Maintenance
The machine and the entire system must be inspected and maintained at regular intervals. The time
limit for maintenance is set by the manufacturer and applies to the general conditions of use. The
manufacturer should be consulted if the system is to be used with corrosive and/or abrasive
pumped liquids, as the time limit between inspections may need to be reduced.
Note the following information:
- The operating and maintenance manual must be available to the maintenance personnel and
its instructions followed. Only the repair and maintenance measures listed here may be per-
formed.
- All maintenance, inspection and cleaning work on the machine and the system may only be
carried out by trained specialists exercising extreme care in a safe workplace. Proper protec-
tive clothing is to be worn. The machine must be disconnected from the electricity supply
before any work is carried out. There must be no way that it can be inadvertently switched on.
Additionally, the appropriate protective measures as defined by the BGV/GNV should be
enforced when working in basins and/or containers.
- Above a weight of 50kg, only hoisting gear which has been officially approved and which is in
a technically perfect condition should be used for lowering and raising the machine.
Make sure that all fastening devices, ropes and safety devices of the
hand winch are in a technically perfect condition. Work may only com-
mence if the auxiliary hoisting gear has been checked and found to be in
perfect working order. If it is not inspected, danger to personnel may
result.
- Electrical work on the machine and system must be carried out by an electrician. For machines
approved for work in areas subject to explosion danger, please refer to the “Explosion protec-
tion in accordance with the .... regulation” chapter. Defective fuses must be replaced. Under
no circumstances are they to be repaired. Only fuses at the specified current and of the pre-
scribed type may be used.
- When working with inflammable solvents and cleaning agents, fires, unshielded lighting and
smoking are prohibited.
- Machines which circulate fluids hazardous to health, or which come into contact with them,
must be decontaminated. It must be ensured that no dangerous gases can form or are
present.
If injuries involving hazardous pumping liquids or gases occur, first-aid
measures must be performed in accordance with the notices in the
workplace and a doctor should be called immediately.
- Ensure that all necessary tools and materials are available. Tidiness and cleanliness guarantee
safe and problem-free operation of the machine. After working on the machine all cleaning
materials and tools should be removed from it. All materials and tools should be stored in an
appropriate place.
- Operating supplies such as oil and lubricants must be collected in appropriate vessels and
properly disposed of (in accordance with the 75/439/EEC directive and with §§5a, 5b AbfG).
Appropriate protective clothing is to be worn for cleaning and maintenance jobs. This is to be
disposed of in accordance with waste code TA 524 02 and EC Directive 91/689/EEC. Only
lubricants expressly recommended by the manufacturer may be used. Oils and lubricants
should not be mixed. Only use genuine parts made by the manufacturer.
A trial run or functional test of the machine must be performed as
instructed in the general operating conditions.
