Care and maintenance
Inappropriate care and maintenance put the
operational safety of the machine at risk. This
can lead to accidents with severe or even fatal
physical injuries.
¾
Conform to prescribed schedules for repetitive
tests or inspections.
¾
Service the machine according to the
maintenance plan, see chapter Care and
maintenance .
¾
Only perform the work described in these
operating instructions.
¾
Before starting maintenance and service work
park the machine on level and firm ground and
secure it against rolling away.
¾
Depressurise the hydraulic system and lower
or support the implement.
¾
Prior to working on the electrical system,
disconnect it from the electric current supply.
¾
When performing welding work on the ma-
chine, disconnect the cables from computers
and other electronic components. The ground
connection must be as close as possible to
the welding point.
¾
Before cleaning the machine with high-pres-
sure cleaner cover all openings, which should
stay clear of water, steam or cleaning agents
for reasons of safety or operation. Do not aim
the water jet directly on electric or electronic
parts, on bearings or the fan.When using high
pressure cleaning equipment or steam jet, you
should always keep at least 50 cm distance
from the machine parts.
¾
Hopper, metering units, hoses and coulters
are contaminated with fertilisers and dressed
seed. Wear suitable protective outfit when
cleaning. Avoid contact and do not breath
the exhaust air.
¾
After cleaning, check all hydraulic lines for
leaks and loose connections.

edy any faults immediately!
¾
Screw connections loosened for the purpose
of care and maintenance work must be
retighten after work is completed.
¾
Do not clean new machines with a steam jet
of a high-pressure cleaner. The paint takes
approx. 3 months to cure and could thus be
damaged if this time has not yet expired.

which are not described in the operating
instructions, must only be carried out by
an authorized professional workshop or
by an operator who has been trained by
