GENERAL POWER TOOL
SAFETY WARNINGS
WARNING
Read all safety warnings, instructions, illustrations and specica-
tions provided with this power tool. Failure to
follow all instructions listed below may result in
electric shock, re and/or serious injury. Save all
warnings and instructions for future reference.
The term "power tool" in the warnings refers to your
mains-operated (corded) power tool or battery-oper-
ated (cordless) power tool.
WORK AREA SAFETY
• Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
• Do not operate power tools in explosive atmo-
spheres, such as in the presence of ammable
liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
• Keep children and bystanders away while operat-
ing a power tool. Distractions can cause you to lose
control.
ELECTRICAL SAFETY
• Power tool plugs must match the outlet. Never modify
the plug in any way. Do not use any adapter plugs with
earthed (grounded) power tools. Unmodied plugs
and matching outlets will reduce risk of electric shock.
• Avoid body contact with earthed or grounded
surfaces, such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded.
• Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of
electric shock.
• Do not abuse the cord. Never use the cord for car-
rying, pulling or unplugging the power tool. Keep
cord away from heat, oil, sharp edges or moving
parts. Damaged or entangled cords increase the risk
of electric shock.
• When operating a power tool outdoors, use an
extension cord suitable for outdoor use. Use of a cord
suitable for outdoor use reduces the risk of electric shock.
• If operating a power tool in a damp location is
unavoidable, use a ground fault circuit interrupter
(GFCI) protected supply. Use of an GFCI reduces
the risk of electric shock.
PERSONAL SAFETY
• Stay alert, watch what you are doing and use
common sense when operating a power tool. Do
not use a power tool while you are tired or under
the inuence of drugs, alcohol or medication. A
moment of inattention while operating power tools may
result in serious personal injury.
• Use personal protective equipment. Always wear eye
protection. Protective equipment such as a dust mask,
non-skid safety shoes, hard hat or hearing protection used
for appropriate conditions will reduce personal injuries.
• Prevent unintentional starting. Ensure the switch
is in the o-position before connecting to power
source and/or battery pack, picking up or carrying
the tool. Carrying power tools with your nger on the
switch or energizing power tools that have the switch
on invites accidents.
• Remove any adjusting key or wrench before turning
the power tool on. A wrench or a key left attached to a
rotating part of the power tool may result in personal injury.
• Do not overreach. Keep proper footing and balance
at all times. This enables better control of the power
tool in unexpected situations.
• Dress properly. Do not wear loose clothing or
jewelry. Keep your hair and clothing away from
moving parts. Loose clothes, jewelry or long hair can
be caught in moving parts.
• If devices are provided for the connection of dust
extraction and collection facilities, ensure these are
connected and properly used. Use of dust collection
can reduce dust-related hazards.
• Do not let familiarity gained from frequent use of
tools allow you to become complacent and ignore
tool safety principles. A careless action can cause
severe injury within a fraction of a second.
POWER TOOL USE AND CARE
• Do not force the power tool. Use the correct power tool
for your application. The correct power tool will do the
job better and safer at the rate for which it was designed.
• Do not use the power tool if the switch does not turn
it on and o. Any power tool that cannot be controlled
with the switch is dangerous and must be repaired.
• Disconnect the plug from the power source and/
or remove the battery pack, if detachable, from
the power tool before making any adjustments,
changing accessories, or storing power tools. Such
preventive safety measures reduce the risk of starting
the power tool accidentally.
• Store idle power tools out of the reach of children and
do not allow persons unfamiliar with the power tool
or these instructions to operate the power tool. Power
tools are dangerous in the hands of untrained users.
• Maintain power tools and accessories. Check for
misalignment or binding of moving parts, breakage
of parts and any other condition that may aect the
power tool’s operation. If damaged, have the power
tool repaired before use. Many accidents are caused
by poorly maintained power tools.
• Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
• Use the power tool, accessories and tool bits etc.
in accordance with these instructions, taking into
account the working conditions and the work to be
performed. Use of the power tool for operations dierent
from those intended could result in a hazardous situation.
• Keep handles and grasping surfaces dry, clean
and free from oil and grease. Slippery handles and
grasping surfaces do not allow for safe handling and
control of the tool in unexpected situations.
BATTERY TOOL USE AND CARE
• Recharge only with the charger specied by the
manufacturer. A charger that is suitable for one type
of battery pack may create a risk of re when used with
another battery pack.
• Use power tools only with specically designated
battery packs. Use of any other battery packs may
create a risk of injury and re.
• When battery pack is not in use, keep it away from
other metal objects, like paper clips, coins, keys, nails,
screws or other small metal objects, that can make
a connection from one terminal to another. Shorting
the battery terminals together may cause burns or a re.
• Under abusive conditions, liquid may be ejected from
the battery; avoid contact. If contact accidentally
occurs, ush with water. If liquid contacts eyes,
additionally seek medical help. Liquid ejected from
the battery may cause irritation or burns.
• Do not use a battery pack or tool that is damaged or
modied. Damaged or modied batteries may exhibit
unpredictable behavior resulting in re, explosion or
risk of injury.
3
• Do not expose a battery pack or tool to re or
excessive temperature. Exposure to re or temperature
above 265°F (130°C) may cause explosion.
• Follow all charging instructions and do not charge
the battery pack or tool outside the temperature
range specied in the instructions. Charging im-
properly or at temperatures outside the specied range
may damage the battery and increase the risk of re.
SERVICE
• Have your power tool serviced by a qualied repair
person using only identical replacement parts. This
will ensure that the safety of the power tool is maintained.
• Never service damaged battery packs. Service
of battery packs should only be performed by the
manufacturer or authorized service providers.
SPECIFIC SAFETY RULES FOR
SAWZALL
TM
• Hold power tool by insulated gripping surfaces,
when performing an operation where the cutting
accessory may contact hidden wiring. Cutting ac-
cessory contacting a “live” wire may make exposed
metal parts of the power tool “live” and could give the
operator an electric shock.
• Use clamps or another practical way to secure
and support the workpiece to a stable platform.
Holding the work by hand or against your body leaves
it unstable and may lead to loss of control.
•
WARNING
To reduce the risk of injury in applications that produce a consider-
able amount of dust, use an OSHA compliant dust
extraction solution in accordance with the solution’s operating instructions.
• Always use common sense and be cautious when
using tools. It is not possible to anticipate every
situation that could result in a dangerous outcome.
Do not use this tool if you do not understand these
operating instructions or you feel the work is beyond
your capability; contact Milwaukee Tool or a trained
professional for additional information or training.
• 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 specially designed to
lter out microscopic particles.

3. To stop the tool, release the trigger. Make sure the
blade comes to a complete stop before removing
the blade from a partial cut or laying the tool down.
Electric Brake
The electric brake engages when the trigger is released, causing the blade to stop and allowing you
to proceed with your work. Generally, the saw blade
stops within two seconds. However, there may be a
delay between the time you release the trigger and
when the brake engages. Occasionally the brake may
miss completely. If the brake misses frequently, the
saw needs servicing by an authorized MILWAUKEE
service facility. You must always wait for the blade
to stop completely before removing the saw from
the workpiece.
slide the release lever up. Insert the blade into the
clamp until the tang butts against the collar.
2. Release the lever and the spring loaded mechanism will clamp the blade rmly in place.
3. Tug on blade to make sure it is securely locked in
place.
4. To remove a blade, slide the release lever up
and pull the blade from the tool. 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, slide the release lever back and
forth to shake debris loose.
• Periodically lubricate Quik-Lok® Blade Clamp with
a dry lubricant such as graphite.
Removing broken blades from the
Quik-Lok® Blade Clamp
Broken blades can be removed by the following
methods.
• Remove battery pack before removing blades.
• Point the tool downward, slide up and hold the
release lever, and shake the tool up and down (DO
NOT turn the tool on while your 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. Slide up and hold
the release lever, 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 holding up
the release lever, and pull it out.
WARNING
To reduce the risk of injury, blades
must extend beyond the shoe and
workpiece throughout the stroke. Blades may
shatter if they impact the workpiece or shoe.

General Cutting
For straight or contour cutting from an edge, line
the blade up with your cutting line. Before the blade
contacts the workpiece, grasp the handle rmly and
pull the trigger. Then guide the tool along your cutting
line. Always hold the shoe at against the workpiece
to avoid excessive vibration.
Cutting Metals
Begin cutting at a slow speed, gradually increasing
speed as you cut. When cutting into metals or hard
materials that can not be cut from an edge, drill a
starting hole larger than the widest part of the blade.
WARNING
To reduce the risk of explosion,
electric shock and property damage, always check the work area for hidden gas
pipes, electrical wires or water pipes when mak-
ing blind or plunge cuts.
Plunge Cutting
Your MILWAUKEE Sawzall® is ideal for plunge cutting directly into surfaces that can not be cut from
an edge, such as walls or oors. Plunge cutting may
be done two ways depending on how the blade is
inserted. Column A shows how to plunge cut with the
teeth of the blade facing downward. Column B shows
how to plunge cut with the teeth of the blade facing
upward. Do not plunge cut into metal surfaces (see
"Cutting Metals").
1. Insert the blade into the tool.
If you inserted the blade with the teeth facing
downward, hold the tool as shown in Column A,
resting the edge of the shoe on the workpiece.
If you inserted the blade with the teeth facing up-
ward, hold the tool as shown in Column B, resting
the edge of the shoe on the workpiece.
2. With the blade just above the workpiece, pull the
trigger. Using the edge of the shoe as a pivot, lower
the blade into the workpiece as shown.
3. As the blade starts cutting, raise the handle of
the tool slowly until the shoe rests rmly on the
workpiece. Then guide the tool along your cutting
line to acquire the desired cut.
NOTE: To make plunge cutting easier, use a heavy
gauge blade and install the blade with the teeth facing
upward as shown in Column B.
