Maintenance of the milking machine

Demonstration video

Solution name: Maintenance of the milking machine

Aim: Improve the understanding of the different steps to follow in order to properly maintain a milking machine


This video offers a step-by-step explanation on how to maintain a milking machine, which often suffers from a substantial dust deposit. 1st tip: make sure to know how to assemble a piece’s parts back when disassembling it. A solution could be to take photos at each stage of the process.

The video then proceeds with tips related to the vacuum pump. There has to be some oil in the tank constantly, and it needs to be refuelled if necessary.  This shall be checked every week. If the vacuum pump is driven by belts, it is essential to inspect them for damages once a month. To do so, the machine must be shut down and the protective cover removed. Make sure that the belts do not sustain any cracks and that they are perfectly tensioned.

Once a month, someone must make sure that the vacuum regulator’s filters and air inlets are still clean.  Before cleaning it, remove the regulator from the vacuum system. At first, you shall remove the dust from the filter using a brush or a compressor. Verify that all vents are unblocked.

The video then addresses the topic of pulsators. In case of air inlets being directly linked to the atmospheric air, you shall clean the grids or foam materials whose role is to protect the pulsators from the dust. The air pipeline’s filters should also be freed from dust. Both operations must be carried out once a month.

The clusters, some of the milking machine’s crucial parts, must be inspected every day. Calibrated orifices must be unblocked and potential torsions of the liners in the shells corrected.



General: Take photos when disassembling something so as to know how the elements fit together and how to properly re-assemble them,

Everyday: before milking, make sure that all calibrated orifices are unblocked and, if necessary, correct potential torsions of the liner in the shells,

Once a week: check the level of oil from the vacuum pump,

Once a month: Machine shutdown, inspection of the vacuum pump’s belts for anomalies in the tension and presence of cracks, removal of the dust in the vacuum regulator’s filter, removal of the dust in the pulsators’ filters and orifices.


How to implement it: It could be useful to write a calendar down and/or to set up alarms in order to remind you to check on the equipment, especially for monthly checks

Topic: Health / management

Production:  Dairy

Animal Category: Adult 

Issue: Milking management (milking management, handling and available information); Mastitis (clinical and subclinical, high somatic cell count)

Level of Solution: Practical

Country: France






Expected benefits

Expected benefits: It should prevent the udders from being contaminated by cells and also ensure that the milking machine stays efficient in the long run


Prerequisites and/or limits: It is necessary to know where the milking machine’s different parts are located. One may need to seek assistance from his/her machine’s manufacturer or his/her “Milk” advisor during the first maintenance operations.
