6. Re-tighten the outer pivot screw. Screw should be snug but not over tightened.
Over tightening may prevent the upper blade from rotating.
7. Rotate the shaft by hand, using the inboard shaft extending from the assembly
(Fig. 19d). The knife should rotate freely, and will make a metallic shearing
sound during rotation.
8. Insert a strip of the material to be cut so it extends from both sides of the knife.
Test by rotating the knife shaft again to cut the material.
9. If the two parts of the material are still attached by thread, the knife is damaged
and must be replaced.
10. If your test only cuts the material part way through, an additional adjustment is
required.
11. Retest and repeat Steps 9 and 10 above.
