Warning
Don't carry out welding, soldering or any other mechani-
cal work at the accumulator tank!
– Risk of explosion in welding and soldering works!
– Danger of bursting and loss of the operating
license in case of mechanical processing!
Don't charge hydraulic accumulators with
oxygen or air. Risk of explosion!
Before working at hydraulic systems, depressurize the sys-
tem and secure it against re-activation.
Improper assembly may cause serious injuries!
The commissioning may only be performed by qualified spe-
cialists.
Hydraulic accumulators are pressure vessels and subject to
the application national provisions and/or regulations valid at
