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.

15. Use of this tool to grind or sand some

products, paints and wood could expose
user to dust containing hazardous sub-
stances. Use appropriate respiratory pro-
tection.

IF USED AS A GRINDER

16. Always use proper guard with grinding

wheel.

A guard protects operator from bro-

ken 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 sep-
arate during this test.

19. Before using the tool on an actual work-

piece, 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.
