10.2. Appendix 2. Changing the SECTOR II to a left-hand
configuration
10.2.1. Changing over the
internal spring assembly
Follow the steps below to change the
barrier orientation as required by
the site.
Removing the internal spring
assembly
Step 1
Place the boom pole in the upright
position.
Remove the pole by
removing the M8 nuts (refer back to
Figure 16).
Step 2
Use a 24mm socket (4.5 and 6M
boom) or a 17mm socket (3M boom)
and a ratchet spanner to relax the
tension on the spring by unwinding
the nut in an anti-clockwise
direction. Continue until there
is no more tension in the spring
whatsoever (Figure 43).
Step 3
When the spring is completely loose,
rotate the taper roller at the bottom of
the spring assembly 90° (Figure 44).
This will allow you to lift the entire
spring assembly out.
