trimmed. The Air Blast is out of synch. The Trimmer cannot trim even a thin booklet.

flags.
Remedy: Bend Bracket back in shape.
Long term solution: New Cable Duct will protect underlying parts.

Squeaking Knife
Symptom: Squeaking sound at every trim cycle:
Cause: Steel against steel surfaces are always prone to induce vibration. Of obvious causes it is
not possible to lubricate the surfaces.
Short term remedy: Lubricate upper knife with candle stick.
Long term solution: Tests are presently running with low-friction knives. These knives are PVD-
treated (Physical Vapor Deposition), which makes the surface harder with a lower friction.
