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 out-
let, 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 insula-
tion system which satisfi es OSHA requirements
and complies with the applicable standards of
Underwriters Laboratories,
Inc., the Canadian Stan-
dard Association and the
National Electrical Code.
Double Insulated tools may
be used in either of the
120 volt outlets shown in
Figures B and C.

EXTENSION CORDS

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.

WARNING
To reduce the risk of injury,
always unplug tool before attaching or remov-
ing accessories or making adjustments. Use
only specifi cally recommended accessories.
Others may be hazardous.
Installing Collets
MILWAUKEE Die Grinders feature a special collet
and collet nut. The collet must be attached to the
collet nut before installing the collet asembly to the
tool. Be sure that the collet size matches the size of
the mounted wheel mandrel you will use, otherwise
the collet may break.
1. To assemble, place collet on an even surface,
take nut and place over collet (Fig. 1).
Fig. 1
2. Position nut squarely over collet (Fig. 2).
Fig. 2
3. Snap nut and collet together by fi rmly applying
downward pressure onto assembly with the
palm of hand (Fig. 3).

ASSEMBLY
Installing Grinding Points
MILWAUKEE offers a complete line of grinding
points for fi nish grinding, beveling, sharpening and
de-burring (see "Accessories").

1. Remove dust and debris from the collet body
before inserting grinding points.
2. Insert the collet with the collet nut attached into
the collet body. Thread the collet nut onto the
spindle but do not tighten it yet.
3. Clean the grinding point mandrel, then insert it
a minimum of 3/4" into the collet. The mandrel
will overhang the collet and the grinding point
about 1/2".
4. Hold the spindle shaft steady with a 1/2" open
end wrench and securely tighten the collet nut
with an 11/16" open end wrench.
5. Reverse the procedure when removing the
grinding point.
WARNING
To reduce the risk of in-
jury, always securely tighten the collet to the
grinders and clean mandrels before inserting
them into the collet. Otherwise the high-speed
rotation of the tool could force the grinding
point to fl y out of the collet.
