Setting the torque (see figure C)
The torque depends on the spring preload of the shut-off
clutch. The shut-off clutch is triggered upon reaching the set
torque, both in clockwise and anticlockwise rotation.
Only use the supplied adjustment tool (12) to set the indi-
vidual torque.
– Turn the cover for the clutch (1) until both openings over-
lap.
– Insert the application tool (12) into the small protrusion
(setting disc (13)) of the clutch and turn the adjustment
tool (12).
Turning clockwise will result in a higher torque; turning anti-
clockwise will result in a lower torque.
– Remove the adjustment tool (12). Turn the cover for the
clutch (1) until the opening is closed to protect the clutch
from contamination.
Note: The required setting is dependent on the type of
threaded connector and can be best determined by practical
trials. Check a trial screw application with a torque spanner.
If you set the torque to a value outside the specified
u
power range, the shut-off clutch will not be triggered.
Check the torque on the screw connection regularly
u
and readjust the shut-off clutch if necessary.
Switching on/off
The screwdrivers have a torque-dependent
shut-off clutch that can be set to a value in the
specified range. It responds when the set
torque is reached.
– To switch on the power tool, press the on/off switch (8)
as far as it will go.
– 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.
Check the torque on the screw connection regularly
u
and readjust the shut-off clutch if necessary.
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.
Practical advice
Only apply the power tool to the screw/nut when the
u
tool is switched off. Rotating tool inserts can slip off.
Screwdriving indicator (green/red LED)
The shut-off clutch is triggered upon reaching the preset
torque. The LED indicator (3) lights up green.
1 609 92A 9SK | (09.08.2024)
If the preset torque has not been reached, the LED indicator
(3) lights up red and the tool emits a sound. The screw must
be driven in again.
Repeat protection
If the shut-off clutch is triggered while driving a screw, the
motor will switch off. You will need to wait 0.7 seconds be-
fore you can switch the tool on again. This prevents you from
accidentally retightening screws that are already firmly in
place.
Maintenance and Service
Maintenance and Cleaning
Before carrying out any work on the power tool (e.g.
u
maintenance, tool change etc.), remove the battery
from the power tool. There is risk of injury from uninten-
tionally pressing the on/off switch.
To ensure safe and efficient operation, always keep
u
the power tool and the ventilation slots clean.
Check the entire power tool for damage and wear
u
every 100,000 screw connections at the latest and
check all functions. Then set the torque of the clutch
again.
