WARNING!
Before starting the drilling-milling machine you have to check that there is no danger for
the staff and the drilling-milling machine is undamaged.
5.2 Inspection and maintenance
The type and extent of wear depends to a large extent on individual usage and service condi-
tions. For this reason, all the intervals are only valid for the authorised conditions.

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 position 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, otherwise the wear by friction between
spindle nut /spindle would increase considerably.
