SPECIFIC SAFETY RULES
• Use the power tool, accessories and tool bits
etc., in accordance with these instructions,
taking into account the working conditions
and the work to be performed. Use of the power
tool for operations different from those intended
could result in a hazardous situation.
SERVICE
• Have your power tool serviced by a qualifi ed
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.
• Use auxiliary handles supplied with the tool.
Loss of control can cause personal injury.
• Wear ear protectors with impact drills. Expo-
sure to noise can cause hearing loss.
• Hold tools by insulated gripping surfaces when
performing an operation where the cutting tool
may contact hidden wiring or its own cord.
Contact with a “live” wire will make exposed metal
parts of the tool “live” and shock the operator.
• Keep hands away from all cutting edges and
moving parts.
• 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 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.
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 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.
Double Insulated Tools: Tools with Two Prong
Plugs
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.

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 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.

Installing Bits into Keyless Chucks
These tools are equipped with a hand-tightening
keyless chuck. Always unplug the tool before install-
ing or removing bits.
1. To open the chuck jaws,
turn the sleeve counter-
clockwise.
When using drill bits, allow
the bit to strike the bottom
of the chuck. Center the bit
in the chuck jaws and lift it
about 1/16" off of the bottom.
When using screwdriver bits, insert the bit far
enough for the chuck jaws to grip the hex of the
bit.
2. To close the chuck jaws, hold the collar while
turning the sleeve clockwise. Tighten securely.
WARNING To reduce the risk of injury,
do not grasp the bit while the chuck is rotating
or while the bit is falling from the chuck.
