Chapter 7 Maintenance
7.1 Regular service and cleaning up
Periodic inspection and cleaning is essential to keep the radar system in the good working order
for the life of the radar.
7.1.1 Monthly inspection
(1) Check whether there is any dirt or soot on the radiating part of the Antenna unit. If any, wipe it
with soft cloth soaked in water or soap detergent. Also make sure no cracks or coating material is
on the front radiation part of Antenna unit.
(2) Wipe the radar screen with cloth soaked in static electricity inhibitor if dirty. Avoid using a dry
cloth since it will generate static electricity resulting in the accumulation of dust.
7.1.2 Annual inspection
Inspect the antenna motor brushes in the Scanner unit every 2,000 operating hours. Replace with
a new brush if the brush length is less than 6 mm.
(1) Remove the cover at the forward side of the Antenna unit by unscrewing the mounting screw.
The antenna drive motor is located inside the lower side of the housing.
(2) Remove the old motor brush using the slotted screwdriver. (Refer to Figure 7.2).
(3) Fit the screw to the slot and rotate slowly to counter clockwise. Both of the brushes should be
changed simultaneously.
(4) Insert new brushes and rig them with a reverse sequence.
Never turn on the power of radar system under inspection.
To prevent electric shock, be sure to turn off the radar system power
before opening the cover of the Antenna unit.
