FITTING UP AND STARTING A NEW ENGINE 



IN packing an engine for shipment it is usual to remove 

 the brass fittings to prevent their being stolen. These, 



together with the hose, governor belt and wrenches 

 are packed in a box. The rod for the flue scraper (and 

 the straw fork, for straw burning boiler), are placed in 

 the boiler tubes and the hose and funnel for filling the 

 boiler are placed in the smoke-box. The fire-box, ash- 

 pan, tubes and smoke-box should be examined to insure 

 the removal of all loose parts before the fire is started. 



Attaching Brass Fittings. In attaching the fittings to 

 the boiler, care should be taken to screw them in tightly 

 enough to prevent leaking. Brass expands more with heat 

 than iron, therefore where a brass fitting screws into iron, 

 the joint will be tighter when hot than when cold : conse- 

 quently should there be a leakage it should be stopped by 

 screwing the fitting in a little further when cold. In screw- 

 ing a pipe into a valve or other fitting, the wrench should 

 be used on the end of the valve into which the pipe is being 

 screwed. When the wrench is put on the opposite end, 

 the valve body is subjected to a twisting strain that is very 

 liable to distort and ruin the seat. The blow-off valve
