Bosch 1671B Operating/Safety Instructions Manual page 15

IMPORTANT CHARGING NOTES
1. The charger was designed to fast charge a. Check for voltage at outlet by plugging in
the battery only when the battery temperature
is between 32°F (0°C) and 140°F (60°C). If the
battery pack is too hot or too cold, the charger
will not fast charge the battery. (This may
happen if the battery pack is hot from hea W
use). When the battery temperature returns to
between 32°F (0°C) and 140°F (60°C), the
charger will automatically begin charging.
2. A substantial drop in operating time per charge
may mean that the battery pack is nearing the
end of its life and should be replaced.
3. Remember to unplug charger during storage
period.
4. If battery does not charge properly:
some other electrical device.
b. Check to see if outlet is connected to a
light switch which turns power "off" when
lights are turned off.
c. Check battery pack terminals for dirt.
Clean with cotton swab and alcohol if
necessary.
d. If you still do not get proper charging,
take or send tool, battery pack and
charger to your local Bosch Service
Center. See "Tools, Electric" in the
Yellow Pages for names and addresses.
Note: Use of chargers or battery packs not
sold by Bosch will void the warranty.
CHARGING BATTERY PACK (B0830 1 HOUR CHARGER)
Plug charger cord into your standard power
outlet, then insert battery pack into charger
(Fig. 15).
The charger's green indicator light will begin to
"BLINK". This indicates that the battery is
receiving a fast charge. Fast-charging will
automatically stop when the battery pack is
fully charged.
When the unit beeps and the indicator light
stops "BLINKING" (and becomes a steady
green light) fast charging is complete.
The battery pack may be used even though
the light may still be blinking. The light may
require more time to stop blinking depending
on temperature. When you begin the charging
process of the battery pack, a steady red light
could also mean the battery pack is too hot or
too cold.
The purpose of the green light is to indicate
that the battery pack is fast-charging. It does
not indicate the exact point of full charge. The
light will stop blinking in less time if the battery
pack was not completely discharged.
When needed, the internal fan of the charger
will turn on to aid the charging process and
speed.
When charging several batteries in sequence,
the charge time may slightly increase.
When the battery pack is fully charged, unplug
the charger (unless you're charging another
battery pack) and slip the battery pack back
into the tool.
