ditions. For this reason, all the intervals are only valid for the authorised conditions.

Lubricate
Lubricate all slideways.

Cross table
Lubricate
Lubricate all blank steel parts. Use acid-free oil, for
example weapon oil or engine oil.
As required
Spindle nuts
Readjust
An increased clearance in the spindles of the crosstable can be
reduced by readjusting the spindle nuts. Refer to spindle nuts posi-
tion 66 and 71
The spindle nuts are readjusted by reducing the flank of screw
thread of the spindle nut with an adjusting screw. By readjusting a
smooth running move over the whole toolpath is to be assured, oth-
erwise the wear by friction between spindle nut /spindle would
increase considerably.
