The industrial cordless screwdrivers are supplied without in-
sertion tools, battery pack, battery charger, constant voltage
regulator or voltage adapters. The voltage adapters are to be
used exclusively to connect Bosch industrial cordless screw-
drivers to the constant voltage regulator 4EXACT.

The industrial cordless screwdrivers are supplied without in-
sertion tools, battery pack or battery charger. These power
tools are not suitable for operation with constant voltage reg-
ulator.
Operating and Storage Environment
The device is suitable exclusively for operation at en-
closed work sites. For trouble-free operation of the
device, the allowed ambient temperature should lie
between –5 °C and +50 °C (23 °F and 122 °F) at an allowed
relative humidity of between 20 and 95 %, free of dew.
In order to avoid damage to the battery cells, the battery pack
should be stored within a temperature range between 0 °C
(32 °F) and 45 °C (113 °F).
Charging Procedure
Note: Battery charger and battery packs are not included in
the delivery scope. The power plug shown can vary from the
one on your power tool.
 Please take care, that the charger and the battery pack
are suitable for your country specific electricity net-
work.
Battery Charger AL 2450 DV (see figure A)
Plug the power plug 12 of the battery charger 11 into your
electrical power supply outlet and insert the battery 5 cor-
rectly into the charging compartment of the battery charger.
 Do not exert any force when inserting/removing the
battery. Batteries with APT contact (Akku Pack Top) are
designed in such a manner that they can only be inserted
into the power tool or the charger in the correct position.
The green LED indicator 13 starts to flash. This indicates the
flow of the charging current. The charging process automati-
cally stops when the battery is fully charged. The charging
Bosch Power Tools
procedure is over when the green LED indicator no longer
flashes and lights up uniformly. An audible signal sounds for
approx. 2 seconds and signals that the battery is fully
charged.
Continuous lighting of the red LED indicator 14 signals a
charging procedure with reduced charging current. When the
red LED indicator flashes, charging is not possible.
Troubleshooting – Causes and Corrective Measures

Constant Voltage regulator (see figure B)
Type 0 602 490 431/... 433/... 435/... 437/
... 439/... 441/... 443/... 471/
... 447/... 469
Note: As an alternative to battery operation, centre grip
screwdrivers can also be operated of a constant voltage regu-
lator. The constant voltage regulator and the voltage adapters
are not included. The power plug shown can vary from the one
on your power tool.
 Please take care, that the constant voltage regulator is
suitable for your country specific electricity network.
Apart from the 4EXACT constant voltage regulator and the
matching power cable, a voltage adapter with the same rated
voltage as your cordless screwdriver is required.
 The voltage on the constant voltage regulator (LED in-
dicator) must be the same as the voltage of the driver.
The constant voltage regulator is suitable exclusively for
Bosch industrial battery-operated drivers of the EXACT se-
ries, the ANGLE EXACT series, and the BT-EXACT series
with a voltage of between 9.6 V and 14.4 V. Otherwise,
there exists the risk of fire and explosion.
