Radiator
Note:
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.
Check up and clean the radiator.
Rotating section
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.
Driving motor
i) Attenuator
Greasing is not necessary unless there is oil leakage.
ii) Motor
The life span of the brush itself is 2000 hours. When the brush is worn out to a half
of the entire length, replace it.
The communicator must be kept clean all the time. If carbon dust is stuck and cannot
be removed with a dry cloth, polish the section with sand paper of No.150 to 400.
The carbon brush can be removed by removing the caps on both sides of the bottom
of the motor.
