Fin Position on the WideSpread Spinners
For most products, there will be no need to
modify the factory set position of the long and
medium length fins. However, if spreading poor
quality product, or if you wish to detune the width
of spread (reduce the width), having adjustable
fins can be very useful.
If making an adjustment, both the left and
right spinners should have the same settings. A
13mm ring spanner will be required to loosen the
nyloc nuts on the bottom of the spinners.
The toe of the fin will need to line up with a
corresponding mark on the disc. Refer to Table 24
and Fig.25 for the appropriate fin position.
