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.
Rotating section
Supply oil seal
For machines without a grease nipple, the replenishment of grease oil is unnecessary.
For machines with a grease nipple, 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 Scanner unit 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.
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.
