1. Foreword
Thank you for choosing a high-class Multiva Cerex seed  drill. We hope the product will meet your
requirements and provide years of reliable service. Please read this manual thoroughly before
operating the machine. It is important that you perform the inspection and maintenance
measures specied in this manual to ensure the awless operation of the machine and the
validity of the warranty. You must follow all the instructions, warnings and prohibitions related
to the use of the machine. They are provided to ensure operator safety and the long service life
of the machine.
Cerex is an effective and versatile seed  drill for seeding tilled soil. The machine is equipped with
a separate wheel for working depth adjustment, which provides precision seeding in ploughed,
reduced tillage and no tillage soils.
These instructions cover the Cerex 300 and Cerex 400 seed  drills and the Lykketronic, SeedPilot
and SeedPilot ISOBUS control systems.
1.1. Purpose of the machine
The operator of the seed  drill must acquaint themselves with the machine and read and
understand the contents of its operating manual before operating the machine. The seed drill
may only be operated when it is in a awless technical condition. The seed  drill must be used in
accordance with regulations, identifying hazards and following the safety and operating
instructions.
Original Multiva spare parts and accessories are designed for this particular seed  drill. The
manufacturer bears no responsibility for spare parts and accessories provided by other
suppliers.  Using them in certain circumstances may weaken the machine and compromise
personal safety.

machine allows road transport with the hoppers full. Any use exceeding this, such as using the
machine for transport, is not considered to be in accordance with the regulations. Use in
accordance with the regulations includes following the operating instructions and
manufacturer's instructions as well as regulations concerning service and maintenance.
Occupational safety regulations concerning agricultural machinery, other rules and regulations
on general safety technology and occupational health as well as traffic rules and regulations
must be followed.
