pacemaker interference or pacemak-

er failure.  In addition, people with 

pacemakers should:

Your risk from these exposures var-

ies, depending on how often you do 

this type of work.  To reduce your 

exposure to these chemicals: work in 

a well ventilated area, and work with 

approved safety equipment, such as 

those dust masks that are specially 

designed to filter out microscopic 

particles.  (California Health & Safety 

Code § 25249.5, 

et seq.

)

WARNING: Handling the cord on 

22.

Vibration safety

This tool vibrates during use.  Re-

peated 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:
Anyone using vibrating tools regu-

1. 

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.
Do not smoke during use.  Nico-

2. 

tine reduces the blood supply to the 

hands and fingers, increasing the risk 

of vibration-related injury.
