Safety
The safety alert symbol is used throughout this manual to identify important
safety warning messages concerning your safety, the safety of other users or
the functional safety of the implement. Observe all safety instructions and
make them readily accessible to all users of the equipment.
General
•The operator must be thoroughly familiar with all safety precautions and
operations of this equipment prior to using.
•The safety signs on the MaxiDisc contain important instructions concern-
ing your safety, the safety of those around you, and the correct operation
of the machinery.
•Never allow anyone to ride on the implement during operation or trans-
port.
•Never allow bystanders within the operating radius of the MaxiDisc when
the implement is in operation. Operate the MaxiDisc only while seated in
the driver’s seat of the tractor.
•Ensure that wing section locks are engaged when the MaxiDisc is in a
folded position. Secure control levers against unintentional operation.
•Before performing any adjustments, maintenance or repairs on the ma-
chinery, always unfold the MaxiDisc and lower the implement to the
ground or secure in transport position, set the tractor brakes, turn off the
engine and remove the ignition key.
•Remember to secure the drawbar stand and the lift arms (if applicable)

Hydraulic System
•Never allow bystanders within the operating radius of the MaxiDisc when
the hydraulic system is activated to avoid the danger of an individual be-
ing crushed or pinched between the equipment.
•Before performing maintenance or repairs on the hydraulic system, lower
the implement to the ground, relieve pressure in the system, turn off the
engine and remove the ignition key.
•Clean the hydraulic fittings thoroughly before connection. Ensure that the
pressure is relieved in the hydraulic system before connecting the hydrau-
lic hoses to the tractor’s hydraulic services.
•After making repairs to the hydraulic system, thoroughly bleed air out of
the system.
•Regularly check hydraulic hoses for defects such as cracks, bends, chafing
or leaks.
•Avoid spilling oil on the ground. In case of spills, collect the oil and dis-
pose of it properly.
•In case skin should come in contact with hydraulic oil or grease or in case
clothing should become stained with oil, remove the stained clothes im-
mediately and wash the affected skin areas thoroughly. Oil and grease are
harmful to the skin.
•Escaping hydraulic oil under high pressure can penetrate the skin and
cause severe injury. If an accident occurs, see a doctor immediately.
Hitching
•An individual is in danger of being crushed during the hitching process.
Never place yourself or anyone else between the tractor and the Maxi-
Disc, or between parts that must be attached or connected.
Maintenance and Repairs
•Before servicing or making adjustments to the machine, securely block or
unfold the machine, engage the tractor and machine brakes, stop the en-
gine and remove the keys.
•Tighten all nuts, bolts hydraulic fittings or any other fastened assemblies
after a few hours’ use. Check often to make sure that they remain thor-
oughly tightened. Inspect all pins, screws and bolts for wear or damage
and make sure that all are securely in place to avoid any possible damage
or breakdown of the machine.

•Dispose of oil, grease and filters according to applicable environmental
regulations.
Transport
•All safety and warning signs and devices required by law must be dis-
played, mounted and tested for public road use. The driver is responsible
for the correct use of lights and markings in compliance with the present
Traffic Act and Highway Code of the local traffic legislation.
•It is the responsibility of the driver to consult with local traffic authorities
in order to ensure that the size, weight and load of the machinery may be
transported on public roads.
•When towing the implement, the total weight of the tractor and the maxi-
mum allowed axle load must not be exceeded. The weight on the front
axle must not be less than 20 percent of the total mass of the tractor. If it is
less than 20 percent, extra weight must be added to the front of the tractor.
Correct Use
•Correct use of the MaxiDisc includes adherence to the instructions of the
manufacturer concerning operation, maintenance and repair, as well as the
use of genuine factory replacement parts.
•Do not allow anyone to operate, maintain or repair the MaxiDisc unless
they are familiar with the implement and they are thoroughly aware of the
possible hazards.
•The manufacturer does not accept any liability for injury or warranty if the
equipment has been altered in any way without prior authorization from
the manufacturer or if the injury is a result of incorrect use of the imple-
ment. The user accepts complete responsibility in these cases.
•Never load extra weight onto the MaxiDisc.
