3. Maintenance and cleaning
3.1 Dismantling the collector-nozzle
Caution
Always deactivate the high voltage before starting any maintenance work and ensure
that it cannot be reactivated again!
The collector-nozzle 2 and O-ring 3 are parts subject to wear and must be checked regularly
(weekly) and replaced if the powder feed is inadequate.
The injector nozzle 4 should be checked at longer intervals and examined for wear.
Proceed as follows:
1. Disconnect all air connections and
powder hoses F/D/S from the
powder injector and remove from the
injector holder on the powder
container.
2. Loosen the outer nut 1 and remove the
collector-nozzle 2 from the
injector housing 5.
3. Clean the injector housing (blow out
with compressed air).
4. Loosen the collector-nozzle, check it
for wear and replace if necessary.
Parts subject to wear and spare parts are
listed in chapter 5
.
The condition of the collector-nozzle can
be checked by using the testing gauge.
Hint
The powder output can sink by 30% or more in relation to the set value due to collector-
nozzle wear.
