Do not use this to pneumatic tool to fasten electrical
wiring. It is not suitable for fastening electrical wiring,
can damage the insulation of electric cables and thus
lead to electric shock and danger of fire.
Never use oxygen or flammable gases as the energy
source for the pneumatic tool. Flammable gases are
dangerous and can cause the pneumatic tool to ex-
plode.
Use appropriate detectors to determine if utility
lines are hidden in the work area or call the local util-
ity company for assistance. Contact with electric lines
can lead to fire and electric shock. Damaging a gas line
can lead to explosion. Penetrating a water line causes
property damage.
The pneumatic tool may only be connected to lines,
for which the maximal permissible pressure of the
pneumatic tool cannot be exceeded by more than
10 %; for higher pressures, a pressure control valve
(pressure reducer) with preceding pressure-limita-
tion valve in the compressed-air line must be in-
stalled. Excessive pressure leads to abnormal opera-
tion or breakage of the pneumatic tool, which can lead
to injury.

Assembly
Connecting the Air Supply (see figure A)
Make sure that the pressure of the compressed-air system
is below the maximum permitted rated pressure of the
pneumatic tool. Firstly, set the air pressure to the lower
value of the recommended rated pressure (see "Technical
Data").
When in doubt, check the pressure at the air inlet with a
pressure gauge with the pneumatic tool switched on.
For maximum performance, the values for the supply-air
hose 17 (connection thread, maximum operating pres-
sure, inner hose diameter, maximum hose length; see
"Technical Data") must be observed.
The compressed air supplied should be free of foreign ma-
terial and moisture to protect the tool from damage, con-
tamination, and the formation of rust.
All fittings, connecting lines and hoses must be dimen-
sioned for the pressure and the required air volume.
Avoid restrictions in the air supply, e.g., from pinching,
kinking, or stretching!
