26. When sanding, remove the tool rest from the machine, apply light pressure and use a slow speed to avoid
heat build up.
27. When turning large diameter pieces, such as bowls, always operate the lathe at low speeds. See the speed
recommendation chart.
28. Do not attempt to engage the spindle lock pin until the spindle has stopped. If leaving the machine area, turn
it off and wait until the spindle stops before departing.
29. Make no adjustments except speed changes with the spindle rotating and always disconnect the machine
from the power source when performing maintenance to avoid accidental starting or electrical shock.
30. Provide for adequate space surrounding work area and non-glare, overhead lighting.
31. When stopping the lathe, never grab the part or faceplate to slow it down. Let the work coast to a stop.
