through proper care and operation can you expect to receive the performance and long service built into it.
This manual contains all the necessary information for you to receive full efficiency from your machine. The
performance you get from this machine is largely dependent on how well you read and understand this
manual and apply this knowledge. Please DO NOT ASSUME YOU KNOW HOW TO OPERATE AND

About improvements
We are continually striving to improve our products. We therefore reserve the right to make improvements
or changes when it becomes practical to do so, without incurring any obligations to make changes or
additions to the equipment sold previously.
Wear parts
Wearing parts fitted on our machines have been tested in very different situations to optimize their service
life. Nevertheless, the service life depends highly on the conditions of use (products to handle, soil, weather
conditions, etc...).
Document illustrations
The illustrations in this manual may be based on one type of machine only. However, all instructions apply
to all machines covered in this manual.
