Angle Grinder Safety

• Inspect the grinder, disc, guard, and trigger before every use.
• Use cutting discs for cutting and grinding discs for grinding only.
• Ensure the guard is correctly positioned to protect from sparks and fragments.
• Hold the grinder firmly with both hands and brace yourself against kickback.
• Wear safety goggles, face shield, hearing protection, and gloves during use.
• Check the disc maximum RPM rating matches or exceeds the grinder speed.
• Clear combustible materials from the spark zone before starting work.
• Allow the disc to reach full speed before applying it to the workpiece.
• Disconnect the power before changing discs or adjusting the guard.
• Let the disc stop completely before putting the grinder down.

• DON'T remove or adjust the guard while the grinder is running.
• DON'T use a cutting disc for grinding or a grinding disc for cutting.
• DON'T use a disc that exceeds the grinder's maximum disc diameter.
• DON'T operate a grinder with a defective dead man switch.
• DON'T use a damaged, cracked, or warped disc — replace it immediately.
• DON'T grind near combustible materials without clearing or protecting them.
• DON'T force the disc into the material — let the tool do the work.
• DON'T operate a grinder one-handed — always maintain a two-hand grip.
• DON'T use an angle grinder without hearing and eye protection in place.
• DON'T point the spark stream towards other workers, fuel, or gas cylinders.
