Locking System Setup
Refer to Figure 19
The TSF1060 and TSF1260 have a locking system for
automatic boom locking during folding and transport. For
proper folding, the boom-lock cable must be tight enough
that the lock arms just clear their stops when unfolded
and rest secure against the stop when folded.
Refer to Figure 20
To adjust the tension on the boom-lock cable, loosen jam
nut and turn clevis.
Re-tighten jam nut.
