Switching On and Off
The screwdriver have a shut-off clutch that
depends on the torque and can be set in the
given range. It responds when the torque that
is set is reached.
– To start the machine press the on/off switch 10 to the
stop.
– The machine switches off automatically as soon as the
preset torque is reached.
 When the on/off switch 10 is released prematurely, the
preset torque is not reached.
To save energy, only switch the power tool on when using it.
Working Advice
 Apply the power tool to the screw/nut only when it is
switched off. Rotating tool inserts can slip off.
Setting the Torque (see figures J – K)
The tightening torque is dependent on the spring pretension
of the shut-off clutch. The shut-off clutch responds in right as
well as left rotation when the torque setting is reached.
For setting the individual tightening torques, use only the ad-
justment tool 25 provided.
– Push the torque selector switch 6 on the power tool com-
pletely back.
ANGLE EXACT ION
Applies for the fol-
lowing types: 8-1100 | 15-500 | 23-380 | 30-290
– Insert an Allen key 26 into tool bit 1 and turn it slowly.
– When a small indentation (adjusting dial 27) is visible in
the clutch, insert the adjustment tool 25 into the indenta-
tion and turn it.

Applies for the fol-
lowing types: 30-300 | 40-220 | 50-210 | 60-120
– Slowly turn the tool holder 2 using an open-end spanner.
– When a small indentation (adjusting dial 27) is visible in
the clutch, insert the adjustment tool 25 into the indenta-
tion and turn it.
Turning in the clockwise direction results in a higher torque, in
the counterclockwise direction, a lower torque.
– Remove the adjustment tool 25. Shut the torque selector
switch 6 again to protect the clutch against contamination.
Note: The required adjustment is dependent on the type of
threaded connection and can be best determined by practical
trials. Check the trial screwings with a torque wrench.
 Set the torque only in the specified performance range,
otherwise the shut-off clutch will no longer respond.
Marking the Torque Setting (see figure L)
Always use the power tool with a marking ring to insure that
the housing body is sealed from dust and dirt.
Applies for the fol- ANGLE EXACT ION
lowing types: 30-300 | 40-220 | 50-210 | 60-120
For these industrial cordless angle wrenches, the angled
screw head must be removed first, see "Adjusting and Remov-
ing the Angled Drive Head", page 19.
The torque can be marked now as described below.
1 609 92A 0CM | (6.12.13)
Applies for the fol- ANGLE EXACT ION
lowing types: 8-1100 | 15-500
To identify individually adjusted tightening torques, the mark-
ing ring 17 an be replaced with a marking ring of another
color.
– Press off the marking ring 17 with a thin screwdriver blade,
a knife, or similar.
Screwing Fastener Indicator (green/red LED)
When the preset torque is reached, the shut off coupling re-
sponds. The LED indicator 7 lights green.
If the preset torque is not reached, the LED indicator 7 lights
red and an acoustical signal sounds. The screwing fastener
must be performed again.
Repeat Protection
When the shut-off coupling responds for a screwing fastener,
the motor shuts off. Switching 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.

Maintenance and Service

Maintenance and Cleaning
 Before any work on the machine itself (e. g. mainte-
nance, tool change, etc.) as well as during transport
and storage, remove the battery from the power tool.
There is danger of injury when unintentionally actuating
the On/Off switch.
 For safe and proper working, always keep the machine
and ventilation slots clean.
Power Tool Lubrication
Lubricants:
Special gearbox grease (225 ml)
Article number 3 605 430 009
Molycote grease
SAE 10/SAE 20 engine oil
– Clean the gearbox after the first 150 running hours using a
mild solvent. Follow the solvent manufacturers directions
for use and disposal. Lubricate the gearbox using Bosch
gearbox lube. Repeat the lubrication procedure every
300 hours after the initial gearbox service.
– Oil the moving parts of the shut-off clutch after 100000
screwing operations with a few drops of SAE 10/SAE 20
motor oil. Lubricate the sliding and rolling parts with Moly-
cote grease. At this time, inspect the clutch for wear in or-
der to ensure that the repeatability and accuracy have not
been affected. Afterwards, the torque of the clutch must
be readjusted.
 Have maintenance and repair work performed only by
qualified specialists. In this manner, it can be ensured
that the safety of the power tool is maintained.
An authorized Bosch after-sales service agent will carry out
this work quickly and reliably.
 Observe all applicable environmental regulations when
disposing of old grease and solvents.
