The oil that has been pumped from the tank passes through felt q where it is filtered, and is fed into the case through nozzle w. When the volume of oil reaches a certain level, float e ascends, valve t descends via lever r, nozzle w closes, and the feeding of oil stops, thus completing the oil feeding process. When the oil inside the case is consumed, float e descends, valve t ascends via lever r, allowing oil to be fed from nozzle w. If the pressure is discharged, the oil could flow back if the operating pressure differential range (the differential between the tank and line pressures) exceeds 0.6 MPa. Therefore, make sure to also discharge the tank pressure. Install the float vertically inside the bowl so that it will not come into contact with the siphon tube, preventing the oil from dripping poorly. Oil cannot be fed into Auto Feed Lube under being pressurized. We recommend oil is supplied from cam handle (plug for oil supply) of an auto feed tank. Operating Pressure Range Tank and line pressure Tank pressure (MPa) Operating allowable range Line pressure (MPa) (2) (1) Tank pressure is removed when line pressure is stopped. Tank pressure is kept same when line pressure is stopped possible to use. Note 1) Note 2) Series ALF400 to 900, ALT-5/-9 How to Order 952
