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, benzine, trichloroethylene and ketone for
cleaning.
Otherwise, the radiation plane may deteriorate.
Check up and clean the radiator.

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 Mobilux 2 of Mobil Oil.
