when performing an operation where the fas-
tener may contact hidden wiring. Fasteners 
contacting a “live” wire may make exposed metal 
parts of the power tool “live” and could give the 
operator an electric shock.

Exposure to noise can cause hearing loss.

• Use only sockets and other accessories spe-

cifi cally designed for use on impact wrenches 
and drivers. Other sockets and accessories might 
shatter or break causing injury.

• Maintain labels and nameplates. These carry 

important information. If unreadable or missing, 
contact a MILWAUKEE service facility for a free 
replacement. 

• WARNING: Some dust created by power sanding, 

sawing, grinding, drilling, and other construction 
activities contains chemicals known to cause 
cancer, birth defects or other reproductive harm. 
Some examples of these chemicals are:

• lead from lead-based paint
• crystalline silica from bricks and cement and other 

masonry products, and

• 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 spe-
cially designed to fi lter out microscopic particles.
