(1) Radiator
Attention
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.
Never use solvents of gasoline, benzine,
trichloroethylene and ketone for cleaning.
Check up and clean the radiator.
(2) Rotating section
(a) Supply Oil Seal
An scanner unit with 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.
