(Dis-)Assembly of Nozzle Holder , Replacement of Sealing Ring
1. Remove the nozzle set according to the instructions indicated in chapter
9.2.3 Replacement of Nozzle & AKKORD Needle, Adjustment of Initial
Air Input Settings , page 9-22.
2. Screw the mounting bolt, belonging to the scope of supply of your spray
gun, in the nozzle thread of the nozzle holder (1/7).
3. Clamp the other end of the mounting bolt into a vise, so that the thread
connection piece for paint (1/29) is on top.
4. Loosen the thread connection piece for paint by means of a 17 mm-
wrench and remove it. Do not use an open-jawed wrench, since the
thread connection piece is only glued on and the force exerted by such
a wrench will be too high. The hexagon nut of the thread connection
piece for paint could be damaged, and if the wrench slips off, the air
hose connection piece (1/28) may break off.
5. Pull the spray gun body off the nozzle holder to the rear side. If this does
not work well, slightly hit on the front edge of the spray gun body by
means of a plastic tip hammer to work loose the spray gun body for an
easy removal from the nozzle holder. Do not use a fitter's hammer, you
might damage the spray gun body thread!
6. Unscrew the nozzle holder from the mounting bolt.
7. Unscrew the blocking screw (1/5) on the rear side of the nozzle holder
by means of an appropriate screw driver.
8. Remove the old sealing ring (1/6) from the nozzle holder.
9. Clean the drill hole by means of the long cleaning brush and remove all
paint residues and impurities.
10. Clean the blocking screw and remove all residues and impurities.
11. Take the AKKORD needle and push the blocking screw on the
AKKORD needle from the front side with the slotted end first.
12. Carefully mount the new sealing ring on the AKKORD needle with the
closed side first.
13. Insert the accordingly equipped AKKORD needle into the nozzle holder
from the rear side and push the sealing ring and the blocking screw into
the drill hole as far as possible to be able to fasten the blocking screw.
14. Screw in the blocking screw by hand until the limit stop and pull out the
AKKORD needle.
15. Tighten the blocking screw by means of the screw driver.
