Always look over belts and everything in the afternoon, so 

 as to be ready for the morning work. A leaky valve or union 

 left to drip day after day is a "dead give away" of the maker as 

 a careless one. Here as elsewhere, "a stitch in time saves nine." 



Belts should be wide enough and long enough and pulleys 

 large enough to allow them to pull without being too tight. They 

 never work as well in a vertical as in a slanting, or better still, 

 horizontal position. The lower side should be the pulling one. 

 (See Fig. 87). If they slip apply a little belt grease (not too 

 much), and keep them soft with a coat of it now and then. Only 

 in emergency should powdered rosin be used. Protect leather 

 belts againts moisture; if that is impossible use rubber. 



A common fault in creameries is too light shafting. It is poor 

 economy. 



RUNNING THE SEPARATOR. 



The separator, running at the high speed it does, is a delicate 

 piece of machinery and requires more care than is usually given 

 to it, which often does not exceed that given a chaff-cutter or 

 threshing machine. For the hand separators, some of the follow- 

 ing pointers for running power separators hold good. 



See that your 



separator is level 

 and follow the 

 directions of 

 the manufacturers 



- 87) closely. Before 



starting be sure that they are put together right, that in the 

 "Alpha" the riglet plates are in the right order in the right bowl 

 and the right bowl in the right frame. 



Watch all parts liable to wear such as the bearings and the 

 rubber, which should be renewed whenever it loses its elasticity. 

 The threads in the bolts in the plate that holds down the rubber 

 ring should be watched as the loosening of this plate may cause 

 an accident. In putting a new rubber ring in the upper bearing a 

 little of it may be squeezed under the plate and this may cause the 

 loosening of the screws. 



See that all oil cups are rilled with the very best oil and in 

 good working order. 



Don't forget to fill the bowl with water and to start slowly.
