Check the fill valve for leaks (e.g. with foaming agents). Always use the protective caps to protect
the fill valve.
8.3 Hydraulic pressure systems
First, the precharging pressure P
0
must be checked. Check the hydraulic pressure system
regarding leaks.
Make sure that the hydrostatic pressure displayed on the hydro accumulator the maximum
allowable pressure PS does not exceed.
The pressure system can be vented on the fluid valve of the hydro accumulator at some models.
After venting, the vent screw must be closed and to be checked for tightness and leaks.
Caution! Never open the bleed screw when the hydraulic system is under pressure.
9. Maintenance / Repair
The maintenance and repair of the bladder accumulator requires basic mechanical and
hydraulic knowledge. The maintenance and repair of the hydro accumulator may only be
carried out by qualified staffs.
Before the hydraulic accumulator is dismantled by the system, it must be ensured that the
hydraulic accumulator is completely depressurized on the liquid- and system side.
Disassembly, assembly and repair of the hydro accumulator may only be carried out by
the manufacturer or authorized persons. For self-made repairs no guarantee is assumed!
For transport, close all openings with suitable protective caps so that dirt or moisture can
not penetrate into the bladder accumulator.
Make sure that all connecting parts, in particular pressurized connecting parts, are
sufficiently fixed. Self-loosing parts can lead to property damage and personal injury.
Before the dismantling of the hydraulic accumulator, please ensure that the accumulator on the
liquid side is fully pressureless and released.
Before the dismantling of the accumulator all externally mounted components must be removed
on liquid side such as reducers and other accessories.
If the accumulator is completely relieved (gas and liquid side) the liquid valve must
be open. If this can not be determined, further work is not permitted!
