Before starting repair work, depressurise system sections and pressure lines which
are to be opened!
Before starting maintenance work, remove all types of soiling from connections and

Noise
The A-rated equivalent continuous sound pressure level at the operator workstations
during normal operation of the gantry press is below 80 dB(A).
On account of the local conditions and different materials, there may be a higher
sound pressure level at the installation site of the gantry press. In this case the plant
operator is obliged to provide the operating personnel with the appropriate protective
equipment.
