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 outlet, properly installed
and grounded in accordance with
all codes and ordinances. The plug
Fig. A
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 Underwrit-
ers Laboratories, Inc., the Cana-
dian 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.

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 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.

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.
WARNING
To reduce the risk of injury,
wear safety goggles or glasses with side
shields.
In all cutting operations, keep the shear at right
angles to the surface of the workpiece and the
back as low as possible for fast cutting. Use an
even forward pressure to insure effi cient operation.
To obtain the least amount of metal distortion and
smoothest edge, keep waste portion of metal to the
right of the shear. Cutting line should be lubricated
before cutting 16 gauge steel or heavier.
Blade Clearance
The clearance between the blades is not set at the
time of manufacture. Cleaner edges and longer
blade life will result when the gap is properly set for
the gauge of the metal to be cut. Use 20% of the
material thickness for an approximate blade clear-
ance setting. Make minor adjustments, if necessary.

To adjust the gap:
1. Unplug the tool and loosen the lower blade
clampling screw 1/3 of a turn with the socket
wrench provided.
2. Turn the blade positioning screw, on the side of
the yoke, in or out to decrease or increase the
gap.
NOTE: If lowerblade clamping screw is loose
more than a 1/3 of a turn, the blade clearwance
may be misadjusted.
3. Measure the clearance with the feeler gauge
provided.
4. When the desired setting has been achieved,
tighten the blade clamping screw and locking
nut on the blade positioning screw.

Sharpening Blades
The cutting angles must be maintained. When
blade replacement is necessary always replace
the blades in sets. This will produce cuts of con-
sistent quality.
