5. DO NOT USE ANYTHING TO STRESS THE GRINDING WHEEL.
6. USE A GRINDING WHEEL DRESSING TOOL to shape or remove glaze from grinding wheels.
7. ADJUST DISTANCE between wheel and tool rest to maintain at most a 1/8-inch (3.2 mm) separation as
the diameter of the wheel decreases with usage.
8. CONNECT TO A SUPPLY CIRCUIT protected by a circuit breaker or time-delay fuse.
9. SECURE THE BENCH GRINDER to its supporting surface to prevent the grinder from tipping over,
sliding, or walking on its supporting surface.
Replace a cracked wheel immediately.
Always use the guards and eye shields.

12. GUARD AGAINST ELECTRICAL SHOCK by preventing body contact with grounded surfaces. For
example: pipes, radiators, ranges, refrigerator enclosures.
13. DO NOT use wheels with incorrect size holes. NEVER use wheel washers or wheel screws that are
defective or incorrect, and NEVER touch a grinding wheel or other moving parts.
14. NEVER reach to pick up a workpiece, a piece of scrap, or anything else that is in or near the grinding path
of the wheel.
15. AVOID AWKWARD OPERATIONS AND HAND POSITIONS where a sudden slip could cause
your hand to move into the wheel. ALWAYS make sure you have good balance.
16. NEVER stand or have any part of your body in line with the path of the wheel.
