Ransburg RMA Dual Purge Direct A12300 - Manual (Page 66)

CLEANING SHAPING AIR
HOLES
In order to maintain uniform pattern control, the
shaping air holes of the inner ring and the shaping
air cap must be clean and free of any blockage.
It is best to leave the shaping air supply ON
during normal production break cleaning periods.
Shaping air can be reduced to 70 slpm during
this time. This will help material from entering
the passage ways.
Periodically (weekly) the outer shaping air cap and
the inner shaping air ring should be removed and
thoroughly cleaned. Use of an ultrasonic cleaner
would make cleaning of hole diameters easier.
Inspect all holes for blockage. Blow holes clear
with compressed air after some time of soaking
in solvent. DO NOT use any type of pick to clear
the holes. Damage may result to parts and could
affect performance of the equipment. If holes are
damaged (oversized holes, blockage, gouges) it
must be replaced.
