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).
The following steps apply to models IDEAL 4850-90 and IDEAL 6550-90. Please note that with
the models IDEAL 4850, IDEAL 5250 and IDEAL 6550, the re-set button (#14) must always be
pushed prior to activating the knife with the two push buttons.
a. Turn the cutting depth adjustment screw (#4) all the way to the left (-) and then a complete
turn to the right (+).
b. Bring the knife down by pressing both push buttons switches (#5 and #15). Release one of
the switches and turn main switch (#13) to position “0” (off). The knife stays in its lowest
position on the cutting stick.
