7.1 Knockout Bar
The knockout bar is used to remove the drive centre from the headstock
spindle. Insert knockout bar into hole at opposite side from drive centre, see
Fig 7.1
.
To remove the revolving centre from the tailstock, loosen locking handle
and rotate the hand wheel counter-clockwise to retract the spindle into the
body of the tailstock. The revolving centre will be pushed out of the spindle,
Fig 7.2
.
7.2 Fitting the Faceplate to the Headstock
Thread the faceplate clockwise onto the headstock spindle and tighten
faceplate with supplied spanner,
Fig 7.3
.
To remove the faceplate, hold the spindle with the supplied spanner to stop
the spindle from turning and loosen the faceplate with supplied spanner.
Unthread the faceplate anti-clockwise from the headstock spindle.
7.3 Adjusting the Tool Rest
The tool rest base can be easily moved along the lathe bed. Loosen locking
lever counter clockwise, slide the tool rest base to it's new position, and
tighten locking lever clockwise.
To adjust the height of the tool rest, loosen the locking arm, raise or lower
the tool rest then tighten locking arm,
Fig 7.4
.
Please note: Position the tool rest as close to the work piece as
possible. It should be 3.5mm above the centre line of
the workpiece.
To adjust clamping action of the tool rest base, remove base and adjust nut
clockwise to tighten and counterclockwise to loosen,
Fig 7.5
. Tightening
the nut will increase the sensitivity of the cam mechanism and increase the
clamping force. Loosening the nut will reduce the clamping force of
the cam.

Indexing Lock
The indexing lock is positioned on the front of the headstock for ease of use.
The headstock indexing feature has 12 equally spaced positions. The spring
loaded locking pin assembly is engaged by turning the knob a half turn
allowing it to drop into the desired position. To disengage, lift the lock knob
up and turn a half turn either direction.
Fig.7.6
.
The 12 position indexing feature allows accurate pattern work on projects
such as straight fluting, grooving, drilling, lay out and more.
To use the indexing feature, disengage the locking knob by lifting up and
rotating a half turn. The pin hole will engage in the closest pin available.
Please note: The indexing mechanism should not be used as a
method of holding the spindle whilst removing accessories such
as face plates, chucks etc. Always hold the spindle with a spanner
on the spindle nose when removing accessories.
