The diameter of the lower link pins corresponds to CAT I.
Adapter sleeves will have to be used for CAT II.
In order to guarantee that the machine is attached to and detached
from the tractor safely, it is recommended that the procedure be car-
ried out in the following sequence:
•
Attaching the PTO shaft to the free shaft end on the machine.
(Where freewheel PTO shafts are used, the freewheel must be at-
tached to the machine side).
•
Hook the tractor lower link arms into the three point sockets.
•
Secure all pins using the appropriate securing plugs.
•
Attach the PTO shaft to the tractor's universal joint shaft.
(
Caution
: make sure that the PTO shaft is the correct length,
otherwise the tractor or the machine's angular gearbox may be
damaged when the machine is raised or lowered).
•
Attach the upper link.
•
Pretension the upper link to halfway along the slotted hole (see
Fig. 5-2/1)
•
Plug in the hydraulic lines
•
To uncouple the machine, follow the same procedure in reverse.
Instruct those present to leave the danger area behind or under-
neath the machine, since the machine may lurch backwards if
the halves of the upper link have been screwed apart by mistake
or if they break apart.
If fitted, adjust the lowering restrictor on the tractor.
