BOOM GRT9165 SERVICE MANUAL
You can turn the drum by pulling the RCL cable in the
direction of the main boom head. If you let go of the cable,
the drum turns back because of the initial tension.
6. Check to make sure all screws (1) are tight.
7. Put the casing (2, Figure 4-13) back in place. Make sure
that the seal is in the right place.
8. Fasten the casing with all the screws (1).
When all the cable has been wound on the drum it needs to
stay on the drum while you are doing the 8 ± 1 revolutions of
pre-tension on the entire reel, then start pulling the cable off
to route out alongside the boom section.
