10. Overload protection /
Reversing mechanism
10.1. Universal drive shaft with shearing bolt
clutch*
A shearing bolt clutch is installed in the universal drive shaft on
the baler side. In the event of overloading, the bolt [1] will shear
and must be subsequently replaced by a new one. Only put the
machine into operation again when the cause for the overload
has been resolved.
Use original replacement parts only:
1741-81
Shearing bolt with nut ............................................ 0930.84.53.00
10.2. Universal drive shaft with cam-type cut-out
clutch*
The cam-type cut out clutch limits the drive torque in the event
of overload. Switch off the pto shaft and remedy the cause of
the overload. After switching on the pto shaft, the torque
increases once again, so that the baler can be put into
operation.
Avoid long and frequent overloading. Ensure that only the
1741-82 appropriate universal drive shaft is used.

10.3. Reversing the main drive

RP 220 / RP 320 without HYDROFLEXCONTROL*
Should the inlet section become blocked for balers without
hydraulic bottom flaps (HYDROFLEXCONTROL), the main
drive can be manually rotated backwards (fig. 77):
•
Switch off the pto shaft
•
Switch off engine and remove the ignition key
• Apply the crank lever delivered with the baler (46 mm jaw
width) and rotate the drive backwards far enough so that the
blockage in the inlet section can be removed;
Before restarting the baler, remove the crank lever and
close up all protective guards!
