SPECIFIC SAFETY RULES
•Hold power tool by insulated gripping surfaces,
when performing an operation where the cut-
ting accessory may contact hidden wiring or
its own cord. Cutting accessories contacting a
"live" wire may make exposed metal parts of the
power tool "live" and could give the operator an
electric shock.
• DANGER: Keep hands away from cutting area
and the blade. Keep your second hand on
handle. If both hands are holding the saw, they
cannot be cut by the blade.
• Maintain labels and nameplates. These carry
important information. If unreadable or missing,
contact a MILWAUKEE service facility for a free
replacement.
• WARNING: Some dust created by power sanding,
sawing, grinding, drilling, and other construction
activities contains chemicals known to cause
cancer, birth defects or other reproductive harm.
Some examples of these chemicals are:
• lead from lead-based paint
• crystalline silica from bricks and cement and other
masonry products, and
• arsenic and chromium from chemically-treated-
lumber.
Your risk from these exposures varies, depending
on how often you do this type of work. To reduce
your exposure to these chemicals: work in a well
ventilated area, and work with approved safety
equipment, such as those dust masks that are spe-
cially designed to fi lter out microscopic particles.
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.
Double Insulated Tools:
Tools with Two Prong Plugs
Fig. A
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 Underwriters Laboratories, Inc.,
the Canadian Standard Asso-
ciation and the National Elec-
trical 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 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 changing or re-
moving accessories. Only use accessories
specifi cally recommended for this tool. Others
may be hazardous.
Blades and Blade Selection
The blade dimensions required for the band saws
are: .020" thickness, 1/2" width and 44-7/8" 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.
• For tough stock 3/16" up to
10 Teeth per Inch
3-1/4" in diameter or width.
• For tough stock 5/32" to 3/4" in
14 Teeth per Inch diameter or width.

ASSEMBLY
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. Generally, 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").
WARNING
Do not touch blade imme-
diately after use. Blade will be hot.
Changing Blades
1. UNPLUG THE TOOL BEFORE REMOVING OR
INSTALLING BLADES.
2. Turn the tension lock handle located on the front
of the saw 180° counterclockwise. This releases
the tension on the blade for easy removal.
3. Remove the blades from the pulley fi rst and then
from the guides.
4. To install a new blade, with the pulleys facing
up, insert the blade between the rollers and the
faces of the guides, making sure that the teeth
on the left side of the tool point towards the rear
of the tool.
5. With one hand, hold the blade in place between
the rollers and the guides and use the other hand
to position the blade around the pulleys. Be sure
that the blade lies freely within the guard channel
before starting the tool motor.
6. Turn the tension lock handle 180° clockwise to
lock the position. This will secure the blade on
the pulleys.
BE SURE THAT THE BLADE IS PROPERLY
SEATED ON THE PULLEYS BEFORE START-
ING THE CUT.
