What is the correct way to bleed a system on startup?
(See Bulletin #30103) The most thorough and efficient method to purge the trapped air in a Series-Progressive distribution system is to start at each lubrication point and work back toward the central pumping source, purging each line and feeder assembly in reverse order. On a parallel system, the plug at the last manifold in each branch line should be loosened and all air purged from the main lines. Tighten the previously loosened plugs and cycle the system until all bearing feed lines are full and purged of air.
