General Procedure

1. Ensure that the pedestal grinder is stable
2. Ensure that all the guards are in place before turning on
3. Check to see if the tool rest is within 1/16" of the grind wheel. If you are unsure if it is within 1/16" of the wheel, adjust it as close to the wheel as you can.
4. Make sure that the wheel turns freely before using
5. Turning on the wheel, stand to the side of the machine and wait for it to come to full speed
6. Bring work into contact with the grinding wheel slowly and smoothly, without bumping
7. When grinding move back and forth across the face of the wheel. This prevents even wear on the wheel and prevents grooves from forming in your work piece
8. Once done using, turn off the grinder and wait for it to come to a complete stop

Safety

• Ensure that you are wearing the popper attire for grinding
  • Sleeves rolled up
  • Hoodie draw strings tucked in
  • Safety glasses
  • Face shield
  • NO gloves (gloves = bye bye fingers)
  • Always follow the general shop dress code (closed toed shoes, hair above collar, no dangles, etc.)

It is ABSOLUTELY CRITICAL that you do NOT have ANY DANGLING items when using this machine. It will eat them and the things they are attached to (i.e. you).

• When grinding always keep the material flat on the tool rest. If you do need to grind an edge that cannot be accessed while the tool is flat on the tool rest, use a hand grinder or get a shop supervisor to help you.
• Don't let your hands or fingers make contact with the spinning wheels.
• Don't use this tool to grind a small part.
• Parts can get very HOT while grinding so be patient and take short brakes between grinds.
• Never attempt to grind aluminum on a grinder setup for steel. This could cause a grinding wheel to explode.
• Never attempt to use a grinding wheel that has been cracked, chipped, or damaged.

Maintenance

General maintenance

The gaps between the wheel and grinding fixture rests should be no more than a 1/16" inch. As the wheel wears the technician will need to adjust the rests.
