GROUNDING
WARNING
Improperly connecting the ground-
ing wire can result in the risk of
electric shock. Check with a qualied electrician
if you are in doubt as to whether the outlet is
properly grounded. Do not modify the plug pro-
vided 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 t the outlet, have a
proper outlet installed by a qualied electrician.
Grounded Tools (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 mal-
function 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 appro-
Fig. A
priate 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 (Two-Prong Plugs)
Tools marked “Double Insulated” do not require
grounding. They have a special double insulation
system which satisfies OSHA requirements and
complies with the applicable standards
Fig. B
Fig. C
of Underwriters Laboratories, Inc., the
Canadian Standard 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 suf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 qualied
person before using it.
• Protect your extension cords from sharp objects,
excessive heat and damp or wet areas.

ASSEMBLY
WARNING
To reduce the risk of injury, always
unplug tool before changing or
removing accessories.
To reduce the risk of injury when grinding, always
use properly installed guards.
Removing/Installing/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 detent tab and rotate the guard clock-
wise until the tabs on the grinder line up with the
slots in the guard.
3. 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. The arrows on the grinder and guard
will align.
6. Press in the detent tab and press the guard onto
the tool. Rotate guard counterclockwise into rst
detent slot.
