18.1.4 Fastening the Digital Read Out (only for model ED400FDDIG)
18.1.5 Aligning the Lathe
18.1.6 Checking the Jaw Chuck
When mounting a chuck or face plate, first make sure that the cam-lock studs are
properly fixed. Otherwise, the chuck/face plate may never be removed again later
because the cam-lock studs have become twisted.

After installation and commissioning, it is recommended to check
the alignment and levelling of the machine before using it for the
first time. In order to ensure working accuracy, the alignment and
levelling should be repeated at regular intervals.
To level the machine, use a precision spirit level according to DIN
877 with an accuracy of ±0.02 mm or ±0.04 mm to 1000 mm. This
allows the horizontal position of the machine axis to be checked with
sufficient accuracy in both the longitudinal and transverse
directions.
Repeat the horizontal check a few days after initial commissioning
and every six months thereafter.
NOTICE
Do not use cast iron chucks. Use ductile iron chucks only. Before
disassembling the jaw chuck, place a stable board or chuck cradle
under the spindle to protect the precision-ground surfaces.

The digital read out (DRO) has to be mounted
