 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 
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 
Figures B and C.

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.

* Based on limiting the line voltage drop to fi ve volts at 

150% of the rated amperes.

MILWAUKEE's exclusive Quik-Lok

®

 Cords provide 

instant fi eld replacement or substitution. 

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. 
For best performance and longest life, see “Acces-
sories” to select the best blade for the job.

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 

dry lubricant such as graphite.

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.

2. To lock the shoe in position, push the shoe 

release lever up.

DO NOT OPERATE SAWZALL WITHOUT SHOE. 
STRIKING THE SPINDLE AGAINST WORK MAY 
DAMAGE THE RECIPROCATING MECHANISM.

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.
