Striker Torque multiplier Hand cleaner/spray silicon Lubricant Obtain shearer from the track with duck bill scoop Position two duck bill scoops, one on each side of track, with the bills facing the track Instruct the motorman to position the shearer so that the end of the shearer is even with the outby corner of the crosscut Set torches up See cutting and welding plan Cut shearer free of transport car Place duck bill under the shearer trapping shoe and sprocket near the outby end When this shearer is being unloaded, the control panel covers must be on the inby side when taken to the face Instruct the motorman to tram toward scoop at the same time the scoop will tram into the crosscut This will swing the shearer to the position for transport Stop the motorman and scoop operator when the shearer is parallel with crosscut  Place the duck bill of the second scoop under the trapping shoe and sprocket on the opposite end When this shearer is being unloaded, the control panel covers must be on the inby side when taken to the face Lift shearer off the car with both scoops Secure the shearer body with scoop winch rope Instruct motorman to transport car from under the shearer Tram scoops with the shearer to pan line, push the shearer and lead scoop with the trailing scoop These two operators have to work together Communication between the two operators is critical The lead scoop is only to assist as needed Stop at notch Shut scoops down Crib the headgate end of the shearer with six crib blocks about 18" off the bottom Lower the shearer on to the cribbing Unhook the scoop winch line Install ranging arms, cutter drum, and water spider See Duty No. 17 Install shearer on pan line Install piece of accu-trac onto the existing pan line leaving one end loose This is to be use as a guide pin Set duck bill scoops One scoop on the headgate end One scoop on the tailgate end of shearer Lift the headgate end of the shearer off the bottom Tram the scoop forward toward the head drive until the trapping shoe is aligned with accu-trac You may have to lower or raise the scoop to engage the trapping shoe onto the accu-trac Use tailgate scoop to push the entire shearer toward the headgate engaging the trapping shoe on both ends You may have to lower or raise the scoop to engage the trapping shoe onto the accu-trac Install tailgate ranging arm, cutter drum, and water spider See Duty No. 17 Remove all debris and materials Duty 17:  Install Ranging Arms, Headgate Cutter Drum, and Water Spider Conduct exam Obtain and examine tools and materials Chisel Hammer
