Charging The Battery; Troubleshooting Guide - Black & Decker NST2018 Instruction Manual

CHARGING THE B ATTERY
1. This manual contains important safety and operating instructions.
2. Before using b attery charger, read allinstructions and cautionary markings on(1)battery charger, (2)
battery, and(3) product using battery.
3. z_CAUTION: Toreduce the risk ofinury, c harge only Black &Decker Power Packs.
Other types of
batteries may burst causing persona 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.

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 I 0 minutes and seek
immediate medical attention. MEDICAL NOTE: The liquid is a 25-35% solution of potassium hydroxide.

LINE FEEDING
Your trimmer uses .065" (1.65mm) diameter nylon line to cut ,qrassand weeds quickly and easily. In time, the tip of
file nylon line will become worn and file auto feed mechanism-will automaticallyfeed and trim a fresh length oFline.
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 senseswhen more cutting line is needed and feeds and trims file
correct lenqth of line whenever it is required. Youdon't even have to think about it. Do not bump unit on ground in
attempt to feed line or for any other purpose.
REPLACINGSPOOL/CLEARING JAMS AND TANGLED LINES

rewind it and insert the line end through the eyelet in the spool hub, as shown in Figure 14. Pullthe line through the
hole to maintain tension while placing file spool clown into the hub with the notched side exposed, as shown in
Figure 15.
• Pressfile spool clown GENTLYand rotate it until you feel itdrop into place. (When in place, the spool will turn a
few degrees left and right freely.)
• Snap the spool cover back on, insert file battery and turn the tool on. In a few seconds or lessyou'll hear tile nylon
line being cut automatically to the proper bngth.

THE BATTERIES IN YOUR POWER PACK ARE NOT FULLYCHARGED AT THE FACTORY.BEFOREAITEMPTING
TO CHARGETHEM, THOROUGHLY READALLOF THE SAFETYINSTRUCTIONS.
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
6 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 6 hours. If the power pack is
run-down completely, it may take up to 6 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 andwill 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 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 of Fwhenyou 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 oca Back & Decker service center. See Too s Eectric in ye ow pages.
5. The power pack should be recharged when it fails to produce sufficient power on jobs which were
easily clone 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 BATTERYPACK 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.
