Bosch Power Tools
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.
– 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.
– 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.
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.
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.
