20. Sump the cutterhead into the face by pushing tram levers forward. Tram machine forward until it has advanced approximately 20" into the top of face. 21. Lower cutting head down, thus shearing the face. Do not tram during the shearing cycle. 22. When head has reached bottom, release shear switch, raise stabilizer shoe and tram machine backward approximately 24" thus trimming ridges and smoothing bottom. Make certain shuttle car is clear before backing miner. 23. Raise the cutterhead and repeat cycle (19 thru 22) until desired amount of face has been cut. 24. Turning crosscuts is accomplished by making a

series of partial cuts until the machine can be turned to the desired angle.
