Incorporate the motor on the radar
antenna.
Press the motor against the butting part of
the mounting arm from the cabinet, make
adjustment so that the backlash becomes
minimum, and secure the motor.
Tighten the hexagon head bolts at a
proper torque (140 kgfcm) to ensure that
there are no tightening omission and
looseness.
After incorporating the motor, apply grease
to the gears.
Connect cables to the drive circuit in the
original state.
Before mounting the cover on the radar
antenna, confirm that there are no
abnormalities such as deformation and
crack on the cover packing.
Remove any foreign matters, dust or other
contaminants if found.
The cover is secured with four hexagon
head bolts (M8).
Tightening omission and looseness of the
hexagon head bolts adversely affect
waterproof performance. Tighten the bolts
at a proper torque so that there are no
tightening omission and looseness.
