1. Disconnect all hoses and remove sprayhead from the sprayer. Plug all free ends of
hydraulic hoses on the sprayer and all ports on the hydraulic motor.
2. Remove atomiser (1) by unscrewing screw (7).
3. Remove frontplate (10) complete with distributor (15) by unscrewing twelve
screws, nuts and washers (2,8,4) and four screws, nuts and washers (6,8,4).
4. Separate feed tube (34) from straight connection (27) fitted in the distributor by
pushing down on the top of the straight connector and pulling the feed tube out of
it.
5. Lift the front plate complete with distributor free of the main body and put to one
side.
6. Remove front shaft (14) and fan (21) from the main unit by undoing four capscrews
and washers (39,3). These two parts should be only a sliding fit on the hub (12)
and can be removed easily. (If the front shaft proves difficult to remove then a very
long M6 setscrew (or piece of M6 threaded bar) can be used as a puller by screwing
into the end of the front shaft and reacting against the end of the screw (33) inside
the hub).
7. Remove two off drive pins (40) and two pairs of lock washers (41).
8. Next remove the hub (12) from the bearing by unscrewing the four grubscrews (13)
and pulling the hub off by hand, or with the aid of a universal bearing puller.
9. Remove the hydraulic motor (22) complete with bearing (23) and shaft extension
(42) by undoing four screws, nuts and washers (6,8,4).
10. The bearing (10) can be removed from the motor by the use of a brass or
aluminium drift or a universal bearing puller. The bearing should only be removed
if it requires replacement.
11. The shaft extension (42) can be removed from the motor by removing the capscrew
(33), lock washer pair (37) and plain washer (38). The shaft extension can be
removed using either a suitable brass or aluminium drift or a small universal
bearing puller. Take care to retain the key in the motor shaft for future use. The
shaft extension should only be removed if it is either to be replaced or if
maintainence is necessary on the hydraulic motor involving the removal of the
hydraulic motor main shaft.
12. The motor support bracket (31) and rear guard (36) can now be removed if
necessary by undoing all remaining M6 screws and nuts (8,6,4,2).
