Page 15: Tank Filling
8.4. TANK FILLING Refill the tank using the special device with filter. Proceed with filling, making sure that the maximum level line is not exceeded. If this happens, a leakage of lubricant from the vent channel, which acts as an air vent, will occur. During filling, air will be discharged directly from the hole in the vent channel itself. -
Page 16: Tank Filling (Spatula Version)
Check that the pump is running. Check that the machine is adequately lubricated (if there is any doubt as to whether it is working properly, contact the DropsA S.p.A. Technical department to request a test procedure). 10. Method of use There are no specific regulations, the pump is electrically powered by a system that controls its drive and operates the minimum level contact if the LTC board is not present. -
