batteries. Help protect our environment and conserve natural resources by
returning the spent nickel-cadmium battery 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, or call 1-800-8-BATTERY.
