20. WARNING: Some dust created by power sanding, 

sawing, grinding, drilling, and other construction 

activities, contains chemicals known to the State 

of California to cause cancer and birth defects or 

other reproductive harm.  Some examples of these 

chemicals are: 

•  Lead from lead-based paints 

•  Crystalline silica from bricks and cement or other 

masonry products 

•  Arsenic and chromium from chemically 

treated lumber 

Your risk from these exposures varies, 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.

)

21. WARNING: The cord of this product contains 

lead and/or di (2-ethylhexyl) phthalate (DEHP), 

chemicals known to the State of California 

to cause cancer, and birth defects or other 

reproductive harm. Wash hands after handling.  

(California Health & Safety Code § 25249.5, 

et seq.

)

22. The warnings, precautions, and instructions 

discussed in this instruction manual cannot cover all 

possible conditions and situations that may occur.   

It must be understood by the operator that 

common sense and caution are factors 

which cannot be built into this product, 

but must be supplied by the operator.

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 medical or 

physical 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.  Use tools with the lowest vibration when there 

is a choice between different processes.

4.  Include vibration-free periods each day of work.

5.  Grip workpiece as lightly as possible (while still 

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

6.  To reduce vibration, maintain the tool as 

explained in this manual.  If any abnormal 

vibration occurs, stop use immediately.

 SAVE THESE INSTRUCTIONS.
