Changing Application Tools on the Head with
Quick-change Chuck (see figure G)
Inserting
Use only insertion tools with fitting end pieces
(1/4" hexagonal).
– Pull the sleeve of quick-change chuck 23 to the front and
hold.
– Insert tool bit 1 into tool holder 2 and release the quick-
change chuck.
Removing
– Pull the sleeve of quick-change chuck 23 to the front and
hold.
– Remove tool bit 1 from tool holder 2 and release the quick-
change chuck.
Operation
Before any work on the power tool, remove the battery.
Starting Operation
When starting the power tool, you should first select the di-
rection of rotation with the rotational direction switch 9 since
the power tool starts only when the rotational direction switch
9 is not in the middle position (switch-on lock).
Reversing the rotational direction (see figure H)
– Right rotation: For driving in screws, push the rotational
direction switch 9 left to the stop.
– Left Rotation: For loosening or unscrewing screws, push
the rotational direction switch 9 right to the stop.
Switching On the Worklight
The work area illumination 6 makes possible the lighting of
the screwing position for unfavorable light conditions. The
work area illumination 6 is switched on by lightly pressing the
on/off switch 8. When the on/off switch is firmly pressed, the
power tool is switched on and the work area illumination con-
tinues to light.
Do not look directly into the work area illumination –
your sight can be temporarily degraded!
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 8 to the stop.
– The machine switches off automatically as soon as the
preset torque is reached.
When the on/off switch 8 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 figure I)
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 24 provided.
– Push the torque selector switch 7 on the power tool com-
pletely back.
– Insert a hex key 25 into tool bit 1 and turn it slowly.
– When a small indentation (adjusting dial 26) is visible in
the clutch, insert the adjustment tool 24 into the indenta-
tion and turn it.
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 J)
Always use the power tool with a marking ring to insure that
the housing body is sealed from dust and dirt.
To identify individually adjusted tightening torques, the mark-
ing ring 18 an be replaced with a marking ring of another color.
– Press off the marking ring 18 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 11 lights green.
If the preset torque is not reached, the LED indicator 11 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.
