lathe unplugged when not in use and before making
adjustments
5. The proper speed should be selected for the diameter
and hardness of the material. In general, roughing
stock and beginning cuts are done at low speeds.

headstock handwheel before power is turned on to be
sure it can run clear of the tool rest. All adjustments to
tool rest are to be made when machine is
COMPLETELY stopped.
Wood Lathe Safety Guidelines
9. The lathe tool rest should be set 1/4 of an inch or less
from the rough stock. The tool rest should be 1/8 of an
inch above the center of and parallel to the stock.
9. Be sure that you have selected the proper sharp tools
for the operations and that the handles are secure.
9. Hold the lathe turning tool firmly down against the
tool rest.
9. Never use your fingers to check the work for
roundness while the lathe is running, especially during
roughing operations. Stop the lathe to check the
progress.

13. The tool rest shall be removed for all sanding
operations.
13. Wear a dust mask when performing sanding
operations.
