4.2.5. Opening the radome temporary
This requires another people on the opposite side. When open radome temporary, use long
threaded bolts to secure the upper radome for maintenance work if it is not possible to remove
the upper radome. This bolt set is in the maintenance tool box. Put these bolts from bottom holes
to the fixed nuts on the upper radome. To hold up the upper radome in balance, bolts should be
distributed evenly.
Caution: DO NOT open the upper radome during strong wind or radome may become airborne,
causing harm to individual(s) or radar.
(1) Loosen all 12pcs M10 bolts which will retain
on the bottom radome for fall prevention.
(2) Rotate upper radome 10 degrees counter
clockwise until M10 bolts fit to the recess
holes in order to align thru-hole on radome
base with nut insert on upper radome.
(3) Insert threaded bolts, with nut setup 10mm
from the end, into each thru-hole from
bottom radome to upper radome nut insert.
(4) Lift up the upper radome until M10 nut
contacts radome base and hold it.
(5) Attach a spring clamp on each threaded bolt
to secure all bolts.
