EXACT tools in another part of the assembly
process where the torque is set to 7.5 Nm, you
can use another marking ring (such as black,
blue, green or yellow) to mark the torque range
of these units. The different marking rings are
only intended as a quick reference for produc-
tion personnel to easily indentify which tool is
set for a given torque range.
Press off the marking ring 17 with a thin screw-
driver blade, a knife, or similar.
Always use the power tool with a marking ring to
insure that the housing body is sealed from dust
and dirt.
LED Indicators
Battery Condition Indicator
If the charging of the battery 11 is nec-
essary, the LED indicator 10 blinks
green and an acoustical signal sounds.
Only 6 – 8 screwing operations may be possible.
When the LED indicator lights up red, the capac-
ity is no longer sufficient for a new screw con-
nection or the power tool has been subject to
overload. The power tool can not be switched
on anymore. The start lock remains active until
the battery pack is removed from the power tool
and a charged battery pack is inserted again.
When working with a voltage adapter, the red
LED indicator 10 indicates an overload.
When the LED indicator 10 blinks red, the power
tool is overheated and can no longer be
switched on. Wait until the blinking automatical-
ly stops after a short period before continuing to
work again with the power tool.
A considerably shortened operating time of the
power tool after each charging indicates that
the battery must be replaced soon. Dispose of
the used battery in accordance with the le-
gal/country-specific regulations.
Screwing Fastener Indicator
When the preset torque is reached, the
shut off coupling responds. The LED
indicator 9 lights green.
If the preset torque is not reached, the LED in-
dicator 9 lights red and an acoustical signal
sounds. The screwing fastener must be per-
formed again.
Bosch Power Tools
Repeat Protection
When the shut-off coupling responds for a
screwing fastener, the motor shuts off. Switch-
ing on again is possible only after a 0.7 second
delay. In this manner, an unintentional re-tight-
ening of an already seated screw is avoided.
Adjusting the Angled Drive Head
ANGLE EXACT 2 | 3 | 6 | 7 | 7 – 900 | 8 |
10 – 650 | 14 – 420 | 15 | 17 |
23 | 30
The angled drive head 3 can be adjusted to a to-
tal of eight positions.
Hold the power tool with the open-end spanner 6
by the spanner flats 5 of the angled head flange.
Never clamp the tool by the housing shells!
Loosen the sleeve nut with the open-end span-
ner 4 by the spanner flats 19. Adjust the angled
drive head 3 in 45° steps to the desired position
and retighten the sleeve nut again with the
open-end spanner 4 by the spanner flats 19.
Hold the angled head flange with the open-end
spanner 6 to prevent turning.
ANGLE EXACT 14CF | 22CF | 29CF
Please observe the information of your bought-
out flat drive or inquire at your specialist shop.
Adjusting and Removing the Angled Drive
Head (see figure K)
ANGLE EXACT 25 – 250 | 30 – 380 | 40 – 280 |
50 – 210
The angled drive head 3 with tool bit holder 2
can be continuously adjusted around 360°.
Loosen the lock nut 20 by inserting an appropri-
ate tool into an opening of the lock nut and turn-
ing the lock nut in the direction of the arrow a
(left thread).
Turn the angled drive head 3 in arrow direction
b until the desired work angle is reached, but
not more than once by 360°.
Lock the angled drive head 3 in this position by
turning lock nut 20 in arrow direction c against
the angled drive head. Retighten lock nut 20
again with a tightening torque of approx. 50 Nm.
The angled drive head 3 can also be removed
completely, e.g. when it is required to replace
the marking ring 17 by one with another colour
