  • 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 following 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 / 1230 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: Adjusting Drawbar Height

    ROLLOMAXIMUM XL ROLLOMAXIMUM is supplied with factory settings, but fine adjustment will always 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 16: Retraction

    ROLLOMAXIMUM XL Retraction The wheel frame (marked: yel- low) is activated and the ma- chine is lifted off the ground. The tilt cylinder (marked: white valve block no. 4) is retracted and the machine is tilted for- ward to the side frames and the centre frame is in the up- right 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 machine can be lowered via the wheel frame (A) 400 cm (marked: yellow). The machine is lowered until there is approx.

  • Page 18: Adjustment Of Hydraulic Weight Transfer System

    ROLLOMAXIMUM XL Adjustment of hydraulic weight transfer system The hydraulic weight transfer system distributes the weight evenly between all the machine's sections. Once the roller is fully extended and the transport wheels are off the ground, the extend/retract cylinders are depressurised (marked: red), the cylinder control lever is then moved in the opposite direction.

  • Page 19: Adjustment Of The Hydraulic Suspension On The Middle Cross-Kill Shaft

    ROLLOMAXIMUM XL  To prolong the ROLLOMAXIMUM's service life and the optimise the tilled field finish, it is very important that the extend/retract outlet (marked: Red) is set to the float position for field work.  If the outlet (marked: red) is not set to float position, this constitutes in- correct use and in the worst case may cause the frame to break.

  • Page 20: Operating Speed

    ROLLOMAXIMUM XL Operating speed An operating speed of 6-10 km/h is recommended, but always operate according to conditions. Power requirement will depend on soil type, terrain and speed. This is a crucial fac- tor as it determines the working depth with crackerboards and the harrow section.

  • Page 21: Adjusting Harrowing Depth

    ROLLOMAXIMUM XL A deeper setting will increase the level- ling effect to that of a levelling board, as a small bank of soil builds up in front of the tines. It is not designed to act as a dozer blade, but to break the soil down. As each tine can move individually and thus yield to localised pressure, the crackerboard is easy to use and requires little adjustment compared to a levelling board.

  • Page 22: Adjusting The Rear Levelling Board

    ROLLOMAXIMUM XL The hydro-clip spacer rings (C) are stowed on the scale (D), when not in use. If no spacer rings are used on the cylinder, the harrow can go to the max- imum depth. Two types of hydro-clip are supplied with the machine with a total of 4x 31.8 mm and 6x 21.4 mm...

  • Page 26: 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 pressurising system.
  • Page 27 ROLLOMAXIMUM XL Activate extend cylinder after fitting until cylinder shows movement. Reverse cyl- inder until it returns to start position. Move cylinder backwards and forwards sev- eral 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 normal, before the tractor driver can prevent it.

  • Page 28: 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 29 ROLLOMAXIMUM XL 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 cylinder tube (1). Use special tool to remove upper part. If upper part is stuck, heat front of upper part.

    ROLLOMAXIMUM XL therefore swing out very quickly if air bleeding is not performed correctly. This rep- resents a major risk of injury to personnel and of damage to the machine. Ensure no personnel are within the extension radius of the side sections.
  • Page 33 ROLLOMAXIMUM XL The machine is extended to the work- ing position, the wheels are raised so that the two cross-kill rollers are rest- ing on the ground. The crackerboard tines (A) are then lowered so that they rest on the ground. The cylinder is then depressurised (B).
