SPECIFIC SAFETY PRECAUTIONS FOR GRINDING MACHINES
1. DO NOT operate your machine until it is completely assembled and installed according to
the instructions.
2. If you are not familiar with the operation of grinding machines obtain advice from your
supervisor or instructor or another qualified person.
3. Only use grinding wheels or attachments rated higher than 3600 rpm with a 5/8" (16mm) arbor
on this machine.
4. NEVER use a chipped or cracked wheel. Always inspect each wheel before mounting it on
the grinder. If during inspection you discover a damaged grinding wheel; replace it immediately.
5. DO NOT over tighten wheel nuts.
6. Always maintain a distance of 1.5mm or less between the wheel and the tool rest. Adjust the
tool rests as the wheels decrease in size.
7. Ensure the tool rests are tightened so they cannot move while in use.
8. NEVER grind on a cold wheel. The grinder should always be run for at least one minute before
applying work to it.
9. NEVER grind on the side of the wheel. Always grind on the face of the wheel only.
10. NEVER apply coolant directly to a grinding wheel, it may cause the bonding to fail. If the
work piece becomes hot, dip it into a water pot to cool it down.
11. HOT SPARKS ARE A HAZARD! NEVER carry out grinding operations near flammable
material of any type (ie solid, gas, liquid).
12. Always make sure the spark guards and eye shields are in place, that they are properly
adjusted and secured.
13. Keep the sparks guards close to the wheels and re-adjust them as the wheels wear.
14. Ensure the soft washer and the flanges furnished with the grinder, are used to mount any
attachments (grinding wheels, wire brushes, buffing wheels, etc) onto the shaft.
15. Always stand to one side of the grinder when starting the machine.
16. Avoid awkward hand positions where a sudden slip could cause the hands to come into
contact with a grinding wheel, wire brush etc.
17. If the wheel requires dressing, dress only the front of the wheel, do not dress the sides.
18. DO NOT use any attachment that causes the machine to vibrate. If after changing grinding
wheels or adding attachments, the machine does vibrate; remove the recently replaced item and
change again.
19. Grinding creates heat. DO NOT touch the work face of the work piece until you are sure it has
cooled down sufficiently.
