Service and maintenance
Follow the safety instructions regarding
service and maintenance.
Your machine has been designed and assem-
bled for maximum performance, economy and
operator friendliness, under a wide range of
operating conditions.
Your machine has been tested in the factory and
by your authorised dealer prior to delivery to en-
sure that you receive it in optimum condition. In
order to maintain trouble-free operation, it is im-
portant that the service and maintenance work is
always carried out at the recommended intervals.
Cleaning
In order to maintain readiness for use and to
achieve optimum performance, always carry out
cleaning and servicing work at regular intervals.
Do not clean electrical components,
fan or hydraulic cylinders with a high-
pressure cleaner or direct jet of water.
The housing, screwed connections and
bearings are not watertight.
¾
Clean the outside of the machine with water.
Open the Venturi pipe under the metering
unit so that water which has flowed in can
drain away.
¾
Clean the metering roller in the metering unit
with a brush.
¾
Purge the coulters, seed pipes, seed hopper,
metering unit and fan with compressed air.
¾
If the machine has been operated with dry or
liquid fertiliser, clean and flush the compo
-
nents thoroughly. Fertilisers are extremely
aggressive and can cause corrosion.
Maintenance intervals
The maintenance intervals are determined by
many different factors.
For instance, not only do the different operating
conditions, climatic conditions, driving and op-
erating speeds, dust and type of soil, the seed,
fertiliser and dressing used, etc., have an effect
on the maintenance intervals, but the quality of
the lubricating agents and care products also
determines when the next service is due.
The maintenance intervals stated can therefore
only serve as a guide.
In case of deviations from the normal operat-
ing conditions, the intervals for the relevant
maintenance work must be adapted to the
conditions.
Preparation for storage
If the machine is to be out of operation for a
longer period:
¾
Park the machine under a roof, if possible.
¾
Empty the seed hopper and fertiliser tank
completely.
¾
Turn the coulter pressure control back in order
to relieve the rubbers so that they will not lose
their tensioning force.
¾
Open the emptying outlet.
¾
Disconnect the electrical control devices and
store them in a dry place.
¾
Protect the machine against rust. Use only
easily biodegradable oils, e.g., rape seed oil,
to spray the machine.
¾
Relieve the weight on the wheels.
¾
Protect the piston rods of the hydraulic cylin-
ders against corrosion.
Do not spray plastic and rubber parts
with oil or corrosion protection agent.
These parts could become brittle and
break.
