Maintenance at a glance

The background and goals

Maintenance is understood to mean all measures that serve both to record the current status quo as well as to assess machines, systems or networks and which are able to maintain or restore the target status. Plant safety is also an important area of ​​maintenance.

Maintenance is of essential importance, because without maintenance activities, for example, safe, smooth, trouble-free, reliable and efficient operation cannot be guaranteed in the long term.

Maintaining and optimizing the functionality and service life of all machines, systems or processes is of great importance. Because regular maintenance can improve operational safety on the one hand, and processes can be monitored and optimized on the other. System failures, which can lead to massive losses in industry, can not only be reduced by maintenance, but often even avoided. With the regular recording of the current situation, it is possible to recognize disruptions at an early stage, to take suitable countermeasures in good time and to plan any expenses that may arise.

In simple terms, maintaining a healthy lifestyle with regular medical check-ups. Prevention is better than reaction.

5 elements of maintenance

1. Inspection

The inspection is used to record the condition and function control. During an inspection, it can be seen whether maintenance measures are required that can avoid subsequent repairs.
Maintenance made easy.

2. Maintenance

Maintenance is used for prevention in order to prevent signs of wear and tear. This includes the cleaning of machines, the refilling of operating fluids and lubricants as well as readjustment.

3. Elimination of malfunctions

Faults in individual elements can be eliminated by repairs in order to maintain efficiency and productivity and prevent failures.

4. Repair

The repair itself is only used if defects have occurred despite inspection, maintenance and troubleshooting. Wearing parts are exchanged, defective components replaced or repaired. The functionality is preserved.

5. Optimization

The optimization serves to increase safety, productivity and reliability and ensures that systems and machines can be used in the best possible way.



The term maintenance is standardized according to DIN31051 and serves to maintain functionality. Maintenance also includes the repair or optimization of individual components in order to enable the entire system to function properly. All analytical, technical and administrative measures of a machine system are summarized under the term maintenance.


The inspection, on the other hand, describes measures that record the current state of a system and then assess it. If there is a need for optimization during the inspection, implementation is then carried out to improve and repair the system accordingly. The aim is always to achieve the best possible result in terms of efficiency and production.

The inspection, which is used as a basic measure, includes the inspection. While the system is in operation, the inspector inspects the functionality and checks the individual segments of the system. Control via drones has already established itself in large-scale systems; this form of mobile maintenance is used to control devices and machines that are difficult to reach. The next step consists of a visual inspection, during which existing functional deficiencies are recorded via visual assessment. The subsequent functional test determines whether the system is suitable for performing its actual function. Any defects are documented in writing and recorded for improvement.


Maintenance is the most important element in maintaining functionality. It is used to identify errors in good time and to prevent them. For example, the use of lubricants can prevent future defects in the system. If there are already defects, the repair is used. It is used to return the system to the required state. If the object is defective, repairs must be carried out that go far beyond maintenance.


With CMMS, i.e. a software-supported maintenance management system such as MAIN-TOOL, it is not only possible to document the work steps carried out (who, where, when, what), but also to record the results of the maintenance activity, categorize them for evaluation purposes and, if necessary, directly Recurring maintenance processes are predestined for software-supported optimization of processes. The aim is to minimize the effort required to set up and configure the application, while still generating permanently usable added value.

This concerns both the increase in the utilization of the company through more structured and more targeted maintenance activities per se as well as the saving of resources for the organization, implementation and documentation of the maintenance through software-supported processes. These maintenance management systems (CMMS) bundle information, bring together divergent communication and documentation levels and then make the required information available transparently on various work platforms.

In contrast to the CMMS, asset management, such as a corporate asset management system (EAM), enables assets (tangible assets) and parts of a company’s current assets to be recorded and managed. By combining both systems, CMMS and EAM, the company management is able to combine key figures from both systems and evaluate them in combination, which enables a detailed insight into the company’s processes.


Maintenance is an important part of optimizing and maintaining the performance capacity of any company. The timely detection of potential sources of error and the maintenance and care of your technical systems mean that failures and malfunctions can be efficiently avoided. This permanently increases the availability. Malfunctions can mean considerable losses for companies of all kinds, because unplanned repairs take up more time than regular maintenance.

Inconsistent communication and documentation media with information exchange by telephone, handwritten notes, e-mails, maintenance instructions in paper form or as PDF and if necessary. Partial database solutions ensure that maintenance and servicing take up a lot of human resources and thus result in a loss of efficiency. With software-based, mobile maintenance solutions it is not only possible to save time, but also to use resources more efficiently.

Software-supported maintenance not only enables an increase in the utilization of the company through structured and targeted maintenance activities of the monitored objects, but also generates day Noticeable added value every day through the more efficient use of resources for the organization, implementation and documentation of maintenance.

MAIN-TOOL is equipped with a very extensive range of functions, with which most customer requirements are covered in the standard.
