10. If the tractor and the implement coupled are positioned linearly when the cardan
shaft is pushed in full, check if there is a sufficient clearance L
1
(Figure 5.6.4, view C) be-
tween tube face and universal joint yoke end butt. Minimum permissible clearance L
1
shall
make not less than 50 mm.
11. After the cardan shaft coupling regularize all the protective devices, meanwhile
fix the guard shaft housing from rotation with the chains as indicated in Figure 5.6.3.
12. Limit the RLL lifting to the uppermost position along with the implement lifting
when needed. It is essential for slope angle decrease, for exclusion of possibility of contact
and damage of the cardan shaft, and for providing of safety clearance between the tractor
and the implement.
13. After the cardan shaft dismounting it is necessary to put guard hoods on the PTO
shaft end extensions and PRS!
14. After the PTO shaft is disabled consider the hazard of the cardan shaft and indi-
vidual mechanisms of the implement coupled coasting. Therefore the dangerous area be-
tween the tractor and the implement can be entered only after the PTO shaft is completely
despinned!
15. Check for 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.
16. At transporting of the tractor with the trailed, semi-trailed and semi-mounted im-
plements for considerable distances, including from one field to another, disconnect the car-
dan shaft from the tractor and from the implement
17. Maintenance, cleaning and repair services of the implement with the cardan drive
coupled to the tractor shall be carried out only when the PTO shaft and the tractor engine
are disabled.
The PTO shaft shall be disabled in the following cases:
- after the tractor has been stopped, but only after the implement coupled has came
full duty cycle;
- on turns, when the implement is lifted to the transport position;
- when moving on the sharp climb and sharp descent.
Do not engage PTO shaft in the following cases:
- when the tractor engine is disengaged;
- the implement coupled to the tractor is in transport position;
- when the working attachments are sunken into the soil;
- if a process material overlays the implement working attachments or if the working
attachments are clogged or wedged;
- if the slope angle (refraction angle) in any plane of cardan shaft hinged joint is a
considerable.
