c. Rotating section
c-1 Supply Oil Seal
The scanner unit NKE-1130 (JMA-9132-SA) and NKE-1139 (JMA-9133-SA)
with a grease nipple needs grease supply. Remove the cap on the grease nipple on
the front of the radiator support, and grease with a grease gun. Make the oiling
every six months. The oil quantity shall be approximately 100 g, which is as
much as the grease comes out of the oil seal. Use the grease of Mobilux 2 of
Mobil Oil.
c-2 Oiling gears
Apply grease evenly to the tooth surfaces of the main shaft drive gear and the
encoder drive gear with a spreader or brush. Oiling in short intervals is more
effective to prevent the gears from wear and tear and extend their service life, but
oil at least every six months.
Use Mobilux2 of Mobile Oil.
c-3 Mounting legs
Check the mounting legs and mounting bolts of the antenna unit case for corrosion
at intervals and maintain them to prevent danger. Apply paint to them once a half
year because painting is the best measure against corrosion.

8.2.3 Coaxial Cable (JMA-9133-SA)
The coaxial tube gland of a coaxial cable terminal is fully waterproofed when
installed. To prevent a water leakage accident, periodically inspect the coaxial
tube gland. In particular, the coaxial tube gland should be repainted every six
months.
ā¢ Install flexible wave guide without any clearance. Leaving a
clearance may cause water leakage or corrosion later.
