Do not press too firmly or the bearings will
bind and overheat. Likewise, do not adjust
too loosely or the workpiece will spin off
the lathe. Use good judgement. Serious
personal injury could result if care is not
taken.

workpiece, insert the spur center (with the
attached workpiece) into the headstock spin-

the spindle before tapping the spur center in.

stock close to the end of the workpiece and
lock it into place.

The variable speed selector allows the adjust-
ment of the spindle R.P.M. Before turning the
lathe on, make sure the speed selector knob is set
at the lowest R.P.M. (turn counterclockwise). See
Figure 7.
Once the lathe is turned on, slowly increase the
R.P.M. of the lathe by turning the speed selector
knob clockwise. Make sure that your finger is
poised on the STOP button, just in case there’s a
problem. The lathe should run smoothly, with little
or no vibration or rubbing noises. Strange or
unnatural noises should be investigated and cor-
rected before operating the machine further.
If you cannot easily locate the source of an
unusual noise or vibration, contact our service
department for help.

Remember to choose the correct speed for
your particular turning project. As a gener-
al rule, the larger the workpiece diameter,
the slower the speed. Always start at the
slowest speed.
