MICRONAIR AU8000 SPRAYER
After dismantling the atomiser, the following should be checked:
Gauze (104) – Free of dents or chemical contamination
Bearings (113) – Both in good condition. If one bearing is faulty, both
must be replaced
Tolerance Rings (116) – Not cracked or deformed
Bearing Spacers – Not corroded or worn
(106 and 107)
V-Ring Seal (114) – In good condition and not cut or worn
Nilos Ring (115) – Not worn or bent
Any worn and damaged parts must be replaced with genuine Micronair spares. Any
attempt at local repair or the use of substitute parts could seriously damage the unit and
impair its performance.
The procedure to re-assemble the atomiser and sprayhead is the reverse of the
dismantling procedure. It is important that the following points are observed.
1. Fill the recess of the Nilos ring and the brass sealing (110) ring with grease. The
bearings, spacers and lip of the V-Ring should also be coated with a thin film of
grease before assembly.
NOTE: When new bearings are fitted a new Nilos ring should be fitted.
2. The bearings must be pressed squarely into the hub and must not be allowed to
become mis-aligned. They must NOT be driven in with a hammer.
3. The clamp ring (103) must be assembled in the correct position with the dimples in
the ring and hub body aligned.
NOTE: Item numbers 1 – 20 refer to Fig. 5 and item numbers 101 – 122 refer to Fig. 6.
