Safety Instructions
—
The staff members in charge of the repair/maintenance work are obliged
to carefully read and observe all the instructions indicated in this
operating manual.
—
All maintenance or repair work will have to be carried out only after
having depressurized and cleaned the spray gun. Otherwise, serious

may occur.

Remove the O-ring for the silencer ring (1/51).
—
Pull the silencer ring (1/50) off the air converter (1/19).
—
Place the silencer ring on your flat hand and blow into it; if you
determine a considerable resistance or if no air at all will go through, the
silencer ring cannot be used any longer and will have to be replaced.
—
Put the checked or new silencer ring on the air converter.
—
Install the O-ring for the silencer ring on the air converter and lock it
within the groove.

Replacement of Nozzle & AKKORD Needle, Adjustment of Initial
Air Input Settings
1. Disassembly of the existing nozzle set
—
Loosen the material fine adjustment device (1/39) by means of an
open-jawed wrench (jaw size: 22 mm) and remove it.
—
Remove the AKKORD needle (1/47) carefully and take care not to
spoil it by bending.
—
Remove the nozzle cap adjusting ring (1/1).
—
Take the nozzle cap (1/2) and the nozzle cap diaphragm (1/3) out of
the spray gun.
—
Unscrew the nozzle (1/4) counterclockwise by means of a deep offset
wrench, a wrench or a nut (wrench size: 13 mm) and remove it from
the nozzle holder (1/7).
Do not use an open-jawed wrench or tongs for mounting or
dismounting the nozzle, because these types of tools may damage
the nozzle or the spray gun body. It is possible that such damages
completely destroy the spray gun.
