Clean and lubricate the spindle.
Using a soft and lint-free cloth, wipe off the dirty
grease over the whole length of the spindle
(press firmly on the specified position at the
brake to move the axis up and down).
Lubricate the spindles slightly with the supplied
grease BEM 34-32 by means of the black brush (9
mm wide). Do not apply too much grease. Move
manually the Z-axis up and down to apply
evenly the grease. Wipe off any excess.
