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.
Fig. 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.
Fig. B Fig. 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.
Punch and Die Replacement
Dies should be replaced
about every third time the
punch is changed, or as
necessary. A plate wrench
is provided with tool.
1. Unplug tool and place
on a level surface.
2. Loosen collar with plate
wrench. Remove collar
and die support.
3. Punch Removal: Loos-
en the set screw with
2.5 mm allen wrench.
Remove punch and
discard.
4. Punch Installation: Align
punch detent with set
screw in punch hold-
er. Tighten set screw
securely to below the
surface of the punch
holder.
