Safety
You will find this symbol in the instruction manual each time advice is given regard-
ing your own safety, the safety of others or the safe operation of the machine. All
safety instructions must be observed and made available to all users of the ma-
chine.
General
•Before starting work, the user must be familiar with all parts of the machine.
•Safety markings have been placed on the machine that contain important in-
structions about your own and others' safety, as well as on the correct use of
the machine.
•There must be no passengers on the machine, either during work or transporta-
tion.
•When operating the drum, it must be ensured that there is no one located within
reach of the machine. The machine may only be operated from inside the trac-
tor.
•The hand levers are secured against unintentional operation.
•Before leaving the tractor or if adjustments, maintenance or repairs must be
made to the drum, the machine must be secured against accidental starting by
lowering the machinery at the base or maintaining it in transport position, the
tractor is braked, the engine stopped and the ignition key removed.
•Remember to secure the support and any lifting arms with linchpins.
•Never leave the driver's seat while the machine is driving.
•The driving speed must always be adjusted to the conditions.
•Only use the machine if all safety devices have been mounted. Defective safety
devices must be replaced immediately.

Hydraulics
•Before making any repairs to the hydraulics system the machinery must be
lowered at the base, the pressure released from the system, the engine stopped
and the ignition key removed.
•Hydraulic connections must be cleaned thoroughly before connecting. When
connecting the hydraulic hoses to the tractor's hydraulics, it is vital that you
ensure the pressure has first been released from the hydraulic system.
•For hydraulic systems with a built-in, pilot-operated check valve, it can be diffi-
cult to release the pressure completely. In this case hold a rag around the rele-
vant fittings/part, which is being uninstalled in order to stem any oil leakage.
•After repairs on the hydraulic system have been completed, all air must be thor-
oughly removed from the system.
•Check the hydraulic hoses regularly for defects such as tears, cracks, wear or
damage. Defective hoses must be replaced immediately.
•Avoid spilling oil on the ground. If this should happen anyway, it should be col-
lected and sent for destruction.
•Hands must be cleaned thoroughly after contact with oil and grease on the skin.
Change out of oil-soaked clothing immediately, as this can be harmful to the
skin.
•Hydraulic oil that flies out under high pressure can penetrate the skin and cause
serious injuries. Seek professional medical assistance immediately in the event
of any injury.
Installation
•There is a risk of being crushed when mounting. People must not be positioned
between the machinery and the tractor or between the parts that are being
connected.
Maintenance and repair
•When carrying out all repair and maintenance work the machine must be proper-
ly supported or unfolded, the tractor and machine must be properly braked, the
engine turned off and the keys removed.
•Tighten all screw fittings after a few hours of use. All screw fittings must be
checked at regular intervals and tightened when necessary. Check cotter pins
and bolts to avoid breakdowns.
•Oil, grease and filters shall be disposed of in accordance with the applicable en-
vironmental legislation.

COMBIFLEX

Driving on roads
•When driving on public roads, all safety arrangements and warnings required by
law must be mounted and tested. The driver is responsible for correct use of
lights and marking in accordance with the highway code.
•In consideration for the dimensions of the machinery the driver must refer to
traffic authorities to ensure that it may be transported on public roads.
•When transporting the machine, the total weight of the tractor must be taken in-
to consideration, the pressure on the axles must not be exceeded, and the load
on the tractor's front axle must not be less than 20 percent of the vehicle's total
weight. In this case the ballast weight of the tractor must be used.
Correct use
•The correct use of the machine also includes complying with the manufacturer's
operating, maintenance and repair instructions, as well as using only original
spare parts.
•The drum may only be used, maintained and repaired by people who are familiar
with the machine and who have knowledge of the dangers that can arise.
•The manufacturer is not liable for damage as a result of changes to the machine
that are carried out without the manufacturer's prior consent. Furthermore, the
manufacturer is not liable for any damage that results from incorrect use. Re-
sponsibility for this rests solely with the user.
•Extra weight must not be mounted on the drum.

Limitations in use
The following describes what the machine may/may not be used for:
•The machine may only be used for rolling and levelling of ploughed or germinated agricultural are-
as which are in rotation. The drum can also be used for rolling grass in fields. The areas that are be-
ing cultivated must be in a state of normal agricultural maintenance, that are without significant
irregularities or holes.
•The machine may only be used tightened to an agricultural tractor where it must be attached to its
drawbar. It can be transported on public roads via the tractor's three-point hitch.
•The machine can work at a maximum speed of 10 km/h. The speed shall, however, always be ad-
justed to the nature of the area.
Any other use of the machine, which does not fulfil the above-mentioned conditions, will be con-
sidered as unauthorised use and will result in the factory warranty being void.

Settings
The drum has been factory set by the manufacturer, but a fine tuning will always be
necessary before use. Many different adjustment possibilities make your drum
more versatile and allow the opportunity to obtain optimal use from the machine.
In order to achieve uniform pressure across the field the tow must be set correctly for the tractor in ques-
tion. The hitch height of the tractor must be between 35-60 cm.

Driving and operating
Correct operation is important in order to get the optimal benefit from your drum.
This applies not only to working in the field but also in terms of safety. Thus, it is im-
portant to study the safety information relevant to the machine
There must never be people present within the machinery's range of movement.
Driving speed
Driving at 6-10 km/h is recommended, but driving must always be carried out ac-
cording to the conditions.
The power requirement is very dependent on the type of soil and terrain as well as
the speed.

Maintenance
Good maintenance ensures a long lifetime for the drum and thus optimal use of the
machine. Lubrication points have therefore been mounted in the places where wear
and tear are greatest.

All screw connections must be tightened after the first day of work. Cotters and
bolts are checked in order to avoid breakdown.

Replacements and repairs

Safety is important with regards to all repair work on the drum. The following items
must therefore be observed at all times, as well as the items under safety at the
beginning of the instruction manual.
When replacing cylinders, the cylinder must always be filled with oil before it is sub-
jected to any load. It is therefore recommended that the cylinder is mounted on the
fixed part of the frame first, after which the cylinder is filled with oil and then
mounted onto the opposing section.
All maintenance and repair work on the drum may only be carried out after the ma-
chine has been secured against accidental starting by lowering the machinery at
the base or maintaining it in transport position, the tractor is braked, the engine
stopped and the ignition key removed.
For all repair work on the hydraulics, always pay close attention to safety. Before
starting work, the pressure must be released from the hydraulic system and it is a
requirement that the section is supported from below.
After any repair work on the hydraulic system, all air must be removed from the sys-
tem before use in order to protect against breakdown and personal
injury.

•Make sure the hydraulic hoses have not been crushed.
Disconnecting
The wheel frame must be unfolded before disconnecting.
Remove the stud and uninstall the hydraulic hoses.
Remember to release the pressure from the connecting hoses to the hydraulic sys-
tem before disconnecting the hoses.
Releasing air from the system
Longer periods of inactivity can result in small amounts of air getting into the sys-
tem. This can be seen while working with the boards not completely aligned. In this
case, the air must be released from the system. This is done by moving the board to
its maximum depth with use of hydraulics (the cylinders must be as short as possi-
ble). In this position, keep the pressure on the system for some time (try to make
the cylinders even shorter), even though the cylinders are as low as they can go.
The cylinders are designed so that when in their shortest position possible, oil can
pass through the piston via a channel. Thus forcing any air out of the system.
