0 - 26 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.
