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 accord-
ance with all codes and ordinances.
The plug and outlet should look like
Fig. A
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 Standard Asso-
ciation and the National Elec-
trical Code. Double Insulated
tools may be used in either of
the 120 volt outlets shown in
Fig. B Fig. C
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
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.

ASSEMBLY
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.
Removing and Replacing Quik-Lok
(Cat. No. 6523-21)
MILWAUKEE's exclusive Quik-Lok
instant fi eld replacement or substitution.
Fig. 1
1. To remove the Quik-Lok® Cord, turn the cord
nut 1/4 turn to the left and pull it out.
2. To replace the Quik-Lok® Cord, align the con-
nector keyways and push the connector in as
far as it will go. Turn the cord nut 1/4 turn to the
right to lock.
Selecting a Blade
Use MILWAUKEE Sawzall® Blades for best perfor-
mance. When selecting a blade, choose the right
type and length.
Many types of blades are available for a variety of
applications: cutting metal, wood, nail-embedded
wood, scroll cutting, roughing-in, and contours.
Many lengths are also available. Choose a length
long enough to extend beyond the shoe and your
work throughout the stroke. Do not use blades
less than 3-1/2" long since they won't extend
beyond the shoe throughout the stroke.
150'
For best performance and longest life, see "Acces-
sories" to select the best blade for the job.

Blade
Unplug the tool before changing blades. Be sure
the spindle and blade clamp areas are clean. Metal
chips and sawdust may prevent the Quik-Lok®
Blade Clamp from clamping securely.
1. Depending on the job, the blade may be inserted
with the teeth facing up or down. To install a
blade, twist collar in the direction of the arrow
while inserting the blade into the clamp until the
tang butts against the collar.
2. Release collar and the spring loaded mechanism
will clamp the blade fi rmly in place.
3. Twist collar in the opposite direction of the arrow
to ensure that the blade is locked into the clamp.
4. Tug on blade to make sure it is securely locked
in place.
5. To remove a blade, twist collar in the direction
of the arrow while pulling on the blade. Be
careful when handling hot blades.
Quik-Lok® Blade Clamp Maintenance
• Periodically clean dust and debris from the Quik-
Lok® Blade Clamp with dry compressed air.
• If the collar resists twisting, twist itr back and forth
to shake debris loose.
• Periodically lubricate Quik-Lok® Blade Clamp with
® Cords
dry lubricant such as graphite.
® Cords provide
Removing broken blades from the Quik-Lok®
Blade Clamp
Unplug the tool before removing blades. Broken
blades can be removed by the following methods.
• Point the tool downward, twist the collar, and shake
the tool up and down (do not turn the tool on while
your fi ngers are holding the blade clamp open).
The shank of the broken blade should drop out of
the clamp.
• If shaking the tool doesn't work:
In most cases, a corner of the broken blade will
extend beyond the blade clamp. Simply twist the
collar and pull the broken blade out of the clamp
by this corner.
• If the broken stub doesn't extend far enough to be
grabbed by its corner, use a thin blade with small
teeth (such as a metal cutting blade) to hook the
blade that is jammed in the clamp while twisting
the collar and pull it out.
OPERATION
WARNING
To reduce the risk of injury,
wear safety goggles or glasses with side shields.
Adjustable Pivot Shoe
The shoe can be adjusted forward or backward
to six positions to take advantage of the unused
portion of the blade or for special jobs requiring
low blade clearance.
