accidents during machine operation, maintenance and repair. An accident can
often be avoided by recognising potential hazardous situations before they
occur. The operator has to pay attention to potential hazards and have training,
competences and correct tools to carry out these tasks properly.
The improper use of the machine either during operation or maintenance could
be dangerous and cause serious accidents.
Do not operate the machine or carry out maintenance until these instructions

machine. If the operator does not pay attention to these warnings he could
have an accident with serious consequences for himself and others.

potentially dangerous.
The warnings in this manual and on the machine are not exhaustive.
