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, lint-free cloth.
•
check that the radar components are held securely in place and that the screws, nuts and
bolts have not worked loose. Tighten and re-apply marine paint where necessary to prevent
corrosion.
•
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 lint-free cloth dampened with alcohol or water. Do NOT use petrol, gasoline,
benzene, thinner, or similar solvent to dampen the cloth as these cause deterioration of the
external surfaces.
•
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.
