the variable speed selector allows the adjust-
ment of the spindle rpm. Before turning the lathe
on, make sure the speed selector knob is set
at the lowest rpm (turn counterclockwise). see
figure 14.
once the lathe is turned on, slowly increase the
rpm 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.

hammer. Be careful not to split the workpiece.
see figure 13. Wood with splits along the
grain may fly off during the operation. With
dense wood, drill a hole at the centers and
score lines with a saw blade for the spur.
Do not press the workpiece too firmly with
the tailstock 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.
remember to choose the correct speed for
your particular turning project. as a gen-
eral rule, the larger the workpiece diameter,
the slower the speed. always start on slow
speed.
