Vibration Safety

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 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.

5.  Include vibration-free periods each day of work.
6.  Grip tool as lightly as possible (while still keeping 

safe control of it).  Let the tool do the work.

7.  To reduce vibration, maintain the tool as 

explained in this manual.  If any abnormal 
vibration occurs, stop use immediately.
