Vibration Precautions

This tool vibrates during use.  Repeated 

or long-term exposure to vibration may cause 

temporary or permanent physical injury, par-

ticularly to the hands, arms and shoulders.  To 

reduce the risk of vibration-related injury:

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 cir-

culation to the hand, past hand injuries, 

nervous system disorders, diabetes, or 

Raynaud’s Disease should not use this 

tool.  If you feel any symptoms related 

to vibration (such as tingling, numbness, 

and white or blue fingers), seek medical 

advice as soon as possible.

  SAVE THESE 

INSTRUCTIONS.
