IMPORTANT SAFETY INSTRUCTIONS FOR BATTERY CHARGERS SAVE THESE INSTRUCTIONS: This manual contains important safety  instructions for battery chargers.

  • Before using charger, read all instructions and cautionary markings on charger, battery pack, and product using battery pack.
    WARNING: Shock hazard. Do not allow any liquid to get inside charger.
    CAUTION: Burn hazard. To reduce the risk of injury, charge only designated BLACK+DECKER batteries. Other types of batteries may burst  causing personal injury and damage.

CAUTION: Under certain conditions, with the charger plugged in to the power supply, the charger can be shorted by foreign material. 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 charger before attempting to clean.
WARNING: DO NOT attempt to charge the battery pack with any chargers other than the ones in this manual. The charger and battery pack are specifically designed to work together.

  • These chargers are not intended for any uses other than charging designated BLACK+DECKER rechargeable batteries. Any other uses may result in risk of fire, electric shock or electrocution.
  • Do not expose charger to rain or snow.
  • Pull by plug rather than cord when disconnecting charger. This will reduce risk of damage to electric plug and cord.
  • Make sure that cord is located so that it will not be stepped on, tripped over, or otherwise subjected to damage or stress.
  • Do not use an extension cord unless it is absolutely necessary. Use of improper extension cord could result in risk of fire, electric shock, or electrocution.
  • An extension cord must have adequate wire size (AWG or American Wire Gauge) for safety. 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 individual extension contains at least the minimum wire size.

  • 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 appliance 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: Lithium-Ion 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 storage will not harm the battery pack or charger.

CHARGING PROCEDURE
BLACK+DECKER chargers are designed to charge BLACK+DECKER battery packs.

  1. Plug the charger into an appropriate outlet before inserting the battery pack.
  2. Insert the battery pack into the charger as shown in Figure A.BLACK DECKER LSTE523 20V Max String Trimmer - fig1
  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 battery life may be greatly diminished. For longest battery life, do not discharge batteries fully. It is recommended that the batteries be recharged after each use.

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 glowing 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 65°F and 75°F (18°- 24°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 65°F – 75°F (18°- 24°C).
    d. If charging problems persist, take the appliance, battery pack and charger to your local service center.

  4. The battery pack should be recharged when it fails to produce sufficient power on jobs which were easily done previously. DO NOT CONTINUE  to use under these conditions. Follow the charging procedure. 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 charger before attempting to clean.

  6. Do not freeze or immerse charger in water or any other liquid.

  • To return to trimming position, pull the flip-to-edge collar down and rotate the head clockwise back to its original position.
    NOTE: You will experience faster than normal cutting line wear if the trimmer line is positioned directly over the sidewalk or abrasive surface.

EDGING
WARNING: When being used as an Edger, stones, pieces of metal and other objects can be thrown out at high speed by the line. The trimmer and  guard are designed to reduce the danger. However, MAKE SURE that other persons and pets are at least 100 feet (30m) away. Optimum cutting results  are achieved on edges deeper than 2 inches (50 mm).

  • Do not use this trimmer to create trenches.
  • Using the edging wheel (10), guide the trimmer as shown in figure M.
  • Position the edging wheel on the edge of the sidewalk or abrasive surface so the cutting line is over the grass or dirt area to be edged.
  • To make a closer cut, slightly tilt the trimmer.BLACK DECKER LSTE523 20V Max String Trimmer - FigureM

SPEED CONTROL & RUNTIME EXTENSION MODE
This string trimmer gives you the choice to operate at a more efficient speed to extend the runtime for larger jobs, or accelerate the trimmer speed for high-performance cutting ( figure N).

  • To extend runtime, pull the runtime extender switch (5) back toward the battery (13) into position #1. This mode is best for larger projects that require more time to complete.
  • To accelerate the trimmer, push the speed-control switch forward toward the trimmer head (9) into position #2. This mode is best to cut through  heavier growth and for applications that need higher RPM.
    NOTE: When in acceleration mode (#2), runtime will be decreased as compared to when trimmer is in extended runtime mode (#1). BLACK DECKER
LSTE523 20V Max String Trimmer - FigureN

HELPFUL CUTTING TIPS

  • Use the tip of the string to do the cutting; do not force string head into uncut grass. Use edge guide along such things as fences, houses and flower  beds for best practices.
  • Wire and picket fences cause extra string wear, even breakage. Stone and brick walls, curbs, and wood may wear string rapidly.
  • Do not allow spool cap to drag on ground or other surfaces.
  • In long growth cut from the top down and do not exceed 12 inches (304.8 mm) high.
  • Keep trimmer tilted toward the area being cut; this is the best cutting area.
  • The trimmer cuts when passing the unit from the right to left. This will avoid throwing debris at the operator.
  • Avoid trees and shrubs. Tree bark, wood moldings, siding, and fence posts can easily be damaged by the string.

CUTTING LINE / LINE FEEDING
Your trimmer uses .065 inch (1.65 mm) diameter, ROUND nylon line. During use, the tips of the nylon lines will become frayed and worn and the special self feeding spool will automatically feed and trim a fresh length of line. Cutting line will wear faster and require more feeding if the cutting or edging is done along sidewalks or other abrasive surfaces or heavier weeds are being cut. The advanced automatic line feeding mechanism senses when  more cutting line is needed and feeds and trims the correct length of line whenever it’s required. DO NOT BUMP unit on ground in attempt to feed line or for any other purposes.

CLEARING JAMS AND TANGLED LINE (FIGURES O, P, Q)
WARNING: Remove the battery from the trimmer before making any assembly,adjustments or changing accessories. Such preventive safety  measures reduce the risk of starting the appliance accidentally. 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.

  • Remove the battery from the trimmer.

  • Press the release tabs (23) on the line spool cap (24), as shown in figure O and remove the cap by pulling it straight off.BLACK DECKER LSTE523 20V Max String Trimmer - Figure O

  • Pull the nylon line spool out and clear any broken line or cutting debris from the spool area.

  • Place spool and line into spool cap with line “parked” in slots provided as shown in figure P1.

  • Insert the line end through the appropriate hole in the spool housing. Pull slack line through until it pulls out of the holding slots as shown in figure P2.

  • Press the spool down GENTLY and rotate it until you feel it drop into place and then push to snap into place. (When in place, the spool will turn a  few degrees left and right freely).

  • Take care to keep the line from becomingtrapped under the spool.

  • Align the spool cap tabs with the slots on the spool housing.

  • Snap the spool cap back on as shown in figure Q by depressing lugs and pressing into spool housing.BLACK DECKER LSTE523 20V Max String Trimmer - FigureQ

NOTE: Make sure that cover is fully positioned, listen for two audible clicks to ensure both lugs are correctly located. Power the appliance on. In a few  seconds or less you’ll hear the nylon line being cut automatically to the proper length.
CAUTION: To avoid appliance damage, if the cutting line protrudes beyond the trimming blade, cut it off so that it just reaches the blade.
NOTE: Other replacement parts (guards, spool caps, etc.) are available through BLACK+DECKER service centers. To find your local service location call: 1-800-544- 6986 or visit www.blackanddecker.com.
WARNING: The use of any accessory not recommended by BLACK+DECKER for use with this appliance could be hazardous.

REPLACEMENT ACCESSORIES

CAUTION: Before you begin trimming, only use the appropriate type of cutting line. EASYFEED™ uses single line, 0.065” AFS compatible  accessories. Use BLACK+DECKER Model No. AF-100 replacement spool and RC-100-P replacement spool cap.
Reload nylon line (either bulk or prewound replacement spool) as shown in this manual.

  • USE ONLY .065 inch (1.65 mm) DIAMETER ROUND NYLON MONOFILAMENT LINE. Do not use serrated or heavier gauge line, as they  will overload the motor and cause overheating. This line is available at your local dealer or authorized service center.

Troubleshooting

PROBLEM

Trimmer runs slowly.

| SOLUTION

•  Remove battery from trimmer.
•  Check that the spool housing can rotate freely. Carefully clean it if necessary.
•  Check that the cutting line does not protrude more than approximately 4-13/16 inches (122mm) from the spool.
If it does, cut it off so that it just reaches the line trimmingblade.

---|---
TM

EASY FEED does not feed more line.

| •  Keep the tabs depressed and remove the spool from the spool housing in the trimmer head.
•  Ensure that the line is not crisscrossed on the spool as detailed in Figure U. If it is, unwind the cutting line, then wind it back on the spool neatly so that the lines do not cross.
•  Inspect tracks at the bottom of spool for damage. If damaged, replace spool.
•  Pull the cutting line until it protrudes approximately 4-13/16 inches (122mm) from the spool. If insufficient cutting line is left on the spool, install a new spool of cutting line.
•  Align the tabs on the spool cap with the cut outs in the housing.
•  Push the spool cap onto the housing until it snaps securely into place.
•  If the cutting line protrudes beyond the trimming blade, cut it off so that it just reaches the blade. If the automatic line feed still does not work or the spool is jammed, try the following suggestions:
•  Carefully clean the spool and housing.
•  Make sure you are using correct line size and diameter (0.065 inch (1.65 mm))- smaller and larger line sizes will affect the functionality of the auto feed system.
•  Remove the spool and check if the lever in the spool housing can move freely.
•  Remove the spool and unwind the cutting line, then wind it on neatly again. Replace the spool into the housing.
Overfeeding| •  Ensure you are cutting with the tip of the line (7 inches (177.8mm) from the spool). Use the edge guide if needed to ensure proper space is maintained.
•  Ensure you are not exceeding a 10° angle as shown in Figure J1.
Line unravels when cap or spool is removed.| •    Make sure to park the lines in holding slots ( figure S) before removing.
