Tool Safety
Angle Grinder
DO NOT let comfort or familiarity with product (gained from repeated use) replace strict adherence to
grinder safety rules. If you use this tool unsafely or incorrectly, you can suffer serious personal injury.
1. Always use safety glasses or goggles.
2. Obtain permission from instructor before using the saw.
3. Always use proper guard with grinding wheel. A guard protects operator from broken wheel
fragments.
4. Accessories must be rated for at least the speed recommended on that may affect the tools
operation. If damaged, have the tool serviced before using. Many accidents are caused by poorly
maintained tools.
SPECIFIC SAFETY RULES
5. Hold tool by insulated gripping surfaces when performing an operation where the cutting tool may
contact hidden wiring or its own cord. Contact with a “live” wire will make exposed metal parts of the
tool “live” and shock the operator.
6. When using depressed center grinding wheels, be sure to use only fiberglass-reinforced wheels.
7. Ordinary sun glasses are NOT safety glasses.
9. 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.
10. Use only flanges specified for this tool.
11. Be careful not to damage the spindle, the flange (especially the installing surface) or the lock nut.
Damage to these parts could result in wheel breakage.
12. NEVER use tool with wood cutting blades or other saw blades. Such blades when used on a grinder
frequently kick and cause loss of control leading to personal injury.
13. Hold the tool firmly.
14. Keep hands away from rotating parts.
15. Make sure cord is clear of wheel. Do not wrap cord around your arm or wrist. If control of tool is lost,
cord may become wrapped around you and cause personal injury.
16. Make sure the wheel is not contacting the work piece before the switch is turned on.
17. 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.
18. Use the specified surface of the wheel to perform the grinding.
19. Watch out for flying sparks. Hold the tool so that sparks fly away from you and other persons or
flammable materials.
20. Do not leave the tool running. Operate the tool only when hand-held.
21. Do not touch the work piece immediately after operation; it may be extremely hot and could burn
your skin.
23. ALWAYS wear proper apparel including long sleeve shirts, leather gloves and shop aprons to protect
skin from contact with hot grindings.
24. Use of this tool to grind or sand some products, paints and wood could expose user to dust
containing hazardous substances. Use appropriate respiratory protection.
