• Allow the product to acclimatize for some hours prior to installation, since
otherwise condensed water may be generated.
• Secure the bladder-type accumulator against unintended rolling or falling during
installation in order to avoid any personal injuries or material damage to the
bladder-type accumulator.
• Fasten the bladder-type accumulator safely by means of mounting clamps
according to RE 50170 in order to relieve the pipe union and in order to avoid
loosening or damage due to vibrations.
• Immediately wipe off any oil leaking during installation in order to avoid a slip hazard.
• Make sure that the system is depressurized before charging the bladder-type
accumulator with nitrogen.
• Only charge the bladder-type accumulator with nitrogen 99.99 percent by
volume. If the bladder-type accumulator is charged with different gases -
particularly with air or oxygen -, the bladder-type accumulator might explode.
• Always use the charging and test device according to RE 50170 for charging
the bladder-type accumulator.
• Do not put into operation the product, unless it is completely installed.
• Always observe the operating manual of the machine/system.
• Within the framework of the intended use of the hydraulics system, only authorized
personnel may operate the adjustment elements of components and parts.
• Restrict the access to the direct operating area of the system to persons
authorized by the operator. This is also valid, when the system is at standstill.
• Make sure that the type cap is always installed and legible. Otherwise, further
operation is not allowed.
• In case of an emergency, an error or other irregularities, switch off the system
and secure it against restarting.
• The bladder-type accumulator must not be operated with corrosive fluids.
Otherwise, there is a risk of reduction of the wall thickness and thus a danger of
bursting for the pressure vessel.
• Make sure that no forces are applied to the bladder-type accumulator. The
effects of external forces may lead to damage on the oil connection and the
uncontrolled release of pressurized fluids.
• Make sure that the ambient temperature of the bladder-type accumulator does
not exceed or fall short of the ambient temperature indicated in the technical
data or on the type cap.
• Close the fluid connection and cover the gas port by means of the cover cap
provided.
• Never use solvents or aggressive cleaning agents.
• Only clean the bladder-type accumulator with a dry non-fiber cloth.
• Do not use pressure washers to clean it.
• The operator is obliged to submit the bladder-type accumulator to regular
servicing inspections according to the locally applicable provisions. Check which provisions
or ordinances are to be complied with in your country and/or for your application.
• Repair works on the HAB..-4X bladder-type accumulator must only be carried
out by the manufacturer or by authorized dealers and agencies. If this condition
is not complied with, the warranty expires.
