Safety Instructions for Disc-Roller Contour
Do not start-up the machine if there are persons in exposed positions** within a hazardous area*.
When persons are in exposed positions (e.g. in connection with adjustment, maintenance,
attachment and uncoupling), the following conditions must be observed:
•The machine must be lowered to firm ground.
•The hydraulics must be relieved.
•The tractor must be stopped and the key removed from the ignition switch.
•The driver must ensure that no persons are staying in exposed positions during the
operation.
* Hazardous area: On and under the machine within a distance of 4 m from the machine.
** Person in exposed position: Any person who is staying wholly or partly within a
hazardous area.
Most accidents that happen in connection with the operation, transport and maintenance of
machines are caused by non-compliance with the most elementary safety conditions.
Therefore it is vital that anybody working at the machine carefully complies with the safety
instructions as well as other instructions applying to the machine.
The machine may only be operated, maintained and repaired by persons, who are familiar with this
work and who are further familiar with the possible elements of danger with this particular machine.
Instructions on Unloading and Placing
The machine is supplied completely assembled by our lorry. Our specially trained drivers will assist
in the unloading of the machine.
The machine must be driven from the lorry by means of a tractor on the ramps provided and
according to our driver's instructions.
Afterwards place the machine on level and firm ground.
ATTENTION !! Rotary parts and loose clothes are a dangerous combination.
IMPORTANT !! In connection with the risk of parts falling down, it may endanger the
lives of persons staying on the base frame of the machine, when it is
operated attached to a tractor.

Safety and Instructions on Hydraulics
1. The maximum working pressure is 225 bar.
2. It is advisable to label the attachment parts at hydraulic connections between the tractor and the tool
in order to eliminate incorrect operation!
3. When checking for hydraulic leaks, use suitable safety wear (eye protectors, gloves, etc.)
High-pressure hydraulic oil may penetrate the skin and cause dangerous injuries.
In case of injury, consult a doctor immediately. RISK OF INFECTION!
4. After operating the hydraulics, lower the machine to firm ground.
Relieve the hydraulics, stop the motor and remove the ignition key.
5. Check the hydraulic hoses on a regular basis, however, every six months as a minimum due to any
cracks, wear and tear, etc. Replace any defective hoses immediately.
6. The life of hydraulic hoses is maximum 5 years.
New hydraulic hoses must meet the manufacturer's requirements.
COMPLAINTS

Start-up of the machine
General Information
The machine is supplied as standard in transport position. At start-up, attach the machine to the
tractor.
Important:
The machine requires three double-acting outlets.
The hoses for the drawbar - / wheel cylinder are provided with red cable straps.
The hoses for the folding cylinder are provided with blue cable straps.
The hoses for the disc cylinder are provided with green cable straps.
Attachment, Mounted Model
1. Reverse the tractor to the machine and attach.
2. Connect all hydraulic hoses to the tractor outlets.
3. Lift the machine to maximum transport height.
Attachment, Trailed Model
1. Reverse the tractor to the machine.
2. Connect all hydraulic hoses to the tractor outlets.
3. Pressurise the drawbar - and the wheel cylinder (red) so that the machine
drawbar is lifted to the suitable height.
4. Then reverse the tractor and attach the machine.
5. Now lift the machine to maximum height.
Transport position to workposition
1. Important: When unfolding the side sections, the locking claw must first
be relieved by activating the folding function, until the side sections meet
the stop at the center frame. Next, when the unfolding function is activated,
the locking claw then first will open, after which the side sections are
unfolding.
2. When the side sections are completely unfolded, let go of the hydraulic handle
and the machine is ready for use.
Always set the tractor’s flow control on MAX, to make sure that the side
sections will follow each other.
3. Unfold the edge equipment to working position.
4. Now lift and lower the discs to the required working depth.
Check that the towing hook height is between 500 and 550 mm.
Check that the male quick-couplings of the Disc-Roller fit the
female quick-couplings of the tractor.

11 Back to the table of contents
Put the machine on level ground
and relieve the hydraulics, before
leaving the machine.
Transport
1. Lift the discs to the top before folding up the machine.
2. Then lift the machine to maximum transport height.
3. Fold up the side sections (blue) towards the stop on the centre frame, and the
locking claw will engage. It is important to check visually that the locking
claw is engaged. The hydraulic system must then briefly be put in the float
position after the locking pawls are engaged, until the locking claw has
relieved the hydraulics.
4. Now the machine is secured and ready for transport.
5. Lower the machine in order to minimise the transport height, to get a point of
gravety as low as possible. Slow and gentle cornering is recommended as
otherwise the machine is at risk to tip over.
Uncoupling, Mounted Model
1. Put down the machine on firm ground and relieve all hydraulic hoses.
2. Now the machine may be uncoupled.
Uncoupling, Trailed Model
1. Lift the machine up and tilt the depth stop on the drawbar forward towards
the tractor.
2. Now lower the machine onto firm ground.
3. Adjust the drawbar –and wheel cylinder (red) so that the drawing bolt is
loose.
4. Now the machine may be uncoupled.
5. Drive the tractor a little forward and then relieve all hydraulic hoses.

Settings and adjustment
When starting-up the Disc-Roller Contour in the field, it is very important that the machine is parallel
with the surface of the earth. The packing roller and the tractor keep the machine in an exact working
depth.
Drawbar
The horizontal position is adjusted on:
Mounted models:
By means of the top link
Trailed models:
By means of distance clips on the
drawbar cylinder
Height of the towing eye: approx. 500-550 mm
Disc
The Discs are adjusted up or down by a hydraulic
Master-Slave system.
It is important that the discs are regularly lifted to the top
to reset the Master-Slave system.
The depth position is readable on the scale (standard).
The sensor can be adjusted, where el. depth stop is mounted.
It is possible to over steer the electrical system by turning off the switch mounted in the cabin, now
the discs can pass the sensor, thereby a deeper working depth is achieved e.g. at headland and
tramlines.

HE-VA SAT-System:
Hydraulic adjustable weight transfer system, ensuring equal weight transfer in the total working
width, resulting in the fact that the wing sections are following the ground.
Manometer for pressure adjustment on 2-sections machines
In transport position, the hydr. pressure in the system is adjusted to approx. 50 bar. During
operation, the hydr. pressure will vary - depending on the soil surface.
In line –system (extra equipment)
for 1- og 2-sections models.
Hydraulic adjustment of the machines parallelism with the soil surface during work from tractor cab
–by means of Memory cylinder. Hereby it is secured that the machine in working in line after the
tractor, even in hilly ground.

Edge equipment
The edge equipment can be adjusted
three places:
1. Loosen two bolts –move the
arm out/in.
2. Use the spindle –it raises
and lowers the disc. Loosen
two bolts –raise/lower by
the spindle and retighten the
bolts.
3. Loosen one bolt –tilt the
disc more or less.
Edge equipment for Disc-Roller
Contour
The disc can be adjusted so that
excavated soil is collected.
Keep the disc away from the ground
to avoid bending when turning.

Scraper
The Disc-Roller Contour has special designed scrapers among the packer rings on the single V-
Profile and U-Profile as well as on the Wave Roller.
To avoid unnecessary wear and to obtain the best scraper effect it is important to check the
centering of the scrapers every day.
Material-damper-guard
The Disc-Roller Contour can be equipped with material damper guard, ensuring that excavated soil
from the discs is falling down before packing.
The material damper guard is height adjustable in 5 cm steps,
by unlocking 1 pin in each bracket.
To dismount the material damper guard, unlock pins and unbolt.

Maintenance and service
A. After 10 hours of operation, retighten wheels, bearings and stop rings. Check hydraulic
hoses, fittings and cylinders for leaks and retighten.
B. Every 10 hours of operation, grease all pivoting points in side sections, drawbar and wheel
assembly.
C. After end season, grease and wash machine, and grease the piston rods.
