1. Wear Personal Protective Equipment (PPE) such as safety glasses, safety goggles, face shields, gloves and proper clothing as appropriate. No loose clothing, long hair or jewelry is allowed in the shop.

2. Do not operate any grinder without the instructor’s permission.

3. Be aware of the position of the on/off switches and emergency STOP button.

4. Always check the clearance of the tool rest before starting work. Clearance should never be more than 3mm (1/8 inch). Always set the tool rest clearance when the wheel is not turning.

5. When mounting or replacing any grinding wheel, always ensure that it fits properly on the spindle. Never use a grinding wheel that is loose on the shaft.

6. In securing the wheel to the spindle be sure that the blotters are affixed to both sides of the wheel and that washers and nuts are of the correct size.

7. When starting up any grinding wheel, stand to one side out of line with the wheel especially if it is a new one.

8. Only replace a grinding wheel with one that has the same speed rating. Excessive speed on lower speed rated grinding wheels can cause the wheel to shatter.

9. Only grind on the face of the wheel, Use the entire face to avoid grooving the wheel.

10. Always feed the work into the wheel gradually. Too much pressure or striking the wheel suddenly may cause it to fracture.

11. Shut off machine immediately if it begins to chatter or vibrate. Never use tools or hands to stop any grinder. Report chattering and vibration to the teacher.

AT ALL TIMES – IF IN DOUBT, SEE YOUR INSTRUCTOR
