Lubrication Schedule - Promac BD-8BM Mode D'emploi

Fig 18
To eject the live centre, fully retract the
tailstock quill.
7.8 Steady and follow rest (optional)
The steady rest:
serves as a support for longer shafts
and ensures a safe and chatter free
operation.
The steady rest is mounted on the bed
way with a locking plate.
Tighten knurled screws (3, Fig 19) so
that fingers (2) are snug but not tight
against work piece. Tighten nuts (1).
Lubricate the fingers to prevent
premature wear.
Fig 19
The follow rest:
is mounted on the saddle and follows
the movement of the tool. It prevents
flexing of long and thin work pieces
under pressure from the tool (Fig 20).

Set the fingers snug but not overly
tight. Lubricate the fingers to prevent
premature wear.
