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 ap-
propriate 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:
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.

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 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.

Blades and Blade Selection

The blade dimensions required for the band saws
are: .020" thickness, 1/2" width and 35-3/8" in
length. The special .020" thickness reduces fl exure
fatigue and provides maximum tooth life. To maxi-
mize cutting life, use a blade with the correct pitch
(teeth per inch) for the specifi c cutting job.
Blades are available in several pitches. To select the
proper blade, three factors should be considered:
The size, shape, and type of material to be cut.
The following suggestions are for selecting the
right blade for various cutting operations. Keep in
mind that these are broad guidelines and that blade
requirements may vary depending upon the specifi c
size, shape and type of material to be cut. Gener-
ally, soft materials require coarse pitch blades and
hard materials require fi ne pitch blades. Use coarse
pitch blades for thick work and fi ne pitch blades for
thin work. It is important to keep at least three teeth
in the cut (see "Typical Application").
