of hose Call headgate/tailgate to have air turned on Flush air line Hook up to oiler Band in place Fill oiler with air tool oil Hook shield water  to drill With 50' hose, tap on each shield, move as needed Grease drill head as needed Installing roof support Conduct exam Set temporary jacks Set jacks on unsupported side of shield Keep your body under supported roof Conduct gas test Gas test must be made every 20 minutes Set gopher drill between temporary support Test the roof, sight, sound and vibration prior to drilling Keep your body under supported roof Set drill on the face side of pan

to scoop using the winch cable Store drive in designated area See longwall move plan 6:  Installing Pan Line Pinner with Duck Bill Conduct Exam Place pan line bolter on scoop Drill head must point away from the scoop operator Place bolter trapping shoe 12" to left of center hole on duck bill Bind the bolter with winch cable Tram the scoop to pan line at the tail gate Lower pinner to bottom Back out from under bolter until trapping shoe drops off of duck bill Move scoop forward Place duck bill on top of trapping shoe Move scoop forward until duck bill comes in contact with trapping shoe pin Lift the bolter up until the trapping shoe is even with the accu-trac Push bolter on pan line with scoop Take scoop binding cable off Remove scoop Lock out/Tag out #6 cable from the distribution box at the headgate Follow Lock Out/Tag Out Procedures Splice the pinner cable Must be done by qualified electrician Turn the power on to #6 cable Check rotation 7:  Installing Pan Line Pinner with Bucket Scoop Conduct Exam Place pan line bolter on scoop Place bolter on the left side of scoop bucket drill head pointing away from the scoop operator Hand rail of he pan line would be in the way Pan line can be slewed with the ram Bind the bolter to the scoop bucket with the winch cable With the scoop bucket there is virtually no chance of the pinner falling off or sliding Tram to the pan line Drop the bucket Loosen the winch cable Back out from under the bolter until the trapping shoe drops below bucket Tighten cable back up until bucket comes on top of trapping shoe Raise bolter up to align with pan line May have to slew pan line Push the bolter on the pan line with the scoop ram Remove scoop binding cable Remove scoop Lock out/Tag Out #6 cable from the distribution box at the headgate Follow Lock Out/Tag Out Procedures Splice the pinner cable Must be done by qualified electrician Turn the power on to #6 cable Check rotation
