4 Notes on particular risks
WARNING
Risk of injury due to sudden movements!
If the energy supply is switched on or if residual energy is still present in the
system, this can cause components to move unexpectedly, which may res-
ult in serious injuries.
• Switch off energy supply and secure against re-connection.
• Ensure that no residual energy remains in the system.
WARNING
Risk of injury due to spring forces!
Products that use spring force or have gripping force maintenance contain
parts that are under spring tension. This can cause components to move un-
expectedly when being dismantled, which may result in serious injuries.
• Carefully dismantle the product.
