Section 21 Maintenance & Inspection 21-24
21.3.1.2 Radiator
Perform inspection and cleaning of the radiator.
Note
• 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, benzene, trichloroethylene and ketone for cleaning.
Otherwise, the radiation plane may deteriorate.
21.3.1.3 Rotating section
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 front of the part at which the radiator is supported,
and grease with a grease gun. Make the oiling every six months. The oil quantity shall be approximate
100 g, which is as much as the grease comes out of the oil seal. Use the grease of Mobilux2 of Mobil
Oil.
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 the grease of Mobilux2 of Mobil Oil or equivalent.
Mounting legs
Check the mounting legs and mounting bolts of the radar antenna chassis 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.
21.3.2 Flexible wave guide (JMR-9225-7X3/9X3,
JMR-7225-7X3/9X3)
Note
Install the flexible wave guide without any clearance.
Leaving a clearance may cause water leakage or corrosion later.
