1. The charger was designed to fast charge the
battery only when the battery temperature is
between 32˚F (0˚C) and 113˚F (45˚C). If the
battery pack is too hot or too cold, the charger will
not begin charging the battery. (This may happen
if the battery pack is hot from heavy use). Once
the batte ry tempera tur e returns to i ts safe
charging temperature, between 32°F (0°C) and
113°F (45°C), the charger will automatically
begin charging.
2. A su bstan tial dr op in opera ting ti me per

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:
a. Check for voltage at outlet by plugging in
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 and charger
connectors 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.

Battery Disposal
Do not attempt to disas-semble the battery
or remove any com ponent projecting from
the battery terminals. Fire or injury may result.
Prior to disposal, protect exposed terminals
with heavy insulating tape to prevent shorting.
Lithium-ion Batteries
If equipped with a lithium-ion battery, the
battery must be collected, recycled or disposed
of in an environ mentally sound manner.
“The EPA certified RBRC Battery
Recycling Seal on the lithium-ion
(Li-ion) battery indicates Robert
Bo sch To ol Corporation is
voluntarily participating in an
industry program to collect and recycle these
batteries at the end of their useful life, when
taken out of service in the United States or
Canada. The RBRC pr ogr am pr ovi des a
convenient alterative to placing used Li-ion
batteries into the trash or the munici pal waste

Extension Cords
AN EXTENSION CORD
SHOULD NOT BE USED
UNLESS ABSOLUTELY NECESSARY. Use
of improper extension cord could result in risk
of fire and electrical shock. If an extension cord
is used, make sure:
a. The pins on plug of extension cord are the
same number, size, and shape as those of plug
on charger.
b. The extension cord is properly wired and in
good electrical condition.
c. The wire size is large enough for AC ampere
rating of charger as specified below:
d. An extension cord is a temporary solution.
Move the charger to a standard receptacle as
soon as the job has been completed.
