Ignition hazards
The operating company – together with the responsible authorities – must fully evaluate the
operational risks, the local operating conditions and the monitoring methods that are required.
It is essential that the operating company complies with the necessary measures. Regarding
this topic, the machine manufacturer cannot provide any generally applicable
recommendations. Please observe the information in these operating instructions.

If a third-party certification is available for the machine, then carefully comply with the technical
data defined in it and any special conditions.
The certificate must be available before commissioning.
