HOIST LOWER STOP With upper arm extended to the side, forearm and index finger pointing straight up, hand and finger make small cirdes. With arm and index finger pointing down, hand and finger make smal cirdes. With arm extended horizontally to the side, palm dovwn, arm is swung back and forth. BOOM UP BOOM D OWN EMERGENCY STOP SWING With arm extended horizontally to the side, thumb points up with other fingers dosed. With arm extended horizontally to the side. thumb points down with other fingers dosed. With both arms extended horizontally to the side, palms down, arms are Swuna back and forth. With arm extended horizontally, index finger points in direction that boom is to swing-
