3-13 Parallel Adjustment of Backgauge to the Knife

Backgauge is fixed as the gap between square
on the knife and backgauge should be less
than 0.1mm. When the gap is less than 0.1 mm
because of parts replacement or use for many
years, adjust as follows.
1. Cut a book actually and check the difference
between right and left.
- Touch the paper neither right nor left side
gauge, but only backgauge when cutting.
- The difference between right and left can be
seen when the paper is folded in the middle
and lapped.
- Another way to see the gap between right
and left. Cut the paper of thickness over
1cm. Reverse the upper part of the paper
and lap on the lower one. Step results and
the difference becomes easier to be seen.
2. Loosen lock lever.
3. Loosen lock nuts of parallel adjust screws
for a half turn.
4. Rotate parallel adjust screws and adjust the
parallelism to the knife.
When one of the parallel adjustment screws
was loosened, fasten another for the same
amount as loosened one.
5. Fasten the lock lever after adjustment.
