Surface and distances
Caution
Pins may not be driven in unsuitable materials or
components.
Recommended basis
Test the strength of the surface. The minimum pen-
etration depth of the driving pin and the minimum
strength of the surface must be maintained. This
ensures secure hold of the fastening connection.

Minimum distance of the basis from cen-
tres and edges (see also the provisions
of the German BGV D9 2002)
The distance to free edges must be sufficient to
prevent the pin from lateral penetration.
Do not drive in the pins too close in order to prevent
them from comming loose from their fixing position
in case the material breakes out or tears away.

Handling (fig. V)
Firing a pin
■
Hold the device firmly and stand in a stable
position.
■
Position the device rectangular to the material
surface. The sleeve
[13]
and the magazine foot
[9]
must rest securely on the surface.
■
Press the device with the sleeve
[13]
against the
material surface.
3
This releases the safety of the device. The fan
motor is switched on and draws in air. Gas is
injected in the combustion chamber.
Caution
Never hold your hand directly in front of the intake
opening since this may cause malfunctions!
■
Press the actuator.
3
The gas mix is ignited electrically and the pin is
driven into the basis.
Note
Ignition is only initiated if the sleeve
[13]
is completely pushed in and if at
least three pins are in the magazine.
■
Release the trigger and remove the device.
3
The exhaust gas is discharged via the openings
[14]
. Simultaneously fresh air is blown in the
combustion chamber.
Note
If no further pin is driven in, the fan
continues blowing for approx. eight
seconds and is then switched off.
Warning
The device is designed for continuous
operation. In this process, the sleeve
can get very hot.
If you detect visible defects, immediately stop work-
ing with the device and have it repaired by Würth.
Driving depth adjustment
Danger
For safety reasons always remove the
battery and the gas cartridge from the
device prior to adjusting works!
Warning
The adjustment dial can get very hot
during operation.
The driving depth can be adjusted, if required, and
can be set by the adjustment dial
[17]
.
■
Perform a test by driving a pin into the material.
■
Turn the adjustment dial
[17]
according to the
displayed mark.
