When it comes to unscrewing the grinder's disks on the farm, many owners find themselves in an extremely unpleasant situation. It turns out that this is not so difficult to do. Often the problem lies in the banal lack of relevant knowledge and skills in this regard. The fact is that the process is much more tricky than it might seem. What you need to know in order to simplify your task as much as possible.
The problem lies in the clamping nut for the grinder. In the vast majority of cases, it is too tight and inconvenient to work with. This is needed mainly in order to ensure the safety of the worker and those who may be with him. However, because of this, any disk replacement turns into a "quest". Nobody wants to suffer with a nut every time they change a disc. Experienced craftsmen know what needs to be done in order to forget about such problems once and for all.
So, firstly, when working with the clamping nut, you must use a lubricant. Any silicone grease works best. The nut is carefully processed before unscrewing it and left in this state for 5-7 minutes. When the waiting period expires, it will be several times easier to unscrew the fixing element of the structure.

Secondly, while the nut is removed, there is one more thing to do with it. It is necessary to sharpen its two sides by 1.5-2 mm. This can be done with a file. The most important thing in this matter is not to overdo it. So we work slowly and very carefully. This must be done in order to facilitate the subsequent procedures for tightening and unscrewing the nut. After the upgrade, it will be possible to use a regular 36 key for this purpose.
