FEATURES
THE HEADSTOCK
The motor drives the Spindle via an internal tooth type belt. Spindle speed is variable,
and is regulated by the Speed Control Knob.
The spindle, is provided with an internal No.2 Morse taper to accommodate a centre
for use with a drive dog assembly when turning between centres.(See ‘Accessories’)
The Chuck Guard, is an essential component and must always be lowered into
place when using the lathe. A microswitch prevents the lathe from operating should
the Guard be raised.
The 3-Jaw, Self Centering Chuck is mounted on the Spindle Flange Adapter. To
remove the chuck, simply remove the three securing nuts to the rear of the flange
adapter allowing it to be pulled free together with the three mounting bolts.
The spindle flange adapter is bolted to the spindle flange with 3 Hex. socket head
screws, and should be removed when the Centre is used.

unscrewing the single securing screw.

by the Power Drive Control Knob, When the knob is turned clockwise, drive is
transmitted to the leadscrew and therefore the saddle, providing a power feed for
screw cutting or general turning operations.
