Residual risks
Even when adhering to the safety measures mentioned there are residual risks
when using the device:
During maintenance and servicing with switched off air supply the ram can
fall. Therefore, before start of work an appropriate support has to be inserted
into the tool which will be able to carry the maximum press force of the press.
Because the tool will be designed by the customer it is not possible for the
manufacturer to provide a fixture.
Due to longer switch off of the air and power supply it can happen that the
ram falls. When switching on the air and power supply the press moves back
to the top dead center. Therefore, increased caution is necessary when
switching on the control voltage!
The maximum allowable area for mounting tools is defined by the dimen-
sions of the press ram. In this case, the return stroke is safe, i.e. no danger
areas are present during the upward movement of the ram. Tools with bigger
dimensions are only allowable if additional covers (not included in the scope
of delivery) that ensure a safe return stroke are used.
If tools are used that exceed the dimensions of the press stand table, in-
creased caution is necessary and the operator has to make sure that no
crushing hazard is generated between the tool and the C-stand of the press.
This is necessary especially for presses with extended throat stand. Here, no
constructive measure by the manufacturer is possible.
Additional safety measures may be necessary to minimize the exposure of
the operator to hazardous materials which might originate during processing.
Since these materials are not defined the necessary measures cannot be
dealt with in this manual.
Depending on the use of the press additional measures to reduce fire and
explosion hazards as much as possible might be necessary. When using
flammable matters EN 1127-1 indicates guidelines.
