rator pulley over the top of the intermediate pulley and move 

 away from the separator so that the bowl turns in the direction 

 indicated by the arrow stamped on the bowl cover. The belt 

 must not be too tight, as the tight belt may cause the lower bear- 

 ings to heat and require an unnecessary amount of power to run 

 the separator. A tight belt may also increase the wear of the 

 bearings. When a flat belt is used the unpainted side should be 

 placed next to the pulleys. The upper side of the belt is tight 

 and the lower slack. A new belt should be put on in the evening 

 if possible so that it may be stretched over night. When the belt 

 becomes stretched by long use, the belt tightener should take up 

 the slack. 



Cleaning a Separator. 



332. A new separator bowl is often covered with a coating 

 of grease to keep it from rusting. This is cleaned by first wiping 

 off the grease from all parts of the bowl and the tin covers and 

 then washing them with hot water containing a little sal soda. 

 It is not often necessary to remove the bearings of the bowl or 

 the lower spindle of a new machine unless there is some defect in 

 the running of the separator. These bearings, however, must be 

 clean and bright, with no grit or threads left in them. 



Cleaning After Separating. 



333. When through separating, the bowl is first flushed out 

 with warm water before there is any reduction in its speed. This 

 will remove the cream frorii the bowl and from the cream cover. 

 The bowl is then allowed to stop or to "run down." Both the tin 

 covers, the float, and the faucet are then taken off and thoroughly 

 washed in a sink. This tinware should also be scalded, then placed 

 where it will be dry and not rust until used again. 



334. The separator bowl of power machines is nearly always 

 emptied by using a siphon. This must be done before the bowl 

 cover is unscrewed. After the liquid is all drawn from either a 

 hand or power bowl the cover is unscrewed (left Handed), by 

 using wrenches made for the purpose; the different parts of the
