SPECIFIC SAFETY RULES
SPECIFICATIONS
•Hold power tool by insulated gripping surfaces, 
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.
 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.

GROUNDING
WARNING
 Improperly connecting the 
grounding wire can result in the risk of elec-
tric shock. Check with a qualifi ed electrician 
if you are in doubt as to whether the outlet is 
properly grounded. Do not modify the plug 
provided with the tool. Never remove the 
grounding prong from the plug. Do not use 
the tool if the cord or plug is damaged. If 
damaged, have it repaired by a MILWAUKEE 
service facility before use. If the plug will not 
fi t the outlet, have a proper outlet installed by 
a qualifi ed electrician.
Grounded Tools: Tools with Three Prong Plugs
Tools marked “Grounding Required” have a three 
wire cord and three prong grounding plug. The 
plug must be connected to a properly grounded 
outlet (See Figure A). If the tool should electrically 
malfunction or break down, grounding provides a 
low resistance path to carry electricity away from 
the user, reducing the risk of electric shock.
The grounding prong in the plug is connected 
through the green wire inside the cord to the 
grounding system in the tool. The green wire in the 
cord must be the only wire connected to the tool's 
grounding system and must never be attached to 
an electrically “live” terminal.
Your tool must be plugged into 
an appropriate outlet, properly 
installed and grounded in accord-
ance with all codes and ordinances. 
The plug and outlet should look like 
those in Figure A.
Double Insulated Tools: 
Tools with Two Prong Plugs
Tools marked “Double Insulated” do not require 
grounding. They have a special double insula-
tion system which satisfi es OSHA requirements 
and complies with the applicable standards of 
Underwriters Laboratories, Inc., 
the Canadian Standard Asso-
ciation and the National Elec-
trical Code. Double Insulated 
tools may be used in either of 
the 120 volt outlets shown in 
Figures B and C.
Grounded tools require a three wire extension 
cord. Double insulated tools can use either a two 
or three wire extension cord. As the distance from 
the supply outlet increases, you must use a heavier 
gauge extension cord. Using extension cords with 
inadequately sized wire causes a serious drop in 
voltage, resulting in loss of power and possible tool 
damage. Refer to the table shown to determine the 
required minimum wire size.
The smaller the gauge number of the wire, the 
greater the capacity of the cord. For example, a 14 
gauge cord can carry a higher current than a 16 
gauge cord. When using more than one extension 
cord to make up the total length, be sure each cord 
contains at least the minimum wire size required. 
If you are using one extension cord for more than 
one tool, add the nameplate amperes and use the 
sum to determine the required minimum wire size.
Guidelines for Using Extension Cords
• If you are using an extension cord outdoors, be 
sure it is marked with the suffi x “W-A” (“W” in 
Canada) to indicate that it is acceptable for outdoor 
use.
• Be sure your extension cord is properly wired 
and in good electrical condition. Always replace a 
damaged extension cord or have it repaired by a 
qualifi ed person before using it.
• Protect your extension cords from sharp objects, 
excessive heat and damp or wet areas.
READ AND SAVE ALL 
INSTRUCTIONS FOR FUTURE USE.
* Based on limiting the line voltage drop to fi ve volts at 
150% of the rated amperes.
