Cutting and Drilling Bottom Foil
Consult the chart on page 13 to see if you need to short-

" (140 mm). Make
sure you cut the end nearest the existing holes. Deburr
the foil after cutting.
Tip: there are three dimples in the bottom foil. The upper dimple is a
guide for cutting the foil. Wrap tape evenly around the foil so the top
edge of the tape runs through the center of the upper dimple. Line the
hacksaw blade up with this edge of the tape. The side of the blade
facing the lower part of the foil should run through the center of the
dimple.
Drill two holes using a

WARNING
If you make any cuts in the foils
be sure to carefully
clean all shavings from inside
the foils. Failure to deburr or
clean the inside of the foils
may cause them to seize to the
connector during installation.
