MAINTENANCE (continued)
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 material from
entering the passage ways.
Periodically (weekly or sooner) 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 equip-
ment. If holes are damaged (oversized holes,
blockage, gouges) it must be replaced.
Inspect Bell Cup Daily
Check for signs of damage such as nicks,
heavy scratches, dents, or excessive wear.
Replace the cup assembly with any of these
conditions.
