/ SAFETY WARNINGSAND 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.
3. _, CAUTION: To reduce the risk of injury, charge only Black & Decker Power
Packs. Other types 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 toss 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. MEDICAL 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
FACTORY. BEFORE ATTEMPTING TO CHARGE THEM, THOROUGHLY READ ALL
OF THE SAFETY INSTRUCTIONS.
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 DO power source. Use only 120V
AC.
2. Slide the charger onto the power pack as shown in figure 7 & 8 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 6 to 9 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 9) and slide out.
IMPORTANT CHARGING NOTES
1. After normal usage, your power pack should be fully charged in 6 to 9 hours. If the
power pack is run-down completely, it may take up to 9 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 (24°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 propedy--(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
(+40.5°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 wilt 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 itscharge 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 boseits charge if left in a charger that is not
plugged into an appropriate AC source.

maychoosetofoldthewireedgeguideupoutoftheway.
LINE FEEDING
Your trimmer uses .065 in. (1.65mm) diameter nylon line to cut grass and weeds quickly
and easily. In time, the tip of the nylon line wilt become worn and the auto feed
mechanism wilt 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 offthe trimmer and remove the battery.
• Press the release tabs on the line spool cover, as shown in figure 14 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,
asshown in figure 15. 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 16.
• 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 toot on. In a few seconds or
less you'll hear the nylon line being cut automatically to the proper length.
REWINDING SPOOL FROM BULK LINE (USE ONLY .065 IN. DIAMETER LINE)
Bulk line for your trimmer/edger is available at extra cost from your local dealer or Black
& Decker Service Center.
To install bulk line, follow the steps below.
• Turn offthe trimmer and remove the battery.
• Press the release tabs on the line spool cover, as shown in figure 14 and remove the cover
by pulling it straight off.
• Remove the spool from the tool and remove and discard all line on the spool.
• Insert one end of the bulk line into the hole in the spool shown in figure 17 about 1/2 in.
(12mm).
• Hold the line in the hole and pull the rest of the line through the slot in the spool, shown
in figure 17.
• Snugly and evenly wind the bulk line onto the spool inthe direction of the arrow on spool in
figure 17 until it is nearly full. (The spool holds 50 ft. (15.2m) of line and bulk line is sold in
50 foot sections.)
• Insert the lineend through the eyelet inthe spool hub, as shown infigure 15. 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 16.
• 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 toot on. In a few seconds or
less you'll hear the nylon line being cut automatically to the proper length.
