Note: Hold onto the center as you tap it loose
to avoid dropping it and damaging the tip or
the bedways.
NOTICE
To avoid premature wear of the dead center
or damage to the workpiece, always use
lower spindle speeds and keep the dead
center tip well lubricated.

Note: The scale on the tailstock handwheel
is marked in 0.025mm increments (approxi-
mately 0.001") with one full revolution moving
the quill 1.25mm (approximately 0.050").

Note: The force against the mounted
workpiece will fully seat the center's taper
into the quill. However, do not overly force
the center into the workpiece with the hand-
wheel—this will make removing the center
very difficult and could damage it.
