4.8 DANGERS PRESENT IN USE
The verification of conformity with the essential safety requirements and regulations of the Machine Directive is effected by
means of the compilation of a check list which has been pre-prepared and is contained in the technical file.
The lists which are utilised are of three types:
•
List of dangers (as in EN 414 referring to EN 292)
•
Application of essential safety requirements (Machine Dir. 06/42)
•
Electrical safety requirements (EN 60204-1)
The following is a list of dangers which have not been fully eliminated but which are considered acceptable:
•
In the version of the pump without a release it is possible to encounter squirts of oil (for this reason appropriate protective
clothing must be worn)
•
Contact with oil -> see the requirements for the use of suitable personal protective clothing
•
Use of unsuitable lubricant -> the characteristics of the fluid are shown on the pump and in the manual (
in case of doubt
contact the Eng. Dept of Dropsa Spa
)
•
Protection against direct and indirect contact must be provided by the user
•
Given the purpose of the pump it must always be functioning; for this reason it is necessary to pay attention to the electrical
connections which, in the case of a power failure, the customer’s machine is restarted only by means of a reset, while the
lubrication pump is able to restart
INADMISSIBLE FLUIDS
