(1) Radiator
Check up and clean the radiator.
(2) Rotating section
(a) Supply Oil Seal
When there is not a grease nipple, the replenishment of grease oil is unnecessary.
Remove the cap on the grease nipple located on the side of the X band radar or on the front of S
band radar at which the radiator is supported, 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.
(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.
Otherwise, the radiation plane may deteriorate.
