    Rollomaximum XL Safety This symbol appears in the instruction manual each time there is a safety warning concerning your safety, the safety of others or the safe operation of the machine. All safety instructions must be observed and made available to all users of the machine.

  • Page 7: Hydraulics

    Rollomaximum XL Hydraulics  Fold out machine and set down on an underlay for any repair work on the hydraulic system. Relieve hydraulic pressure, switch engine off and re- move ignition key.  Clean hydraulic connections thoroughly before reconnecting. When con- necting hydraulic hoses to tractor hydraulics, ensure they are not under pressure.

  • Page 8: Road Transport

    Rollomaximum XL Road transport  All statutorily required safety and warning features must be fitted and tested before transporting the machine on public roads. The driver is re- sponsible for correct lighting and warning signs in accordance with traffic regulations.

    Rollomaximum XL How to use this manual The sequence of topics in this manual may at first glance not always appear to be logical. Please refer to the table of contents for page numbers for individu- al items. The manual is divided into main sections: ...

  • Page 10: Limitations To Use

    Rollomaximum XL Limitations to use The following describes what the machine can and cannot be used for:  The machine may only be used for levelling, compacting and harrowing cultivated land. Fields on which the machine is used must be well tilled, i.e. without major unevenness or potholes.

  • Page 11: Description Of The Machine

    Rollomaximum XL Description of the machine Construction The Rollomaximum XL is a robust, multifunctional agricultural implement with the fol- lowing features:  The machine consists of 5 different working implements. At the front there is a parallel-mounted hydraulically adjustable crackerboard, followed by a Ø53/Ø48 cm cross-kill roller.

  • Page 12: Connecting And Disconnecting

     Rollomaximum XL 930 / 1240 may only be hitched to a tractor via a pick-up hitch as shown in the photo on this page. Never use a ball hitch or the tractor lift arms.

  • Page 14: Setting Up

    Rollomaximum XL Setting up Rollomaximum is supplied with factory settings, but fine adjustment will al- ways be required before use. Numerous adjustment options make the machine more flexible and optimise its use. To ensure that the ground is uniformly worked, the drawbar must be correctly aligned to the tractor used.

  • Page 15: Extension

    Rollomaximum XL Ensure there are no personnel within the machine's working radius when extending or retracting. Extension Lift side sections off the transport cradle (A) with the tilt cylinder (marked: white valve block no. 4). Extend/retract cylinder (marked: Red) is activated and the side sections are completely folded out.

  • Page 16: Retraction

    Rollomaximum XL Retraction The wheel frame (marked: yellow) is activated and the machine is lifted off the ground. The tilt cylinder (marked: white valve block no. 4) is retracted and the machine is tilted forward to the side frames and the centre frame is in the upright position.
  • Page 17 Rollomaximum XL To reduce the height of the ma- chine's centre of gravity and lower the transport height to a maximum of 4 metres, the ma- chine can be lowered via the 400 cm wheel frame (A) (marked: yel- low). The machine is lowered until there is approx.

  • Page 18: Adjustment Of Hydraulic Weight Transfer System

    The accumulator precharge pressure (air pressure) is pre-set ex works, but must be adjusted according to the actual type and character of the soil. This must be done in consultation with a licensed Dal-Bo dealer. Check all the accumulators on the machine at least once a year for leaks and to ensure that the precharge pressure is set correctly.

  • Page 19: Excess Pressure

    Rollomaximum XL Excess pressure 1 Pressure on the side sections will be too great, leaving clear tracks in the soil after the side sections have passed. 2 The centre section will not compact the soil enough, as the soil after the centre section has passed is higher and not as compacted as that worked by the side sections.

  • Page 20: Operating Speed

    Rollomaximum XL  If the pressure on the centre axle are not identical with that on the side arm axles, the pressure in the hydraulic system may be dissipat- ed and the system should be refilled with oil. If, however, the earth piles up in front of the centre axle or the it only clears rocks with difficulty, the pressure is too high and should be lowered.

  • Page 21: Adjusting Harrowing Depth

    Rollomaximum XL  Raise crackerboard to highest position for adjustment of tine angle. The tine angle selected depends on the nature of the job. If they are set ag- gressively while the depth is set for the upper soil layer, maximum vibration will be created for fine-crushing of lumps and an optimum smoothing effect.

  • Page 22: Adjusting The Rear Levelling Board

    Rollomaximum XL The harrowing depth is adjusted incrementally by the "hydro clip" spacer rings (B), which are mechan- ically mounted by hand on the har- row section's raise/lower cylinder on each side. In total, there are two cylinders on the machine, and the same and equal number of spacer rings must be fitted to each.

  • Page 27: Replacement And Repairs

    Rollomaximum XL Replacement and repairs  Safety is vital in the performance of all repair work on the machine. Always observe the following points, plus those under Safety First in the instruction manual. When replacing cylinders, always fill the new cylinder with oil before pres- surising system.
  • Page 28 Rollomaximum XL Activate extend cylinder after fitting until cylinder shows movement. Reverse cylinder until it returns to start position. Move cylinder backwards and for- wards several times. If air is not correctly bled off from the cylinder as described above, there is a risk that part of the machine can suddenly move much quicker than nor- mal, before the tractor driver can prevent it.

  • Page 29: Replacing The Tilt Cylinder (White Valve Block No. 4)

    Rollomaximum XL 1. Fit new gaskets in upper part and collar shoe. The scraper ring is mounted using a piece of pipe, passed around outside of lip, (or a special drift). Fit collar (9) onto collar shoe using tubular bar or screwdriver.
  • Page 30 Rollomaximum XL Ensure no personnel are within the extension radius of the side sections. Replacing gasket in tilt cylinder 1. Drain oil from cylinder by moving ram carefully backwards and forwards. 2. Extend cylinder halfway. Unscrew and remove upper part (3) from cylin- der tube (1).

    Rollomaximum XL 3. Remove split pins from pins, remove pins 4. Remove cylinder 5. Fit new or repaired cylinder After fitting, the harrow hoist is actuated until the cylinder shows a slight travel. Reverse cylinder until it returns to start position. Move cylinder back- wards and forwards several times.

  • Page 33: Replacing The Track Loosener Cylinder (White Valve Block No. 2)

    Rollomaximum XL If cylinder is not bled correctly as described above, there is a risk that part of the machine can suddenly move much quicker than normal, and before the tractor driver can prevent it. This is because air (unlike oil) is com- pressible.

  • Page 34: Replacing The Crackerboard Cylinder (Green)

    Rollomaximum XL See the section "Replacing gaskets on tilt cylinder" Replacing the crackerboard cylinder (green) The machine is extended to the working position, the wheels are raised so that the two cross-kill roll- ers are resting on the ground. The crackerboard tines (A) are then low- ered so that they rest on the ground.
  • Page 35 Rollomaximum XL Replacing the gasket set in the crackerboard cylinder Cylinder 25/60/25-205 1 Drain oil from cylinder by moving ram carefully backwards and forwards. 2 Extend cylinder halfway. Unscrew and remove upper part (3) from cyl- inder tube (1). Use special tool to remove upper part. If upper part is stuck, heat front of upper part.
