• Boom must be directly over the front with house lock engaged.
• Fully retract the boom and set boom angle to 0°. Remove the quick reeve pin on the boom nose, remove any reeved wire
rope laying it off to the right side of the boom and place the rigging down on the ground in front of the crane. The boom
