11 Maintenance
Before doing any maintenance work, always ensure that the radar system is turned OFF at the main power source.
If a rectifier unit is used, turn OFF the power supply to this too. Remember that high voltages from the rectifier unit are always present, even if the radar is not operating, and these can cause severe injury or death.
11.1 General maintenance
Proper maintenance of the radar system will keep it in good condition and minimize breakdowns. Periodically:
•remove any dust, dirt, or sea salt from the external surfaces with a dry,
•check that the radar components are held securely in place and that the screws, nuts and bolts have not worked loose. Tighten and
•check that all the radar cabling is not frayed, bent, or cut and that the radar system cable connections are secure, tight and waterproof.
11.2 Scanner maintenance
Before working on the scanner, remove your watch and any magnetic cards, because the modulator circuit in the magnetron emits a strong magnetic field that can badly affect such items
•Remove any dust, dirt, or sea salt from the external surfaces, particularly the front side of the scanner, with a
•At least once every six months, apply grease (Mobilux 2 or equivalent) evenly to the lubricating gears, with a brush or knife. More frequent application is desirable to maximize the life of the lubricating gears.
•The drive motor brush has an expected life of 2,000 hours. Replace it when half of the overall length has worn away. The drive motor carbon brush can be removed easily by unclipping the two caps located on both sides of the bottom part of the drive motor.
•Clean any carbon powder off the drive motor commuter with a dry brush or, if this will not remove it, use sand paper #250 to #400.
