arms and shoulders.  To reduce the risk of 

vibration-related injury:
1.  Anyone using vibrating tools regu-

larly 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 symptoms 

related to vibration (such as tingling, 

numbness, and white or blue fingers), 

seek medical advice as soon as pos-

sible.

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.

4.  Use tools with the lowest vibration 

when there is a choice between dif-

ferent processes.

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 tool as 

explained in this manual.  If abnormal 

vibration occurs, stop immediately.

  SAVE THESE 

INSTRUCTIONS.
