  • Page 30 5.1.3. Setting the edge clearances In order to limit the twine wrapping on the ends of the roll bale, the edge clearance retainers [1] are adjustable (the right side of the baler is shown in fig 30 and fig. 31, but the same applies to the left side):With very dry and brittle crops it is better if the retainers are located more towards the middle of the baler.
  • Page 31 6. Net Wrapping* 6.1. Inserting the net In order to handle the net roll safely, insert it together with the help of a second person! • Open all protective covers. • First place the net roll at an angle over both net roll recesses from the left side (Fig.

  • Page 33 6.2. Tensioning the net cutting knife The net cutting knife is automatically tensioned (reset) each time the tailgate is opened. If a new net wrapping is required without opening the tailgate while the bale chamber is full, due to a net changeover or fault, the tensioning process can be done manually.
  • Page 34 7. Cutting Device* RP 220 • RP 320 Depending on the model, the baler can be fitted with a 12-blade cutting device (MASTERCUT) or with a 23-blade cutting device (PROFICUT). It can be used for silage, hay and straw. The cutting device is hydraulically moved in and out.
  • Page 35 RP 220 FARMER - RP 320 FARMER with cutting unit and swivel floor Activating the cutting device: 1. Open the shut-off valve on the left side of the baler (fig. 43), i.e. move the lever into the vertical position. 2. Activate the "raise" function on the connected tractor valve until the cutting device moves into its working position.
  • Page 36 Hydraulic protection of the cutter blades Note: The cutting device is safeguarded from being overloaded by a single hydraulic pressure switch serving the cutter blades. This activates at a factory set pressure limit. This is also the pressure available for moving in the blades. Depending on the situation, the hydraulic pressure may not necessarily suffice if the blade grooves are blocked.
  • Page 37 RP 220 FARMER • RP 320 FARMER with cutting unit and without swivel floor The cutting device is directly actuated with the double-acting tractor control valve. (The actuating direction can be changed by swapping the connected hydraulic hoses.) In order to ensure free movement of the individual blades, it is recommended to move the cutting device in and out several times each day.
  • Page 38 7.2. Brittle crops It is recommended when baling brittle crops to hydraulically move the cutting device out of the cutting position before wrapping. The bales are then enclosed by long material and crumbling losses are avoided to a large extent. 7.3.
  • Page 39 7.4. Sharpening the cutter blades In order to ensure an optimum throughput of crops, it is recommended that the cutter blades be sharpened after 500 bales have been cut at the latest. Depending on the operating conditions, sharpening may also be required sooner. As described above, remove the blades and grind the cutting edge from the smooth side.
  • Page 40 8. Field Use The roll baler is safeguarded against foreseeable accidents. In spite of this, necessary precautions must still be taken when working. Each time before use, check that all safety devices on the roll baler are in proper working order. Never attempt to correct malfunctions while the machine is in operation.
  • Page 41 8.4. Pick-up unit RP 202 • RP 302 CLASSIC / SPECIAL RP 220 • RP 320 FARMER The pick-up unit is raised and lowered by operating the tractor control valve. RP 220 • RP 320 MASTER / PROFI / SPEEDMASTER / SPEEDPROFI An electro-hydraulic manifold block (Hydraulic switch*) makes it possible to operate a number of different hydraulic functions with a single control valve.
  • Page 42 Special Notes: 1742-42 RP 202 CLASSIC / RP 302 CLASSIC Pick-up unit width 1.50 m (fig. 56) As an optional feature, a pick-up unit short crop guard can be supplied (not shown).
  • Page 43 8.5. Feed guide plate The streamlined feed guide plate [1] is factory installed in the roll 1742-51 chamber. Should material become jammed due to unusual crop conditions, then the feed guide plate may be removed. To do this, take out screws (arrow in fig. 59) on the right side (in the driving direction) and remove the plate from the roll chamber.
  • Page 44 8.8. Setting the bale density RP 202 • RP 302 CLASSIC / SPECIAL RP 220 • RP 320 FARMER There is a lever on the right-hand side of the baler to set the density. 1. With the side panel open, loosen the wing nut. 2.
  • Page 45 8.9. Locking the tailgate Before picking up the crop and after each bale ejection, the tailgate must be locked properly. To do this, keep the tractor control valve for tailgate actuation in the "lower" position. This will automatically lock the tailgate. For balers with net wrapping, the tractor control valve must be kept in the "lower"...

  • Page 47 9.1.1. Triggering the wrapping (BALERCONTROL E) When the pre-selected bale density is reached, the tractor driver is notified by the red LED [2] and the buzzer [9]. Depending on the selected wrapping mode, the wrapping is triggered either automatically or manually from the appropriate button (net [6] or twine [7]).
  • Page 48 Automatic twine wrapping • Selection: Depress button [5] (fig. 62) several times until the right yellow LED lights up. • Once the pre-selected bale density is reached, the red LED initially begins to flash and then remains continually on. • The twine is automatically guided into the roll chamber.
  • Page 49 Combined net / twine wrapping In order to minimise crumbling losses and keep net consumption low, it is possible to use both types of wrapping simultaneously. • Activate the baler for automatic twine wrapping (see page 44). • Allow the twine wrapping to be triggered automatically. •...

  • Page 53 9.3. Ejecting the bale After completing the wrapping process, open the tailgate hydraulically so that the bale rolls out. Keep the tractor control valve on "raise" until the tailgate has completely opened. If no bale ejector* (see fig. 9, No. 8) is fitted, then reverse by approx.
  • Page 54 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.
  • Page 55 10.4. Reversing the pick-up unit RP 202 / RP 302 SPECIAL For blockages in the inlet section, the pick-up unit drive can be manually rotated backwards (see fig. 69): • Switch off the pto shaft • Switch off engine and remove the ignition key •...
  • Page 56 10.5. Hydraulic bottom flap* (HYDROFLEXCONTROL)* The hydraulically hinged conveyor channel floor has two hydraulic cylinders which help in extending the conveyor channel through to the roll chamber. Any congested material is thereby easily pulled through, grasped by the lower pressing roller and transported into the roll chamber.
  • Page 57 11. "BALERCONTROL"* Not only the control unit (only with BALERCNTROL III), but also the operating control panel, as well as the associated program, all have their own serial numbers. In order to process future enquiries, it is necessary to state the serial / version numbers.

  • Page 58: Your Safety

    11.1. Your Safety The "Balercontrol" control system was designed and manufactured with utmost attention to details and maximum precision. Each unit has been checked and tested for correct functioning before delivery. Despite all the precautions, a malfunction can still occur. Therefore, the "Balercontrol" control system and associated baler should be always operated in such a manner that prevents damage to person or property.
