(1) Radiator
Check up and clean the radiator.
(2) Rotating
section
(a) Supply
Oil
Seal
An S-band scanner unit without a grease nipple needs grease supply. Remove the cap of the grease
nipple on the front of the radiator support, and supply 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.
(b) 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) Mounting
legs
Check the mounting legs and mounting bolts of the scanner 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.
z
If the radiator front face (radiation plane) is soiled
with smoke, salt, dust, paint or birds’ droppings,
wipe it with a piece of soft cloth wetted with alcohol
or water and try to keep it clean at all times.
Otherwise, radar beam radiation may attenuate or
reflect on it, resulting in deterioration of radar
performance.
z
Never use solvents of gasoline, benzine,
trichloroethylene and ketone for cleaning.
