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 peri-
ods. Shaping air can be reduced to 70 slpm
during this time. This will help stop material
from entering the passage ways.
Periodically (weekly) the outer shaping air cap
and the inner shaping air ring should be re-
moved and thoroughly cleaned. Use of an ul-
trasonic cleaner would make cleaning of hole
diameters easier. Inspect all holes for block-
age. 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, gauges)
it must be replaced.
