Vibration Hazard:
This tool vibrates during use. Repeated or
long-term exposure to vibration may cause
temporary or permanent physical injury,
SAFETY OPERATION MAINTENANCESETUP
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 checkups 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.
