3.
Remove the four screws (18) and washers (19) from the blade clamp ring (3),
lift off the ring and remove the blades (9).
4.
Remove the three screws (22) securing the cap and deflector assembly (5).
Pull the cap from the end of the gauze and push the spindle (2) through the
atomiser.
5.
If it is necessary to remove the gauze, insert a screwdriver through the holes in
the rear of the gauze and take out the three screws (20) securing the gauze to
the hub.
6.
If it is necessary to remove the bearings, use a pair of circlip pliers to remove
the circlip (17) from the front of the hub. Next, push an aluminium or brass drift
against the inner part of the rear bearing and tap both bearings out through the
front of the hub. Ensure that the hub (1), spacers (6 and 7) and ring (10) are
not damaged or lost.
After dismantling the atomiser, the following must be checked:
Gauze (4)
Bearings (13)
Tolerance rings (16)
Bearing spacers (6 and 7)
V-Ring seal (14)
Nilos ring (15)
Any worn and damaged parts must be replaced with genuine Micronair spares. Any
attempted repair of parts or the use of substitute parts could seriously damage the
sprayer and impair its performance.
The procedure to re-assemble an atomiser is the reverse of the dismantling
procedure. It is important that the following points are observed:
1.
A new Nilos ring should always be fitted when the bearings are replaced.
2.
Fill the recess of the Nilos ring and brass sealing ring with grease. The
bearings, spacers and lip of the V-Ring should also be coated with a thin film of
grease before assembly.
3.
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.
4.
The clamp ring (3) must be assembled in the correct position with the dimples
in the ring and hub body aligned.
