9 Maintenance of the Machine
9.1 Inspection and Maintenance Intervals
The following list for regular maintenance gives an overview of the minimum
scope of works required to ensure trouble-free operation. It depends on the
respective operating conditions and the wear of the machine whether and to
what extent further care and maintenance is required.
Maintenance work may only be carried out by technically trained personnel
under careful observance of all necessary accident prevention regulations. It is
also essential to observe the information in section 7.3 Measures before
maintenance and repair on the page 54.
The following general inspection and maintenance work must be carried out in
compliance with the safety regulations at regular intervals (daily if necessary)
depending on the operating conditions or during maintenance work on the
machine:
All external machine areas and components must be cleaned regularly from
dust and dirt.
In particular, the machine area where swarf is produced, must be cleaned
regularly. To do this, the swarf can be removed by hand brush.
Regularly check the cutters used for wear and replace if necessary (see the
documentation of the manufacturer).
The parts of the machine that are not easy to access should be carefully
cleaned with compressed air, possibly with a bellows.
(Vacuuming is better, but not always practicable).
All connection screws must be checked for tightness. All connection termi-
nals for the control lines on devices and terminal strips must also be
checked.
The function of all lamps of the control panel and the drilling light must also
be checked (see the documentation of the manufacturer).
An important measure is the examination of the protection system.
It must be carried out in accordance with VDE regulation 0100 or compara-
ble national regulations.
All monitoring equipment must be checked for responsiveness.
All safety devices must be checked for responsiveness.
The bearings of the drive motor must be maintained according to the oper-
ating manual (see the documentation of the manufacturer).
If cooling air is sucked in through filters, the filter must be cleaned or re-
placed if necessary (see the documentation of the manufacturer).
All warning and information signs must be checked for completeness and
cleanliness, if necessary replaced or cleaned.
