12. If necessary, limit the RLL height of the extreme upper position while the implement
uplifting. It is required for the slope angle decrease, for exclusion of cardan shaft touching
and damaging, and for providing safety clearance between the tractor and the implement.
13. Maximum permissible slope and turning angles (figure 4.9.5) of the cardan shaft hinge
joints are shown in table 4.9.

Other variants are possible (see the documentation of cardan shaft and implement
manufacturers).
2)
For short period, for the PTO shaft operating with no load.
3)
For the implement transport position when the PTO shaft is off.
14. While operating with mounted and semi-mounted implements having cardan drive, it is
required to block the lift linkage lower links.
15. After the cardan shaft dismounting, it is required to put guard hoods on the PTO shaft
end extensions and PRS!
16. After the PTO shaft deactivation, consider the hazard of the implement cardan shaft
and separate mechanisms coupled coasting. For this reason the dangerous area between
the tractor and the implement can be entered only after the PTO shaft complete stop!
17. Check the operation of the implement with the cardan shaft mounted to the PTO shaft
and PRS at the minimum and maximum rpm of the tractor engine shaft.
18. While tractor transportation with trailed, semi-trailed and semi-mounted implements for
long distances, including from one field to another, it is recommended to disconnect the
cardan shaft from the tractor and from the implement.
19. Maintenance, cleaning and repair services of the implement with the cardan drive cou-
pled to the tractor shall be carried out only when the PTO shaft and the tractor engine are
off.
The PTO shaft shall be disengaged in the following cases:
- after the tractor stop, only after the coupled implement fully completed its duty cycle;
- on turns, when the implement is lifted to the transport position;
