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
Before assembling your Cordless String Trimmer, check that you have received the following in
the shipping carton. See Figure 1.
A. Guard. C. Nicad Battery Pack. E. Auxiliary Handle.
B. Charger. (NOT SHOWN) D. Trimmer/Edger.
ATTACHING THE GUARD
• WARNING: NEVER OPERATE TOOL WITHOUT GUARD FIRMLY IN PLACE. THE
GUARD MUST ALWAYS BE ON THE TOOL TO PROTECT THE USER.
• Assemble the guard as shown in Figure 2, over the lug on the motor housing, then slide
guard forward to lock on the lug. Then with a phillips screw driver, screw the preassembled
screws in the guard into the motor housing. Figure 3.
AUXILIARY HANDLE ADJUSTMENT
• For maximum comfort and control, adjust the auxiliary handle to suit your height (Figure
4A). Shorter users adjust handle to a lower position (away from you) and taller users, adjust
handle to an upper position (towards you). The handle should be adjusted so that your front
arm is straight as shown in Figure 9.
HEIGHT ADJUSTMENT
• The overall height of the trimmer can be adjusted by loosening the lock collar and rotating it
opposite to the arrow shown in Figure 4B. The tubes can then be extended shorter or
longer. When the desired height is achieved tighten the collar by rotating in the direction
shown in Figure 4B.
OPERATING INSTRUCTIONS
• CAUTION: ALWAYS WEAR EYE PROTECTION.
• CAUTION: 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.
OPERATE 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 .065” (1.65mm) diameter nylon line 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.
REWINDING SPOOL FROM BULK LINE (USE ONLY .065” 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 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.
• 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 16 about 1/2” (12mm).
• Hold the line in the hole and pull the rest of the line through the slot in the spool, shown in
Figure 16.
• Snugly and evenly wind the bulk line onto the spool in the direction of the arrow on spool in
Figure 16 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 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.
BATTERY CAP INFORMATION
Battery storage and carrying caps are provided for use whenever the battery is out of the
unit or charger. Remove cap before placing battery in charger or unit.
WARNING: Do not store or carry battery so that metal objects can contact
exposed battery terminals. For example, do not place battery in aprons, pockets, tool boxes,
product kit boxes, drawers, etc. with loose nails, screws, keys, etc. without battery cap.
Transporting batteries can possibly cause fires if the battery terminals inadvertently come in
contact with conductive materials such as keys, coins, hand tools and the like. The US
Department of Transportation Hazardous Material Regulations (HMR) actually prohibit
transporting batteries in commerce or on airplanes (i.e. packed in suitcases and carryon
luggage) UNLESS they are properly protected from short circuits. So when transporting
individual batteries, make sure that the battery terminals are protected and well insulated
from materials that could contact them and cause a short circuit."
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.
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 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.
CHART FOR MINIMUM WIRE SIZE (AWG) OF EXTENSION CORDS
NAMEPLATE RATING AMPS – 0 – 10.0
Total Extension Cord Length (ft) 25 50 75 100 125 150
Wire Gauge 18 18 16 16 14 14
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 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 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 8) and slide out.
IMPORTANT CHARGING NOTES
1. After normal usage, your power pack should be fully charged in 3 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 con-
dition 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 sur-
rounding 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 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.
