Never use a grinder without a guard. If an abrasive wheel breaks while rotating, it can cause a serious injury.
Wear safety glasses or goggles, or a face shield (with safety glasses or goggles) to protect against flying particles. Gloves, aprons, metatarsal safety boots, and respiratory protection may be required, depending on the work.
Ensure the floor around the work area is clean.
Do not use wheels that are cracked or those that excessively vibrate.
Do not operate grinder on wet floors.
Use both hands when holding the grinder.
Keep the power cord away from the grinding wheel and the material being ground.
Avoid using grinders near flammable materials.
Do not clamp portable grinders in a vise for grinding hand-held work.
Do not force wheels onto a grinder that is the wrong size or change mounting hole sizes.
Do not tighten the mounting nut excessively.
Do not put the grinder on the floor or working surface until the wheel has stopped turning.
