CHARGING THE BATTERY
1. 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.
2.
Other types of batteries may burst causing personal injury and damage.
3. Do not expose charger to rain or snow.
4. The charger is equipped with a red LED charging indicator light, located on the upper side
of the charger. The indicator light will come on when the battery is properly connected to
the charger and the power plug is inserted into the electrical outlet. The light will remain on,
so long as the unit is properly connected to the powered charging base. It is recommended
to store the unit on the charger during the operating seasons, with the charger plugged in,
to have the battery charged for the next use.
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 sub-
jected 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 let-
ters "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. 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.
10. DO NOT incinerate battery even if they are severely damaged or completely worn out.
11. 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 NOTES
THE CELLS 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 B 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 power pack (Figure C) and slide out.
4. 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 attempt-
ing to use it, it must be charged for at least 9 hours.
5. 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).
6. While charging, the charger may hum and become warm to touch. This is a normal
11
condition and does not indicate a problem.
7. 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 (+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.
8. 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.
9. 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.

2. Lift unit out of soil.
3. Slide lock off button (15) (Fig. I).
4. Pull switch trigger (16). (Fig. I)
For the first cultivating each season, it is best to move slowly because dirt is packed
down. Subsequent cultivating will be completed more rapidly. Do not attempt to
cultivate when the soil is wet - for electrical safety and to prevent clogging of the tines.
If you must cultivate under conditions that cause the tines to become clogged, release
trigger, wait for tines to come to complete stop! REMOVE BATTERY! Remove
clogged material with a stick or screwdriver. To continue to operate the tool in a
clogged condition will seriously overload the motor.
NOTE: This unit is equipped with a built in clutching mechanism used to prevent
permanent damage to the unit due to an obstruction in the tines or overloaded working
conditions. If the clutch is engaged, the unit will make a loud clicking sound. This noise
will persist until the obstruction or overload condition is removed.
Remove battery prior to attempting to remove obstructions from tines. The clutch
mechanism is not adjustable by the user.
CAUTION: Do not attempt to unclog the tines by dropping or tapping the tool on the
ground. This can damage the unit.
STORAGE
Remove and clean any debris from the outside of the cultivator and inside of shroud before
storage. See MAINTENANCE section.
CAUTION: DO NOT HANG ON THE SWITCH TRIGGER
Note: Do not store the tool on or adjacent to fertilizers or chemicals. Such storage can
cause rapid corrosion.
PREVENTING CORROSION
WARNING: Wear proper gloves and eye protection when cleaning tool.
Fertilizers and other garden chemicals contain agents that greatly accelerate the corrosion
of metals. If you use the tool in areas where fertilizers or chemicals have been used, the
tool should be cleaned immediately afterwards.
Wipe all exposed parts with a damp cloth. You may lubricate only metal parts with a light
petroleum based oil.
When cleaning, DO NOT immerse tool in water or spray it with a hose.

MAINTENANCE

Use only mild soap and damp cloth to clean the tool. Never let any liquid get inside the tool;
never immerse any part of the tool into a liquid
IMPORTANT: To assure product SAFETY and RELIABILITY, repairs, maintenance and
adjustment (other than those listed in this manual) should be performed by authorized
service centers or other qualified service organizations, always using identical replacement
parts.
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.
