Safety Instructions for Disc-Roller
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:
1. The machine must be lowered to firm ground.
2. The hydraulics must be relieved.
3. The tractor must be stopped and the key removed from the ignition switch.
4. 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!
5. After operating the hydraulics, lower the machine to firm ground.
Relieve the hydraulics, stop the motor and remove the ignition key.
6. 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.
The life of hydraulic hoses is maximum 5 years.
New hydraulic hoses must meet the manufacturer's requirements.
INSTRUCTIONS ON TRANSPORT ON THE PUBLIC ROADS
Check before transport on public roads that the attachment of the machine at the tractor is in accordance with
the local rules and regulations in force (permitted total weight, permitted axle load, transport width, lights,
warning signs, etc.).
FRONT AXLE LOAD
After the attachment of the machine and at maximum load, the driving properties of the tractor must
be ensured. Check that the front axle is sufficiently loaded. As a minimum, the front axle load must
be 20% of the tractor weight. Permitted axle load and permitted total weight for the tractor must
always be observed.
NB! The driving, controlling and braking properties are affected by the attached machine
combination.

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 and tilt the depth stop backwards
towards the drawbar cylinder.
6. Unfold the edge equipment to working position.
7. Now lift and lower the discs to the required working depth.
Check that the towing hook height is between 400 and 500 mm.
Check that the male quick-couplings of the Disc-Roller fit the
female quick-couplings of the tractor.

Settings og adjustments
When starting-up the Disc-Roller 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
It is important that the top link (mounted model) or
the 2 adjusting bolts (A) on the drawbar (trailed model)
are adjusted correctly.
Drawbar height (recommended): approx. 500mm.
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.

Adjust the tine for the edge plate
(A), so that the material can pass
the rear disc. Huge amounts of
straw require greater space.
Edge equipment
Disc-Roller is standard equipped with edge equipment.
Adjust the edge plate (1), to keep the excavated soil in a
row.
Keep the edge plate (1) away from the ground to avoid
bending when turning.

Edge equipment from machine no. 341738
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.
New edge equipment for Disc-
Roller.
The disc can be adjusted so that the
excavated soil is collected. Keep the
disc away from the ground to avoid
bending when turning.

15
Scraper
The Disc-Roller has special designed scrapers amon
the packer rings.
To avoid unnecessary wear and to obtain the best
scraper effect it is important to check the centering of
the scrapers every day.
Scraper from 2009 - 2013:

Material damperguard
The Disc-Roller 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.
Tine eradicator set (can only be mounted on trailed models)
The trailed Disc-Roller can be equipped with tine eradicator set/ track
remover, which loosens the packed soil from the tractor wheels -
ensuring a uniform preparation of the soil.
The equipment is height adjustable, by unlocking 1 pin in each tine.
To dismount the tine eradicator, unlock pins and unbolt.

Maintenance and service
A. Grease hubs at the discs so that grease is appearing at the seals of the hubs.
Every 30 hours of operation grease again. If the machine is driving under difficult
conditions (much dust), grease more often.
Important:
B. After 10 hours of operation, retighten wheels, bearings and stop rings. Check hydraulic
hoses, fittings and cylinders for leaks and retighten.
C. Every 10 hours of operation, grease all pivoting points in side sections, drawbar and wheel
assembly.
D. After end season, grease and wash machine.
Important:
Oil, type Hydro Texaco HD 32 has been
filled in the hydraulic system.
Grease hubs at the discs before wash,
to avoid water penetration into the bearings.
Grease piston rods.
