10) set the required air pressure in tyres.
The standard values of operating modes of the tyre shall correspond to Tables 3 and 4.
Maintain record-
keeping for each tyre separately. To this end, a “Tyre operation registration
card” is to be established (Appendix 8), which is the main document characterizing the tyre
operation in case of reclamation, write-off to scrap as well as in other cases. The internal
pressure in tyres should be registered in the “Log-book for registration of measurements of the
internal air pressure in tyres” (Appendix 7).
The pressure measurement is carried out once in every five days before tractor travelling for
work execution. The results are registered in the log-book.

Note. At the speed of no more than 16 km/h it is allowed to increase the
load on tyre up to 20% without increase of the internal pressure.
