SAFETY INSTRUCTIONS 

WX210 - WX240

 

 

 

 

Prestressed units 

Safety instructions for accumulators 

 

 

Never open defective prestressed 
systems but replace the entire sys-
tem. 

Open only in exceptional cases, 
when the system and the opera-
tional sequence are exactly known 
and the necessary special tools are 
available. 

Accumulators are installed in the 
hydraulic system. They contain ni-
trogen under high initial pressure. 

Even when the hydraulic system 
has been depressurized, the nitro-
gen pressure is maintained in the 
accumulator. 

The accumulators are completely 
safe in operation. If incorrectly han-
dled, however, there is a risk of ex-
plosion. 

The accumulators installed in this 
machine cannot be repaired. Defec-
tive accumulators must be replaced. 

Never handle accumulators me-
chanically, never weld or solder 
them. 

Before dismantling the accumulator, 
put on goggles and working gloves, 
and depressurize the hydraulic sys-
tem. 

Use original spares only. If in doubt, 
contact your local agent or the after-
sales service.  

Never remove or paint over warning 
and information plates, rating plates 
or type identification markings. Re-
place illegible or damaged plates 
immediately. 

 

Never remove lead seals 

 

Never change the rated pressure of 
pressure-reducing valves without 
the explicit authorization of the 
manufacturer. 

Never remove lead seals from pres-
sure-reducing valves and accumula-
tors.
