The trigger lock, which is connected with the movable tacker
head 1, prevents unintentional shot actuation when the trig-
ger 4 is inadvertently pressed.
To save energy, only switch the power tool on when using it.
Starting and Stopping (Single actuation)
– At first, firmly place the tacker head 1 against the work-
piece until it is pushed in a few millimeters. Afterwards,
briefly press the trigger 4 and then release again.
Starting and Stopping (Contact actuation)
– For rapid working, keep the trigger 4 pressed. Position the
machine and press the tacker head 1 firmly against the
workpiece until the shot is actuated. After the shot, move
the tacker to the next location and press the tacker head 1
firmly onto the workpiece again.
DuoTac-Automatic
In DuoTac-Automatic mode, 2 staples are fastened at the
same time. The double staple thickness increases the tear
strength of thin materials, such as fabrics or foils.
The DuoTac function is not possible for processing nails.
– To process 2 staples at the same time, push the DuoTac-
Automatic selector switch 2 up. To process a single staple
or one nail, push the DuoTac-Automatic selector switch 2
down.
Hammer-force Preselection
With the thumbwheel for hammer-force preselection 5, it is
possible to preselect the required hammer force in steps.
The required hammer force depends on the length of the sta-
ples or nails, and on the strength of the material.
When processing 2 staples (DuoTac function), the hammer-
force preselection must be selected approx. one step higher
with thumbwheel 5.
Note: Always test the selected hammer force on scrap mate-
rial first. The optimum hammer-force setting can be deter-
mined only by trial and error.

Working Advice
 This machine is not suitable for working with 19 mm
staples. Therefore, do not use the machine to fasten
ceiling panelling with profiled wood or grooves.
Avoid blank shots in order to reduce the wear of the impact
striker. After finishing your work, set the hammer force with
the thumbwheel for hammer-force preselection 5 to a low val-
ue, in order to relieve the tension spring.
The power tool is designed for short-time duty and will heat up
during continuous operation. Performance will decrease the
more the tool heats up. Duty rating S2 denotes short-time
duty with a maximum operating duration of 10 mins under
constant load. Switch the power tool off after this time and
leave it to cool down.
Removing jammed staples
 Before any work on the machine itself, pull the mains
plug.
– Turn the power tool around.
– Press release buttons 6 and pull out the magazine 9 toward
the rear.
– Remove the jammed staple. For this, use a pair of pliers, if
required.
– Insert the magazine 9 again until it engages.
 Load the magazine in good time. If the staple strip is too
short, this may cause staples to jam.
