Page 3: Function
The coupling must only be operated in normal industrial atmospheres. Since aggressive media may attack the coupling components, screws and elastic buffer rings, they represent a risk for the operational safety of the coupling. Consult RINGFEDER POWER TRANSMISSION in such cases. -
Page 4: Marking Of The Coupling
The coupling parts can be stored in their delivered standard-state for 6 months in a dry, roofed place at normal room temperature. For a longer storage duration a long-term preser- vation is necessary (consult RINGFEDER POWER TRANSMISSION). The elastic intermediate ring must not be subjected to ozone containing mediums, direct solar influence or strong light sources with ultraviolet-light. -

Page 15: Operation
When using the coupling attention is to be paid to its characteristics (see „6 Technical data”). These can in no case be exceeded without having a written agreement from RINGFEDER POWER TRANSMISSION. In order to guarantee a faultless, lasting operation of the coupling, it must be laid out accord-ing to the regulations e.g. - Page 16 Alignment fault Considerable Disconnect drive wear of increase in Remove cause for alignment fault elastomer coupling tempera- Re-align coupling ture.
