4. The completion of charge is indicated by the LED
remaining on continuously. The pack is fully charged and
may be used at this time or left on the charger.
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 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
light flashes in the pattern indicated on the label.
LEAVING THE BATTERY IN THE CHARGER
The charger and battery pack can be left connected with the
LED glowing indefinitely. The charger will keep the battery pack
fresh and fully charged. This charger features an automatic
tune-up mode which equals or balances the individual cells in
the battery pack to allow it to function at peak capacity. Battery
packs should be tuned up weekly or whenever the battery no
longer delivers the same amount of work. To use the automatic
tune-up mode, place the battery pack in the charger and leave
it for at least 8 hours.
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 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.
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.
WARNING: Shock hazard. Do not allow any liquid to get
inside charger.Never attempt to open the battery pack for
any reason. If the plastic housing of the battery pack
breaks or cracks, return to a service center for recycling.
OPERATING INSTRUCTIONS
Installing and Removing the Battery Pack From the Tool
CAUTION: Make certain the lock-off button is engaged to
prevent switch actuation before emoving or installing
battery.
1. To install battery pack: Insert battery pack (6) into tool as
shown in Figure C.
2. To remove battery pack: Depress the battery release
button (7) as shown in Figure D and pull battery pack out
of tool.
3. Variable Speed Trigger Switch (Figure E)
To turn the tool on, squeeze the trigger switch (1). To turn
the tool off, release the trigger switch. Your tool is
equipped with a brake. The chuck will stop as soon as the
trigger switch is fully released. The variable speed switch
enables you to select the best speed for a particular
application. The more you squeeze the trigger, the faster
the tool will operate. Use lower speeds for starting holes
without a center punch, drilling in metals or plastics, or
driving screws. For maximum tool life, use variable speed
only for starting holes or fasteners.
NOTE: Continuous use in variable speed range is not
recommended. It may damage the switch and should be
avoided.
4. Forward/Reverse Control Button (Figure F)
A forward/reverse control button (2) determines the
direction of the tool and also serves as a lock off button.
To select forward rotation, release the trigger switch and
depress the forward/reverse control button on the right
side of the tool. To select reverse, depress the
forward/reverse control button on the left side of the tool.
