HANDLING THE ENGINE 6l 



a smooth straight road without turning the wheel at all, 

 but in practice it is always necessary to turn it a little. It 

 is important to keep your eye on the front wheels of the 

 engine. 



Setting the Engine. A little practice is necessary to 

 enable the operator to quickly line and set the engine, but 

 this is acquired by most men in time. On a calm day the 

 engine and the separator should be "dead in line," that is, 

 in such a position that a line drawn through the edges of 

 the fly-wheel rim would pass through the edge of the sep- 

 arator cylinder-pulley rim on the same side, and a line 

 drawn through the edges of the cylinder-pulley rim would 

 pass through the edge of the fly-wheel rim on the same 

 side. 



Whew threshing on a windy day, the drive belt should 

 be crossed so the slack side will be toward the direction 

 from which the wind is coming. When crossed in this 

 way, the pulling side (that is, the one going to the bottom 

 of the engine fly-wheel) will support the slack side and in 

 a measure prevent it from being carried out of line by the 

 wind. Allowance for the wind must be made, a heavy 

 side wind requiring a setting of the engine sometimes as 

 much as two feet out of line. When the rig has been set 

 during a calm and a wind comes up, it is not necessary to 

 stop, throw the belt and reset the engine in order to make 

 the belt run on the pulley. Take a screw-jack or lifting- 

 jack, set it obliquely under the front axle of the engine 

 and move it in the direction the wind is blowing until the
