Description3
General Product Description3.1
The Power Drive F35 Stud Driver is a safe tool that can be employed for a wide
range of applications by professional, certied users.
The tool is intended for commercial use for xing purposes by driving elements of
the scher accessories product range developed specially for this eld of applica-
tion into concrete, steel, solid brick and solid lime-sand brick.
Only scher safety cartridges FSC 6.8 /11 (0.27 inch) may be used to generate the
propulsion gas. Fastening is performed directly through the part to be xed into the
anchoring substrate (base material). Predrilling of holes is not necessary.
The Stud Driver has a 6-position power regulator that allows the tool power to be
optimally adapted to the intended application.
The low noise and minimum recoil increase the comfort for the operator and thus
contribute signicantly to higher productivity. The powder-driven system is com-
pletely portable so that it can be used even in conned spaces and at points with
restricted access.

Description3
The Functional Principle3.4
The tool functions on the basis of the piston principle. This technique ensures opti-
mum working safety and reliable xing solutions. In view of its design, the tool is a
Class A Stud Driver in accordance with the German Firearms Act.
The Power Drive F35 Stud Driver operates on the indirect action principle. The ring
of the cartridge creates a positive pressure in the combustion chamber. The posi-
tive pressure acts on the contained piston and is transformed into motion energy
(kinetic energy). The piston transmits this kinetic energy directly to the fastener
element (stud) inserted into the fastener guide, thus permitting a controlled penetra-
tion into the base material.
This principle allows the velocity of the fastener element (stud) to be reduced to less
than 100 m/s, thus giving the system a very high degree of safety.
There is no risk of ricochets, as the piston is contained in the Stud Driver and the
driven fastener element (stud) is thus prevented from becoming a projectile.
During reloading of the Stud Driver, the piston is moved back to its starting position
(loading process). The cartridge strip is advanced at the same time. This enables
quick, inexpensive and safe working for the operator.
Safety Devices3.5
Drop protection
A possible ignition of the ring charge is prevented mechanically if the Stud Driver
collides with a hard surface.
Contact protection
The Stud Driver must be pressed with the fastener element opening completely
against the substrate before a stud can be driven.
Trigger protection
Simply pressing the trigger does not ignite the ring charge.
Firing protection
If the Stud Driver is pressed with the fastener element opening completely against
the substrate with the trigger already pressed, the ring charge is not ignited.

13
Before Starting Work4
Before working with the Stud Driver, it is essential that you familiarise yourself with
the characteristics of the base material and of the fastener elements. The materials
into which the fastener elements are to be driven must be analysed. The fastener
elements, the cartridge and the setting of the 6-position power regulator are then
selected on the basis of this analysis.
Analysis of the Base Material4.1
For the work with the Stud Driver it is necessary to determine the characteristics
of the base material into which the fastener element is to be driven by means of a
penetration test.
Try to drive the fastener element into the base material using a hammer. The
˚
base material is
too soft – if the fastener element penetrates easily into the base material,
too hard – if the fastener element becomes blunt,
too brittle – if it breaks or cracks,
suitable – if the fastener element remains sharp and leaves a deformation in the
base material.
Selection of Appropriate Cartridge4.2
The cartridges are distinguished according to their power classes and are corre-
spondingly colour coded (see chapter 8.1).
Always test a fastener element rst with cartridges of the lowest power class when
working with a new base material. If the fastener element does not achieve the
necessary penetration depth, try with the next higher power class until the required
penetration depth is reached.
Selection of Appropriate Fastener Elements4.3
Fixing in concrete
Eective anchoring depth (hef)
For xtures in concrete, the eective anchoring depth (hef) is the determining factor
for the selection of the appropriate fastener element. The eective anchoring depth
(hef) is dependent on the compressive strength of the concrete.
Compressive strength of concrete Eective anchoring depth (hef)
C16/20 30 - 35 mm *
C20/25 25 - 30 mm *
C30/37 20 - 25 mm *
The values shown are indicative values. Several test xings should be carried out in the base material to determine the exact values *
for the installation situation.

14
Before Starting Work4
Correct shaft length of the fastener element
The correct shaft length (L) is determined by the thickness of the part to be xed
(tx) and the eective anchoring depth (hef) using the following formula:
h
ef
t
fix
L = tx + hef
For xtures with stud bolts, the necessary shaft length corresponds to the eective
anchoring depth (hef), the thickness of the part to be xed (tx) does not have to be
taken into consideration.
Fixing in steel
Eective anchoring depth (hef)
For xtures in steel, the eective anchoring depth (hef) is the determining factor for
the selection of the appropriate fastener element. The eective anchoring depth (hef)
is dependent on the tensile strength of the steel.
Tensile strength of the steel (fuk) Eective anchoring depth (hef)
360 N/mm² 12 mm
510 N/mm² 10 mm
The values shown are indicative values. Several test xings should be carried out in the base material to determine the exact values *
for the installation situation.
Correct shaft length of the fastener element
The correct shaft length (L) is determined by the thickness of the part to be xed
(tx) and the eective anchoring depth (hef). If proper penetration of the base mate-
rial is desired, an allowance of 6 mm must be made (see following formulae).
Correct shaft length without penetration of the base material:
L = tx + hef
Correct shaft length with proper penetration of the base material:
L = tx + hef + 6 mm
For xtures with stud bolts, the necessary shaft length corresponds to the eective
anchoring depth (hef) plus 6 mm allowance, the thickness of the part to be xed (tx)
does not have to be taken into consideration.
L = hef + 6 mm

Before Starting Work4
Guidelines for Fastening4.4
The guidelines described below must be observed for xtures in dierent base
materials.
General
Do not drive fastener elements into cast iron, aerated concrete, thin sheet metal ˚
(< 4 mm), ceramic tiles, hollow bricks, insulating materials, rock, copper, brass,
bronze, plastic, marble or glass. These materials can splinter.
Do not drive fastener elements into thin or easily penetrated material that is not
˚
backed by concrete, solid brick or steel (xing of plasterboard or insulating pan-
els). If the base material is completely covered and therefore not visible, ensure
for safety reasons that there is a suitable base material before driving each stud
(see chapter 4.1).
DANGER!
Openings and recesses in the base material that are covered by parts to be xed and
that are therefore invisible to the operator pose a particular risk.
Check the base materials by means of a penetration test (see chapter 4.1) before ▸
driving each stud.
Concrete
The following guidelines apply for the installation of fastener elements in concrete.
Minimum base material thickness (hmin)
h
