     For hydraulic systems with built-in pilot-controlled non-return valves, it can be difficult to completely remove the pressure. You should hold a cloth around the fitting/part that is being removed to catch any oil that may leak.  After repairs on the hydraulic system have been completed, all air must be completely removed from the system.

    This is a standard roller, designed for rolling and levelling ploughed and sown areas. Rolling is intended on farming areas where better soil compaction is needed and to avoid the soil to dry out by extreme dry conditions. Rollers equipped with crackerboard is able to level ploughed areas with a per- fect result.

  • Page 17: Drawbar

    Drawbar Some countries require a special turn able drawbar like shown on the picture below. Setup on this drawbar type must be done exactly the same way than described in section “Setting up” on page 18. Page 17...

  • Page 18: Settings

    Settings The drum is factory set at delivery, but fine tuning will always be necessary before use. Many different adjustment options make your drums more versa- tile and enable optimal use of the machine. In order to achieve uniform pressure on the ground, the draw-bar must be adjusted correctly for the tractor concerned.
  • Page 19  To ensure correct settings, it is important that the machine is on a horizontal surface when the setting is set. Page 19...

  • Page 20: Driving And Operation

    Driving and operation Proper operation is important in order to get optimal performance from your drum. This applies to both work in the field and in terms of safety. It is there- fore crucial that you have thoroughly read the safety precautions that cover the machine.

    Folding Fig. 10 1. The foldable and unfoldable cylinders (A) (marked: Red) are activated so that it is as short as possible. Fig. 11 2. The tilt cylinders (marked: White) are activated to full length and the drum is tilted away from the ground.

  • Page 22: Driving Speed

    Driving speed It is recommended that the machine is driven at 6-10 km/h, and always in compliance with weather conditions. If speed is increased, wear will also increase, especially under dry conditions. There is also a risk of damaging the rings by driving at excessively high speeds under adverse conditions.

    Extra equipment It is possible to equip the MINIMAX 450-830 with different types of extra equipment.  Cracker boards with bowed worn parts  Gabions  Light Sets  Air brakes  Hydraulic brakes  Lift bar Cracker boards The clear advantages of the cracker boards are that the teeth can be moved individually so that they give after meeting resistance locally.

  • Page 27 Fig. 19 7 Mount the hoses according to the diagram shown in the “Hydraulic diagram” section. 8 The hoses are fastened to the hose holders (arrow) (not all hose holders can be seen in the figure). It is important to ventilate the system thoroughly in order to prevent personal injury.

  • Page 28: Connection With Towing Eye

    Connection with towing eye Fig. 20 The drum is connected to the tractor’s fixed drawbar, where the towing eye (A) should be between the tractor’s draw- bar. Insert a cotter key or bolt; raise the support leg and set in working position (B).

  • Page 29: Maintenance

    Maintenance Good maintenance ensures a long life for the drum and therefore optimal use of the machine. Which is why grease fittings have been installed in places where wear is greatest.  All screw connections must be tightened after the first day of work. Cotter pins and bolts should be checked to avoid breakdowns.

  • Page 30: Adjustment

    All lubrication points should be greased at least once a year. It is also rec-  ommended to spray protruding piston rods with oil when the drum has been cleaned, washed and parked for the longer term at the end of the sea- son.

  • Page 32: Worn Out Parts

    Worn out parts Fig. 23 The wear parts are factory-fitted in the upper holes on the tooth. The wear slides must be moved to the lower holes (A) be- fore wear starts to appear on the teeth. After the wear parts are worn out. Positioned in the lower holes, replace the slides so that no wear occurs on the cracker board.

  • Page 33: Replacements And Repairs

    Replacements and repairs  Safety is crucial in regard to all repair work on the drum. The following items must therefore be observed at all times, as well as all items under safety at the beginning of the instruction manual. When replacing the cylinders, always fill the cylinder with oil before subject- ...
  • Page 34 After mounting, the cylinders are activated for unfolding and folding until a small amount of movement can be felt in the cylinders. The cylinders are then activated in the opposite direction until the cylinders are back in the starting position. The cylinders are moved in this way a few times. The drum is then tilted up onto the wheels and the side sections move out completely into the outer positions to air out the system.
  • Page 35 Replacement of the gaskets DISMANTLING: 1. Empty the cylinder of oil, (if necessary, use compressed air to move the piston back and forth to push the oil out). 2. Drive the piston to the centre position. The cap (pos. 3) is unscrewed 30 mm.

  • Page 36: Changing The Tilt Cylinder

    Changing the tilt cylinder Fig. 26 The drum is unfolded and lowered onto the base (working position). The pressure is re- moved from the tilting cylinder (A). 1. The hoses are disconnected from the cylinder. 2. The cylinder is supported. 3.

  • Page 40: Removing/Mounting Wheels On The Road

    Removing/mounting wheels on the road To remove a wheel on the road, hoist the drum with a strap and crane (A), or jack (B) as shown in the pictures below. The wheel will thus be free of the ground. The wheel nuts are removed and the wheel can be replaced. After installing the new wheel, screw the nuts on and tighten with a “firm hand”.

  • Page 41: Replacing The Bearings

    Replacing the bearings Fig. 31 1. The hub cap pos. 21 is removed. 2. The cotter pos. 20 is removed. 3. The castellated nut pos. 19 is re- moved. 4. The axle pos. 2 can now be re- moved. 5. The bearings pos. 17+18 are re- moved.

  • Page 42: Dismantling The Drum Body

    Dismantling the drum body Perform repairs on a flat surface with the drum connected to a tractor and unfolded with the rings resting on the ground. It would be very helpful to have a crane or something similar available for both the dismantling and assembly. Replacement of the drum body on the side sections If no crane is available, both axles on the side sections must be removed to prevent the drum from overturning.

  • Page 43: Replacement Of The Centre Drum Body

    Replacement of the centre drum body Fig. 33 1. Loosen the bolts (A). 2. The tilt cylinder is activated, the drum is tilted towards the wheels, the drum rings sup- port the base and the bolts are loose. 3. Remove the bolts. 4.

  • Page 44: Disposal

    Disposal The drum must be unfolded. It is crucial to release the pressure from all the cylinders. With disassembly/dismounting, attention should be directed towards the load on the part in question. It is therefore important that this part be sup- ported or lifted, to avoid risk of collapse or overturning.
