Spring Tension the Reeling Drum
Ensure the reeling drum spring is properly pre-tensioned by following the procedure below:
1. Fully retract the boom assembly and remove the reeling drum cover.
2. Slowly rotate the Reeling Drum clockwise until you hear a “click”, indicating the power spring
clutch is engaged.
3. Turn the Reeling Drum counterclockwise five (5) complete turns and physically restrain it from
moving.
4. Remove enough cable from the drum (about three wraps = 10 feet) to reach the boom tip.
Leave enough extra cable to reach the Anit-Two-Block hardwire and relieve the strain on the
cable.

Pre-tensioning of the Reeling Drum is complete.
