PITTING UP AND STARTING A NEW ENGINE 1$ 



engine has been run in the testing-room at the factory, and 

 it is probable that the bearings are properly adjusted. 

 However, they should be felt of at short intervals, and 

 should one of them heat to any extent, it will be best to 

 loosen it a little. The heating may be caused by grit. A 

 fast speed should not be attempted the first two or three 

 trips on the road, but the engine should be allowed to run 

 below its normal speed until bearings are smooth and the 

 operator becomes accustomed to handling the engine. In 

 order to keep the valve and cylinder well lubricated, during 

 the first few days it is necessary to use three or four pints 

 of cylinder oil in ten hours, the quantity depending on the 

 size of engine. Afterwards the amount may be lessened, 

 but it is essential that cylinder oil be fed continually.
