1 Safety instructions
1.1 Basic information concerning safety
In addition to the information relevant to safety given
in each of the sections of these operating instructions,
the following points must be strictly observed at all
times.
1.1.1 Using cartridges
Use only Hilti cartridges or cartridges of equivalent
quality.
Use of cartridges of inferior quality in Hilti tools may lead
to a build-up of unburned powder, which may explode
and cause sever injuries to operators and bystanders.
Cartridges must fulfill one of the following minimum re-
quirements:
a) The applicable manufacturer must be able to verify
successful testing in accordance with the EU stand-
ard EN 16264
or
b) The cartridges must bear the CE conformity mark
(mandatory in the EU as of July 2013).
NOTE
All Hilti cartridges for powder-actuated tools have been
tested successfully in accordance with EN 16264. The
tests defined in the EN 16264 standard are system tests
carried out by the certification authority using specific
combinations of cartridges and tools. The tool designa-
tion, the name of the certification authority and the system
test number are printed on the cartridge packaging.
Please refer to the packaging example at:
www.hilti.com/dx-cartridges
1.1.2 Requirements to be met by users
Never attempt to use the tool without first receiving
proper instruction on its use and observance of the
associated safety precautions.
Contact your local Hilti
representative for assistance.
1.1.3 Personal safety
a)
Stay alert, watch what you are doing and use
common sense when operating a direct fastening
tool. Do not use tool while tired or under the influ-
ence of drugs, alcohol or medication.
A moment of
inattention while operating tools may result in serious
personal injury.
b)
Avoid unfavorable body positions. Make sure you
work from a safe stance and stay in balance at all
times.
