SAFETY WARNINGS
Read all safety warnings, instruc-
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.
tions, illustrations and specica-
WORK AREA SAFETY
• Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence of flam-
mable liquids, gases or dust. Power tools cre-
ate sparks which may ignite the dust or fumes.
• Keep children and bystanders away while operating
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 carrying,
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 ac-
cidents 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.

age, always check the work area for hidden gas
pipes, electrical wires or water pipes when mak-
ing blind or plunge cuts.
MILWAUKEE Sawzall® reciprocating saw 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 blade is inserted with the teeth facing downward,
hold the tool as shown in Column A, resting the
edge of the shoe on the workpiece.
If blade is inserted with the teeth facing upward,
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 the 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.
