position. The scale must be positioned at the lay-on edge.

gantry).

X Move the head plate so that you can fix the rest of the scale.

damaged.

X Carefully lever the scale upwards on one side

with the scriber and then gently extract the

scale.

X Remove any adhesive residues with ethanol.

The surface to be fixed down must be clean

and free of grease.

NOTE: Cover strip on scale

X A cover strip protects the front of the scale. Remove this cover strip AFTER installation.

ATTENTION: Take care when handling the incremental scale.

Do not touch the incremental tracks with bare fingers.

ATTENTION: Make sure that no blisters or uneven areas are formed.

If this does occur, the scale must be removed and replaced with a new scale.
