placement.

Cleaning instructions
a.
Clean individual shafts and pistons (only these parts) with soap solution or isopropanol. Then
rinse with distilled water.
b.
Allow the parts to completely dry and cool. Liquid residues in the shafts result in deviations in ac-
curacy.
c.
Re-grease pistons with a very thin coat of the grease supplied. For the central guide axis (Z), use
only the prescribed fluorine static grease.
d.
After assembling the unit, carry out a reference run (rEF).
