11. DO NOT incinerate the tool or batteries even if they are severely damaged or
completely worn out. The batteries can explode in a fire.
12. 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.
CHARGING THE BATTERY
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. NOTE: Do not
charge by means of an engine generator or DC power source. Use only 120V AC.
1. Plug the charger into any standard 120 Volt 60 Hz electrical outlet.
2. Slide the charger onto the battery pack as shown in Figure A and let it 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. Remove pack from the charger and place in tool. NOTE: To remove the battery from
the saw, press down on the release button on the back of the battery (Figure B) and
pull out.
IMPORTANT CHARGING NOTES
1. After normal usage, your power pack should be fully charged in 3 hours or less. 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 or above 105°F.
This is important and will prevent serious damage to the power pack. Longest life and
best performance can be obtained if the power pack is charged when the air
temperature is about 75°F.
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 appliance. (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 to 105°F. (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 saw with its power
pack in a depleted condition.
6. To prolong power pack life, avoid leaving the power pack on charge for more than 8
hours. Although overcharging is not a safety concern, it can significantly reduce overall
power pack life.
