Starting Operation - Bosch ANGLE EXACT 12V-12-400 Manual Original

Adjusting the 12 V angle head
The angled screw head (3) with tool holder (2) can be con-
tinuously adjusted by 360°.
– Loosen the lock nut (18) by hooking a suitable tool (hook
spanner DIN 1810 form B size 25/28) into an opening on
the lock nut and turning it in the direction of the arrow a
(left-hand thread). While doing so, a suitable tool (hook
spanner DIN 1810 form B size 20/22) must be hooked
into an opening on the angle head and held.
Never clamp the power tool to the housing shells.
u
– Turn the angled screw head (3) in the direction of the ar-
row b until the required working angle is reached; how-
ever, it should only be turned a maximum of one 360° ro-
tation.
– Fix the angled screw head (3) in this position by turning
the lock nut (18) in the direction of the arrow c against
the angled screw head. Tighten the lock nut (18) to the
correct tightening torque (see "Technical Data", page 18)
again. While doing so, a suitable tool must be hooked into
an opening on the angle head and held.
The thread and flange thread must be free from grease
u
and the correct torque (see "Technical Data", page 18)
must be used so that the angle head cannot come loose.
Configuring the power tool
You can configure various settings on the power tool (e.g. ro-
tational speed, screwing stage, repeat protection) using
BOSCH EXACT Configurator software of version 5.2 or
higher. The power tool must be connected to a PC via its
USB port in order to do this. Use a USB cable for this:
USB 2.0 Type A/Micro-USB 2.0 Type B
– Double-shielded
– Max. length 1 m
Note: Follow all the safety instructions and information in
the software manual.
Changing the tool at the screw head with
external square (see figure E)
Inserting the application tool
– Press the pin into the square of the tool holder (2), e.g.
using a narrow screwdriver, and slide the application tool
(1) over the square. Ensure that the pin engages in the re-
cess of the application tool.
Removing the application tool
– Press the pin into the recess of the application tool (1)
and pull the application tool off of the tool holder (2).
Changing the tool at the screw head with
internal hexagon (see figure F)
Inserting the application tool
– Insert the application tool (1) into the internal hexagon of
the tool holder (2) until it audibly engages.
Bosch Power Tools
Removing the application tool
– Pull the application tool (1) off of the tool holder (2), us-
ing pliers if necessary.
Changing the tool at the screw head with quick-
change chuck (see figure G)
Inserting the application tool
Only use application tools with the matching shank (1/4"
hexagon).
– Pull the sleeve of the quick-change chuck (19) forwards.
– Place the application tool (1) into the tool holder (2) and
release the quick-change chuck again.
Removing the application tool
– Pull the sleeve of the quick-change chuck (19) forwards.
– Take the application tool (1) out of the tool holder (2) and
release the quick-change chuck again.
Operation

Starting Operation

Always set the rotational direction using the rotational direc-
tion switch (9) before starting the power tool:
The power tool will not start if the rotational direction switch
(9) is in the centre (lock-off button).
Setting the rotational direction (see figure H)
– Clockwise: To drive in screws, press the rotational direc-
tion switch (9) through as far as possible to the left.
– Anti-clockwise: To loosen or unscrew screws, press the
rotational direction switch (9) through as far as possible
to the right.
Switching on/off
The screwdrivers have a torque-dependent
shut-off clutch that can be set to a value in the
specified range. The clutch is triggered when
the set torque is reached.
– To switch on the power tool, press the on/off switch (8)
down fully.
– The power tool will switch off automatically when the
set torque is reached.
If the on/off switch (8) is released too early, the pre-
u
set torque will not be reached.
Temperature Dependent Overload Protection
In the event of overload, the power tool switches off until it
returns to the optimum operating temperature range. Re-
lease the on/off switch (8) and switch the power tool back
on to continue working.
The power tool is not operated at optimum efficiency at rota-
tional speeds lower than 50 %. This may cause the temperat-
ure dependent overload protection to be activated sooner.
Set the output speed higher than 50 % or reduce the max-
imum torque used if you have problems with these settings.
