Constant Voltage regulator

22CF | 23 | 29CF | 30
Note: Alternatively to battery operation, indus-
trial cordless angle wrenches can also be oper-
ated with a constant voltage regulator.
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 specif-
ic electricity network.
Apart from the 4EXACT constant voltage regula-
tor 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 regula-
tor (LED indicator) 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 series, 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.

These industrial cordless screwdrivers cannot
be operated with constant voltage regulator.
Connection to the Power Supply
Note: Please note that upon delivery neither a
battery pack nor a voltage adapter is inserted in
the power tool.
Never store rechargeable batteries in a bat-
tery powered tool. Rechargeable batteries
last longer and are easier to recharge when
they are stored separately. Remember to ful-
ly recharge batteries that have been stored
for a longer time before use.
Battery Charging
Charge the battery with a suitable charging unit
before inserting it into the power tool. The exact
description of the charging procedure can be
found in the operating instructions of the charg-
ing unit and the hints in this manual (see
"Charging Procedure", page 32).
The battery is equipped with an NTC tempera-
ture sensor that allows charging only in the tem-
perature range between 0 °C (+32 °F) and
45 °C (+113 °F). A long service life of the bat-
tery is achieved in this manner. With correct us-
age, the battery can be recharged up to
3000 times.
A battery that is new or has not been used for a
longer period does not develop its full capacity
until after approx. 5 charging/discharging cycles.
Batteries should only be recharged when the
LED indicator "battery condition" of the power
tool shows red.
Battery insertion/removal
Move the rotational direction switch 14 to the
center position. This action locks the on/off trig-
ger switch 13 in the "off" position, which pre-
vents the tool from running. Insert a fully charged
battery 11 into the handle of the power tools.
Insure that the battery is in the correct position
and that the locking buttons 12 engage securely
into the handle of the power tool.
