•
there is a hazard of head injury when you perform maintenance or replacement of
parts in or under the implement without adequate protection – wear a hardhat,
•
during a break in the work, always lower the implement to the ground and stop the
tractor engine,
•
the harrow with the working width exceeding 3.00 m is equipped with a mechanical
lock which blocks the side extensions from uncontrolled opening during standstill
and road travel,
•
driving and parking the implement on an unstable slope may cause soil slipping,
•
store the implement in a manner preventing injury to people and animals.
3.1
Hitching and unhitching from a tractor
•
Hitch the implement with the tractor according to the recommendations, use pins
and protect the suspension pins with cotter pins.
•
When hitching the disc harrow, do not stay between the tractor and the attached
implement.
•
The tractor used together with the disc harrow must be fully functional and in good
working order. It is forbidden to couple the machine to any tractor with a
malfunctioning pneumatic system (if the machine has a braked axle) and hydraulic
system.
•
Remember to observe the following: balance of the tractor and the suspended
implement, tractor steerability and braking performance – the front axle load must
not drop below 20% of the total tractor load – a kit of front weights;
•
When in resting position and disconnected from the tractor, the machine must be
stable all the time.
•
Place the support leg on a stable ground. Do not use pads under the leg as this may
cause instability.
3.2
Tyres
•
Tyre pressure cannot exceed the value recommended by the manufacturer.
Transporting the implement when the pressure is too low is prohibited. This may
cause damage to the implement or an accident when travelling too fast and on very
uneven surfaces.
•
Considerably damaged tyres (particularly the tyre profile) must be replaced
immediately.
•
Protect the implement from rolling away when replacing the tyres.
•
The repair works on wheels or tyres must be performed by persons trained and
authorised for this purpose. Such works must be performed with properly selected
tools.
•
Following every assembly of wheels, check the tightening of nuts after travelling
the distance of 50 km.
3.3
Hydraulic and pneumatic systems
The hydraulic and pneumatic systems are pressurised.
Take all precautionary measures, in particular:
•
do not connect and disconnect hydraulic hoses when the tractor hydraulic system is
pressurised (hydraulics set to neutral),
