2. Allow machine to work at its own rate.
3. Keep cutting accessories sharp. Replace as
needed.
4. Check that RPM feed rate chart for appropriate
rates for operation.
5. Adjust gears so there is a small amount of play
and the gears move freely and smoothly when
the Chuck is rotated by hand.
6. Wear ANSI-approved safety goggles and NIOSH-
approved dust mask/respirator while blowing dust
out of motor using compressed air.
7. Eliminate use of extension cord. If an extension
cord is needed, use one with the proper diameter
for its length and load. See Extension Cords in
GROUNDING section.
