Set the boom at about 65 degreesangle to the front end of car on operators right-handside, when the dipper will just clear ends of the work through the material as described inRight-of-way Ditching.

Widening a Side Hill Cut height of face of thematerial increases as themachine digs out fromthe track, it will benecessary to raise theboom and thereby raisethe digging radius ofclipper in making thenext cut through. Theboom and digging radiusof dipper will be lowereduntil grade line is reached. The degree of angle tothe car and the height at which boom is set after thefirst cut through depends upon the length of passnecessary to fill the dipper; this is governed by heightof face and nature of the material, also by ability ofoperator. In widening out the cut the boom willfinally be turned at right angles to the car, when thedipper will dig to the grade level, without under-cutting, approximately 20 ft. from center of track onwhich machine is working. This provides nicely forlaying a side track with a 14-ft. center. Do not try to dig the material down to grade tothe required distance from track center at one settingof the machine, or without moving forward each passof the dipper. If th
