If the motor should be subjected to excessive strain (e.g. continuous cutting of strong cardboard
with a dull knife), the power supply to the motor will be interrupted by the thermal overload
switch (#10).
The overload button will pop out a few mm. After a short cooling down period, the overload
button can be reset again.
Maintenance
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. Knife life with normal paper is approximately 20 working hours; of course, this
will vary with different types of paper.
We recommend the purchase of a spare knife, so that a sharp knife is always available. This
ensures that your machines 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, which are supplied with every spare
knife ordered from your local distributor.
The following description applies to model IDEAL 4810-11. Please note, that with models
IDEAL 4810 and IDEAL 5210 the re -set button (#12) must be pushed prior to activating the knife
with the two push buttons (#5).
1. Turn the cutting depth adjustment screw (#4) all the way to the left (-) and then a complete
turn to the right (+).
2. Bring the knife down by pressing both push button switches (#5). Release one of the switches
and turn main switch (#11) to position “0” (off). The knife stays in its lowest position on the
cutting stick (#2).
3. Remove knife screw (E). See illustration I.
4. Remove the securing screw (F) on the knife adjustment flap (#20). Lift up the flap (#20) and
turn out the three knife adjustment screws (X, Y, and Z) by approximately 5 mm (1 /4”). See
illustration II.
5. Turn main switch (#11) to position “|” (on). The knife carrier (#17) goes back to its home
position. Turn main switch back to “off” position.
6. Remove knife screws (B and D) and replace them with the two knife holders from the tool
box. Tighten securely.
7. Take out knife screws (A and C), loosen knife holders and lower the knife downwards from
the knife carrier (#17). Then, due to the length of the knife, a sideways movement between
the knife guide plates is required for removal.
8. Take out cutting stick (#2), turn, rotate or exchange it and place it back into machine.
IMPORTANT – Hook cutting stick into pin, which is located on left between the knife guide
plates.
