Safety instructions
1.3 General working safety
Improper operation of the machine can lead to personal injury, damage to the machine and
interruptions to the production process.
The management responsible must therefore ensure that operating personnel are properly
trained and that only qualified and authorised personnel work on machine.
1.4 Operation
Operators must be thoroughly trained in handling the machine and its processes.
SAFETY LOCKING DEVICES
Mechanical and electrical safety devices located on the cover and in the discharging
and emptying area prevent anyone from reaching into the machine while it is run-
ning. These safety devices must under no circumstances be made inoperative.
OILS, LUBRICANTS AND COOLANTS
Some of these agents endanger personal health and the environment. Only materi-
als recognised as being physiologically safe should be used. Selection and use of
these materials depends entirely on the management, although STEPHAN can
make recommendations with respect to the materials used.
PRESSURE VESSEL REGULATIONS
If pressure vessels are installed, they are subject to regular inspections according to
the pressure vessel regulations. If necessary, the vessel may need to be tested in
the location where the machine is to be installed. All inspection certificates must be
stored carefully. All working and inspection instructions in the pressure vessel regu-
lations must be observed.
SAFETY VALVE
If the STEPHAN machine works with overpressure, the safety valve is protected in
the works so that the permissible pressure cannot be exceeded. The valve is fitted
with a lead seal so that the release pressure cannot be adjusted. Manipulating the
valve can lead to fatal injuries. Removal of the lead seal also invalidates the guar-
antee.Material drained from the safety valve must be disposed of properly and safe-
ly.
SAFETY AWARENESS
- Management must ensure that operating and maintenance personnel are thor-
oughly acquainted with all safety instructions and that all safety instructions are ac-
tually observed. The operating instructions should be readily available for reference
in the workplace.
- All working procedures which reduce safety at the machine must be avoided.
- Operators are obliged to announce at once every alteration to the machine which
reduces its safety.
- The machine's safety can be reduced by:
* reconfiguration or alteration of the machine
* use of accessories other than those provided by STEPHAN- use of non-original re-
placement and wearing parts
CONCEALED KNIVES, CUTTING RINGS, FEED SCREWS, ETC.
Do not reach into full or partially full machine bowls or funnels, as there is risk of in-
jury from concealed sharp-edged cutting tools and machine parts.
