water or skim milk to clean last traces of cream from bowl and 

 from skimming pans. 



10. Clean the separator bowl before the milk sours in it. 



11. The separator bowl should revolve in the same direction 

 as the hands of a watch. 



12. Keep the milk float in supply pan when skimming. 



13. Turn faucet of milk supply can full open at once when 

 bowl is up to speed and allow full flow of milk to enter the bowl. 



14. Inspect the bearings and oil tubes before each skimming. 



Setting Up Power and Hand Separators. 



329. The smoothness with which a separator runs and the 

 efficiency of the skimming done by it, are both influenced by the 

 care and accuracy with which the separator is placed in position 

 to run. Some separator frames are placed on rubber cushions 

 enclosed in tin cases, one at each corner. A lag screw passes 

 through the center of the rubber and case with an iron washer 

 under it. These lag screws fasten the separator to the floor, but 

 they must not be drawn so tightly as to destroy the elasticity of 

 the rubbers. Lag screws may be made to hold firmly in a stone 

 or cement foundation by using just enough strips of leather for 

 filling the hole in the cement as to make the screw fit tightly. 



The separator frame ought to be raised somewhat above the 

 foundation in order to permit cleaning out the oil, milk and dirt 

 which accumulate under it. 



Leveling the Separator. 



330. When the frame is securely fastened to the foundation, 

 place the separator bowl in it. Then place an accurate level on 

 top of the bowl and turn the bowl slowly. This will show whether 

 or not the bowl is level at all points in the circle. If it is not, the 

 necessary adjustment may be made by placing thin pieces of wood, 

 tin, and even paper, under the corners of the frame where needed. 



331. The belt which connects pow r er separators to the inter- 

 mediate should make a straight line from the left side of the sepa-
