GROUNDING
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, prop-
erly 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 com-
plies with the applicable standards of
Underwriters Laboratories, Inc., the
Canadian Standard Association and
the National Electrical Code. Double
Insulated tools may be used in ei-
ther of the 120 volt outlets shown in
Figures B and C.
In specifi c countries, double insulated tools could
be used in the output
connections suitable
for the plug.
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 Cana-
da) 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.

Installing Side Handle
The side handle may be installed on either side
of the gear case. Position the side handle in the
location which offers best control and guard protec-
tion. To install, thread side handle into side handle
socket and tighten securely.
WARNING
To reduce the risk of injury
when grinding:
• ALWAYS use the proper guard.
• ALWAYS properly install the guard.
• ALWAYS hold the tool fi rmly with both
hands using the handles provided before
and during grinding.
• NEVER use a wheel that has been dropped.
• NEVER bang grinding disc onto work.
• NEVER grind without proper safety
equipment.
Installing, Removing and Adjusting the Guard
This tool is shipped with a guard. The guard must
be used when using the tool as a grinder. The guard
may be removed when using tool as a sander.
1. To
remove
the guard, unplug tool and remove
any accessories from spindle.
2. Press in the lock lever and rotate the guard to line
up the tabs on the grinder with the slots in the guard.
3. Press in the lock lever and lift the guard straight
up and away from the tool.
4. To
install
the guard, unplug the tool and remove
any accessories from the spindle.
5. Line up the tabs on the grinder with the slots in
the guard.
6. Press in the lock lever and press the guard onto
the tool.
7. To
adjust
the guard, press in the lock lever and
rotate the guard to one of fi ve detent slots.
WARNING
Only use accessories with
Maximum Safe Operating Speed rated at
least equal to the maximum speed marked
on the power tool. This speed is based on
the strength of the wheel, allowing for a
reasonable measure of safety. It is not meant
to imply a best or most effi cient operating
speed. Do not exceed the Maximum Safe
Operating Speed.
ASSEMBLY
