OPERATIONS, CONT.
Make sure the live center in the tailstock
lines up with the spur center in the head-
stock before turning anything between the
centers. Failure to observe this step could
result in the workpiece being thrown from
the lathe. Serious personal injury could
occur if care is not taken.
Adjust the tool rest as close to the workpiece as
possible without actually coming into contact with
the workpiece. Test by hand-turning the work-
piece before starting the lathe. Ensure that the
lathe chisel is fully supported by the tool rest.
Support the lathe chisel on the tool rest with one
hand, while the other hand controls the chisel.

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).
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 should. Always start
at the slowest speed.
