Special Work

Organizational
The maintenance work and intervals are specified in the operating manual, including information about
replacing parts/partial equipment.
Maintenance and repair work may be performed only under supervision, or by a person qualified for this
work.
Secure an ample working area, if needed.
Workshop equipment suitable for the work is absolutely required to perform maintenance and repair work.
Safety measures
Personnel must not wear open, long hair, loose clothing, or jewelry, including rings. When the compressor
is running, there is an injury hazard, such as due to jamming or drawing in. If needed or required by
regulations, use personal protective equipment!
Perform only those maintenance and repair works for which you have sufficient training and where you
feel comfortably sure of your ability.
Do not use machine parts as climbing aids. For maintenance work at greater heights, use fall protection.
Maintenance / Fault Clearing
Perform any maintenance and repair work only when the compressor is switched off and the power grid
supply is disconnected. Secure the compressor against being turned on accidentally.
Before opening the compressor enclosure:

Allow the compressor to come to a stop.

Wait for automatic pressure relief.

Wait until the residual energy from the capacitors has dissipated.

Cool the compressor down to room temperature.
Cleanliness
Always pay attention to cleanliness during maintenance and repair work. Keep dirt away by covering
parts and exposed openings with a clean cloth, paper, or tape.
Oil loss causes the floor to be slippery. Clean the work area thoroughly after completing the
maintenance and repair work.
Cleaning agents
Never use solvents or cleaning agents that can corrode the materials to clean the parts.
Take preventive action against vapors of solvents or cleaning agents that are hazardous to health.
Weight / Lifting Gear
Carefully attach and secure heavy individual components and assemblies when replacing, so that
they do not present a hazard. Use only suitable lifting gear that is in technically perfect condition, and
a load handling device with sufficient load capacity. Do not stand or work beneath suspended loads.
Spare parts
Use only original spare parts.
Spare parts must comply with the technical requirements stipulated by the manufacturer. This is
guaranteed only when original spare parts are used.
After completing maintenance and repair work
After maintenance and repair work is completed, ensure that no tools, loose parts, or rags have been
left behind in the compressor (particularly in the drive motor or the drivetrain).
Rotate the drive several times in order to make sure that there is no mechanical fault in the
compressor or the drivetrain.
Tighten all bolt connections that were loosened for the maintenance and repair work. Also check all
the other bolt connections.
