Additional Safety for Surface Grinders

WHEEL SPEED RATING. Wheels operated at a faster speed than rated for may break or fly apart. Before mounting a new wheel, be sure the wheel RPM rating is equal or higher than the speed of the grinder.

WHEEL FLANGES. Only use the flanges included with the grinder when mounting wheels. Other flanges may not properly secure the wheel and could cause the wheel to fly off or break apart.

RING TEST. Perform a "ring test" on grinding wheels before installation to ensure that they are safe to use. A wheel that does not pass the ring test may break or fly apart during operation.

STARTING GRINDER. If a wheel IS damaged, it will usually fly apart shortly after start-up. To pro- tect yourself, always stand away from the grinding wheel when turning the machine ON and allow the wheel to gain full speed before standing in front of it.

CRACKED WHEEL. Cracked wheels may break and fly apart during operation. Replace cracked wheels immediately!

PROTECTIVE CLOTHING. Protect skin from fly- ing sparks by wearing close-fitting long sleeves and buttoned-up shirt. In case of falling heavy objects, wear leather, non-skid boots with added toe protection.

GRINDING MAGNESIUM. Grinding material with magnesium content may increase the risk of fire or explosion. Before grinding material with magne- sium content, review all available safety informa- tion that pertains to grinding magnesium, including the National Fire Protection Association standard NFPA 480, “Storage, Handling and Processing Magnesium.”

WORKPIECE CONTACT. A heavy impact against the grinding wheel can cause it to break or fly apart, causing serious personal injuries. Avoid jamming the workpiece into the wheel to reduce this risk.

LUNG PROTECTION. Grinding produces haz- ardous dust, which may cause long-term respira- tory problems if breathed. Always wear a NIOSH approved dust mask or respirator when grinding, and use coolant when possible to minimize this risk.

HAND/WHEEL CONTACT. Grinding wheels have the capability of removing a lot of skin fast. Make sure the workpiece is securely clamped to the table, then position your hands a safe dis- tance away when grinding. Avoid wearing gloves as they may get caught in the grinding wheel and cause even more serious entanglement injuries.

DUST COLLECTION. DO NOT connect a sur- face grinder to a dust collection system that is used with woodworking machines. Sparks emit- ted from the grinding process may ignite wood particles, resulting in fire or explosion. Only use

ametal-specific dust collection system with this machine.

COOLANT USAGE. Use the correct personal protection equipment when handling coolant. Follow federal, state, and fluid manufacturer requirements for proper disposal.

EYE PROTECTION. Grinding causes small par- ticles to become airborne at a high rate of speed. ALWAYS wear ANSI-approved eye and face pro- tection when using this machine.
