82 CANADIAN DAIRYING. 



the milk may have been allowed in the bowl before 

 speed has been reached. The remedies suggest them- 

 selves. In case of the spindle being bent or the bowl 

 out of balance, these parts would have to be returned 

 to the manufacturer. 



2. The cream too thick Caused by the feed being 

 too little ; the speed may be too great for the feed ; 

 the milk may be too cold or too rich for the adjust- 

 ment ; or the cream outlet may be too small. So long 

 as the cream will flow freely from the cream spout, it 

 is not advisable to change the adjustment or cream- 

 screw, unless in special cases. 



3. The cream too thin Caused by the feed being 

 too large for the speed or adjustment ; the speed too 

 low ; the outlet may be too large ; or the skim-milk 

 tubes may be clogged, which would cause too much 

 skim-milk to pass out with the cream. 



4. The separation not complete May be caused by 

 lack of proper speed ; the milk may be too cold ; the 

 feed may be too great, especially where the float does 

 not work properly ; the machine may be vibrating ; 

 the cream outlet may be partially clogged ; or the 

 machine may be defective. 



5. Milk in the frame may be caused by the covers 

 not fitting properly ; the joint of the bowl may not be 

 tight ; or the bowl may be too low for the skim-milk 

 and cream to be properly delivered in the covers. 



6. If the machine runs heavily the oil may not be 

 good ; the bearings may be gummed, in which case 

 use kerosene oil ; the separator may not be level ; the 

 bowl may be out of balance ; or the gearing may be 

 defective.
