Please protect your cutter from moisture, dust, draughts and direct sunlight (to prevent
possible media detection and epos readout issues). It is best to keep your machine away
from open windows and air-conditioners.
See to it that there is an adequate space around the cutter so that ventilation is not
obstructed.
Avoid unnecessary vibrations and set up your cutter on a level surface.
Be sure to have some free space on each side of the Kona to ease the operating of it.

Product overview
2.6 Machine version
Each machine has its own version number existing
out of a letter (version) and a number (revision),
e.g. A2.
Some parts integrated in a machine with a
higher version number, might not be
downwards-compatible with machines
containing a lower version number.
Example: Parts tagged with version C are NOT downwards compatible with machines
from version A and B
Some parts integrated in a machine with a higher revision number, are downwards
compatible with machines containing a lower revision number.
Parts that are different due to different version-numbers, will be tagged on the sparepart-list,
with a serial number. (refer to the table below)
When spare parts have to be ordered, please always verify the serial-number on the cutter,
with those on the sparepart-list, to ensure you use the correct part!
Serial numbers Machine version number
LA-1909xx A1
LA-1910xx and LA-1911xx A2
LA-1912xx A3
LA-1001xx to LA-1007xx A4
The version label of the machine can be found behind the right side cover.
Refer to Cover removal > Side covers on page 28
Note
The list of differences between the versions can be requested at our service
department (service@mutoh.eu
