9. Make sure the abrasive disc or the wheel is not
contacting the workpiece before the switch is
turned on.
10. Watch out for flying sparks. Hold the tool so
that sparks fly away from you and other
persons or flammable materials.
11. Do not leave the tool running. Operate the tool
only when hand-held.
12. Do not touch the workpiece immediately after
operation; it may be extremely hot and could
burn your skin.
13. Ventilate your work area adequately when you
perform sanding operations.
14. ALWAYS wear proper apparel including long
sleeve shirts, leather gloves and shop aprons
to protect skin from contact with hot
grindings.

16. Always use proper guard with grinding wheel.
A guard protects operator from broken wheel
fragments.
17. When using depressed center grinding wheels,
be sure to use only fiberglass-reinforced
wheels.
18. Check the wheel carefully for cracks or
damage before operation. Replace cracked or
damaged wheel immediately. Run the tool
(with guard) at no load for about a minute,
holding tool away from others. If wheel is
flawed, it will likely separate during this test.
19. Before using the tool on an actual workpiece,
let it run for a while. Watch for vibration or
wobbling that could indicate poor installation
or a poorly balanced wheel.
20. Use the specified surface of the wheel to
perform the grinding.
