PAGE NOISE PRECAUTIONS
1.
Prolonged exposure to noise levels above 85 dBA is hazardous to hearing.
Always wear hearing protection when operating or working around the Concrete
Vibrator when it is running.
Vibration Hazard
This tool vibrates during use. Repeated or long-term exposure to vibration may
cause temporary or permanent physical injury, particularly to the hands, arms
and shoulders. 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,
nervous 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. Nicotine 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.
4.
Use tools with the lowest vibration when there is a choice between different
processes.
5.
Include vibration-free periods each day of work.
