On commissioning or operation of the overspeed protector, spraying hydraulic oil may
get into the eyes causing blindness. Wear protective glasses for all works performed on
the overspeed protector.
The overspeed protector is a hydraulic unit. In case of improper use, operating medium
being under pressure may leak out. Any improper use may lead to the leakage of
operating medium under pressure, posing a risk to the health and life of the operating
staff. Prior to performing any work on the overspeed protector, switch off the hydraulic
supply system.
During operation, the outer surfaces of the overspeed protector and the hydraulic
connecting lines may become hot due to the operating medium. Any contact may cause
injuries by burning. Prior to performing any work on the overspeed protector, let the
overspeed protector cool down.
On commissioning or operation of the overspeed protector, the end of the piston rod
may move uncontrolled in case of failure of the hydraulic or electric energy, due to
malfunctions in the master control or on the overspeed protector. This movement may
pose a risk to both individuals and objects. Prior to performing any work on the
overspeed protector, switch off the hydraulic and electric auxiliary energy.
Electric components
are integrated in the overspeed protector which may be destroyed,
e.g. during electric welding near the overspeed protector. Prior to performing electric
welding near the overspeed protector, remove all electric connecting lines.
Environmental protection
On assembly, disassembly or improper use of the overspeed protector, operating
medium may leak out. Operating medium getting into the sewage system or open soil
causes severe environmental damages. Collect any leaking operating medium and
dispose of it in accordance with the national statutory provisions.
Painting
In case of repaints or mendings of the paint on a device, please ensure that the
maximal permissible total film thickness will not be exceeded. For devices of Gas
Groups IIA and IIB, it is 2 mm and for devices of Gas Group IIC it is 0.2 mm.
