Installation
X Place the new scale on a clean work surface.
X Attach the cover strip to the front side of the scale.
X Attach the double-sided adhesive tape to the back of the new scale. The surface to be fixed down
must be clean and free of grease.

area.
X Place the scale under the gantries in the machine.
X Pull the transparent cover strip back until you can see the drilling on the scale and have enough room
to feed in the adhesive device. Start from the left side (when viewed in the direction of transport).
