7. Lock the two column clamps, tighten the converter housing door screws,
and then tighten the fixture on the base plate.
8. Check for proper mating of fixture, parts, and horn. If the horn and part are
not in parallel contact, shim the fixture or adjust leveling screws as
required.
9. Set the PRESSURE regulator to a reading of 20 psig (140 kPa/1.4 bar) on
the pressure gauge. (Turn the PRESSURE knob clockwise.)
10. To check that the horn and parts are properly aligned, the horn needs to
be lowered. Read through the Operation instructions on the next page, and
then proceed to lower the horn as detailed. If the horn and parts are not
sufficiently aligned, then repeat steps 4 through 8 on the preceding page.
However, if you are working with small, delicate parts, then fine
adjustments can be made using the positive stop adjustment knob as
explained below.
POSITIVE STOP ADJUSTMENT
The positive stop is set to limit the downward travel of the horn to
approximately 75%. Readjustments may be required. Coarse adjustment of
the clearance between the face of the horn and part should be made using
the elevation control. Fine adjustment should be made using the positive stop.
The positive stop adjustment knob is located offset from the converter
housing. Turning the knob clockwise will decrease downward travel distance.
Turning the knob counterclockwise will increase the downward travel
distance. A set screw located on the left side of the housing locks the positive
stop adjustment in place. Use a 3/32 Allen wrench to lock and unlock this set
screw.
NOTE: For maximum
safety and productivity,
adjust the clearance
between the horn and
the part to a minimum
that will still allow ease
of loading and
unloading.
