4. Maintenance, care and transport:
The PTO shaft must always be disengaged and the ignition key removed before starting
any maintenance and repair work on the power harrow!
Maintenance or repair work must never be performed underneath the rotary power harrow
without appropriate supports. Precautions must always be taken to prevent the machine from
dropping inadvertently, for instance by using hoisting gear.
The rotary power harrow should always be placed on firm, level ground.
The power harrow type LXG is designed and built to require as little maintenance and care as
possible.
However, the following points should be observed nevertheless:
- All nuts, bolts and screws must be examined after the first five hours of operation and
then always before using the machine in order to ensure that they are secure. They
must be retightened if necessary.
- The PTO shaft must be lubricated with sufficient sulphur-free grease every eight hours
of operation so that it can always be extended and retracted without difficulty. The
bearing points on the cutter unit, the spindle for setting the working depth and the
roller mount must be lubricated every 30 hours of operation via the corresponding
grease nipples.
- The oil must be checked every 20 hours of operation.
- Gear oil must be changed after approx. 200 hours of operation. A container must be
placed under the machine to collect the escaping oil and prevent contamination of the
ground. Waste oil must be disposed of in accordance with the regulations.
- The rotary power harrow should be stored in a dry place, on firm, level ground. It
should be secured with chocks or similar objects to prevent inadvertent tilting.
- The machine must be thoroughly cleaned before prolonged storage. Those parts which
are in contact with the ground during operation should be sprayed with corrosion
inhibitor.
- Particular attention must be paid to the condition of the tines in order to ensure
maximum occupational safety and high-quality results. Before starting work, the tine
must therefore be examined to ensure they are correctly secured and wear down
evenly. Bent tines must be replaced immediately.
- Vibrations in the rotary power harrow are usually due to imbalances in the tine unit
and may damage the machine. Switch off the rotary power harrow and the tractor if
the vibrations increase significantly during operation or if the machine’s running noise
changes suddenly. The cause must be located and remedied before resuming work.
