Important safety InstructIons for battery packs

WARNING: For safe operation, read this manual and manuals originally supplied with tool before using the charger.

The battery pack is not fully charged out of the carton. Before using the battery pack and charger, read the safety instructions below. Then fol- low charging procedures outlined.

• Do not incinerate the battery pack even if it is severely damaged or is completely worn out. The battery pack can explode in a fire. Toxic fumes and materials are created when battery packs are burned.

• Do not charge or use battery in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Inserting or removing the battery from the charger may ignite the dust or fumes.

• If battery contents come into contact with the skin, immediately wash area with mild soap and water. If battery liquid gets into the eye, rinse water over the open eye for 15 minutes or until irritation ceases. If medical attention is needed, the battery electrolyte for Li-ion batteries is composed of a mixture of liquid organic carbonates and lithium salts.

• Contents of opened battery cells may cause respiratory irritation. Provide fresh air. If symptoms persist, seek medical attention.

WARNING: Burn hazard. Battery liquid may be flammable if exposed to spark or flame.

• Charge the battery packs only in Black & Decker chargers.

• DO NOT splash or immerse in water or other liquids. This may cause premature cell failure.

• Do not store or use the tool and battery pack in locations where the temperature may reach or exceed 105°F (40˚C) (such as outside sheds or metal buildings in summer).

WARNING: Never attempt to open the battery pack for any reason. If battery pack case is cracked or damaged, do not insert into charger. Do not crush, drop or damage battery pack. Do not use a battery pack or charger that has received a sharp blow, been dropped, run over or damaged in any way (i.e., pierced with a nail, hit with a hammer, stepped on). Damaged battery packs should be returned to service center for recycling.

WARNING: Fire hazard. 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. 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 carry-on 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. NOTE: Batteries should not be put in checked baggage.

Storage Recommendations

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

2. Long-term storage will not harm the battery pack or the charger as long as the battery is not depleted..

Charging Procedure

Black and Decker chargers are designed to charge Black and Decker battery packs: LCS36 (2 hrs), LCS436 (6 hrs).

1. Plug the charger into an appropriate outlet before inserting the bat- tery 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.

Recharge discharged batteries as soon as possible after use or bat- tery life may be greatly diminished.

Charger Diagnostics

This charger is designed to detect certain problems that can arise with the battery packs or the power source. Problems are indicated by one LED flashing in different patterns.

Bad battery

The charger can detect a weak or damaged battery. The red LED flashes in the pattern indicated on the label. If you see this

bad battery blink pattern, do not continue to charge the battery. Return it to a service center or a collection site for recycling.

Hot/Cold pack delay

When the charger detects a battery that is excessively hot or

excessively cold, it automatically starts a Hot/Cold Pack Delay,

suspending charging until the battery has normalized. After this happens, the charger automatically switches to the Pack Charging mode. This feature ensures maximum battery life. The red LED flashes in the pattern indicated on the label when the hot / cold pack delay is detected.

Leaving the battery in the charger

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

Important Charging Notes
1. Longest life and best performance can be obtained if the battery
pack is charged when the air temperature is between 60°F and 80°F
(16°- 27°C). DO NOT charge the battery 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 battery pack.
2. The charger and battery pack may become warm to 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 current at 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 charger and battery pack to a location where the surrounding
air temperature is approximately 60°F - 80°F (16° - 27°C).
d. If charging problems persist, take the tool, battery pack and
charger to your local service center.
4. The battery pack should be recharged when it fails to produce suf-
ficient power on jobs which were easily done previously. DO NOT
CONTINUE to use under these conditions. Follow the charging proce-
dure. You may also charge a partially used pack whenever you desire
with no adverse affect on the battery pack.
5. Foreign materials of a conductive nature such as, but not limited to,
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 char-
ger before attempting to clean.
