quickly 3 times, and then resume blinking continuously. The

continuously. The pack is fully charged and may be used at this
time or left in the charger.

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.
3. If the battery 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 battery pack to a
location where the surrounding air temperature is approximately
65°F - 75°F (18°- 24°C). (4) If charging problems persist, take or
send the tool, 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.
TROUBLE INDICATORS: D
certain problems that can arise with battery packs which would be
indicated by the red light flashing at a fast rate (and continuous beeping
for 15 Minute Chargers). If this occurs, re-insert battery pack. If
problem persists, try a different battery pack to determine if the charger

is OK. If the new pack charges correctly, then the original pack is
defective and should be returned to a service center for recycling. If the
new battery pack elicits the same trouble indication as the original,
have charger tested at an authorized service center.
CHARGER CLEANING INSTRUCTIONS:
WARNING: Disconnect the charger from the AC outlet before
cleaning. Dirt and grease may be removed from the exterior of the
charger using a cloth or soft non-metallic brush. Do not use water or
any cleaning solutions.
