When using automatic dosing devices the following has to be observed :

·  Care for technically correct and controlled electrical grounding of the lubrication system

·  Avoid ingress of air when refilling the grease

·  Careful ventilation of the dosing equipment prior to initial operation

·  Use appropriate high pressure hoses of sufficient dimension, avoid narrow cable cross sections

·  Keep the lubricant pump pressure as low as possible

·  Avoid sudden ” pressure peaks ” when pumping

·  Equip the system with pressure control valves and blow out discs

·  Equip the system with a dry run safety system in order to avoid air suctioning

·  Contact the pump manufacturer with regard to the above measures

·  Observe the instructions given by the grease manufacturer in the corresponding safety data sheets and the operating instructions of the plant manufacturer
