Introduction
The operator must follow the safety instructions in this
manual and in the machine's operator's manual as well
as respect the warnings posted on the machine. The
operator is also obliged to respect current legislation
concerning accident prevention, work safety and public
traffic circulation.
Read and follow the safety instructions
Before using the control box, carefully read all safety
instructions in this manual.
Before starting work, the operator must be familiar with
all machine controls, handling devices and their
functions. It is too late to learn once work has been
started!
Never let anyone operate the machine who is not trained
to do so.
Should you have any difficulties in understanding certain
parts in this manual, please contact your KUHN dealer.
