CASTING AND FILLING THE DRAGLINE BUCKET
CASTING THE BUCKET ADDS 10 TO 20 FEET TO THE EFFECTIVE DIGGING RADIUS. PULL THE FRONT DRUM
LEVER AND RAISE THE BUCKET HALF THE DISTANCE BETWEEN THE GROUND AND THE BOOM POINT.
DEPRESS REAR DRUM BRAKE AND RELEASE THE LEVER. PULL FRONT DRUM LEVER AND PULL BUCKET IN
TOWARD THE BOOM, THEN SIMULTANEOUSLY RELEASE LEVER AND BRAKE PEDAL ALLOWING BUCKET TO
CAST OUT BEYOND THE BOOM POINT. ACCURATE CASTING WILL COME ONLY WITH PRACTICE. AFTER THE
BUCKET HAS BEEN CAST, PULL THE FRONT DRUM LEVER BACK, DRAGGING THE BUCKET TOWARD THE
MACHINE. EASE UP ON THE REAR DRUM BRAKE PEDAL ALLOWING THE HOIST CABLE TO REEL OFF THE
DRUM SO THE BUCKET TEETH CONTINUOUSLY BITE INTO THE GROUND. WHEN BUCKET IS FULL, RELEASE
THE FRONT DRUM LEVER AND DEPRESS BOTH BRAKE PEDALS.
RAISING THE LOADED BUCKET
PULL THE REAR DRUM LEVER BACK AND RELEASE THE REAR DRUM BRAKE PEDAL. EASE UP ON THE FRONT
DRUM BRAKE PEDAL TO HOLD THE BUCKET LEVEL AND PREVENT DUMPING AS THE BUCKET IS RAISED.
WHEN BUCKET REACHES DESIRED HEIGHT, APPLY REAR DRUM LEVER. ALSO, APPLY FRONT DRUM BRAKE.
