A3.14 Weather Covers
Weather covers provide additional protection against driving rain, intense
sunlight and other severe weather conditions.
Two options are available:
• Weather Cover 809881 mounts to the normal standpipe 703.020.
• A larger weather cover 807275 is required where the 4500 MkIII is
replacing an older 4500 MkII, Premier or MkII+ using the existing, large
standpipe.
In both cases, the weather cover mounts to the rear side of the standpipe
using the three studs and their lock nuts.
To open the weather cover for maintenance, undo the clamps on either side
and swing the cover upwards. To prevent accidental closing of the weather
cover, place a 6 mm or ¼ inch screw in the holes on either side of the fixed
part of the cover.
To prevent injury, always fit a locking screw in the weather cover before
working on the Model 4500 MkIII.
