Knife change

Precise cuts are only possible with a sharp knife. The knife should be changed as soon as the quality and the accuracy of a cut are not in accordance with the standards expected from this cutting machine. Should the knife jam in the paper pile or leave grooves in the paper, it must be changed immediately. Knife life with normal paper is approximately 20 working hours: of course this will vary with different types of paper.

We recommend that purchase of a spare knife, so that a sharp knife is always available. This ensures that your machine remains operative even if the original knife has to be sent away for re - sharpening. Look for a professional re -sharpening service locally. Of course, your distributor knows one and can help you in this regard.

The knife change must be executed by one person only. The cutting edge of the knife is extremely sharp. In order to avoid injuries, the knife has to be handled with the utmost care. Transportation of knife is only permitted in specially designed wooden cases (see SAFETY RULES).
