• We recommend the operator assigned to the machine not to wear clothing that could be caught by the machine. • During the use, the machine could emit dust. It is advised to verify the filters on the cabin ventilation system periodically or use suitable protection systems for the respiratory tracts such as anti-dust mask. -
Page 11: Mounting
• Hydraulic oil that flies out under high pressure can penetrate through the skin and cause serious injuries. Seek professional medical assistance immediately in the event of any injury. • Do not use the controls or flexible tubes as handles. These components are mo- bile and do not offer a stable support. -

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 versatile 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: 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 therefore crucial that you have thoroughly read the safety precautions that cover the machine.

Folding Fig. 10 1. The foldable and unfoldable cylin- ders (A) (marked: Red) are acti- vated so that it is as short as pos- sible. Fig. 11 2. The tilt cylinders (marked: White) are activated to full length and the drum is tilted away from the ground. -
Page 21: 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 ad- verse conditions. -

Page 27: 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 be- tween the tractor’s drawbar. Insert a cotter key or bolt; raise the support leg and set in working position (B). -
Page 28: 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 29: Adjustment
Some lubrication points most easily accessible with the machine unfolded. We recommend that the machine is placed (folded-in/folded-out) so that the lubri- cation nipples can be reached without having to go up onto the drum. Adjustment Adjustment of fittings After the first season, the fittings will have worked themselves loose on the shaft. By moving the stop rings on the shaft, the fittings can be clamped together to remove any dirt and wear can be minimized. -

Page 31: 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) before 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 32: 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 subjecting it to ... - Page 33 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 cylin- ders are moved in this way a few times.
- Page 34 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. If the cap is really stuck, it may help to warm up the front of the upper cap.

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 removed. 5. The bearings pos. 17+18 are re- moved. -
Page 41: 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 some- thing 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 42: 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 support the base and the bolts are loose. 3. Remove the bolts. 4. -
Page 43: Disposal
Disposal The drum must be unfolded. It is crucial to release the pressure from all the cylin- ders. With disassembly/dismounting, attention should be directed towards the load on the part in question. It is therefore important that this part be supported or lifted, to avoid risk of collapse or overturning. -
