suddenly blocks in high pressure

Hydraulic block

Dirty filters

Perform reset procedure

Replace filters

High pressure variations during
commutation
(> 0,2 Bar)

Low pressure in the accumulator

Load at a pressure of about 4 bar

Low production / normal or low
pressure

Low battery

Air within the system

Check battery charge

Purge air by opening for a while
the pressure valve

Low production / high pressure
(> 9 Bar)

Clogged filters
