PROFESSIONAL ADVICE

As already mentioned, scheduled periodic maintenance of compressors by regular
mechanics-repairmen at our machine-building enterprises is rarely carried out anywhere. It is
not the repair of the compressor (due to a breakdown), but its scheduled preventive maintenance
(SPM). This attitude to compressors originates from the established principle in our reality: "do
not interfere with the machine to work." In addition, production managers, as a rule, relieve
themselves of the burden of responsibility for organizing the auxiliary equipment SPM, placing
this responsibility on the department of the chief mechanic (DCM) of the enterprise. At the
same time, the above managers do not provide DCM repair specialists with the opportunity to
"approach" the compressors during working hours on weekdays, when they are busy pumping
air for the main production. Only the weekend remains. However, you have to pay for work on
weekends. But paying "overtime" for supposedly "routine" maintenance of ancillary equipment
is something incredible. Moreover, if this equipment seems to be working properly. Well, why
should he "interfere" with this?
Below I present to the readers my version of the periodic maintenance of the SPINN series
compressors, taking into account the requirements of the original guidelines. And, contrary to
our production practice, the main time of work on the compressor application software in the
shown version falls on weekends and holidays. Let the DCM repair specialists not condemn me.
