6.1 Adjust saw frame
If you receive straight and clean cut-
ting surfaces but the cuts are not 90°,
it is very likely that your saw frame
became outbalanced. In this case you
have to readjust it.
You can readjust the saw frame by
turning part No° (32) that regulates
within a tolerance level the descent angle of the saw frame.
