tool may contact hidden wiring or its own cord. 
Cutting accessory contacting a “live” wire may make 
exposed metal parts of the power tool “live” and

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. 

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.

 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 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.

* Based on limiting the line voltage drop to 
fi ve volts at 150% of the rated amperes.

Adjusting the Side Handle Position
1.  Loosen the side handle by unscrewing the side 

handle grip until the side handle rotates freely. 

2.  Rotate the side handle to the desired position.  
3.  Tighten the side handle grip securely.

Setting the Depth Gauge
1.  Press in the clamping lever.
2.  Slide the depth gauge rod backward or forward 

until it is set for the desired depth. 

  NOTE: The drilling depth is the distance between 

the tip of the bit and the tip of the rod.

3.  Release the clamping lever.

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 ap-
propriate outlet, properly installed and 
grounded in accordance with all codes 
and ordinances. The plug and 
outlet should look like those in 
Figure A.

Tools marked “Double Insulated” do not require 
grounding. They have a special double insulation 
system which satisfi es OSHA requirements and 
complies with the applicable standards of Under-
writers Laboratories, Inc., the 
Canadian Standard Associa-
tion and the National Electri-
cal Code. Double Insulated 
tools may be used in either of 
the 120 volt outlets shown in 
Figures B and C.

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 venti-
lated area, and work with approved safety equip-
ment, such as those dust masks that are specially 
designed to fi lter out microscopic particles.
