Principle safety instructions
Carry out the maintenance works prescribed at the intervals stipulated in the
•
operating manual of the entire system. If no other instructions are given, we
recommend maintenance intervals according to chapter 9.1 “Maintenance”.
Make sure that the hose lines, connections and components are not loosened as long
•
as the system is pressurized and energized or that the bladder-type accumulator is
not still under hydraulic pressure. Secure the system against restarting.
Secure the bladder-type accumulator against unintended falling or rolling.
•
For the discharging of the bladder-type accumulator, always use the charging
•
and test device according to RE 50170. The uncontrolled release of charging gas
results in a risk of suffocation and a risk of injury due to entrained components.
During discharge, make sure that the working space is sufficiently ventilated.
Always use the charging and test device according to RE 50170 for the
•
charging of the bladder-type accumulator.
Only charge the bladder-type accumulator with nitrogen 99.99 percent by
•
volume. If the bladder-type accumulator is charged with a gas not complying
with the intended use, the bladder-type accumulator might explode.
After the servicing works are completed, make sure that the fluid connection is
•
correctly connected again and the gas port is covered.
•
Make sure that the hose lines, connections and components are not loosened
as long as the system is pressurized and energized or that the bladder-type
accumulator is not still under hydraulic pressure. Secure the system against
restarting.
For the discharging of the bladder-type accumulator, always use the charging
•
and test device according to RE 50170. The uncontrolled release of charging gas
results in a risk of suffocation and a risk of injury due to entrained components.
During discharge, make sure that the working space is sufficiently ventilated.
When bladder-type accumulators with a capacity of 10 l or more are
•
disassembled, there is a risk of personal injuries due to their weight. Use
appropriate lifting gear for the disassembly of bladder-type accumulators.
Put down the bladder-type accumulator safely and secure it against unintended
•
rolling or falling in order to avoid any injuries or damage.
If a bladder-type accumulator can no longer be used, make the housing
•
unserviceable by drilling through the vessel wall in the cylindrical area in order
to thus avoid that the pressure vessel be reused.
•
Dispose of the hydraulic fluid according to the provisions valid in your country
as well as according to the safety data sheets of the hydraulic fluids.
