To reduce the risk of vibration-related injury: 1. Anyone using vibrating tools regularly or for an extended period should first be examined by a doctor and then have regular medical check- ups to ensure medical problems are not being caused or worsened from use. Pregnant women or people who have impaired blood circulation to the hand, past hand injuries, ner- vous system disorders, diabetes, or Raynaud’s Disease should not use this tool. If you feel any medical or physical symptoms related to vibration (such as tingling, numbness, and white or blue fingers), seek medical advice as soon as possible. 2. Do not smoke during use. Nico- tine reduces the blood supply to the hands and fingers, increasing the risk of vibration-related injury. 3. Wear suitable gloves to reduce the vibration effects on the user.
