STARTING AND SETTING A SEPARATOR 



about twelve feet apart, it is easy to calculate how much 

 the front or rear wheels must be lowered to bring the ma- 

 chine level. For example, if a spirit level two feet in 

 length be used and the axles are twelve feet apart, then one 

 axle must be lowered or raised just six times as much as 

 the end of the level. If, when placed on the sills, the front 

 end of the spirit level requires raising, for example, one- 

 half inch, then the rear wheels must be lowered six times 

 as much, or three inches, to bring the separator level. This 

 method may also be used in determining the amount to 

 lower one rear wheel to bring machine level crossways, 

 which, as already stated, is more important than having 

 it level lengthways. In this case, however, the amount in 

 comparison with the amount shown by the level is different 

 for each size of separator. The hole or holes should be 

 dug before the engine is uncoupled or the team unhitched, 

 so that if not level, machine may be pulled out, the holes 

 changed and the machine backed into them. When the 

 machine is high in front, it can be quickly leveled, after 

 engine or team has been removed, by cramping the front 

 axle, digging in front of one wheel and behind the other, 

 so that wheels will drop into the holes when pole is brought 

 around square. 



.With geared machines "bolster- jacks" are used to keep 

 the "side-gear" from twisting front end of machine out of 

 level. The hind axle being level, place the bolster- jacks 

 in position, and screw them up so as to level the front of
