residual powder. The cleaning takes place in
the following steps:

on the Venturi pump.
2. Blow through the hose manually with com-
pressed air to blow loose powder through
to the applicator.
3. Fit the powder hose onto the hose connec-
tion on the injector.

the shaping air ring. Clean on the inside
with compressed air and remove possible

contact powder.
3. Follow “Daily Cleaning” steps.
4. The powder supply is to be filled with pow-
der just before resumption of the opera-
tion.

and replaced if:
•
Uneven powder distribution on deflector as
compared to starting
•
The spray pattern no longer has a regular
form

worn
•
The wedge of the electrode holder wear
bar is worn down to the electrode holder
