Usage Notes
- Use the guard
- Use eye protection at all times
- Grinding is loud, ear protection is suggested, hearing damage may result
- First contact is often surprisingly strong, grip extra tight
- Grinding metal gets hot, pause to let it cool or douse it in water
- DO NOT wear gloves, they are a tangling hazard and will result in worse injuries
- Angle metal downward or it can kick out at you
- Do not load motor down so that it slows, exert less pressure and grind slower if an audible speed difference is heard in RPM
- Adjust tool rests to within 3 mm (1/8 in.)
