Removing the OMI-2 window
It is not necessary to remove the OMI-2 from
the machine when adjusting the switches or
installing new parts.
To remove the OMI-2 window:
CAUTION: DO NOT remove the window by
twisting or rotating.
1. Clean the OMI-2 to ensure that no debris
enters the unit.
2. Remove the four cover screws using the
2.5 mm A/F hexagon key supplied with
the kit. Two screws are short and two are
long. Two of the cover holes are threaded
A and two are plain B.
3. The window fits tightly in the OMI-2 body
and is removed using the two long screws
which are inserted into the threaded
holes A.
Tighten each screw a few turns at a time
to lift the window evenly. When it is clear
of the body, remove the window and
screws completely.
4. Discard the used window and O-ring.
