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
