12. If a cartridge misfires or fails to ignite proceed as
follows:
– Keep the tool pressed against work surface for
30 seconds. During this time, the trigger may be
pulled as often as desired as further attempts to
fire the tool.
– If cartridge still does not ignite, withdraw the
tool from work surface taking care that it is not
pointed at user or bystanders.
– Cycle the tool to transport the next cartridge to
the firing position. Use up the cartridges remain-
ing in the revolvering magazine. Dispose of non-
fired (misfired, live) cartridges in such a way
that they can be neither used again nor misused.
13. Never make a fastening / never drive a stud into
an existing hole or a stud already in place.
14. When fastening to concrete, a steel plate at least
3 mm thick must always be laid on the concrete
surface and the stud then driven through it.
15. Always keep the tool and cartridges locked in a
container and in a safe place when not in use.
16. Do not make fastenings in an explosive or flam-
mable atmosphere, except where the tool is approved
for such use.
17. Always consult the application guidelines.
18. The exceptionally high power of this tool and its
high-velocity working principle make it necessary
for suitable safety precautions to be taken where
the tool is being used. If the tool is used wrongly,
through-shots can occur. Consequently, make sure
that no one is behind or beneath the place, point,
component, etc. where the fastenings are being
made.
Tests conducted to determine the free-flight behav-
iour of the studs showed that a stud will travel at
least 1 m under water and at least 60 m above
water.
All UW 10 users / operators must have received
special training.
19. The applicable national regulations, particularly
those relating to accident prevention, must always
be observed.
5.1 Tool safety devices
Contact pressure safety device / free-flighting safety
device
The tool cannot be fired until the cocking pressure and
the cocking distance have been overcome.
Drop firing safety device
The tool cannot drop fire because of the cocking move-
ment and the firing mechanism.
7° till safety device
If the tool is tilted at an angle of more than 7° when
cocked on the work surface, it cannot be fired.
Spall guard safety device
The tool can only be fired when the spall guard is mount-
ed.
Transport safety
Transport safety feature is integrated into the tool design.
There is only one configuration in which the tool can be
fully cocked and fired. This configuration of tool parts
is indicated by marks which are next to each other.

5.2 Noise information as per German legislation
(3, GSGV dated January 18, 1991):
The noise power level L

as per § 1 (2) 1b) and,
owing to the different places of working depending on
the application, the measuring area noise pressure lev-
el, L
pA, 1S
measured at a distance of 1 m as per § 1 (2)
1e), are given as well as the workplace-related emission
figure according to the measuring standard. Operating
condition and set-up conditions: Heaviest cartridge load
to be used for the purpose with adapted stud, fired into
a concrete block vertically downwards, measuring sys-
tem in accordance with DIN 45635 part 34, “ Measur-
ing noise levels of powder-actuated tools”.
Noise level (above water):
1b) Noise power level
L
WA, 1S
= 136 dB (A)
1e) Measuring area noise pressure level
L
pA, 1S
= 123 dB (A)
1b) Work-place related emission figure
L
pA, 1S
= 125 dB (A)
Different working conditions (particularly working under-
water) can result in other noise emission values.
